Abstract
Owing to the rising costs of chemical fertilizers and the growing environmental concerns, there is an ever increasing interest in the role of soil microorganisms in crop nutrition and soil fertility restoration. A field study was therefore conducted to determine the influence of Bradyrhizobium inoculation, N and P fertilizers application on nodulation, yield and yield attributes of soybean at Pawe. Three levels of N (0, 11.5 and 23 kg N ha-1); three levels of P (0, 23 and 46 kg P2O5 ha-1) with two levels of Bradyrhizobium were arranged in RCBD in factorial combinations with three replications. Nodule number, nodule weights, plant height, number of pods and number of seeds, 100 seeds weight and grain yield responded significantly to the interaction effects of B. japonicum with N and P fertilizers. Seed yield, biomass yield, and harvest index were significantly affected by the main effects of any one or more of the factors and interaction of any two of the factors. The maximum numbers of nodules of 80.26, fresh and dry weights of 3.77 and 0.99 gm/plant respectively; 100-seed weight of 16.96 gm, number of pods of 80.66 and grain yield of 3151.88 kg/ha were measured by combined effect of 11.5 kg N/ha, 46 kg P2O5/ha and B. japonicum. The highest plant heights of 79.26 cm, and 100.60 numbers of seeds were measured after applications of 46 kg P2O5/ha with B. japonicum. Each nodule attributes were significantly and positively correlated each other and with each yield and yield attributes. The results showed that growth and yield potential of soybean and an increase N2 fixing can be achieved by using inoculation of B. japonicum and P application alone or in combination with B. japonicum, or P with small dose of N fertilizer. The results obtained in this work might have potential applications for increasing the productivity of soybean and enriching the soil with N.
