Effect of sources and levels of sulphur on seed yield, quality and sulphur uptake by soybean, Glycine max (L.) Merrill.

摘要

Soybean, Glycine max (L.) Merrill is basically a leguminous crop and is gaining importance as an oilseed crops. Soybean is of paramount importance in human and animal nutrition, because it is a major source of edible vegetable oil and high protein. Sulphur is one of the essential plant nutrient, its importance in Indian agriculture is being increasingly emphasized. Role of sulphur in crop production particularly in oilseeds and pulses has been reported by several research workers. Sulphur deficiencycauses 12-15% reduction in seed yield of soybean (Chandel ef al., 1989). Optimum dose of sulphur application with efficient source may be the remedial measure to improve the soybean yield and quality. With these considerations in view, the present studywas undertaken to know the effect of sources and levels of sulphur on seed yield, quality and sulphur uptake by soybean on deep black soil of Marathwada region.
