Effect of accelerated ageing and dry dressing with botanicals on seed quality of soybean
The laboratory study on accelerated ageing of soybean seeds were evaluated for seed quality parameters. After five days of accelerated ageing soybean seeds were treated with fenugreek seed powder, ashwagandha, tea and noni leaf powder for 60 min @ 2 g kg-1 and evaluated for seed quality parameters. After five days of ageing germination came down to 65 % with reduced seedling length (cm), dry matter of seedling (mg 10 seedlings-1) and vigour index. Aged seeds of soybean treated with fenugreek seed powder @ 2 g kg-1 of seeds (ball milling for 1 h with 60 min shaking) recorded higher values for physiological parameters. The per cent gain over control was 19 (seedling emergence speed), 9.7(seedling emergence %), 37.5 (root length), 29.0 (shoot length), 18.1 (dry matter of seedlings) and 38.8(vigour of the seedlings).
