Field experiment conducted at Regional Research Station (SKUAST-K), Wadura, Kashmir to study the influence of integration of foliar spray of free-living diazotrophs and boron with N on yield, nutrient uptake and N economy of rice for two consecutive years. Application of 100% N+boron recorded maximum grain yield (6.72 t/ha), additional net income (‘18, 902/ha), total N uptake (107.54 kg/ha), total B uptake (50.8 g/ha) and N use efficiency indices. Application of 100% N+boron registered higher grain and straw yield by 3.70 and 2.69% over 100% alone. Further, application of 50% N (two split) at 15 and 30 DAT+Azotobacter+boron being on par with 100% N had considerably higher grain and straw yield over 50% N (one split at 30 DAT)+Azotobacter+boron and 50% N (one split at 30 DAT)+Azospirillum+boron. Foliar spray of Azotobacter was more effective over Azospirillum, which enhanced grain yield by 2.21-3.42% irrespective of N splitting. Under temperate conditions of Kashmir valley higher grain yield, profitability and N use indices viz. physiological efficiency of N (20.2%), agronomic efficiency of N (27.1%), relative efficiency of N (58.9%) and factor productivity for applied N (84.0%) could be realized with the application of 100% Not Available |
