A field experiment was conducted at Instructional-cum-Research (ICR) farm, Assam Agricultural University, Jorhat-13, Assam during kharif 2015. The experiment was laid out in split-plot design replicated thrice with four sowing dates in main plots viz., 1st May (D1), 11th May (D2), 21st May (D3) and 31st May (D4) along with two methods of sowing viz., direct seeding (M1), transplanting (M2) and two nutrient management practices viz., RDF (F1) and INM package (F2) in sub-plots. Results revealed that May 31st (D4) recorded significantly higher in N,P2O5, K2O content followed by May 21st (D3). Between the two methods of sowing, direct seeding (M1) resulted superior in regards of fertility content but there was no statistical significance. In nutrient management practices, INM (F2) resulted in higher available N, P2O5, K2O content than that in RDF (F1).
