A field experiment was carried out to study the effect of N management on soil fertility and nutrient uptake in soybean. The study revealed that both seed and straw yield were significantly increased with increase in N dose with declining yield response at higher level. However, NPK uptake by soybean increased significantly with increasing levels of nitrogen. Integration of chemical fertilizer with Rhizobium increased seed yield and NPK uptake. Splitting half of N at 50 days after sowing (DAS) was found significantly better over 80 DAS.
