Abstract:

A field experiment was carried out in experimental farm of Bihar Agricultural University, Bhagalpur during the rabi season of 2014-15 to test the effect of synthetic compounds on performance of wheat under high temperature stress condition. Treatments were laid out in split plot design with three replications. Two contrasting varieties of wheat, i.e. DBW-14 (timely sown) and K 307 (late sown) were kept in main plots. Each main plot was further sub-divided into fourteen subplots which received foliar spray of different synthetic compounds either at a fixed dose at booting or at anthesis stage or half the fixed dose at both booting and anthesis stage. The foliar spray were as follows: M1- no spray, M2- KNO3 (1.0 %) at booting stage, M3- KNO3 (1.0 %) at anthesis stage, M4- KNO3 (0.5 %) both at booting and anthesis stage, M5- CaCl2 (0.2%) at booting stage, M6- CaCl2 (0.2%) at anthesis stage, M7- CaCl2 (0.1%) both at booting and anthesis stage, M8- Glycinebetaine (100 mM) at booting stage, M9- Glycinebetaine (100 mM) at anthesis stage, M10- Glycinebetaine (50mM) both at booting and anthesis stage, M11- Arginine (2.5mM) at booting stage, M12- Arginine (2.5mM) at anthesis stage, M13- Arginine (1.25mM) both at booting and anthesis stage and M14-spray of water both at heading and anthesis stage. Result shows that grain yield was increased significantly and maximized (36.96 and 31.23 qha-1 for V1 and V2 respectively) when the crop received foliar spray of KNO3 at the rate of 0.5% both during booting and anthesis stage over no foliar spray. The corresponding values with the foliar spray of CaCl2 showed same trend like KNO3 and were found to be statistically at par. Economic analysis revealed that the foliar spray of KNO3 at the rate of 0.5% both during booting and anthesis in DBW-14 significantly increased and maximized B: C ratio (1.9) over control but did not respond significantly in K 307. Thus, the study suggests that foliar spray of KNO3 at the rate of 0.5% both during booting and anthesis in a short duration variety like DBW-14 is beneficial to mitigate the ill effects of high temperature stress and enhance the yield to a profitable limit.
