Effect of Pre-Sowing and Invigoration Treatment for Better Crop Establishment of Mungbean

Rao PS, Ankaiah R, Gopal Reddy B

Abstract: A study was conducted to evaluate the possibility of integration of different pre-sowing seed treatments with an objective to ensure rapid and uniform field emergence under a wide range of adverse conditions. Fresh and revalidated seed lots of mungbean cv WGG 37 were subjected to invigoration with Hydration (2 h) and drying at RT, 2 % CaCl2 and surface drying, Hydration with GA3 @ 50 ppm and surface drying, Hydration and drying followed by dry dressing with Thiram @ 0.25 %, 0.5 % KNO3 hydration and drying and untreated control, as pre sowing treatment. Seed invigoration with Hydration and drying followed by dry dressing with Thiram @ 0.25 % before sowing was found very effective for crop establishment with vigorous seedlings, per cent increase seed germination over control, final stand, field emergence index and finally seed yield. A positive interaction between mean germination, vigour, final stand and seed yield indicated long-term effects of seed invigoration on plant growth and development. The present results clearly demonstrate that the seed quality and crop productivity of revalidated seed lots can be improved by pre-sowing and invigoration treatments.
