Effect of nitrogen source diversification in vertisols on the economics of soybean productivity

Abstract

The current investigation examined the Effect of Nitrogen Source Diversification in Vertisols on the economics of Soybean Productivity. in the year 2017-18 at Research Farm of Department of Agronomy, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (Maharashtra). The soil was clayey in texture which as dominated by smectite clay minerals belongs to hyperthermic family of Typic Haplustert having swell shrink property of experimental plot. The soil exhibited a slightly alkaline reaction (pH 8.6), contained a medium level of organic carbon (0.52%), had low concentrations of nitrogen (216.5 kg ha⁻¹) and phosphate (16.86 kg ha⁻¹), but was very high in exchangeable potassium (367.22 kg ha⁻¹). During the cropping period, 378.8 mm of rainfall was recorded, which was below the normal level of 567.9 mm for that duration. The experiment was laid out in randomized block design with three replications. The other inter-cultivation practices were kept common as recommended, while the nutrients were provided as per the treatments of nutrient management. Different parameters were studied as Soybean growth characters, the yield contributing characters. It is concluded on economics the highest GMR, NMR and B:C ratio were recorded with application of RDF through chemical fertilizers over rest of treatments and found corresponding with 50% RDN + 50% RDN through vermicompost.
