ThesisItem Open Access Bioethanol production from waste corn using Saccharomyces cerevisiae and Aspergillus awamori(Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur, 2019) Kumar, Ashish; Rajput, L.P.S.ThesisItem Open Access “Characterization of genetic variability in Hill lemon (Citrus pseudolimon Tanaka) strains of Kangra district of Himachal Pradesh”(College of Horticulture and Forestry Neri, Hamirpur (H.P.), 2021-12-04) Kumar, Ashish; Kaler, Rajesh KumarThe present investigation entitled, “Characterization of genetic variability in Hill Lemon (Citrus pseudolimon Tanaka) strains of Kangra district of Himachal Pradesh” were undertaken at Regional Horticultural Research and Training Station RHRTS, Jachh during 2019 and 2020 to assess the extent of genetic variability, heritability and genetic advance, correlation coefficient and path coefficient analysis. The material for present study consisted of 31 local strains/genotypes from 5 different growing areas of district Kangra (Nurpur, Fatehpur, Indora, Jawali, Dehra). Significant variations were observed for the tree shape, growth habit, spine shape, canopy spread, spine length, leaf shape, types of margins, leaf apex, leaf length and width, ratio of leaf length and width, leaf area, fruit weight, fruit length and width, fruit shape, fruit colour, fruit surface texture, number of segments/fruit, epicarp thickness, oil gland density, yield/ plant, juice content, number of seeds, seed weight, among the 31 genotypes. The maximum TSS was observed in genotypes G2, G14, G19 and G30 i.e., 8.03°B and the minimum TSS was observed in genotype G16 (6.65°B). The ascorbic acid content was maximum in G23 (36.43 mg/100 ml) and it was minimum in genotype G26 (21.89 mg/100 ml). The maximum significant titratable acidity was observed in genotype G12 (7.70 %) and the minimum significant titratable acidity was found in genotype G20 (5.11 %). The highest (2.35) pH was observed in genotypes G10 and G17 and the lowest (2.21) pH was observed in genotype G4. The average fruit weight was highly correlated at genotypic level and phenotypic level with fruit length (0.955) and (0.873), fruit width (0.931) and (0.831), number of seeds (0.954 and 0.881), seed weight (0.942) and (0.870), juice content (0.991) and (0.963) and juice percentage (0.929) and (0.693). The path analysis revealed that the maximum positive and direct effect of average fruit weight was observed in juice content (0.962) followed by seed weight (0.952) and leaf length (0.490) while the maximum negative and direct effect on average fruit weight was observed in number of seeds per fruit (-0.642). The phenotypic and genotypic coefficient of variability was high for spine length (38.38 % and 37.17 %), leaf area (31.98 % and 26.93 %), number of seeds (29.75 % and 26.13 %) and seed weight (23.81 % and 20.91 %). High heritability estimates were observed in spine length (93.79 %), juice content (81.95 %), oil gland density (84.26 %), TSS (92.13 %) and titratable acidity (96.02 %) while low heritability values were observed in leaf ratio (22.21 %) and pH (22.76 %). The genetic gain was observed higher in spine length (74.16 per cent of mean), leaf area (46.73 per cent of mean) and number of seeds (47.28 per cent of mean). The lowest Citrus psylla incidence was observed in G1 followed by G4 and the maximum incidence was observed in G12. The maximum incidence of Citrus leaf miner was observed G3 and the minimum incidence was observed in G24 and G21. The maximum incidence of Citrus canker was observed in genotype G8 and the minimum incidence was observed in genotypes G16 and G3ThesisItem Open Access COMPARATIVE PERFORMANCE OF ORGANIC AND INORGANIC FARMING PRACTICES ON PRODUCTIVITY OF DIFFERENT CROPPING SYSTEMS(CSKHPKV, Palampur, 2017) Kumar, Ashish; Saini, J.P.The experiment was laid out in split plot design with three farming practices in main plots and four cropping systems as in subplots with three replications. Among farming practices, organic farming practice resulted in significantly higher MGEY (7571.40 kg ha-1) and production efficiency (20.74 kg ha-1 day-1) over inorganic farming practice.Organic farming practice remaining at par with integrated farming practice resulted in significantly higher uptake of N, P, K and protein yield over inorganic farming practice. Organic and integrated farming practice outperformed inorganic farming practice in improving various soil properties. At the conclusion of the experiment, a reduction of 7.2% in bulk density was recorded under organic farming practice while inorganic farming practice resulted in an increase of 1.6% over its initial value. Soil organic carbon and microbial biomass carbon increased by 30 and 53%, respectively under organic farming practice while, inorganic farming practice resulted in a decrease of microbial biomass carbon by 1.06% over its initial value. Organic farming practice resulted in an increase of about 24, 50 and 28% inavailable N, P and K, respectively over its initial value while, its corresponding values under inorganic farming practice were 15, 35 and 20%. In the absence of premium pricing and comparatively lower yields of cereal crops under organic farming practice the inorganic farming practice resulted in higher net returns and benefit: cost ratio to that of organic farming practice. Legume based mash – gram cropping system improved the soil fertility status with respect to available N, P, K and soil physical and biological properties over all other cropping systems. While, maize – wheat and mash – wheat cropping systems remaining at par with each other resulted in significantly highest MGEY, production efficiency and net returns but benefit: cost ratio was significantly highest under mash – wheat cropping systemsover all other cropping systems.ThesisItem Open Access Development of Trichoderma virens knockout mutant for studying the role of a Glutathione S-transferase (GST) gene in secondary metabolism(Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur, 2019) G, Deepa; Kumar, AshishThesisItem Open Access An Economic Analysis of Farm Profitability & Efficiency of KVK Adopted Farmers in Sehore District of Madhya Pradesh((Rewa) Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur, 2019) Kumar, Ashish; Khan, N.ThesisItem Open Access Heterosis and combining ability analysis in relation to selection of parental lines in brinjal (Solanum melongena L.)(Sardar Vallabhbhai Patel University of Agriculture and Technology Meerut, 2018) Kumar, Ashish; Singh, BijendraThe present investigation entitled “Heterosis and combining ability analysis in relation to selection of parental lines in brinjal (Solanum melongena L.)’’was undertaken to collect information on genetic parameters for yield and its components from a eight parents in a half diallel mating design in brinjal at Horticulture Research Centre, Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut (U.P.) during Kharif,2016-17 and 2017-18. The experimental material was comprised of eight diverse parents and their 28 F1s. All genotypes were evaluated in a complete randomized block design with three replications. The data were recorded on twelve characters plant height (cm), primary branches per plant, plant spread (cm), days to first flowering, days to first fruit set, days to first fruit picking, average fruit weight (gm), length of fruit (cm), diameter of fruit(cm), fruit index, fruits per plant and yield per plant (g.). The data were recorded subjected to various statistical analyses. Analysis of variance observed highly significant differences among the parents and F1s for all the characters. It is logical to suggest the appropriate breeding methodology on the basis of genetic information gathered from the present studies in brinjal which allowed maximum exploitation of both additive and non additive components with gene action. Suggestions are advocated for consideration during formulation of breeding programme in brinjal on the basis of result obtained in the present investigation for fruit yield and its components governed by additive and non additive gene. There for progeny and recurrent selection may be recommended or improvement in fruit yield and its components in brinjal. The higher proportion of specific combining ability variance highly significant dominance and over dominance components for yield and its contributing traits would be helpful in commercial exploitation of hybrids in brinjal. Some crosses A. Parthibha x A. Abhilomb, JB-6 x DBL-24, F.Collection-2 x A. Abhilomb, F. Collection-2 x A. Parthibha (C.K.) were found good combination for further development and for further breeding program in brinjal. First two crosses (hybrids) recommended for commercial cultivation at the farmers field.ThesisItem Open Access In Virto Studies on Antagonistic Performance of Trichoderma Spp. against Different Plant Pathogenic Fungi(JNKVV, 2012) Sahu, Tarendra Kumar; Kumar, AshishThesisItem Open Access Isolation Identification Propagation of field strain of goat pox virus in embryonatd eggs and cell culture.(CHHATTISGARH KAMDHENU VISHWAVIDYALAYA, DURG, 2012) Kumar, Ashish; Hirpurkar, Dr. S.D.ThesisItem Open Access Morphological and Cultural Variability in Alternaria brassicae from major cruciferous crop((Rewa) Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur, 2018) Malakar, Lokesh; Kumar, AshishThesisItem Open Access Seasonal variation of groundwater quality of Jalalabad (West) block of the district Fazilka, Punjab, India.(Department of Soil Science and Agricultural Chemistry Institute of Agricultural Sciences Banaras Hindu University, Varanasi, 2019) Kumar, Ashish; Nath, TriyugiWater is a unique resource on the planet earth. It is very essential for sustaining all forms of life. Groundwater is defined as water that is present beneath the water table under earth’s exterior. Water in the ground passes through soil and rock pores, through fractures and weathered areas of the bedrock. Groundwater account for about 98% of the world's use of fresh water and is estimated 60 times as plentiful as fresh water found on lakes and streams and has a major effects on the habitats of rivers and wetland for crops, animals and aquatic life. As the groundwater is not visible that’s why it is often ignored in the consideration of all the waters on earth, yet groundwater is a valuable resource available and it should be use judicially. Water is also seen as a universal solvent to dissolve multiple things that are essential for the ecosystem's survival in turn, water is most important in many geological processes and can also be used for different use from the rainfall.
