ESTIMATING THE EFFECT OF COMBINE USE OF RHIZOBIUM INOCULATION AND PHOSPHORUS FERTILIZER ON GROWTH, NODULATION AND YIELD OF Binasoybean-1 (Pages : 4 - 10)

Application of the optimum dose of the combination of Rhizobium inoculation (RI) and phosphorus (P) fertilizer could be an important factor to get maximum yield in soybean. The experiment was conducted at Noakhali Science and Technology University Field Laboratory to examine the effect of different combine doses of RI and P on nodulation, growth, and yield of Binasoybean-1. Four levels of RI (0, 25, 50, 75 g kg-1 seed i.e. I0, I1, I2, I3) and P (0, 18, 36, and 54 kg P ha-1 i.e. P0, P1, P2, P3) were applied. Plant height and no. of nodule plant-1 showed significant interaction effect between different levels of RI and P at all sampling dates. Dry weight plant-1 showed significant at 60 and 75 days after sowing (DAS) whereas insignificant result showed at 45 DAS. The highest plant height, no. of nodule plant-1 and dry weight plant-1 were observed in 75 DAS with the combinations of RI and P rates at I1P0 (25 g kg-1 seed and 0 kg P ha-1), I1P1 (25 g kg-1 seed and 18 kg P ha-1) and I3P1 (75 g kg-1 seed and 25 kg P ha-1) respectively. The interaction effect between the different levels of RI and P with the no. of pods plant-1, no. of effective pods plant-1, no. of seed pod-1 and 1000 seed weight were statistically significant, whereas insignificant relation with the no. of non-effective pods plant-1 and pod length. Besides, total node number and plant dry weight without seed at harvest stage showed a highly significant positive correlation with seed yield, indicating higher vegetative growth increase seed yield of soybean. Among sixteen treatment combinations, the highest seed yield (2.297 t ha-1) was obtained from the treatment combination of I2P3 (50 g kg-1 seed and 54 kg P ha-1) and it may be suggested as a proper dose of RI and P for Binasoybean-1.
