Abstract:
A field experiment was conducted at Crop Research Centre, School of Agriculture, ITM University, Gwalior – 474001 (M.P.) during the kharif season 2022 to study the effect of phosphorus and potassium levels on yield and economics of soybean (Glycine max L.) in factorial randomized block design (FRBD) with three replications and a absolute control. The variety JS-1050 was sown along with phosphorus levels (0, 20, 40 and 60 kg ha^-1) and potassium levels (0, 15, 30 and 45 kg ha^-1). The soil of the experimental field was sandy loam in texture, having a pH of 7.35, organic carbon of 0.41%, and available nitrogen (178.03 kg ha^-1), phosphorus (24.45 kg ha^-1) and potassium (382.15 kg ha^-1) respectively. The result of the experiment revealed that an increase in the application of phosphorus and potassium had significantly increased the growth, yield and quality of soybean. Among the phosphorus levels 60 kg ha^-1 will be significantly higher over the remain phosphorus levels followed by 40 kg ha^-1 then 20 kg ha^-1. And among the potassium levels 45 kg ha^-1 will be at par with 30 kg ha^-1 both surpassed over 15 kg ha^-1. On the basis of economics, the highest net return (Rs. 85691 ha^-1) was recorded under the combination of 60 kg ha^-1 P₂O₅ + 45 kg ha^-1 K₂O has been recorded with the Benefit-cost ratio (Rs. 2.05 re^-1 invested).
