Abstract:
A field experiment was conducted during August – November (Late kharif) 2020 at the research farm of Department Soil Science and Agricultural Chemistry, NAI, SHUATS, laid out in Randomized Block Design. To achieve higher growth and yield of rainy cowpea variety GOMATI, it was found application of T5 @ 50% NPK+ @ 50% Boron + @ 50% Zinc has shown effective growth under Prayagraj climatic conditions. It was observed that for physical and chemical properties of soil in treatment T5 @50% NPK + @ 50% Boron + @50% Zinc were improved significantly due to application of Nitrogen, Phosphorus, Potassium, Boron and Zinc use of inputs. The results showed that progressive increase of Bulk density (Mg m^-3) as the depth increase, pH of the soil is increased as the depth increase as the fertilizer used was Di Ammonium Phosphate and use of MOP does not affected the soil pH, use of Borax and Zinc sulfate increased the soil pH., Pore space (%) of the soil decreased as the depth of the soil increases, Water Holding Capacity (%) of the soil is increased as the depth of the soil increases, Electrical conductivity (dS m^-1) of the soil is increased as the depth of the soil is increased, Organic Carbon Content (%) of the soil is decreased as the depth of the soil is increased, available Nitrogen (kg ha^-1), available Phosphorous (kg ha^-1), available Potassium (kg ha^-1), available Boron (kg ha^-1), available Zinc (kg ha^-1) in soil is decreased as the depth of soil is increased and the plant height, Number of branches, Number of seeds per pod, Number of pods per plant and pod yield has increased with the application of inorganic fertilizers and micronutrients.
