The material comprised of a variety “HFP-529” which was grown in the research farm of Department of Seed Science & Technology with twenty three treatment combinations of organic manures, inorganic fertilizers and biofertilizers. All the treatments were assessed for different seed yield, quality and storability parameters. Among the treatments, Rhizobium+PSB+100% recommended dose of nitrogen exhibited better performance in terms of yield and its attributes as compared to control. It was observed that application of Rhizobium+PSB+100% nitrogen followed by Rhizobium+PSB+75% nitrogen had maximum vigour potential in terms of test weight, seed density, standard germination, seedling length, seedling dry weight, vigour index, lower electrical conductivity as compared to control. The higher antioxidant enzyme activities (CAT, POD, SOD and dehydrogenase) were recorded in the treatment combination of Rhizobium+PSB+100% nitrogen followed by Rhizobium+PSB+75% nitrogen in comparison to rest of treatments. Nutrient combination of Rhizobium+PSB+100% nitrogen showed maximum speed of emergence, seedling establishment and minimum mean emergence time. Seeds of all the treatment combinations were stored for fifteen months in plastic bags and seed quality was evaluated after five, ten and fifteen month’s interval. It was noticed that seed vigour and quality was negatively affected during storage. Though all the treatments showed decline in vigour but less decline was recorded in the treatment Rhizobium+PSB+100% nitrogen as compared to other treatments after fifteen months of storage. After estimating antioxidant enzyme activities it was found that there activities were declined during ambient storage, however the maximum activity after fifteen months of storage was recorded in the treatment Rhizobium+PSB+100% nitrogen. The freshly harvested seeds of all the treatments were subjected to artificial ageing at 40±1 °C for 72 h and were again assessed for seed quality and antioxidant enzyme activities. After artificial ageing it was noticed that treatment combination of Rhizobium+PSB+100% nitrogen followed by Rhizobium+PSB+75% nitrogen showed better performance in all the seed quality parameters and maximum antioxidant enzyme activities in comparison to other treatments.ennullThesis
