| dc.description.abstract | A field experiment was conducted at experimental farm of BAU with Soybean (var. JS-335) as a test crop during the Kharif season (June to October, 2016) to study the combined application of Phosphorus and Sulphur along with Bradyrhizobium on yield and quality of soybean. The experiment was laid down with 18 treatment combinations with two levels of inoculation (I0 and I1), three levels of phosphorus (40, 60 and 80 kg ha-1) and three levels of sulphur (0, 15 and 30 kg ha-1) in split-split plot design with three replications. The soil of the experimental site was sandy clay loam in texture having good drainage and fairly moisture retention capacity with acidic pH (5.2), EC (0.08dS m- 1), low in organic carbon (2.6 g kg-1),CEC (8.5 cmol (p+) kg-1), total nitrogen (0.157 %) and available nitrogen (181.5 kg ha-1), medium in available phosphorus (23.9 kg ha-1) and available sulphur (17.0 ppm) was above the critical range. Microbial population in initial soil was 29.33×10 4 Propagules g-1, 22×10 6 CFU g-1, 8.9×10 6 CFU g-1 for fungi, bacteria and actinomycetes, respectively. The results revealed that different levels of phosphorus and sulphur along with microbial inoculation significantly influenced the nodulation parameters and yield attribute such as number of nodules (33.05), fresh weight of nodule (0.69 g), dry weight of nodule (0.31 g) and number of pods per plant (43.27) were recorded maximum with application of phosphorus @ 80 kg P2O5 ha-1 having statistical equivalence of 60 kg P2O5 ha-1 except fresh and dry weight of nodules per plant. Grain yield of soybean remarkably increased with increasing doses of phosphorus and recorded maximum of 23.91 and 27.13 q ha-1 grain and straw yield, respectively with 80 kg P2O5 ha-1. Application of 30 kg S ha-1 was found equally effective with application of 15 kg S ha-1 in respect to number of nodules, fresh weight, dry weight of nodule, number of pods per plant, grain yield and recorded maximum value of 31.38, 0.67 g and 0.30 g, 43.21 and 23.62 q ha-1, respectively with application of 30 kg S ha-1. Microbial inoculation significantly increased the number of nodules (33.77), fresh weight (0.69 g), dry weight of nodule (0.30 g), grain yield (23.36 q ha-1) and straw yield (26.43 q ha-1). Application of increasing levels of both phosphorus and sulphur along with microbial inoculation resulted in a significant increase in total nutrient uptake (N, P and S). Application of 80 kg P2O5 ha-1observed the highest total uptake of N, P and S of 185.66, 16.34 and 15.43 kg ha-1, respectively which was statistical equivalence with 60 kg P2O5 ha-1 in respect of total P uptake while, with application of 30 kg S ha-1 total N, P and S uptake were 183.36, 16.09 and 15.43 kg ha-1, respectively. Microbial inoculation recorded highest total N, P and S uptake of 180.97, 15.98 and 15.10 kg ha-1, respectively. Application of phosphorus and sulphur significantly enhanced the oil content in soya grain and highest oil content of 19.48 % and 19.44 % with 80 kg P2O5 ha-1 and 30 kg S ha-1, correspondingly and having statistical equivalence with 60 kg P2O5 ha-1 and 15 kg S ha-1. Nutrient status in soil after crop harvesting were appreciably improved due to phosphorus treatments and significant results were found in available nitrogen (221.39 kg ha-1) and phosphorus (30.9 kg ha-1) with 80 kg P2O5 ha-1 while, it was comparable with application of 60 kg P2O5 ha-1 in respect to available nitrogen. Soybean variety JS-335 gave the highest yield as well as net returns to the tune of ` 41955.77 ha-1 with B : C ratio of 1.68 when it was fertilized with phosphorus @ 80 kg P2O5 ha-1 and sulphur @ 30 kg S ha-1 along with microbial inoculation. | en_US |
