    The present investigation entitled “Studies on the biology and the predatory potential of Green lacewing, Chrysoperla carnea (Stephens) on different insect hosts” under laboratory condition was carried out during Nov. 2014 to March 2015 at Bio-control laboratory, Sardar Vallabhbhai Patel Uni. of Agri. and Tech., Meerut. During the study period the Green lacewing, Chrysoperla carnea adults were collected from the flowers of different crop plants in Meerut region. Isolated Chrysoperla carnea adults were identified on the basis of their external morphology. The Chrysoperla carnea completed their life cycle in 32-34 days. It was observed that the incubation, larval, pupal period and male, female longevity average 3.1, 8.8, 7.1 days and 26.2, 32.5 days, respectively. The feeding potential of Chrysoperla carnea larvae was observed under laboratory condition. The total food consumption of a single larva of Chrysoperla carnea were 419.32 ±11.75, 191.66 ±8.04, 166.66 ± 7.49, 155.99 ±7.26 and 143.66 ±6.96, eggs of C. cephalonica, nymph of A. craccivora, nymph of L. erysimi, nymph of M. hirsutus and nymph of D. mangifera, respectively. The fecundity of Chrysoperla carnea female was recorded on different flowers diet. The highest number of eggs was recorded 359.4 ±6.3, 274.46 ±6.38, 146.46 ±5.85, 126.26 ±6.02 and 109.26 ±5.47 eggs on the flowesr of Ricinus communis, followed by Brassica campestris, Hibiscus rosasinensis, artificial diet (honey+protein) and Cicer arietinum, respectively. The total 6 adult oviposition cages were maintained for the mass production of Chrysoperla carnea. A total of 24055 eggs were collected from one oviposition cage. The total cost estimated as sum of cost of rearing culture and initial purchase cost, which was Rs.768. As a result of this adopted technique approximately 24055 eggs per month were obtained, which was an additional output. The cost of egg production was observed Rs. 0.03/egg. In the result obtained that the eggs of Corcyra cephalonica, nymph of Aphis craccivora for larval food and the caster flower, mustard flower and artificial diet (honey+protein) for adults diet, respectively were found to be the most suitable host for the mass production of predator Green lacewing, Chrysoperla

    “Effect of balanced fertilizer and planting techniques on growth and yield of garlic (Allium sativum L.) Cv. G-282”.
    (Sardar Vallabhbhi Patel Universiy of Agriculture And Technology Meerut (U.P.), 2012) Kumar, Amit; Singh, Bijendera
    A field experiment was conducted at Horticultural Research Centre of Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut-250110,U.P. during Rabi 2010-11 & 2011-12 to study the “Effect of balanced fertilizer and planting techniques on growth and yield of garlic (Allium sativum L.) Cv. G-282”. The experiment consisted of three main plot treatments (Planting Techniques) (P1 -Narrow raised beds, P2 -Wide raised beds and P3 -Flat beds) and five sub plot treatments (Fertilizer levels F1-100% RDF N through inorganic, F2-100% RDF N through FYM, F3 -50% RDF N through FYM+50% RDF N through inorganic, F4 -25% RDF N through FYM+ 75% RDF N through inorganic and F5-Control (No fertilizer).The experiment was laid out in Split Plot Design with three replications. A significant increase in bulb yield with nutrient management involving organic manures and inorganic fertilizers over nutrient management through inorganic manures and nutrient management through organic fertilizers. The yield components such as number of cloves plant-1 and bulb weight were higher in balanced fertilizer as compared to organic nutrient management. Higher nitrogen, phosphorous and potassium uptake were observed in balanced fertilizer as compared to organic nutrient management and inorganic nutrient management.Morphological characters were lower in flat bed method of planting as compare to narrow raised beds method and wide raised beds method indicating that individual plant performance was better in wide raised beds method over flat bed method of planting. With respect to economics, highest gross returns and net returns was registered when garlic plants were nourished with 25% RDF N through FYM + 75 % RDF N through inorganic.

    Effect of Vermicompost scheduling on soil properties, growth performance of rice crop and its residual effect on wheat crop
    (Sardar Vallabhbhi Patel Universiy of Agriculture And Technology Meerut (U.P.), 2012) Kumar, Amit; Dhyani, B.P.; Kumar, A.;Singh,R.R.;Shahi,U.P.;Yadav,R.B.
    To study “Effect of Vermicompost Scheduling on Soil Properties, Growth Performance of Rice Crop and its Residual Effect on Wheat Crop”, field experiments were conducted during 2011-12 and 2012-13. The study area was CRC of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut. Soil of experimental site was low in organic carbon, available nitrogen, medium in available phosphorus and potassium with slightly alkaline pH. Ten different treatments comprising application of different levels of vermicompost alongwith with different levels of nitrogen and recommended level of PK were tested in a randomized block design with three replications. Rice variety PB-1 and wheat PBW-502 were grown during kharif and rabi seasons of both the years. Observations on different growth parameters, yield and yield attributing characters, nutrient content, nutrient assimilation and physico chemical properties of soil at different growth stages of rice-wheat cropping system were recorded. Data were subjected to statistical analysis on which basis treatments effect were explained. The results reveal that growth parameters and yield attributing characters of rice crop were higher with application of 100% NPK (T2) through chemical fertilizer followed by T3 where along with 75% N 100% PK basal application of 2 ton vermicompost was made. Grain yield was also higher in T2 but it did not differ significantly from T3, T4 and T5. Plant nutrient content and uptake was also higher in T2 at different growth stages of rice. The nutrients availability in soil was affected by the timing of vermicompost application. Organic carbon, pH and electrical conductivity of soil at different growth stages of rice remained unaffected due to application of different treatments. The residual effect of preceding rice crop treatments on number of tillers per meter row length of wheat, spike length and test weight was non significant while a significant residual effect was found on nutrients availability. The residual effect of 4 ton vermicompost application on grain yield of wheat was significant but application of 2 ton vermicompost could not result any significant effect. Percent organic carbon, soil pH, electrical conductivity remain unaffected due to residual effect while a significant effect was noticed on the bulk density of soil after wheat harvest. It is concluded that 25% nitrogen requirement of basmati rice can be supplemented through the application of 2 ton vermicompost ha-1 as basal, or at panicle initiation or at flowering stages of rice crop.
