Abstract

To study the effect of various fertilizer doses and manurial treatment in soybean-safflower cropping system on soil properties , yield and nutrient uptake. The soil samples were drawn from the Research farm, Marathwada Ag- ricultural University, Parbhani with an objective to study changes in soil quality and crop productivity under soy- bean safflower cropping system included with various combinations of N, P, K, Zn, S fertilizers and mannurial FYM treatments. Results from the study showed that the maximum nutrient total uptake of N, P and K in soybean and safflower was recorded due to application of 100 % NPK + FYM @ 10 Mg/ha where as maximum total sulphur up- take in soybean (19.58 kg/ha) and in safflower (18.19 kg/ha) was recorded in treatments applied with 150% NPK and 100% NP + on residual effect of FYM respectively. Zinc uptake was maximum with 100% NPK + FYM @ 10 Mg/ha and in safflower it was recorded highest in 100% NP + residual effect of FYM. And also noticed that after continuous intensive cropping under various fertilizers with FYM treatment improvement occurred in the grain and straw yield and status of soil pH, EC, organic carbon, available N, P O , K O, S and DTPA extractable Zn. Use of 2 5 2 FYM and micronutrients helped in maintaining soil fertility. Highest net returns were recorded with 100% NPK + FYM.
