Effect of integrated nutrient management on seed quality of vegetable soybean [Glycine max (L.) Merrill] cv. Karune

A laboratory experiment was conducted at the Department of Seed Science and Technology, GKVK, University of Agricultural Sciences, Bangalore. The results revealed that, application of recommended dose of NPK (30:80: 37.5 kg ha-1) + Recommended dose of FYM (10 t ha(-1)) +Brady rhizobium (250 g ha(-1))+PSB (250 g ha(-1)) significantly improved the seed quality parameters viz., 100 seed weight (35.51g), seed size (0.76 cm(3)), seed density (1.55 g/cc), total dehydrogenase activity (4.80), germination (92.00 %), seedling length (30.69 cm), seedling dry weight (90.75 mg), seedling vigour index- I and II (2820 and 836 respectively), protein content (36.30 %) and field emergence (89.33 %) with lowest electrical conductivity (0.49 mScm(-1)) as compared to control and other treatments. Further, artificially aged seeds through accelerated ageing method also recorded higher seed quality parameters in the same treatment at the end of six days of ageing period.
