Abstract:
Present Study was conducted to access the comparative performance of sunflower to seed priming and nitrogen management during rabi 2021. Significantly higher germination percentage (91.3%), germination index (28.7), seedling vigour index (1954) and lowest time to 50% seedling emergence (3 days) was recorded under osmopriming with KNO₃ @ 0.1% (M₃). The lower germination percentage (88.2%), germination index (20.5), seedling vigour index (1282), plant population and highest time to 50% seedling emergence (4.67 days) was recorded in M₁ in control. Significantly higher plant population were recorded under osmopriming with KNO₃ @ 0.1% (M₃) Initial (101,407) and Final (100,518), lowest was recorded under control. Incase of nitrogen management practices highest was recorded under application with 150% RDN Initial (101,343) and final (100509). All the seedling establishment traits were significantly affected with osmopriming @0.1% KNO₃.
