Abstract:
Inorganic fertilizers and micronutrient are important for crop productivity and soil health. A field experiment was conducted on cluster bean crop during August-November (Late kharif) 2020 at the research farm of Department of Soil Science and Agricultural Chemistry, NAI, SHUATS. The experiment was laid out in Randomized Block Design with 9 treatment combinations Nitrogen, Phosphorus, Potassium, Sulphur and Zinc (0% NPK S Zn, 50% NPK S Zn, 100% NPK S Zn) with 3 replications respectively. It was observed that for physical and chemical properties of soil and growth, yield and economic parameters in treatment T₉ @100% NPK, @100% S, @100% Zn were improved significantly due to application of Nitrogen, Phosphorus, Potassium, Sulphur and Zinc. The results showed that progressive increase of bulk density (Mg m^-3), Particle density (Mg m^-3), Pore space (%), Water Retaining Capacity(%), Soil pH, Electrical Conductivity (dS m^-1) of soil is increased as the depth of soil increased, Organic Carbon, Available Nitrogen (kg ha^-1), Available Phosphorus (kg ha^-1), Available Potassium (kg ha^-1), Available Sulphur (kg ha^-1) and Available Zinc (ppm) in soil is decreased with increase in soil depth.
