A long-term fertilizer experiment under soybean-safflower cropping sequence was used to investigate the effect of organic and inorganic fertilizer applications on yield, uptake and microbial properties in soil. Application of 100% NPK +FYM @5 t ha-1 significantly highest grain yield of soybean (14.27q ha-1) and safflower (6.31q ha-1) followed by 150% NPK of soybean (14.13q ha-1) and safflower (6.24 q ha-1) and these treatments are found to be significantly superior than all treatments of long term fertilization. The microbial and enzyme activities are improved by application 00% NPK + FYM @ 5 t ha-1 and only FYM @ 10 ha-1 in soybean -safflower cropping sequence under Vertisol. Nutrient uptake of Nitrogen (113.02 kg ha-1), Phosphorous (23.91 kg ha -1) and Potassium (50.75 kg ha -1) by soybean and Nitrogen (56.50 kg ha -1), Phosphorous (23.50kg ha -1) and Potassium (75.62 kg ha -1) by safflower were recorded significantly maximum in 100% NPK +FYM @5 t ha-1 at harvest of both the crops. The balance application of chemical fertilizers improves physico chemical and biological properties soil than imbalance use of chemical fertilizers. The grain yield of soybean and safflower, nutrient uptake and soil biological properties were lowest in absolute control and only application of 100 % nitrogen in soybean safflower cropping sequence under Vertisol.
