Nutrient management through organic sources would facilitate in achieving the required productivity and sustainability by the efficient use of soil and applied plant nutrients. The present investigation has been made to study the effect of DAP and NAA spray along with bio-fertilizers for black gram, rice fallow crop in the deltaic region. The results revealed that applications 2 per cent DAP + Rhizobium + Phosphobacteria (M2S2) recorded the highest value of growth and yield attributes and yield of blackgram. The maximum yields were recorded as 1564 kg ha−1 and 1799 kg ha−1 respectively in two seasons (M2S2) when compared to other treatments.
