Abstract:
The present investigation was carried out with the objective on evaluation of treated and untreated seeds of soybean with different seed moisture contents for seed quality parameters viz., germination, seedling vigour index and electrical conductivity following accelerated ageing. Soybean seeds with 7%, 9%, 11% and 13% were treated with a combination fungicide Carboxin 37.5% + Thiram 37.5% (Vitavax power) @ 3g/kg seed and were subjected to accelerated ageing at 24, 48, 72 and 96 hours along with their respective untreated seeds. Among the moisture contents and across the ageing periods, the highest germination was recorded after 24 hours ageing in treated seeds of 7% moisture content (62.75%), while the lowest was observed in untreated seeds of 13% moisture content (53%). However, the treated seeds with high moisture content of 11% were found practically approximate and performed close to the untreated seeds with low moisture content (7 and 9%) even after accelerated ageing and thus it is concluded that drying can be avoided by opting seed treatment of seeds with 11% moisture content.
