dc.description.abstractThe present investigation denominated “Response of greengram (Vigna radiata L.) to seed priming under rainfed condition” was executed at Regional Research Station, Bawal, CCSHAU, Hisar during Kharif, 2020. The experiment was conducted in randomized block design, replicated thrice, having nine treatment combination. For the seed treatment of one ha seed rate, 20 g of priming chemical was applied for individual treatment. Greengram is a drought hardy and short duration kharif annual legume crop. Seedling vigour, consistent germination, early seedling emergence, crop growth and development were all increased by priming chemicals. Seed priming with KH2PO4 @ 2% for 8 hours and 2 hours sun drying was the best priming method in context of phenology, growth characteristics, yield and yield attributes of greengram. Different priming treatments significantly influenced phenological characteristics of greengram. Minimum days taken to emergence, 50% flowering, pod initiation and physiological maturity were accomplished by seed priming with KH2PO4 @ 2% for 8 hours and 2 hours sun drying. Seed priming with KH2PO4 @ 2% for 8 hours and 2 hours sun drying has 86.67%, 74.23%, 59.9% and 33.09% higher dry weight per plant than control at 15, 30, 45 DAS and at harvest, respectively. Seed priming with KH2PO4 @ 2% for 8 hours and 2 hours sun drying had 50.73%, 53.63%, 35.30% and 15.56% higher number of branches/plant, number of pods/plant, number of seeds/pod, pod length and test weight. The N, P and K concentration (%) in seed and straw was not significantly influenced by different priming methods. NPK uptake in seed and straw was significantly swayed by different priming methods. Total NPK uptake in seed and straw was highest through seed priming with KH2PO4 @ 2% for 8 hours and 2 hours sun drying. Seed priming with KH2PO4 @ 2% for 8 hours and 2 hours sun drying had 15.49%, 15.43% and 10.18% higher uptake of nitrogen, phosphorous and potassium, respectively. Seed yield, straw yield and biological yield had significant proclivity towards different priming treatments. Maximum of all were with seed priming with KH2PO4 @ 2% for 8 hours and 2 hours sun drying which was statistically at par with hydropriming for 8 hours and thus the poor farmers should follow simple water soaking instead of chemical priming. Seed priming with KH2PO4 @ 2% for 8 hours and 2 hours sun drying recorded 10.94%, 9.38% and 9.84%, respectively higher seed yield, straw yield and biological yield than control. Highest gross return was observed through osmopriming with KH2PO4 @ 2% for 8 hours and 2 hours sun drying. Similarly, maximum net return and B:C were attained with osmopriming with KH2PO4 @ 2% for 8 hours and 2 hours sun drying.en_US
