ThesisItem Open Access Effect of crop geometry and nitrogen management on yield and nutrient stoichiometry of pearl millet (Pennisetum glaucum L.) under guava based agri-horti system(Department of Agronomy Institute of Agricultural Sciences Banaras Hindu University Varanasi, 2020) Minz, Srishti Dipriya; Prasad, S.K.This study explored the effect of crop geometry and nitrogen management on yield nutrient stoichiometry of pearl millet (Pennisetum glaucum L.) grain under guava based agri-horti system. The experiment was conducted at Agricultural research farm of Rajiv Gandhi South Campus, BHU, Barkachha in 3 x 4 randomized block design (factorial) with three replications. The soil of the experimental plot is sandy-loam in texture with pH 5.38.The treatment consisted of three different crop geometry (45 x 15, 40 x 20 and 30 x 20 cm) and four different nitrogen mnagement (0% RDN, 100% RDN by urea , 75% RDN by urea + 25% RDN by FYM and 50% RDN by urea + 50% RDN by FYM). Findings of the study demonstrated that significantly maximum growth parameters viz., plant height, leaf area index, crop growth rate, relative growth rate, maximum yield and yield attributes viz., Panicle length, Panicle girth, Grain panicle-1 test weight, grain yield, biological yield and harvest index were recorded in the crop geometry 40cm x 20cm with application of 100% RDN by urea. Similarly higher nutrient content, uptake and stoichiometry was obtained in the crop geometry 40cm x 20cm with application of 100% RDN by urea. We conclude that the crop geometry 40cm x 20 cm and application 100% RDN by urea enhance the yield, nutrient content and stoichiometry of pearl millet in comparison to the other treatments.ThesisItem Open Access Effect of FYM and nitrogen on yield and nutrient Stoichiometry of Pearl Millet under custard based Agri-horti System.(Department of Agronomy Institute of Agricultural Sciences Banaras Hindu University, Varanasi, 2019) Rana, Rekha; Prasad, S.K.The present investigation entitled “Effect of FYM and nitrogen on yield and nutrient stoichiometry of pearl millet under custard based Agri-horti system” was conducted during kharif season of 2018 at agriculture research farm of Rajiv Gandhi South Campus, Banaras Hindu University, Varanasi, Uttar Pradesh. The experiment was performed in eleven years old custard apple plantation which was planted in August, 2006 at a spacing of 5 × 5 m along with three FYM level (control, 10 and 15 ton ha-1) and four different rates of nitrogen (control, 50,80 and 110 kg ha-1). The experiment was laid out in a factorial randomised block design with three replication. Result revealed that significant variations were observed due to different level of farm yard manure and application of 15 ton/ha recorded significantly highest plant height (161.25 cm), internode length (16.93), no. of tillers plant-1 (1.11), dry matter accumulation (30.81g), leaf area index (2.33), grain yield (1632.67 kg ha-1) and stover yield (5181.14 kg ha-1). Successive increase in nitrogen application of 110 kg ha-1 recorded significantly highest plant height (177.66 cm), internode length (18.16), panicle length (24.17 cm), test weight (10.02 g), grain yield (1770.08 kg ha-1, stover yield (5068.44 kg ha-1), agronomic efficiency (4.49 kg grain kg-1 N uptake) and agronomic recovery efficiency (29.07 %). Significantly maximum gross return (44653.42 Rs ha-1) and B:C ratio (1.64 %). Among sources of nitrogen, application significantly highest nutrient stoichiometry in grain N:P (2.01), P:K (0.75) and N:K (1.21).ThesisItem Open Access Effect Of Organic Matter And Inorganic Fertilizers Of Soil And Plant Nematodes .(IARI, Division of Nematology ; New Delhi, 1982) Mishra, S.D.; Prasad, S.K.ThesisItem Open Access Effect of row spacing and nitrogen rates on growth and yield of barley (Hordeum vulgare l.) under guava (Psidium guajava l.) based agri-horti system(Department of Agronomy Institute of Agricultural Sciences Banaras Hindu University Varanasi, 2021) Suryavanshi, Roshni; Prasad, S.K.A field experiment was carried out at Agricultural Research Farm, Rajiv Gandhi South Campus, Banaras Hindu University, Barkachha, Mirzapur (Uttar Pradesh) to evaluate the influence of varying row spacing and nitrogen rates on growth and yield of barley under guava based agri-horti system. The experimental design was Factorial RBD consisted of three row spacings (15, 20 and 25 cm) and four nitrogen rates (0, 75, 100 and 125 kg ha-1). The findings of the statistical analysis showed that row spacing and nitrogen rates had significant impact on growth attributes. Row spacing of 20 cm registered significantly higher values of almost all growth attributes viz. plant height, tiller count per metre row length, shoot dry matter accumulation and leaf area index (LAI) followed by 15 and 25 cm row spacing. However, crop growth rate and net assimilation rate were highest under 15 cm row spacing followed by 20 cm and 25 cm. In nitrogen rates, 125 kg ha-1 recorded higher values of all the growth attributes over 0, 75 and 100 kg ha-1. The row spacing of 20 cm was at par with 15 cm row spacing in most of the yield parameters i.e., number of effective tillers, 1000-grain weight and grain count per ear head. While, ear length was significantly higher under 20 cm followed by 15 and 25 cm row spacing. Nitrogen application @125 kg ha-1 registered maximum values of all the yield attributes followed by 0, 75 and 100 kg ha-1 nitrogen rate. Grain yield was significantly influenced by row spacing and maximum grain yield (3347.74 kg ha-1) was obtained with 20 cm row spacing. Whereas, straw yield, biological yield and harvest index were not influenced significantly due to row spacing. Treating with nitrogen @125 kg ha-1 recorded significantly higher grain yield (3635.37 kg ha1) over control, 75 and 100 kg ha-1 nitrogen level. Maximum straw yield, biological yield and harvest index were also recorded under 125 kg ha-1 nitrogen rate. Highest gross return, net return and B:C ratio was obtained with 20 cm row spacing as compared to 15 and 25 cm row spacing. In case of nitrogen rates, highest net return and B:C ratio was registered by 125 kg ha-1 nitrogen rate. Partial factor productivity (PFP) was found maximum with 75 kg N ha-1. While, agronomic efficiency of applied nitrogen was highest under 125 kg ha-1 nitrogen dose.ThesisItem Open Access EFFECT OF SEED INOCULATION AND FERTILITY LEVELS ON GROWTH, YIELD ATTRIBUTES AND YIELD OF MUNGBEAN (Vignaradiata L.) UNDER GUAVA BASED AGRI-HORTI SYSTEM(Department of Agronomy Institute of Agricultural Sciences Banaras Hindu University, Varanasi, 2018) Kannaujiya, Ashish; Kannaujiya, Ashish; Prasad, S.K.; Prasad, S.K.A field experiment was conducted at Research Farm, Rajiv Gandhi South Campus Barkachha Mirzapur (U.P.), Institute of Agricultural Sciences, BHU, Varanasi-221005. Agroforestry an approach to land use that incorporates trees into farming systems, and allows for the production of trees and crops or livestock from the same piece of land in order to obtain economic, environmental, ecological, and cultural benefits.Mungbean(VignaradiataL.) is an important pulse crop of India. It is a short duration, highly productive crop and rich sources of protein.Nitrogen is an essential element for proper plant growth and development.Phosphorus has novel function of special importance in the process of energy storage and transfer.Inoculation in these crops was found to increase the crops yield by about 10-15 % under on farm condition.Guava trees are easy in establishment, tolerate the shock exerted during the course of pruning, exert least competition to nutrient and moisture to the crop grow together.The soil of the experimental field was sandy loam-silt in texture with pH 4.55. It was moderately fertile with organic carbon (0.28 %), available nitrogen (202.36 kg ha-1), and available phosphorus (16.57 kg ha-1).The taller plant height was obtained with the N60 P120and with rhizobium whereas the smallest with control (no application).The fertility treatment the maximum number of trifoliate leaves plant-1 obtained in N60 P120 with rhizobium.The yield attributes viz., number of pods plant-1, pods length, number of grain pod-1 and 1000 grain weight were recorded higher in seed inoculation with fertility levels N60 P120 with rhizobium. Interaction between seed inoculation and fertility levels had non-significantly effect on yield attributes.The maximum and the minimum gross return were obtained from seed inoculation with fertility treatment N60 P120 and minimum control (no application). The maximum net return and benefit cost ratio were also obtained from N60 P120 with rhizobium.ThesisItem Open Access Effect ofFYM and nitrogen levels on yield and nutrient stoichiometry of pearl millet (Pennisetum glaucum L.) under bael(Aeglemarmelos L.) based agri-horti system.(Department of Agronomy Institute of Agricultural Sciences Banaras Hindu University Varanasi, 2018) Hembrom, Rashmi Sweta; Prasad, S.K.Nutrient stoichiometry suggests that plant C,N,P and K ratios respond to changes in the C:N:P:Kstoichiometry and its availability.Here, the experiment was conducted in research farm of RGSC,BHU Mirzapur. The experiment was conducted in two plots in agri-horti system and in the sole cropping field. The uniform application of nutrients FYM (7,10,13) tonnes ha-1and N (0, 60, 90, 120) Kg ha-1was applied on it. Its yield and nutrient stoichiometry was observed. The highest yield of pearl millet crop was obtained with the application of nitrogen 120 N kg ha-1and FYM level 13 t FYM ha-1 from agri-horti system.The highest net returns (Rs 36092.72 ha-1) and B:C(5.52 %) was obtained with theapplication of nitrogen 120 kg N ha-1from agri-horti system.The growth of pearl millet was co-limited by C:N, C:P, and P:K ratio with the application of F0N0from open field and agri-horti system. It has broaden the essentiality of nutrient stoichiometry in plant growth.The nutrient stoichiometry of crops has implications for both decomposers and consumers, and stoichiometric concepts might be of interest in fertiliser management and modelling.Variability in nutrients stoichiometry related to plant storage products, however, restricts in its application.ThesisItem Open Access Serological and genetical studies on bovine lymphocyte antigens.(NDRI, Karnal, 1989) Kumar, Naresh; Prasad, S.K.ThesisItem Open Access Studies on cellular and humoral immune response in cattle.(NDRI, Karnal, 1990) Bhasin, V.; Prasad, S.K.ThesisItem Open Access Study of growth, yield and nutrient stoichiometry of wheat (Triticum aestivum L.) varieties.(Department of Agronomy Institute of Agricultural Sciences Banaras Hindu University Varanasi, 2022) Patel, Anjani Kumar; Prasad, S.K.A field experiment was conducted on “Study of growth, yield and nutrient stoichiometry of wheat (Triticum aestivum L.) varieties” during the Rabi season of the year 2021-22 at agriculture Research Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi on sandy clay loam soil with pH 7.41, low in organic carbon (0.38%), low in available nitrogen (201.23 kg ha-1) and medium in available phosphorus (18.82 kg ha-1) and potassium (180.41 kg ha-1).
