Field experiments were conducted during the kharif seasons of 2015 and 2016 to evaluate the efficacy of the organically managed cropping system in improvement of soil health in NE hill region. Four combinations of two cropping systems (C), viz., rice-greengram (C1) and maize-greengram (C2) and two organic N management treatments (N), viz., 75 % RD through vermicompost (N1) and 100 % RD through vermicompost (N2) and two organic phosphorus management treatments (P) viz., 75 % RD through vermicompost (P1) and 100 % RD through vermicompost (P2), which was applied to succeeding crop of greengram after the main kharif crops, were evaluated under the trial in split plot design. Yield and yield attributing characteristics of greengram viz., no. of pods/plant, no. of seeds/pod, test weight, seed yield, stover yield and harvest index (HI) were found to be significantly higher under cropping system C2 and organic nutrient management treatments N2 and P2 during both the years. Maximum rice and maize equivalent yield of greengram was also recorded under the cropping system C2 and organic nutrient treatments N2 and P2 during both years. Significant increase in soil organic C, pH, available N, P2O5 and K2O both before sowing and after harvest of first (rice and maize) and second (greengram) kharif crops was recorded under the cropping system C2 and organic nutrient management treatments N2 and P2.
