The May-June beetle, Anomala blanchardi Blanch is one of the major pests of primary tasar food plants, Terminalia arjuna Bedd. and T. tomentosa W & A causing 10-15% loss to the foliage with an average incidence of 15-20 adults per bush. An experiment was undertaken to evaluate the effect of Amrutguard a Neem (Azadirachta indica A. juss) formulation on mortality and feeding inhibition efficacy against adults of A. blanchardi. Observations reveal that maximum mortality (77.77%) was recorded when adults of A. blanchardi were fed with 30 ppm Azadirachtin treated leaves as compared to control (6.66%). Results indicate that in the said concentration the excretion oflitter was minimum (0.39 g/treatment) vis-a-vis control (1.527 gl treatment). This reflects the minimum feeding due to strong antifeedant properties of Azadirachtin. The paper deals with the use of non-wood products of neem in the pest management thereby minimizing crop loss and load of insecticides in the forest ecosystem.- IPM Approach for the Control of Major Defoliators of Primary Tasar Food Plants

Defoliators Anomala blanchardi Blanch, Tricliona picea Jacoby, T. variabilis Jac., Myllocerus viridanus Fab. and Notolophus antiqua Linn. are the major pests of primary tasar food plants, namely, Terminalia arjuna Bedd and T. tomentosa W&A causing 15-20% foliage unsuitable for silkworm feeding. The soil application of neem cake (60 kg/acre) and foliar spray of Azadirachtin (6.0 ppm) were found effective in suppressing growth and development of coleopteran grubs and lepidopteran larvae respectively. Based upon these finding, various control measures such as cultural (deep digging of soil), mechanical (collection and destruction of different developmental stages), soil application of neem cake, foliar application of Azadirachtin and combination of these four control measures (IPM) were taken up for evaluation of their efficacy. The averages of leaf yield per plant, leaf damage per cent and number of grubs per cubic feet for each treatment were recorded. Results reveal that IPM was effective (leaf yield/plant-4.266 kg, leaf damage - 11.25% and number of grubs/cft - 0.125) as compared to control (leaf yield/plant - 2.468 kg, leaf damage - 40% and number of grubs/cft. - 1.750) in controlling the defoliators. The foliage damage could be reduced by 71-87% over control by adopting IPM. The safe period for Azadirachtin was found to be 5 days for tasar silkworm, Antheraea mylitta D.- Reactivation of Dormant Lenticels by Exogenous Application of STIK and GA3

Tbe cuttings of Holoptelea integrifolia and Pyrus pashia trees receiving STIK as well as GA3 at 0.1,0.2,0.5, 1.0 and 2.0 mgmt-1 levels showed that the stimulalion of lenlicels is more or less paralleled in the two taxa. The higher concentrations of STIK proved more effective in inducing new lenticels, whereas GA3 showed a pronounced influence at lower concentrations.- Common Male Sexual Disorders and Their Treatment by Indigenous Drugs

A field experiment was carried out using twenty genotypes of cowpea [Vigna unguiculata (L.) walp] at Rajasthan College of Agriculture, Udaipur during 2008-09 treated with two Bradyrhizobium strains. Association studies revealed that seed yield per plant showed significant positive co-rrelation with pods per plant in all the environments, biological yield (E1 and E2), harvest index (E1 and E3), protein content (E3), days to maturity, nodule fresh weight and nitrogen content in (E3), most of these characters were also mutually correlated. Path analysis studies for seed yield revealed direct and indirect contribution of biological yield, harvest index, branches per plant, plant height and number of nodules (E1), pods per plant, nodule fresh weight, protein content and nodule dry weight (E2), nodule dry weight, branches per plant, protein content and plant height (E3). While the protein content revealed direct as well as indirect contribution of biological yield, number of nodules, harvest index, 100 seed weight and nodule fresh weight (E1), number of nodules, seed yield per plant, leghaemoglobin content and nitrogen content in (E2), seed yield per plant, harvest index, number of nodules and nodule fresh weight in (E3).Keywords

The present investigation consisted of 45 hybrids alongwith 18 parents and four checks viz., Arawali Makka-1, Mahi Kanchan, Navjot and PEHM-2 a total 67 entries was conduted during Kharif 2002 in Randomised Block Design having three replications. The data were recorded on fourteen traits to study general and specific combining ability effects. In general inbred lines L1, L3, L11 and L15 were considered good general combiner for yield and yield contributing traits as well as for quality traits. Among the testers, the tester T2 was considered good general combiner for maturity traits, plant type traits, harvest index and starch content. Majority of the hybrids exhibited significant positive values for yield and yield contributing traits as well as quality traits. Thereby, indicating that for these traits the genes with positive effects were dominent. The variance due to lines was of greater magnitude than that of testers for most of the traits. The ratio of 62sca/62gca indicated prependerance of non-additive variance for most of the traits. Parental lines L1, L3, L11 and L15 were found to be good general combiners for grain yield per plant as well as for other traits. Hybrid L12x T1 exhibited maximum significant positive sca effects for grain yield per plant. While the hybrid L2 x T1 exhibited highest estimates of significant positive sca effects for starch content. In general, there is a close association between sca effects, relative heterosis and per se performance for grain yield per plant was observed among the best hybrid identified on the basis of sca effects.Keywords

Coal combustion in thermal power plants contributes to more than 70% of the e1ectricity generated in India. Combustion of coal generates huge amounts of wastes which are disposed off in nearby ponds. The ash generated from the coal combustion process contains a lot of toxic elements which are leached out by the percolating rain water and subsurface runoff from the ash ponds. These toxics cause sufficient amount of groundwater contamination.
DC resistivity studies are very helpful in determining the subsurface lithology and in delineating the zones of groundwater contamination. The present study was conducted in and around the ash disposal sites of Kolaghat Thermal Power Plant in West Bengal. Six Schlumberger soundings were conducted in the four ash ponds of the thermal power plant. The quantitative interpretation of the VES curves has been done by a very fast simulated annealing computer program developed for this purpose. The subsurface lithology as determined from the VES curves shows alternate layers of clay and sand upto a depth of 6Om. All the sounding locations show a general thin top layer of ash of high resistivity mixed with coarse sand or clay followed by a 29-50m thick layer of wet clay of very low resistivity. The lowermost layer is sandy clay to clayey sand in all the cases. Groundwater samples have also been collected from the tube wells located near the ash ponds and analysed for pH, TDS and trace elements. Results of the chemical analysis show high values of TDS and high concentration of the toxics. Earlier studies on the geochemistry of the pond ash have shown that the ashes are characterized by hlgh concentration of As, Pb, Cu, Ni, Fe, Zn, Cr, CO, Mn all of which exceed the crustal abundance by a factor of 3-5. The high concentration of the toxics (As, Al, Li, As, Zn, Ag, Sb, Si, Mo, Ba, Rb, Se, Pb) in the water samples implies significant input from the ash pile due to leaching. This increases the TDS values of the water. The low resistivity values of the intermediate clayey layer along with the high values of TDS and high concentration of the toxics imply that the contaminant zone lies at a shallow depth of 29-50m thick. It is formed due to leaching of the toxics from the top sandy layer and adsorption in the clayey layer.Keywords

This paper presents an analysis of impact of international trade an the shares of various factors for growth of production and employment in the Indian economy. The period of study is from the financial year 1979-80 to 1996-97. This period has witnessed significant changes in the policy framework regarding international trade in India. While prior to the year 1984-85. the policy of Import Substitution (IS) was followed in India, gradual transition to Export Promotion (EP) led policy was undertaken from 1984-85 onwards. It later prepared ground for further liberalisation of industrial and foreign trade policies during 1991-92.- A Novel Solution Methodology for the Optimization of Thermal Analysis in the Solar Parabolic Trough Collector
