Effect of Different Levels of Phosphorus and Sulphur on Seed & Stover Yield of Soybean (Glycine max L. Merill) under ‘Eutrochrepts’
Journal Title: Asian Research Journal of Agriculture - Year 2017, Vol 5, Issue 1
Abstract
A field experiment was conducted at KVK, Srinagar during two consecutive kharif seasons of 2010 and 2011 to study the “Effect of phosphorus and sulphur on yield and quality of soybean (Glycine max L. Merill) under Eutrochrepts”. The experiment was laid down under 16 treatment combinations viz four levels of phosphorus (0, 30, 60, 90 kg P2O5 ha-1) and four levels of sulphur (0,15, 30, 45 kg S ha-1) in randomized complete block design with three replications .The soil of the experimental site was typic Eutrochrepts, silty clay loam in texture having pH 7.18, EC 0.18 dSm-1, organic carbon 0.74 per cent, available N, P, K 250.52, 11.45, 120.62, kg ha-1, respectively. Soil was sufficient in available Fe, Cu, Mn and deficient in available Zn and sulphur. Total and organic phosphorus content in soil was 345 and 173 ppm, respectively while as total and organic sulphur content was 232 and 162 ppm, respectively. Both seed and stover yield of soybean increased significantly due to individual as well as combined application of phosphorus and sulphur. Combined application of 45 kg S with 90 kg P2O5 produced highest seed (24.39 q ha-1) and stover (43.51 q ha-1) yield of soybean. Application of increasing levels of both phosphorus and sulphur resulted in a significant increase in macro and micronutrient content of soybean seed. With application of 90 kg P2O5 ha-1, maximum nutrient content of N, P, K, Ca, Mg and S in seed was 6.42, 0.56, 1.876, 0.324 0.440, 0.466 per cent, respectively while as Fe, Cu, Mn was 100.01, 2.86 and 3.74 mg kg-1, respectively.
