STCR Based site specific nutrient management in soybean-safflower cropping system

Abstract

Experiment was conducted at research farm of AICRP on safflower research project, VNMKV, Parbhani during kharif and rabi seasons 2022-23, to study the impact of site specific nutrient management through soil test crop response on yield and economics of soybean-safflower cropping system. Experiment was conducted in split plot design with three replications. The main plot treatment consist of sowing of soybean normal duration variety and short duration variety in kharif season followed by sowing of safflower in rabi season with four subplot treatment of STCR equation based fertilizer application. The result revealed that seed yield of safflower after normal duration (1156 kg/ha) and short duration soybean variety (1257kg/ha) was significantly influenced due to early time span of short duration soybean variety. Application of 100% STCR based fertilizer application recorded highest seed yield (1585 kg/ha) which was Followed by 75% STCR based fertilizer application (1303 kg/ha). Similarly in system gross returns, system net returns and system B:C ratio also significantly higher with application of 100% STCR Based fertilizer application treatment.
