Abstract: A field experiment was carried out during 2016 at the Instructional-cum-Research (ICR) farm, Assam Agricultural University, Jorhat. The experiment was laid out in a split-plot design with three replications. The experiment included the possible combinations of three tillage practices in main plots viz., minimum tillage (T1), zero tillage with non-selective herbicide (Glyphosate) (T2) and conventional tillage (T3) along with sources of nutrient - recommended doses of fertilizer (F1) 60:20:40 N:P2O5:K2O kg/ha, 50% N replacement through Vermicompost + 50% RDF of N and full RDF of P2O5 and K2O (F2) and 50% N replacement through Enriched compost + 50% RDF of N and full RDF of P2O5 and K2O (F3) in sub plots. The results revealed that the highest available N, P2O5 and K2O in soil were found in zero tillage which was significant to minimum tillage and conventional tillage. Among the nutrient management practices, 50% N replacement through Enriched compost +50% RDF of N and full RDF of P2O5 and K2O recorded significant effect of available N, P2O5 and K2O content in soil.
