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

Pot experiment on growth and quality parameters of strawberry was conducted at Narendra Deva University of Agriculture and Technology, Narendra Nagar (Kumarganj), Faizabad, U.P., India to evaluate the effect organic manure (Farm Yard Manure, vermicompost and press mud) and biofertilizers (Azotobacter, phosphate solubilizing bacteria and Azospirillum). Each treatment combination has shown significant effects on most of the parameters, but the combination of vermicompost and PSB showed highest plant height (23.59 cm), leaves plant-1 (12.67), primary branches plant-1 (10.50), secondary branches plant-1 (27.35), first flowering (61.06 days), flowers plant-1 (15.33), first fruit setting (72.80 days) and fruits plant-1 (8.33). Similarly, the treatments combination of vermicompost and PSB significantly affected the Total Soluble Solids (TSS) (10.75° Brix), titrable acidity (0.82), vitamin C (57.24 mg/100gm fruit), total sugars (5.95 %) and juice content (79.50 %).Keywords

The aim of this investigation was to know daily changes (circadian) in the blood plasma free (unconjugated) testosterone (TF) and estradiol-17β(E2F) and its conjugated testosterone glucuronide (TG) and testosterone sulfate (TS) as well as estradiol-17β glucuronide (E2G) and estradiol-17β sulfate (E2S) sex steroids in a mature female fish Cirrhinus mrigala (Ham.) during spawning phase using enzyme-linked immunosorbent assay (ELISA) method. The two sex steroids testosterone and estradiol-17β exhibited identical circadian rhythm: a major peak 29.02±3.58 ng/ml occurred at the onset of the dark phase and a minor peak 12.79±1.89 ng/ml was generally observed 4 hour after the onset of light phase . The TG peak (9.23±1.04 ng/ml was in the dark phase whereas TS during 12.00 PM of dark phase. The E2G 7.19±.76 ng/ml peak was also indicated high during 04.00 am of the dark phase. Result indicated that during the dark phase elevation of free and conjugated sex steroids have important role for spawning, and maintaining the equilibrium of free and conjugated steroids.Keywords

The objectives of the present investigation was to monitor the HCHs (isomers of hexachlorocyclohexane), DDTs (metabolites of dichlorodiphenyltrichloroethane), chlorpyrifos in tissue bioaccumulation and plasma levels of cortisol between the sampling sites of the unpolluted ponds of Gujartal, Jaunpur (reference site) and the polluted rivers the Gomti (Jaunpur) and the Ganga (Varanasi) as stress hormone of some edible catfishes during non-breeding season owing to industrialization. The insecticides were measured by the gas liquid chromatography (GLC) and plasma cortisol by Enzyme-Linked Immunosorbents Assay (ELISA). The results indicated that the presence of HCHs, DDTs and chlorpyrifos was much higher in the catfishes captured from the river Gomti than those of the river Ganga when compared to reference site. The plasma level of cortisol was low in the fishes captured from both the rivers. In conclusion, the fishes from polluted rivers showed high degree of contamination which caused stress and ultimately decreased the growth of edible fishes of riverine sources.Keywords

Mass is the only base unit, which is represented as a primary standard in the form of artifact for more than 125 years. International prototype of kilogram (IPK) is kept at the Bureau International des Poids et Mesures (BIPM), Paris and serves as the international standard of kilogram. It is made of 90% platinum and 10% iridium and as a cylinder of 39 mm diameter and 39 mm height. Replicas of the IPK are made of the same material and used at BIPM as reference or working standards and national prototype of kilogram (NPK), kept at different National Metrology Institutes (NMIs). NPK-57, kept at CSIR-National Physical Laboratory, is sent periodically to BIPM for calibration.References

The Alternaria blight is one of the most destructive fungal disease of Indian mustard causes severe damage to the crop. Ten isolates of A. brassicae were collected from various agro-climatic location of India viz., Uttar Pradesh (Ab1), Madhya Pradesh (Ab2), Uttarakhand (Ab3), Bihar (Ab4), Jharkhand (Ab5), West Bengal (Ab6), Haryana (Ab7), Rajasthan (Ab8), Chhattisgarh (Ab9) and Gujarat (Ab10) and characterized for pathogenic and molecular variations. All the isolates showed high level of variability. The incubation period of the isolates was recorded on B. juncea 3 to 4 days, B. carinata 6.17 to 6.83 days, B. napus 5.17 to 6.00 days, B. nigra 4.17 to 5.17 days and in B. campestris it was ranged from 3.17 to 4.00 days. The results revealed that the maximum PDI was noted on Brassica juncea followed by B. campestris var yellow sarson, B. nigra, B. napus and B. carinata. Based on PDI ten isolates could be classified into three groups in which group one consist of isolates Ab3, Ab6, Ab7 and Ab5. Isolates Ab8, Ab2 and Ab4 fall in second group; while group three include isolates Ab1, Ab9 and Ab10. The dendrogram analysis identified two major clusters with 82 per cent similarity. One cluster (group I) comprised of 3 isolates (Ab1, Ab10 and Ab2). Whereas, another cluster (group II) comprised of Ab3, Ab6, Ab7, Ab5, Ab4, Ab8 and Ab9 at 86 per cent similarity. The three isolates (Ab3, Ab6 and Ab7) of group II showed 100 per cent similarity based on molecular basis.Keywords

Pollination in cucumber (Cucumis sativus L.) was studied using stingless bees, Tetragonula iridipennis Smith and honey bee, Apis cerana F. Data on the resource partitioning revealed the foraging activity of pollinators. Pollination efficiency index was observed to be maximum with A. cerana (24) followed by T. iridipennis (14), and significantly maximum fruit set (81.66 and 78.97%) was obtained with their pollination. An increase of 87.48% in fruit set, 46.47% in healthy fruits and 275.23% in seed numbers was noticed, with longer (17.85 and 17.22 cm) and heavier (0.415 and 0.411 kg) fruits in the A. cerana and T. iridipennis pollinated plots. Maximum number of healthy fruits was achieved with bee pollination as compared to open pollination and control, and A. cerana showed more mortality as compared to T. iridipennis.Keywords

Impact of bee pollination on brinjal (Solanum melongena L.) under protected condition was assessed with five pollination treatments viz., Apis mellifera L., Apis cerana F., Tetragonula iridipennis S., open pollination and control (pollinator exclusion). Comparative foraging activity and pollination efficiency index of the pollinators was recorded along with fruit production and quality parameters (fruit yield, length, diameter and weight, seed number and weight). Data revealed maximum pollination efficiency index (21) for A. cerana. The weight of fruit (96.30 g), diameter (56.54 cm), healthy fruits (53.89 %) observed with A. cerana was maximum. However, fruit length (15.10 cm), fruit yield (48.33 %) and seed weight (5.79 g) were found at par in all the pollination treatments. Significantly least crooked fruits (13.73%) were obtained when A. cerana was used, along with many folds increase in fruit set (26.69 %) and quality.Keywords
