ThesisItem Open Access Construction of Life-Tables for some Bi-Voltine crosses of mulberry silkworm (Bombyx mori Linnaeus) under lab condition(Sardar Vallabhbhi Patel Universiy of Agriculture And Technology Meerut (U.P.), 2013) Kumar, Pramod; Hem Singh; Ramesh Singh, D.V. Singh,S.K.SachanThe commercial production of silk is called as “Sericulture” Which is a labour intensive, agro-based cottage industry, ideally suited not only to India but to all developing country of tropical belt. Mulberry Silk worm (Bombyx mori. L) is an monophagous and multivoltine insect without diapauses. The Present study entitled “Construction of Life-Tables for some Bi-Voltine crosses of mulberry silkworm (Bombyx mori Linnaeus) under lab condition” was carried out on Sericulture Research, Demonstration and Training Unit lab, Department of Entomology, College of Agriculture, S. V. P. University of Agriculture and Technology Modipuram, Meerut (U.P.) during 2011-12. . Investigations were undertaken to record the (i) Construction of age specific life table. (ii) Construction of stage specific life table (iii) Construction of life and fertility table for female. The age specific life table revealed that the age specific survivorship on the two hybrid cross of mulberry silkworm viz, NB4D2×SH6 and KC2×FC1. The Bombyx mori L. hybrid cross NB4D2×SH6 took the shortest time 37 days to completes its generation while hybrid cross KC2×FC1 required the maximum, 43 days. The apparent highest mortality rate was recorded on NB4D2×SH6 (14%) and the lowest (11%) on KC2×FC1 at room temperature and the potential fecundity. Was recorded 333 on NB4D2×SH6 and the lowest 314 on KC2×FC1 at control temperature. Based on the results obtained from the present study, it may be concluded that among the hybrids cross of mulberry silkworm NB4D2×SH6 was the most economic hybrid cross of mulberry silkworm for the sericulture growers.ThesisItem Open Access Determination of WUE and growth stage specific crop coefficients (Kc) of wheat using weighing Lysimeter in present climate scenario in Madhya Pradesh(RVSKVV, Gwalior (M.P.), 2021) Kumar, Pramod; Sharma, Dr. AmitaThesisItem Open Access Development and validation of physiological strain index for evaluating heat stress in cattle and buffaloes.(NDRI, Karnal, 2008) Kumar, Pramod; Upadhyay, R CThesisItem Open Access Effect of Melatonin Implant on Productive and Reproductive Performance of Murrah Buffaloes (Bubalus Bubalis) During Summer Season.(NDRI, Karnal, 2017) Kumar, Pramod; Singh, Sohan VirThesisItem Open Access Effectiveness and residue dynamics of some synthetic pyrethroids against Helicoverpa armigera Hub.

Wheat being a winter season crop is often exposed to a short period of heat stress during anthesis and grain filling. Heat stress after anthesis induces leaf senescence and forced maturity results in poor yield. Delaying in leaf senescence after anthesis, is referred as stay-green trait, that maintains photosynthetic activity for a longer period and thus provides higher yield. Therefore, the maintenance of the stay-green trait has prime importance. An alternative approach for maintaining stay green is hormone therapy. Stay green traits have been attributed to higher cytokinin levels and or reduced ethylene production. Therefore, in order to study the hormonal regulation of stay-green trait under heat stress in wheat, the present thesis work was carried out by conducting two experiments. During the first experiment, 32 diverse wheat genotypes were screened for the stay-green trait under dark stress conditions in the lab and two contrasting genotypes were selected for subsequent experiment II. Experiment II was conducted using two contrasting genotypes namely Chirya 3 (stay green type) and HD 2329 (non- stay green type). This experiment comprised of two main treatments i.e. normal sown condition (18 Nov 2020) and late sown (18 Jan 2021) heat stress condition and five sub- treatments for hormonal manipulation i.e. Control (Water spray), Lovastatin (Lova) (an inhibitor of cytokinin), Benzyl aminopurine (BAP), Thidiazouron (TDZ) and Cobalt chloride (CoCl2) (an inhibitor of ethylene) at anthesis stage to alter the endogenous level of phytohormones. Results of this study revealed the reduction in SPAD value, NDVI, leaf area, MSI, RWC, CTD, photosynthetic pigments, PN, gs, TR, dry matter partitioning, Fv/Fm ratio, YII, yield and its attributes, and enhancement in senescence score, NPQ, lipid peroxidation, H2O2, total soluble sugar, proline content, antioxidant enzymes activity, chlorophyllase enzyme activity under late sown heat stress condition. In general, foliar application of BAP, TDZ, and CoCl2 enhanced SPAD value, NDVI, leaf area, MSI, RWC, CTD, photosynthetic pigments, PN, gs, TR, Fv/Fm ratio, YII, NPQ, total soluble sugar, proline content, dry matter partitioning to ear, yield and its attributes, heat tolerance index and restricted lipid peroxidation, H2O2, chlorophyllase activity, heat susceptibility index while the contrasting results were obtained with the application of lovastatin. From the present study, it may be concluded that application of BAP, TDZ, and CoCl2 enhanced stay-green trait, heat tolerance, and yield by increasing photosynthetic pigments, PN, gs, TR, partitioning, Fv/Fm, NPQ, YII, osmolytes, MSI, CTD, RWC, antioxidant enzymes activity, leaf area and by decreasing ROS production, Chl degradation, lipid peroxidation, and CHLase activity. Further, lovastatin treatment confirmed the role of cytokinins in the stay-green trait.ThesisItem Open Access Impact of milk proteins and fat in controlling fat bloom formation in dark chocolate.(NDRI, Karnal, 2017) Kumar, Pramod; Seth, RamanThesisItem Open Access IMPACT OF PLANT GROWTH REGULATORS ON GROWTH AND FLOWERING OF GLADIOLUS (Gladiolus grandiflorus L.) CV. CANDYMAN UNDER CHHATTISGARH PLAINS(Indira Gandhi Krishi Vishwavidyalaya, Raipur, 2016) Kumar, Pramod; Verma, L.S.; Sharma, Gaurav; Kuruwanshi, V.B.; Saxena, R.R.The present investigation entitled “Impact of plant growth regulators on growth and flowering of gladiolus (Gladiolus grandiflorus L.) cv Candyman under Chhattisgarh plains condition.” Was conducted in Rabi season during 2015-16 at Research cum Instruction Farm, Department of Horticulture, Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.). The experiment comprised of three growth regulators with three concentration viz., NAA (25 ppm, 50 ppm and 100 ppm) GA3, (200 ppm, 250 ppm and 300 ppm) and CCC (150 ppm, 200 ppm and 250 ppm). Each growth regulator at three concentrations in addition to distilled water spray as control comprised ten treatments of this experiment. The experiment was laid out in a Randomized Block Design (RBD) with three replications. The data were analyzed to work out the effect of plant growth regulators on morpho-physiological traits viz., plant height, number of leaves per plant, length of leaves, number of days taken to first spike emergence, length of spike, length of rachis, internodal length of floret, number of days taken to first floret open/bloom, number of florets per spike, vase life, number of spike per square meter and yield traits (number of corm per plant, diameter of corm, weight of corm per plant, number of cormel per plant, and weight of cormel per plant) of gladiolus. Application of GA3 @ 200 ppm foliar spray at 40 days after planting was found more effective for better performance of different attributes namely, plant height, number of leaves, length of leaves, first spike emergence, first floret open / bloom, spike length, rachis length, number of floret, internodal length, diameter of flower, number of spike per meter square, vase life of cut spike (days) and diameter of corm. Whereas, CCC @ 200 ppm foliar spray at 40 days after planting was found best for maximum number of corms per plant, number of cormels, weight of corms and weight of cormels.ThesisItem Open Access An Investigation on Genetical Architecture And Adaptability in Maze (Zea mays L.)(MPUT, UDAIPUR, 1994-11-17) Kumar, Pramod; Gupta, S.C.ThesisItem Open Access ThesisItem Open Access ThesisItem Open Access New insight in preservation of in- situ caprine cauda epididymal spermatozoa at -20 IlC :plausible implications for the conservation of biodiversity(Kolkata, 2009) Kumar, Pramod; Dutta, Dr. U.; Ahamed, Prof. K.; Basu, Prof. S.; Nandi, Dr. P.

The experimental field was uniform and leveled, sandy loam in texture, low in available nitrogen (219.3 kg ha-1), medium in available phosphorus (16.9 kg ha-1), potassium (244.3 kg ha-1), sulphur (14.3 kg ha-1), zinc (0.78 mg kg-1) and iron (9.42 mg kg-1) with slightly alkaline in reaction (pH 7.82). The experiment was carried out in Randomized Block Design with four replications and 10 treatments. The treatments comprised of T1 (control), T2 RDF (-S), T3 RDF (+S), T4 125% RDF (+S), T5 100% RDF (-S) + 4 ton FYM, T6 100% RDF (-S) + 1.25 ton Vermicompost, T7 100% RDF (-S) + 2 ton FYM + 0.6 ton Vermicompost, T8 75% RDF (-S) + 4 ton FYM, T9 75% RDF + 1.25 ton Vermicompost and T10 75% RDF + 2 ton FYM + 0.6 ton Vermicompost. Treatments effects of nutrient management were evaluated in terms of growth and yield of mustard. The results also revealed that among the different integrated nutrient management treatments the highest grain yield (24.3 & 25.7 q ha-1) was obtained under 100% RDF (-S) + 2 ton FYM + 0.6 ton Vermicompost which were at par (23.7 & 24.4 q ha-1) with the application of 75% RDF + 2 ton FYM + 0.6 ton Vermicompost and (22.8 & 23.0 q ha-1) 100% RDF (-S) + 1.25 ton Vermicompost during both the years. The highest total NPK, S, zinc and iron content and uptake by grain and straw found with 100% RDF (-S) + 2 ton FYM + 0.6 ton Vermicompost was at par with 75% RDF + 2 ton FYM + 0.6 ton Vermicompost and 100% RDF (-S) + 1.25 ton Vermicompost. The results revealed that the highest net monetary return (₹ 98935 & 115085 ha-1) and B: C ratio (3.47 & 3.88) was obtained with 100% RDF (-S) + 2 ton FYM + 0.6 ton Vermicompost, which was found at par with 75% RDF + 2 ton FYM + 0.6 ton Vermicompost during both the years. On the basis of two year experiment it can be concluded that application of 75% RDF + 2-ton FYM + 0.6 ton Vermicompost may be recommended for achieving higher yield and net return from mustard crop and maintaining soil sustainability.ThesisItem Open Access Performance of wheat [Triticum aestivum (L.) emend. Fiori & Paol] varieties under varying sowing and input management systems(MPUAT, Udaipur, 2007) Kumar, Pramod; Singh, S. M.ABSTRACT In order to evolve low cost, resource efficient production technology for wheat, a field experiment entitled “Performance of wheat [Triticum aestivum (L.) emend. Fiori & Paol] varieties under varying sowing and input management systems” was conducted on clay loam soils having medium in available N, P and high in K status (259.50, 23.30 and 383.05 kg available N, P and K ha-1, respectively), EC 0.79 dSm-1 and pH 8.17 at the Instructional Farm, Department of Agronomy, Rajasthan College of Agriculture, Udaipur during the rabi season of the year 2002 -03 and 2003-04. The objectives were to evaluate performance of newly recommended wheat variety GW 322 compared to existing popular variety Lok-1 and to assess agronomic feasibility of furrow irrigated raised bed (FIRB) sowing system for sole wheat and wheat intercropped with forage crops (berseem / Chinese cabbage) compared to conventional one and to explore possibilities for reducing inputs (seed and fertilizers). The treatments consisted combinations of 2 wheat varieties (GW 322 and Lok-1), 4 sowing systems i.e., conventional (rows at 22.5 cm apart), FIRB sole wheat (two rows of wheat on each bed at a distance of 70 cm), FIRB + berseem (simultaneous sowing of wheat on beds and berseem in furrows), FIRB + Chinese cabbage (simultaneous sowing of wheat on beds and Chinese cabbage in furrows) and 4 input levels i.e., 100% recommended seed + 100% recommended fertilizer, 75% recommended seed + 75% recommended fertilizer, 100% recommended seed + 75% recommended fertilizer and 75% recommended seed + 100% recommended fertilizer. These 32 treatment combinations were evaluated under split plot design allocating combination of varieties and sowing system in main plots and input levels in sub plots with 3 replications. The results showed that variety GW 322 produced significantly higher tillers m-2 and had higher nitrogen status in plant parts as well as accumulated maximum quantum of biomass m-2 at each stage and at harvest. This manifested in production of higher effective tillers m-2 and improvement in yield attributes (weight of single ear, grain weight ear-1, grains ear-1 and grain m-2) with concomitant increase in crop productivity in terms of grain and biological yield by 10.1 and 11.6 per cent over Lok-1. This variety also showed superiority in grain protein content. Besides these, growing of GW 322 gave additional net returns of Rs 3939 ha-1 over Lok-1 and increased B:C ratio from 3.53 to 3.83. Among sowing system, conventional sowing significantly enhanced overall growth of the crop in terms of total tillers m-2 and biomass accumulation at successive growth stages compared to FIRB planted sole wheat as well as intercropped with forage crops. These improvements reflected in realization of increased grain, straw and biological yields by 14.3, 19.3, 27.5; 15.5, 18.9, 21.8 and 15.0, 19.0, 27.6 per cent over FIRB (W), FIRB (W+B) and FIRB (W+CC), respectively. On wheat equivalent yield basis, FIRB (W+B) proved most economically viable sowing system as it produced highest WEY (74.53 q ha-1) and fetched significantly highest returns (Rs 46809 ha-1) representing monetary gain of Rs 3533, Rs 11252 and Rs 17400 ha-1 over FIRB (W+CC), conventional and FIRB (W) systems. Among input levels, 100% RSR + 75% RDF and 75% RSR + 75% RDF significantly reduced total dry matter by 5.1 and 10.0 per cent over 100% RSR + 100% RDF. However, reduction in seed rate did not bring any significant reduction in dry matter accumulation. The reduction in input levels i.e., 75% RSR + 75% RDF and 100% RSR + 75% RDF significantly reduced the crop yields. The extent of reductions were by 9.0, 9.4, 9.2 and 6.4, 6.0, 6.2 per cent in grain, straw and biological yield ha-1. While reduction in seed rate had least adverse effect on crop productivity. The crop raised with reduced inputs of aforesaid level (75% RSR + 75% RDF) accumulated least nutrients at successive stages and at harvest. Compared to highest overall productivity (64.16 q WEY ha-1), profitability (Rs 40818 ha-1) and B:C (3.75) with use of 100% RSR and fertilizers + 100% RDF, reduced input levels of 75% RSR + 75% RDF and 100% RSR + 75% RDF reduced it by 5.36, 4.94, q ha-1; Rs 3909, 3623 ha-1 and 0.13, 0.15, respectively. While reduction in seed rate by 25 per cent under input levels of 75% RSR + 100% RDF had least effect.ThesisItem Open Access RESIDUE TOXICOLOGY OF SOME NEW INSECTICIDES TO THE APHID, Lipaphis erysimi Kalt AND FORAGING HONEYBEE, Aphis melliifera L.
