Effects of rhizobium and fertilizer application on growth and yield of soybean cv. SJ.5

Treatment 1 (T1) application of lime, P2O5 and K2O the rate of 100, 9 and 6 kilograms per rai, respectively; Treatment 2 (T2) inoculated seeds with Bradyrhizobium, application of lime N, P2O5 and K2O at the rate of 100, 3, 9 and 6 kilograms per rai, respectively; Treatment 3 (T3) inoculated seeds with Bradyrnizobium and rock phosphate applied at the rate of 100 kilograms per rai; Treatment 4 (T4) inoculated seed with Bradyrhizobium and the application of lime and fertilizer 15-15-15 at the rate of 100 and 40 kilograms per rai respectively; Treatment 5 (T5) inoculated seed with Bradyrhizobium only; and Treatment 6 (T6) no application anything as control treatment. The shoot dry weight of all treatment entire the period of experiment tend to the similar. Only the some stage was noted significantly effected, especially in treatment 4 tend to gave the growth development higher than other. The plant height were not significantly different among the treatment. Number of nods per plant and number of branches per plant was noted not significant. The treatment (T2, T3 and T4) were inoculated with Rhizobium and fertilizer was noted higher number of nodule if compared with treatment (T1 and T6) their without inoculated with Rhizobium or T5 inoculated with Rhizobium only. The weight of nodule of every treatments was noted not significantly but higher than control. The yield component of soybean in term number of plants per square meter of all treatment was similar. Number of seed per square meter and number of pods per plant was noted in treatment 4 higher than other, but another treatment not significant. Number of pods per square meter, number of seeds per pod, weight of seed per one hundred seed and harvesting index of all treatment were showed not significant effects but treatment 4 tend to developed better. The total yield of soybean in treatment 4 gave higher yield than other significant difference with an average 547.20 kilogram per rai, treatment 1, treatment 3 and treatment 2, treatment 6 and treatment 5 was also noted with an average 443.80, 425.60, 425.00, 422.20 and 363.60 kilogram per rai, respectively. All treatment were showed not significant.
