Influence of soil applied sulfur and boron on yield and quality parameters of soybean.

摘要

A greenhouse experiment was conducted in north-west India to study the influence of sulfur and boron addition to soybean in sulfur and boron deficient soil on yield and its quality parameters at different growth stages (55 days and maturity). The treatments included four levels each of soil applied sulfur viz., 0, 6.5, 13.4, 20.1 mg S/kg and boron viz., 0, 0.22, 0.44, 0.88 mg/kg at the time of sowing. The highest dry matter yield at 55 days after sowing (DAS) (19.3 g/pot) and maturity (straw yield -25.2 g/pot and grain yield -7.3 g/pot) was recorded with B_0.44S_13.4 treatment. The combined application of sulfur and boron yielded highest oil content with B_0.44S_13.4 (21.7%) application. Chlorophyll 'a' and 'b' increased significantly with successive levels of sulfur addition at 55 DAS.
