Floristic analysis of Rattan species available in the 9 districts of Manipur State was conducted during the period from 2000 to 2005. During the survey, 14 species were collected, 6 species were found to be new records (Calamus erectus Roxb.; C. palustris Griff.; C. longisetus Griff.; C. viminalis Willd.; C. guruba (Becc.-Ham.) ex-Mart. and Daemonorops kurzianus Becc.). Maximum number of 5 species were collected from Tamenglong, Churachandpur and Imphal East District; 4 species were collected from Senapati, Chandel and Imphal West District; 3 species from Ukhrul District and 2 species from Thoubal and Bishnupur District respectively. Importance value index (IVI) of all the 14 Rattan species was calculated. The least IVI was recorded in Calamus erectus Roxb.(27.94) and its population type is accidental type, highest IVI was found in) Calamus pseudotenuis Becc. (237.44) and population is expanding type. Species distribution and floristic analysis were studied for the conservation steps of Rattans of Manipur.- Stachytarpheta urticifolia Sims, a New Snakeweed Record for the Flora of Manipur, India

New forests created on sodic wastelands, consisting of different community structure ameliorate the soil at various degrees according to productivity and diversity status. Three such forested sites were selected at Banthra Research Station of National Botanical Research Institute, Lucknow, India with different productivity and diversity indices descending from site I (S1) to III (S3), which were compared with a control (non forested) sodic soil site. Importance value index (IVI) decreased from 320 to 150 from site I to III. Shannon-Wiener's general diversity index was greatest in site I (1.85) and lowest in site III (1.37). Population density, basal area and biomass also declined accordingly. Dominant genera in these Forest stands were Acacia, Albizia, Dalbergia, Terminalia, Bauhinia and Syzygium whereas grasses/forbs viz.Sporobolus, Desmostachya and Dactyloctenium were common on barren sodic land. A remarkable reduction in soil pH and exchangeable sodium percentage (67-73%) was noticed in afforested sites compared to the control as a result of combined effect of increased diversity and productivity. Individual effects of diversity or productivity were measured as 42% and 58%, respectively in soil amelioration. The soil fertility increased 2 to 3 times in organic carbon and 2.7 to 3.7 times in total nitrogen content on afforested sites. However, these improvements were greatest in surface soil (0.15 m) for C and N (68 & 73%) in comparison to lower depths (51 & 65%). Among the exchangeable cations, Na+ reduced by 41-57% from the control in afforested sites (I and II) while Ca++ content increased of 38-68% in these sites. In general, available Zn, Fe and Mn contents increased in forested sites I and II whereas Cu decreased significantly in site II but remains at par on site I from the control. A rapid ch!lnge in soil properties occurred on surface soil even on poor afforested site while the rate of improvement at depths below 0.3 m depicted a slow amelioration process. A combined effect of both biomass productivity and species diversity of about 92% ameliorated the soil more significantly instead of individual factors, which should be taken into account for the rehabilitation of such sodic soil sites.- Leonotis nepetaefolia R.

Leonotis nepetaefolia R. Br. (Laminaceae) is an attractive, symmetrical, annual medicinal plant. A brief description of the plant is described in the present article. The plant is believed to be a native of Africa and the distribution extends to tropical Asia and America. It has been cultivated in Brazil since long. The plant seems to have naturalized in India. Traditionally, the leaf is used in rheumatic affections and also serves as a tonic. Flower heads are used against scalds, burns, ringworm, and some skin diseases. Crushed ischolar_main is applied locally for facilitating breast milk to a mother after childbirth. Seeds are used in fever. It has also got the anticancer, antioxidant and antibacterial properties. In India, it grows wild but not common. In recent years, India has given due attention on this plant to develop it's agrotechniques for commercial cultivation. Accordingly, responsibilities were entrusted with the NBPGR Regional Station, Shillong since 1999.- The Family Lamiaceae of Manipur, India

Economic viability of the tasar silkworm rearing rely on leaf quality and most vitally on timely supply of quality tasar seed called Dfls (Disease Free Layings) in suitable brushing schedule of the region. But there exists a short supply of 74.02 1akh Dfls (51.4%) against an estimated demand of 144 lakh Dfls, and this is the major constraint in utilizing the full potential of 111.60 lakh ha natural tasar flora of the country. Existing four tier and wired together seed multiplication system in India needs a multipronged redressal measures, especially at P1 level. Further, turning nonfunctional Pilot Projet Centres into operational and establishing their pragmatic linkages with private graineurs of the area, demarcation of a distinguished "Seed Cocoon Zone", involving operational women SHGs and working NGOs for generation of additional seed cocoons, creation of Para workers group/lead farmers, beefing up the backward and forward linkages by State sericulture mechanism to manage demand-supply and cost-realization process, incentive support to the tribals for biodiversity conservation, realization of carbon credits, large scale propagation of tasar eco-races on natural Sal flora, creating water harvesting system, inter cultivation of medicinal plants in economic tasar food plantation, HRD initiatives, clusterisation for systemic extension services, protection of natural tasar habitats, proliferation of tasar culture under National Mission for Green India under NAPCC etc., are some of the interventions, which are discussed in this communication to streamline the Indian or tropical tasar (Antheraea mylitta Durry) seed sector in India.Keywords

This paper presents the case study about economxy and ecological sustainability of stop dams constructed in Noradehi (Wildlife) Forest Division, Sagar. This Wildlife Division includes 1197 km2 of geographical area and it includes the ports of Sagar, Damoh and Narsingpur Districts of Madhya Pradesh. Under eco-development approach stop dams were constructed to solve the minor irrigation problem of villagers. The native rural population of the area are very poor and mainly depend on agriculture for their livelyhood. All the stop dams in the study are masonry structures of 2m height. The benefit/cost ratio (B/C) of stop dams have been evaluated. The benefit was calculated by deducting the value of produce before the construction from the value of produce after the construction of dam. The study revealed that these dams are economically viable as they give their cost recovery as quickly as in one year time. These dams are ecologically sustainable as these dams do not create adverse effects on environment viz. submergence of forest land, loss of flora and fauna, risk of reservoir induced seismicity, problem of rehabilitation, problem of change in micro-climate etc. Thus these dams prove to be very promising and will have tremendous scope for betterment of socio-economic rural upliftment.- Economic Analysis of Agroforestry Model Adopted by Tribal of Orissa : India

Trial has been framed to examine the economics of growing teak and cashew nut along with upland paddy in four combinations. The data trends up to 7 years of plantation were extrapolated to project the economic profit using standard economic analysis methods to interpret the benefits of various tree crop systems. The prediction has been done at 15th and 45th year (rotation age) at 7% and 15% discounting rate. The Net Present Value (NPV) predicted at rotation was found highest in land use with Agri-silviculture (teak + paddy) at 7% rate Rs 7,24,699/ha where as at 15% rate of discounting the highest NPV was observed in Agri-horticulture (cashew nut + paddy) Rs 45,255/ha, followed by Silvi-horticulture, Agri-silviculture and lowest in Agri-silvi-horticulture Rs 27,289/ha. The benefit cost ratio (BCR) was found higher 3.64 and 1.98 respectively at the 15th year in case of Silvi-horticulture (teak + cashew nut) at two extreme of discounting (7 and 15%) than that found in the other three agroforestry combinations. At rotation age of 45 years the highest BCR (6.33 and 2.64) was also found in Silvi-horticulture (teak + cashew nut) combination at 7% and 15% discounting respectively and it was found lowest in cashew nut+ paddy (4.42) at 7% and teak + cashew nut + paddy (1.78) at 15%- NLCP: A Heuristic for Priority Assignment Policy in Distributed Real Time Database System

Distributed database technology and real - time databases have been important areas of research in the recent days. It has been advised that many benefits can be obtained by integrating real - time and distributed database technologies. This paper deals with an important aspects of transaction processing in distributed real time databases, namely the problem of assigning priorities to transaction and as well as sub - transaction. We will present an efficient heuristic for assigning priorities to parent transaction as well as their child named cohorts or sub - transaction. We will also give the analysis of the heuristic with suitable example and show that how the priorities can be assigned.Keywords

The wide spread cultivation of acridity free and high yielding cultivars of elephant foot yam (Amorphophallus paeoniifolius Dennst.) has led to severe problem of leaf blight disease, throughout the country. The difficulty to control with chemical means after its outbreak, particularly in rainy season, leaves us with the only option to use resistant cultivars. Therefore, in order to find resistant sources in the available germplasm, an experiment was conducted at the Main Experiment Station of the Department of Vegetable Science, Narendra Deva University of Agriculture and Technology, Kumarganj, Faizabad, UP, during 2005-06 and 2006-07. Altogether, 49 genotypes of elephant foot yam, collected from different parts of the country, were screened against Phytophthora leaf blight, caused by Phytophthora colocasiae Racib., under artificial epiphytotic conditions. The per cent disease intensity (PDI) was recorded following the 0-5 scale, as suggested by Chester (1950), and the Area Under Disease Progress Curve (AUDPC) was also calculated. The results thus obtained indicated that none of the genotypes was found in resistant category. Out of the 49 genotypes tested, 9 genotypes namely, NDA-3, NDA-12, NDA-13, NDA-21, NDA-25, NDA-26, NDA-29, NDA-30, and NDA-45, showed moderate susceptibility.Keywords

Ten genetically diverse parents of chickpea were crossed in half diallel fashion to study the morpho- physiological parameters during four growth stages in a field experiment conducted at Indian Institute of Pulses Research, Kanpur. Wide variation was observed among all the parameters during all the four growth stages.Highest yielding parents (K850, JG62 and N59) and hybrids ( ICC10035 x K850, ICC987 x K850 and ICC 4914 x JG62) were relatively short statured and exhibited greater initial growth leading to higher leaf area index, greater ischolar_main length and weight. Dry matter production and crop growth rate were slow during early vegetative phase in all the parents as well as hybrids and increase progressively as the duration/ temperature advanced. A comparison of relative growth rates in parents and hybrids indicated more rapid RGR in early part of season implying faster rate of leaf development and profuse branching which are instrumental in producing better photosynthetic apparatus in hybrids before pod formation.Keywords

This experiment was laid out in March 2008 at college campus, P.G. College Ghazipur (U.P.) in Randomized Block Design with three replications. In this investigation four varieties with three spacing for finding best variety with optimum spacing was studied. Characters studied regarding growth attributes were plant height (cm), number of leaves per plant, and number of branches, while regarding to yield attributes, number of pods, dry weight of pods and fresh weight of pods. The data revealed significant differences among the varieties and spacing for all the traits. Among four varieties viz., V.R.O.-6, Parbhani Kranti, Arka Anamika and Arka Abhay, variety V.R.O.-6 proved its dominance over other varieties regarding to both attributes (yield and growth) while among three spacing viz., 30×15,30×30 and 30×45 cm, spacing of 30×15 cm was found best and optimum for okra crop. Among all interactions V.R.O.-6 with spacing 30×15 cm performed best. On the basis of this investigation it is concluded that V.R.O.-6 with spacing 30×15 cm should be adapted in eastern U.P.Keywords

Elephant foot yam is a long duration crop, taking about 7-8 months to realise its full yield potential. This is the reason it requires a nutrient management package which can supply nutrients for longer duration till the maturity of the crop, which is only possible through the incorporation of organic sources of nutrients to the soil. The present experiment, therefore, was conducted at the Main Experiment Station of the Department of Vegetable Science, Narendra Deva University of Agriculture and Technology, Kumarganj, Faizabad, UP, during 2006-07 and 2007-08, with the aim to formulate an integrated package of nutrient management involving both inorganic as well as organic sources of nutrients for elephant foot yam under eastern Uttar Pradesh conditions. Ten treatments, using NDA-9 as the experimental material were tested viz., T0 : Absolute control (no fertilizer), T1 : 100:60:80 kg NPK/ha, T2 : T1 + 50 kg N/ha substituted through FYM, T3 : T1 + 50 kg N/ha substituted through vermicompost, T4 : 125:60:100 kg NPK/ha, T5 : T4 + 50 kg N/ha substituted through FYM, T6 : T4 + 50 kg N/ha substituted through vermicompost, T7 : 150:60:120 kg NPK/ha, T8 : T7 + 50 kg N/ha substituted through FYM and T9 : T7 + 50 kg N/ha substituted through vermicompost. On the basis of both the year's data, it was found that the application of 150:60:120 kg NPK/ha + 50 kg N substituted through FYM (T8) proved to be the best, which resulted in the maximum canopy spread (77.00 cm), maximum corm weight per plant (2.64 kg) as well as total corm yield (44.24 q/ ha). It was established that continued crop production potential of soils has a direct relationship to its organic fraction of the soil, and therefore, organic sources of nutrients, in any form, either alone or in combination, may be advocated for use, at least for elephant foot yam.Keywords

Surface, subsurface and mine water collected from rural, urban, industrial and coal mining areas of Dhanbad district have been analysed to assess the major ion chemistry, the weathering and geochemical processes controlling the water composition and suitability of water for domestic, industrial and agricultural uses. Ca, Mg, and HCO3 dominate the chemical composition of the water chemistry. However, in the mine water and water samples collected from mining areas, high concentration of SO4 has been observed. Water chemistry of the study area strongly reflects the dominance of continental weathering and higher concentration of SO4, Cl and TDS in some samples indicates mining and anthropogenic impact on water quality. The high contribution of (Ca+Mg) to the total cations, relatively high (Na+K)/TZ+ ratio (0.27) and low equivalent ratio of (Ca+Mg)/(Na+K) i.e. 3.6 suggest combined influence of carbonate and silicate weathering. The higher values of C-ratio for most of the surface and subsurface water signify that carbonic acid weathering is the major proton producer in these waters. However, the low C-ratio for the mine water (average 0.22) and the waters collected near the coal mining areas suggests that sulphide oxidation and/or coupled reactions (involving both carbonic acid weathering and sulphide oxidation) control the chemical quality in the mining areas. The quality assessment of surface and subsurface water shows that water is suitable for domestic use with few exceptions. The calculated values of SAR, RSC and sodium percentage indicate that water can be used for irrigation without any hazard.Keywords

The CERES (crop estimation through resource and Environment Synthesis)-rice model incorporated in DSSAT version 4.5 was calibrated for genetic coefficients of rice cultivars by conducting field experiments during the kharif season at Jorhat, Kalyani, Ranchi and Bhagalpur, the results of which were used to estimate the gap in rice yield. The trend of potential yield was found to be positive and with a rate of change of 26, 36.9, 57.6 and 3.7 kg ha-1 year-1 at Jorhat, Kalyani, Ranchi and Bhagalpur districts respectively. Delayed sowing in these districts resulted in a decrease in rice yield to the tune of 35.3, 1.9, 48.6 and 17.1 kg ha-1 day-1 respectively. Finding reveals that DSSAT crop simulation model is an effective tool for decision support system. Estimation of yield gap based on the past crop data and subsequent adjustment of appropriate sowing window may help to obtain the potential yields.Keywords

Arsenic is a known poison of environmental and industrial origin. Prolonged exposure is associated with vascular diseases, skin lesions and cancer. The predominant form of arsenic in the nature is the pentavalent arsenate (AsV), which enters the body mainly via contaminated drinking water. The arsenic contaminated water samples were collected from different areas of Agra district and the arsenic concentration was estimated. Four groups of five albino rats each were administered 0.02 mg/litre arsenic present in drinking water for 7, 14 and 21 days respectively. After stipulated period the liver tissue was isolated for histopathological studies. The body weight, organ weight and their ratio decreased significantly (p<0.001). However, the SGOT, SGPT, ACP and ALP has shown an increase significantly (p<0.001) as compared to control groups. The histopathology of liver shows necrosis, appearance of vacuoles, nuclear degeneration changes after arsenic toxication. However, the alteration in enzymes and histopathological changes are dose dependent in the present investigation.Keywords

Arsenic may cause variation in tissues which affect histopathology of reproductive organs. The aim was to investigate the morphological and anatomical changes in structure of testis. In the present study, twenty male albino rats divided into four groups of five rats each. Distilled water and arsenic water were administrated orally to control and experimental groups for 7, 14, and 21 days respectively. The body weight, organ weight, sperm count, sperm motility and sperm sluggish motility were decreased significantly compared with control. The histopathological observations of testes after 7, 14 and 21 days of ground water arsenic treatment of rat showed some predominant change in the structure of testis. There are atrophic changes in testis due to degenerative changes in spermatogenic and leydig cells. The above results confirm the toxic effect of arsenic in testis of albino rats.Keywords

Dietary fibres (DF), composed of celluloses, hemicelluloses, pectins, lignins and other non-digestible materials in the food not amenable to the action of alimentary enzymes of human beings, play a multifaceted role in preventing a number of health disorders through their influence in the gastrointestinal tract. Their effectiveness is governed by physical properties such as particle size when ingested, water holding capacity, solubility and viscosity in aqueous phase, affinity to bile acid salts, cationic binding/exchange effect, fermentability in the bowel and chemical identity and proportion of the various constituents. DF undergo very little changes during processing of foods except size reduction.- Assessment of Environmental Contamination Potential of Distillery Effluent Using Plant and Animal Bioassays

Toxic effects of spent wash and crop field soil irrigated with it (hereafter referred to as distillery soil) were examined on 6 species of plants (2 cereals and 4 aquatic macrophytes) and 3 animals (cladoceran, fish and albino mice) by short-term bioassays using end point growth responses and mortality respectively. Seedling emergence was found nil (rice) to low (wheat = 30-40%) in distillery soil, but increased (48-00%) proportionately alongwith their vigor after mixing garden soil. In contrast to distillery soil, toxic effects of even cent percent soil leachate were nil on seed germination while meager (10- 15%) on seedling vigor in both the cereals. Spent wash, however, decreased germination and seedling vigor in both rice (germination = 5-100%; vigor = 2-100%) and wheat (germination = 0-64%; vigor = nil-93%) with an increase in its concentration, though vigor was greater (43%) than control in wheat at 10%. Among aquatic macrophytes, free-floating species (Lemna aequinoctialis and Spirodela polyrrhiza) were found to bemore sensitive than the submerged (Ceratophyllum demersum and Hydrilla verticillata) for spent wash; Lemna being the most sensitive species.
During a detailed study, sensitivity of different test organisms to spent wash (in terms of their EC/LC50 values) was in the order of: Daphnia (EC50 = 0.68%) > Gambusia affinis (LC50 = 1.31%) > Lemna (EC50 = 0.8-6.97%) indicating water flea to be the most sensitive test organism. The toxicity of soil leachate was, however, very low to these test organisms (Gambusia: LC50 = 12.1%; Lemna: EC50 = 46.5-278%) as also noted for cereals. The spent wash exposure not only decreased RBC counts (58-69%) in fish but also altered their morphology (77-97%).
Both food (7-14%) and water (27-45%) intake of albino mice (male) declined in soil leachate treatments (5-20%) alongwith their body (8-17%) and reproductive organ weights (4-63%), except that of prostrate gland weight increasing between 12% and 37%. The sperm counts (78-89%) and their motility (14-23%) also decreased in leachate treatments. Higher toxicity of spent wash may be ascribed to its greater conductivity (32.7mS), COD (54,900ppm) and chlorides (62,00ppm) than the soil leachate (EC = 3.56mS; COD = 2290ppm; chlorides = 220ppm).

The experiment was conducted during the Kharif season of 2012 and 2013 at demonstration field of Krishi Vigyan Kendra (KVK) at Porba village, Phek district, Nagaland to study the effect of integrated nutrient management on soil major nutrients of rajmash in acid soil of Nagaland. The experiment showed that the integrated treatments involving both organic and inorganic fertilizer influenced favourably the fertility status of the soil as compared to the control. Maximum increase in available N in soil (331.26 kg ha-1 in 2012 and 324.11 kg ha-1 in 2013) was found with T18 (5 ton FYM + biofertilizer + lime+ 100% NPK). Available P content of the soil showed significantly higher value in all treatments over the initial value. Among the treatments, the treatment receiving 5 ton FYM + biofertilizer + lime + 100% NPK in both the experimental year showed the highest P content of the soil. For available K too, maximum K content in the soil was recorded in the treatment T18 receiving 5 ton FYM + biofertilizer + lime + 100% NPK in both the years.Keywords

Recently, wireless sensor networks have attracted a lot of attention. Such environments may consist of many inexpensive nodes, each capable of collecting, storing, and processing environmental information and communicating with neighboring nodes through wireless links. In this paper, we survey a fundamental problem in wireless sensor networks, the coverage problem, which reflects how well an area is monitored or tracked by sensors. We first study several relevant computational geometric problems. Then, a number of papers aimed at solving the coverage problem in wireless sensor networks are discussed. We will address issues such as surveillance and exposure of sensor networks, coverage and connectivity in network deployment, and coverage and energy-preserving protocols for sensor networks.Keywords

Climate change is projected to alter the growing conditions of rice crop in different regions of India. Crop growth simulation model (DSSATv4.6) was calibrated and evaluated with four rice cultivars: PR 118 in Amritsar, Ludhiana; HKR 126 in Hisar and Ambala; Pant 4 in Kanpur and Sugandha-1126 in Modipuram on different sowing dates. The average yield of the selected optimum dates was 6391, 6531, 7751, 7561, 4347 and 4131 kg/ha for Amritsar, Ludhiana, Hisar, Ambala, Modipuram and Kanpur respectively. Both temperature and CO2 have increased. The combined effect of temperature and CO2 indicates decreased yield rate in the future decades. The present study shows that rice yield will decrease in the future and this may be due to increase in temperature. According to projection results, for all the locations average yield is higher in the decade 2010, except Amritsar in the decade 2030 and Ludhiana in the decade 2050. The average yield at Hisar, Ambala, Modipuram and Kanpur in 2010 was 7744, 7654, 4347 and 4021 kg/ha respectively. Amritsar and Ludhiana showed maximum average yield of 6880 and 6877 kg/ha respectively, in the decade 2030. Such yield reductions in rice crops due to climate change are mediated through reduction in crop duration, grain number and grain filling duration. These projections nevertheless provide a direction of likely change in crop productivity in future climate change scenarios.Keywords

Security is an essential part of wired and wireless network communication. Interestingly enough, these systems are designed to provide to open access across vast networked environments. Today's technologies are usually networkoperation- intrusive, i.e. they often limit connectivity and inhibit easier access to data and services. With the increasing popularity of wireless network, the security issue for end users could be even more serious then we expect. In wireless communication technology, a new networking technique, Ad-hoc wireless sensor network is currently under research. It has drawn much attention from researchers and user in recent years because it provides several application scopes for users and major challenges for researchers. Technical publications and conferences basically focusing on WSN technology and applications are commonplace. Research, development, and manufacturing of these networks are thriving. Many applications for WSNs have been proposed, but few are operational and many technical issues about WSNs remain to be solved by researchers. In this paper we present a summary on the security mechanisms issues and problems of current WSN technology. Of primary importance, the security issues facing WSNs are many and varied.Keywords

Image parsing is the problem of assigning an object label to each pixel. It unifies the image segmentation and object recognition problems. For instance, for a database of horse images, image parsing can be thought of as the task of classifying each pixel as part of a horse or nonhorse. In more complicated problems, image parsing might require multiple labels, e.g. roads, cars, houses etc. in outdoors scenes. Clearly, pixels can not be classified in this manner based only on their intensities or even local feature descriptors. Contextual information plays a critical role in resolving ambiguities. Image parsing can be posed as a supervised learning problem where a classifier is learnt from training data consisting of images and corresponding label maps. Autocontext and convolutional networks are two promising approaches that apply context to image parsing in the supervised learning setting.Keywords

Study conducted to know epidemiology and accomplish molecular characterization of Campylobacter isolated from meat of different species and human stool samples. A total of 759 samples, consisting of human stool (50) and meat of poultry (251), chevon (183), pork (127), fish (106) as well as carabeef (42) were processed, 50 samples showed characteristic colonies on mCCDA plates. All the 50 isolates were subjected to various biochemical tests and Latex agglutination test for confirmation of the genus Campylobacter. All the isolates were further analysed for molecular confirmation and PCR based genus specific amplification of 16S rRNA gene which yielded product of 816 bp in all the isolates. Multiplex PCR was performed for genus as well as species-level identification; all 50 isolates revealed 857 bp amplicon of 16S rRNA gene specific for genus Campylobacter. Thirty-five isolates exhibited 589 mapA gene amplicon specific for C. jejuni and 16 isolates gave 462 amplification product of ceuE gene specific for C. coli. Overall prevalence was 6.58%. The highest prevalence rate of 13.54% was recorded in poultry meat, followed by 7.6% in chevon, 0.78% in pork and 2% from human stool samples. None of the isolates were recovered from beef and fish meat samples. Most of the obtained isolates were classified as C. jejuni (35 strains, 70%), whereas C. coli was identified in 15 (30%) samples, indicating that the C. jejuni was the most commonly found species.

The CERES-wheat crop growth simulation model has been calibrated and evaluated for two wheat cultivars (PBW 343 and PBW 542) for three sowing dates (30 October, 15 November and 30 November) during 2008-09 and 2009-10 to study partitioning of leaf, stem and grains at Ludhiana, Punjab, India. The experimental data and simulated model data were analysed on partitioning of leaf, stem and grains, and validated. It was found that the model closely simulated the field data from phenological events and biomass. Simulated biological and grain yield was in accordance with-field experiment crop yield within the acceptable range. The correlation coefficient between field-experiment and simulated yield data and biomass data varied significantly from 0.81 and 0.96. The model showed overestimation from field-experimental yield for both cultivars. The cultivar PBW 343 gave higher yield than cultivar PBW 542 on 15 November during both years. The model performance was evaluated and it was found that CERES-wheat model could predict growth parameters like days to anthesis and maturity, biomass and yield with reasonably good accuracy (error less than 8%) and also correlation coefficient between field-experimental and simulated yield data and biomass data varied from 0.94 and 0.95. The results showed that the correlation coefficient between simulated and districts yield varied from 0.41 to 0.78 and also significantly at all six selected districts. The results may be used to improve and evaluate the current practices of crop management at different growth stages of the crop to achieve better production potential.Keywords

Nine parents and their eighteen hybrids from a line x tester design were evaluated for fruit yield and its components. Line x tester interaction was found significant for all the traits except, plant height considered variance due to treatment were found to be significant for all the characters under study. Whereas, variance due to lines was found to be a significant for all the characters except, days to 50% flowering and fruit length while variance due to testers was found nonsignificant for all the characters. On the basis of gca effects across three characters, RHRC-Cluster-Erect, PBC-535, LCA-235 and LCA-206 were identified as most promising parents for involving in hybridization programme aimed in improving number of fruit per plant as well as other important yield and yield contributing characters. Cross combinations, KA-2 x PantC-1, LCA-235 x Pusa Jwala, PBC-535 x PantC-1, RHRC-Cluster-Erect x Pusa Jwala, RHRC-Cluster-Erect x LCA-206 and RHRC-Cluster-Erect x PantC-1 were recorded specific combiner for fresh yield per plant due to positive significant of sca effect. The manifestation of heterobeltiosis for fruit yield per plant was evidenced by significant superiority of two out of eighteen crosses over better parent ranging from 6.87% in case of RHRC-Cluster-Erect x PantC- 1 to 13.48% in case of KA-2 x LCA-206 while rest of the crosses showed significant negative estimates of heterobeltiosis.The most promising crosses with significant positive heterobeltiosis for fresh yield per plant were KA-2 x LCA-206 (15.91%), PBC-535 x PantC-1 (20.10%), RHRC-Cluster-Erect x Pusa Jwala (16.32%), RHRC-Cluster-Erect x LCA-206 (42.60%) and LCA-438 x PantC-1 (16.26%).Keywords

The historic green revolution, which targeted at increasing crop yield, established India as one of the world’s biggest agricultural producer. Although India is an agricultural economy, farmers are not getting remunerative prices for their crops because of price fluctuation and market imperfections prevailed all over the country. Futures trading, as a tool for price discovery and risk management can pave the way for improving such market imperfections. The present study was conducted to examine the impact of futures trading on spot market of maize in India. The secondary data of maize spot and futures prices for the year 2005 to 2015 were collected from NCDEX. Johansen cointegration test was employed to access the relationship between futures and spot prices of maize. Further the direction of relationship was studied by using granger causality test and to investigate the long run causality and speed of price adjustment VECM was employed. The study found that spot and futures prices were independent and there was unidirectional causality between them. Further, results unveiled the long run causality from futures to spot market and it was the spot market which adjust itself to attain the long run equilibrium. The study concluded that futures are the market where framer can hedge their price risk and can explore the maximum possible profit from volatile prices. Therefore, policy measures should be adopted to bring the more agricultural crops under the network of futures trading.Keywords

Jatropha curcas (Euphorbiaceae) is a multipurpose shrub with varied medicinal uses and is of significant economic importance. In addition to being the source of biodiesel, its seeds are also considered highly nutritious and could be exploited as a rich and economical protein supplement in animal feeds. However, the inherent phytotoxins present in the seed is the hindrance. The toxicity nature of the seeds of the local variety of J. curcas is not known. Therefore, investigations were undertaken to evaluate the short-term oral toxicity of the seeds of locally grown J. curcas . Short-term toxicity was conducted in rats by daily feeding the basal diet (Group I), and the diet in which the crude protein requirement was supplemented at 25% (Group II) and 50% (Group III) levels through Jatropha seed powder. The adverse effects of Jatropha seed protein supplementation (JSPS) were evaluated by observing alterations in biochemical profiles. The biochemical profile of rats fed on diet with JSPS at both the levels revealed significant reduction in plasma glucose and total protein and increase in plasma creatinine, transaminases (Plasma glutamic pyruvic transaminase and Plasma glutamic oxaloacetic transaminase), and alkaline phosphatase.Keywords

Shielded metal arc (SMA) welding of 25mm thick wall 325mm O.D, 304LN austenitic stainless steel pipe has been carried out with GTAW ischolar_main pass by using conventional V-groove and narrow groove welding techniques at appropriately designed WPS to produce sound weld of significantly narrow weld groove. The characteristics of the narrow groove weld joints with respect to their weld size, microstructure, residual stresses, mechanical properties and corrosion susceptibility have been studied and compared to those of the conventional V-groove weld joints. It is observed that the use of narrow groove instead of conventional V-groove in welding of thick wall stainless steel pipe is beneficial especially with respect to reduction in grain coarsening at HAZ adjacent to the fusion line and lowering of residual stresses of weld joint by keeping the mechanical properties and susceptibility to IGC comparable to those of the V-groove weld joint. However the inclusion content of the narrow groove SMA weld has been found comparatively higher than that of the conventional V-groove weld.

Solid-to-water proportion decides the effectiveness of paste backfill in terms of transportation characteristics during mine backfilling. This article highlights various laboratory tests conducted to determine the optimum solid-to-water ratio. Also, numerical simulation was carried out using computational fluid dynamics technique (ANSYS FLUENT) to understand the slump lifting process and variation in volume of the paste with time. The optimum slump and spread for lead–zinc mill tailings paste were in the range 190– 200 mm and 330–340 mm respectively. The optimum water content in the paste fill for this study was found to be 23 wt%. Results show that the solid percentage is inversely related with slump and spread. Also, an optimum slump lifting speed needs to be maintained for accurate values of slump and spread.Keywords

Konkan Railway has many unstable slopes along the 741 km long route from Roha to Thokur in the states of Maharashtra, Goa and Karnataka in India. Frequent cases of boulder fall, slope failure and landslide used to occur on the track during the rainy season. Such cases have resulted in several severe train accidents, traffic interruptions, loss of lives and assets. Hence the Konkan Railway Corporation deployed several geotechnical measures such as wire-netting, retaining wall, rock bolting and shotcreting for stability enhancement. However, none of these measures proved effective and accidents continued. Finally, the Konkan Railway Corporation decided to redesign the cut-slopes using blasting. Excavation of hard rock for its removal without damaging the existing track (2– 3 m away from the slope) and disrupting the traffic, was a daunting task. An unplanned blast would have resulted in the closure of the route for hours. The present study explains the method in which entire cutting was redesigned by formation of 5 to 2 m wide berms at an interval of 6 m bench height from rail track level using novel direction controlled blasting technique. Further, stability of the cut-slope, before and after exacavation, has been determined using kinematic analysis and 3D numerical modelling. Similar technique can be adopted to widen or stabilize an active transportation route in hills.Keywords

Encountering hot zones while excavating tunnels for hydropower projects in the Himalaya, India, is a challenge for civil engineers. Blasting within the hot rock mass can pose serious threats due to possibility of temperature-induced unintended detonation of explosives. Moreover, the paucity of a suitable rock-blasting method for these hot zones sometimes compels engineers to realign the tunnel. Such a realignment is costly and time-consuming. A temperature of 50–98°C was encountered while excavating the rock mass for head race tunnel of Karchham–Wangtoo Hydro-Electric Project, Himachal Pradesh, India. The Directorate General of Mine Safety, India, suggests that blast-holes with temperature greater than 80°C must not be charged and blasted. Similarly, the use of electric or non-electric detonators is discouraged above 70°C because of premature detonation. Hence excavation works were suspended for tunnel construction. A unique drill and blast method has been adopted for blasting the hot strata in the tunnel. The technique described in this study can be easily followed in similar situations for tunnel-rock excavationKeywords

This paper describes effect of blast produced ground vibration on damage potential to residential structures to determine safe levels of ground vibration for the residential structures and other buildings in mining areas. Impacts of 341 blasts detonated at two mines were monitored at the test structures and 1871 blast vibrations signatures were recorded on or near the test structures. Cosmetic cracks in a native brick-mud-cement house were detected at peak particle velocities (PPV) between 51.6 and 56.3 mm/s. The reinforced concrete and cement mortar (RCC) structure experienced cosmetic cracks at PPV's of 68.6 to 71.3 mm/s at the first floor, whereas at second floor it was detected at PPV levels of 71.2 to 72.2 mm/s. Minor damage in brickmud- cement house was recorded at PPV levels of 81.0 to 89.7 mm/s. The RCC structure at first and second floors experienced minor damage at PPV levels of 104 mm/s and 98.3-118 mm/s respectively. The brick-mud-cement house experienced major damage at PPV level of 99.6 to 113.0 mm/s, while major damage was recorded in RCC structure on first floor at PPV of 122 mm/s, the second floor at PPV levels of 128.9-161 mm/s. Recommended threshold limits of vibrations for the different type of structures is based on these measurements and observations.References

In this study, two thermal springs are reported from the Demchok area in Ladakh, India. These are characterized by water having low total dissolved solids (TDS) content (~250 mg/l) as well as high pH (9.5) and surface temperature (75°C). Although these hot springs and their medicinal properties are known to locals, they have not been scientifically studied. Relatively low TDS despite high temperature could be due to sluggish ion-exchange processes in the geothermal reservoir. Such a situation might have developed because of the high water-to-rock ratio and/or smaller residence time of the geothermal fluid in the reaction zone.Keywords
