This study was conducted to assess the effect of different sources of nitrogen (N) on productivity of soybean. It was consisted of seven treatments such as T1= recommended N (urea); T2=recommended farm yard manure (FYM) based on N equivalency (NE); T3=recommended biochar based on NE; T4=50% recommended FYM based on NE + 50% recommended N; T5=50% recommended biochar based on NE+ 50% recommended N; T6=50% recommended FYM + 50% recommended biochar based on NE; T7=33% recommended FYM + 33% recommended biochar based on NE + 33% recommended N. Treatments were replicated thrice in completely randomized design. Results indicated that the T3 treated soil resulted in the highest porosity and root length. The highest shoot N uptake and yield per plant (7.20g plant-1) was obtained for T1 which was statistically at par with T2 and T3, implies that the farmers can apply either FYM or biochar as source of N.
