Abstract
An investigation of on farm trial (OFT) conducted on farmer’s field during Rabi season 2016-17 & 2017-18 in Kishanganj district of Bihar for studies on ‘Effect of foliar application of potassium nitrate on late sown wheat in mitigating terminal heat stress’ revealed that the foliar application of 0.5 % KNO3 at booting and 0.5 % KNO3 at anthesis stage of wheat recorded higher grain yield (31.50 and 30.30 q/ha in 2016-17 and 2017-18 respectively) followed by foliar application of 1.0 % KNO3 only at anthesis stage of wheat (29.75 and 28.50 q/ha in 2016-17 and 2017-18 respectively) in comparison to wheat yield obtained under farmer practice of without any foliar application (28.50 and 25.50 q/ha in 2016-17 and 2017-18 respectively).The two spray of KNO3 0.5% at boot and anthesis stage on wheat showed the favorable effect on yield attributing characters(plant height, effective tillers/m2,spike length, number of grains/spike and test weight). This treatment also recorded higher net return and B:C ratio (Rs. 28,250/ha, 2.49) during 2016-17 and that (Rs. 24,450/ha, 2.27) during 2017-18 respectively. The application of KNO3 at the stage of booting and anthesis stage found effective in increasing the yield of late sown wheat variety HD-2985 in Kishanganj district of Bihar. Farmers were satisfied with the performance of the technology in mitigating heat stress in late sown wheat.
