Influence of physical seed treatment on seed quality improvement in black gram (Vigna mungo L.)
Article Main
Abstract
Pelleting is a physical pre-sowing seed management technique, in which seeds are enclosed with biopromotive substances to improve the field stand. To evaluate the efficacy of plant herbal powders for seed pelleting, studies were initiated with blackgram cv. ADT 3, in which seeds were pelleted with the leaf powders of noni (Morinda citrifolia) and basil (Ocimum sanctum) and fruit powder of gallnut (Terminalia chebula) @ 200 g kg-1 of seed using Carboxy methyl cellulose @ 200 ml per kilogram of seed as an adhesive. The results revealed that seeds pelleted with the leaf powders of either basil improved the seed germination by 6% and seedling vigour (23%), seedling length (9%) and seedling dry weight (5%). In raised bed nursery, the seeds pelleted with basil leaf powder @ 200 g kg-1 of seed recorded improved field emergence (7%) with higher chlorophyll index (30%) and nodule number (28%) highlighting the efficacy of the treatment. While, the seeds pelleted with gallnut fruit powder recorded lowest germination, vigour and field emergence which is significantly lesser than control. The delayed emergence, germination and vigour was due to the increase in hardiness of gallnut powder pelleted seed. Thus, the seeds treated with basil leaf powder @ 200 g kg-1 using carboxy methyl cellulose @ 200 ml per kilogram of seed as an adhesive, enhanced seed germination, vigour, seedling length and dry weight.
