ThesisItem Open Access Distribution of macro and micronutrients in soils of Kirnapur Block, Balaghat District (M.P).(Department of Soil Science & Agricultural Chemistry Institute of Agricultural Sciences Banaras Hindu University Varanasi, 2022) Eadpache, Barkha; Eadpache, Barkha; Eadpache, Barkha; Sharma, P. K.; Sharma, P. K.; Sharma, P. K.The distribution of macro and micronutrients in soils of Kirnapur Block, Balaghat District" was conducted, and it is located at 21.37°N, 80.20°E. It has an elevation of 295 metres on average. The total geographical area of Kirnapur Block is approximately 881 km2.Total 50 soil samples were collected from various locations throughout the Block. Soil samples were collected and tested for various physico-chemical properties such as Bulk density, Particle density, Water holding capacity, Porosity, pH, EC, OC and macronutrients such as N, P, K, S and also micronutrients such as Zn, Mn, Fe, Cu using standard analytical methods. The soil nutrient index values of the Kirnapur Block were low for nitrogen, potassium, Sulphur and Zinc, whereas medium for Phosphorus, Copper, Manganese, and Iron. The spatial variability map of nutrients also clearly indicate its distribution pattern in the sampled soil Because of the Balaghat District Cropping pattern is Rice-fallow-Fallow / Rice-Rice-Fallow. It has also been a significant factor in driving farmers toward a dangerous situation that urgently needs for a solution and the largest rice-growing region is Balaghat.ArticleItem Open Access Effect of different water regimes and nitrogen application on growth, yield, water use and nitrogen uptake by pearl millet (Pennisetum glaucum)(2003) Singh, R. K,; Chakraborty, D.; Garg, R. N.; Sharma, P. K.; Sharma, U. C.ThesisItem Open Access Effect of different zinc application method on growth, yield and quality of kharif maize (Zea mays L.) in red soils of Vindhyan region(Department of Soil Science and Agricultural Chemistry Institute of Agricultural Sciences Banaras Hindu University, Varanasi, 2018) Verma, Ravi; Sharma, P. K.The present investigation was conducted during rainy (kharif) season of 2017 at the Agricultural Research Farm of Rajiv Gandhi South Campus, Banaras Hindu University, Barkachha, Mirzapur. The experimental area falls under semi-arid to sub-humid climate and the experiment was laid out under rainfed situations and the soil of the experimental field was sandy clay loam in texture, well drained and medium acidic soil reaction (pH 5.4). It was moderately fertile, being low in organic carbon (0.28%), low in available nitrogen (202.36 kg ha-1), and medium in available phosphorus (19.55 kg ha-1) and medium in available potassium (235.75 kg ha-1). The factorial experiment was layout in Randomized Block Design with three replications. The experiment comprises 12 treatment combinations of three foliar application of zinc levels (F1: control, F2: 0.1% and F3: 0.5%) and four soil application of zinc levels (S1: control, S2: 5 kg ha-1, S3: 10 kg ha-1 and S4: 15 kg ha-1). Looking to the result of the present study, application of 15 kg ha-1 Zn produced highest grain yield among all soil applied Zn treatments. However 0.5 % foliar application of Zn gave higher grain yield than 0.1 % foliar application.ThesisItem Open Access Effect of organic and inorganic sources of nitrogen on yield, quality of wheat and soil fertility in Inceptisol of Varanasi(Department of Soil Science and Agriculture Chemistry, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, 2021) Singh, Kajal; Sharma, P. K.Abstract Inadequacy of fertilizers and their rising cost is a serious limitation for crop production. The imbalance between nutrient demand and supply is increasing exponentially day-by-day. Excessive use of agrochemicals such inorganic fertilizers, pesticides, herbicides, fungicides, etc. has caused severe effects to human, soil and environmental health are being seriously affected. This experiment is conducted to assess the effects of organic amendments and their substituting capacity for supplementing inorganic fertilizers to some extent. Observations were made that integration of organic manures and inorganic fertilizers gave superior results. Among various organic amendments, poultry manure proved to be the best option as it has highest amount of nutrient content. Yield attributes such as plant height, number of spikes per plant, number of spikelets, spike length, grain yield, stover yield and harvest index along with the quality of grains were significantly influenced by the applied organic amendments. Post-harvest soils were also affected by the kind of manures applied and hence the changes in physicochemical properties of soils were observed. In this study, proofs have been given that optimum doses of fertilizers maintain higher yield of crop and causes minimum damage to ecosystem. Sustainability can be achieved with the help of organic amendments as these conserves physico-chemical properties and soil fertility. This study focuses on benefits of integration nutrient management which is the urgent need of current scenario.ThesisItem Open Access Molecular Diversity Among Diazotrophs In Arid Zone Soils Of Haryana(Chaudhary Charan Singh Haryana Agricultural University; Hisar, 2005) Sarita; Sharma, P.
