Abstract: This study aimed to investigate the impact of long term application of inorganic fertilizers and farmyard manure on pattern of nutrient content and nutrient uptake of soybean in black soil. The field experiments was conducted on the Research Farm of Department of Soil Science and Agricultural Chemistry, JNKVV, Jabalpur during 2017-18 and 2018-19 with ten treatments i.e. 50% NPK, 100% NPK, 150% NPK, 100% NPK+HW, 100% NPK+ Zn, 100% NP, 100% N, 100% NPK+FYM, 100% NPK-S and control. The highest content and uptake pattern of nutrient in soybean ware associated with integrated application of fertilizer along with Farmyard manure (100% NPK + FYM). While, the lowest value was found in control as well as 100% N alone. But supplementation of fertilizer P with N (100% NP) enhanced the content uptake in soybean. Moreover, applied 150 % NPK observed the higher value as compared to 100 % NPK and 50% NPK. However, in general higher content and uptake of nutrients were found in grain as compared to straw.
