Abstract:
The field experiment was conducted during Rabi 2017-18 and the harvested seeds were kept under storage condition for study of seed quality parameters during 2018-19 at Seed Testing Laboratory, Department of Seed Science and Technology, Bidhan Chandra Krishi Viswavidyalaya, Mohanpur, Nadia, West Bengal. Seeds were treated with four concentrations of KNO₃ [viz. T1-0.5% of KNO₃, T2-0.25% of KNO₃, T3-0.1% of KNO₃, T0-hydrated seed (control)] and three durations of soaking [viz. D1-12 hours of soaking, D2-16 hours of soaking, D3-20 hours of soaking]. Treated seeds were sown in the field and replicated thrice. After harvest, seeds were kept under ambient storage condition and seed quality parameters were studied at three months interval up to next year of sowing. It was revealed that among the seed quality parameters T3D2 (0.1% of KNO₃+16 hours of soaking) showed maximum germination percentage (100%), seedling length (21.30 cm), Vigour index (2130) and minimum electrical conductivity (1.267mScm^-1) immediately after harvest and even nine months after storage.
