Abstract

A field experiment was conducted during kharif season of 2014 to study the effect of integrated nutrient management on growth, yield and nutrient uptake of clusterbean (Cyamopsis tetragonoloba). Significant improvement in growth, yield and nutrient uptake was recorded with sole and integrated application of nutrients through chemical fertilizers and biofertilizers. The results showed that application of 50, 75 and 100 % of recommended dose of fertilizer (20 kg N, 40 kg P2O5 /ha) was 21.2, 45.7 and 50.8 % over the control respectively. Association between Rhizobium and phosphate solublising bacteria was synergistic and inoculation of both fertilizers significantly improved the seed yield. Inoculation of Rhizobium, phosphate solublising bacteria and Rhizobium + phosphate solublising bacteria recorded 21.1, 14.1 and 24.7 % higher seed yield than the control respectively. However, the combination of both inoculants further failed to significantly increase the seed and straw yield of clusterbean further.
