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%
