dc.description.abstractA field experiment entitled “Effect of Phosphorus, Sulphur and Gibberellic Acid on Growth, Yield and Quality of Soybean [Glycine max (L.) Merrill]” was conducted at Instructional Farm, College of Agriculture, Ummedganj, Agriculture University, Kota (Rajasthan) during kharif season 2020 on clay loam soil. The experiment comprised 24 treatment combinations, having four levels of phosphorus viz., 0, 20, 40 and 60 kg ha-1, three levels of sulphur viz., 15, 30 and 45 kg ha-1 and foliar spray of gibberellic acid viz., no spray and spray of GA3 @ 75 ppm laid out in sub-sub split plot design with three replications. Results showed that application of 60 kg P2O5 ha-1 had significant effect on plant height, dry matter accumulation plant-1, branches plant-1 at 30, 60 DAS and at harvest, while root nodules plant-1 and their dry weight at 45 DAS, number of pods plant-1, seeds pod-1, test weight (g), seed yield (1956 kg ha-1), straw yield (3427 kg ha- 1), biological yield (5383 kg/ha), nitrogen (6.47 %), phosphorus (0.65 %), sulphur (0.45 %) content in seed, oil and protein content in seed over application of 20 kg P2O5 ha-1 and control. The available nitrogen (290 kg ha-1), phosphorus (34.45 kg ha- 1), potassium (443 kg ha-1) and sulphur (22.77 kg ha-1) in soil significantly higher under application 60 kg P2O5 ha-1 over 40, 20 kg P2O5 ha-1 and control. However, it was found at par with application of 40 kg P2O5 ha-1. Significantly higher net return (・ 46771 ha-1) and B: C ratio (1.51) were also recorded with application of 60 kg P2O5 ha-1.Application of 45 kg sulphur ha-1 had significantly higher plant height (cm) at 60 DAS and at harvest, dry matter accumulation (g plant-1) at 30, 60 and at harvest stages, branches plant-1 at 30, 60 and at harvest stage, number of root nodules and their dry weight (g), number of pods plant-1, number of seeds pod-1, test weight (g), seed yield (1742 kg ha-1), straw yield (3083 kg ha-1), biological yield (4824 kg ha-1), phosphorus and sulphur content in seed and straw, oil & protein content (%) and their yield (kg ha-1). While, nitrogen and potassium content (%) in seed and straw, uptake of nitrogen, phosphorus, potassium and sulphur by seed, straw and total, available nitrogen (285 kg ha-1), phosphorous (29.50 kg ha-1), potassium (433 kg ha-1) and sulphur (23.05 kg ha-1) in soil significantly increased under application of 45 kg sulphur ha-1 , which was found at par with application of 30 kg sulphur ha-1 over 15 kg sulphur ha-1. However, net return (・ 36385 ha-1) and B: C ratio (1.18) was highest with application of 30 kg sulphur ha-1 over rest of treatments. Application of gibberellic acid @ 75 ppm as foliar spray gave significantly higher plant height (cm) at 60 DAS and at harvest stage, dry matter accumulation (g plant-1) at 60 DAS and at harvest, branches plant-1 at 30, 60 DAS and harvest, number of pods plant-1, seeds pod-1, test weight (g), seed yield (1770 kg/ha), straw yield (3002 kg ha-1) and biological yield (4736 kg ha-1), oil and protein content (%) and their yield (kg ha-1) and net return (・ 37769 ha-1) & B: C ratio (1.16) over control. Whereas, uptake of nitrogen, phosphorus, potassium and sulphur by seed straw and total was found significantly higher over control.en_US
