Abstract:
The objective of the study was to standardize the plant growth regulators doses with the effect of Salicylic acid (400 ppm), KNO3 and Salicylic acid (800 ppm) were positive effect on yield and yield contributing traits like number of tillers per plant, number of spikes per plant, spikelets per spike, 1000 seed weight and seed yield per plant (g) both of the varieties PBW-373 and NW-5054 were evaluated following 9 quantitative parameters viz., Days to 50% flowering, Days to maturity, Plant height (cm), Number of tillers per plant, Length of spike (cm), Number of spike per plant, Number of spikelets per spike, 1000 seed weight and Seed yield per plant (g). The maximum number of tillers per plant of Salicylic acid @ 400 ppm (8.88) followed by KNO3 @ 100 ppm (7.51), Salicylic acid @ 800 ppm (7.22), KCl @ 1% (6.79), Ascorbic acid @ 10 ppm (6.76), GA3 @ 100 ppm (6.66),, IAA @ 100 ppm (6.32), NAA @ 100 ppm (6.16) and Thiourea @ 400 ppm (6.10) as compared to control (4.97) during 2018-19 mean both of the varieties and maximum number of tillers per plant of Salicylic acid @ 400 ppm (8.74) followed by KNO3 @ 100 ppm (7.82), Salicylic acid @ 800 ppm (7.42), KCl @ 1% (7.10), Ascorbic acid @ 10 ppm (6.63), GA3 @ 100 ppm (6.66), IAA @ 100 ppm (6.32), NAA @ 100 ppm (6.11) and Thiourea @ 400 ppm (5.51) as compared to control (4.82) during 2019-20 mean both of the varieties and maximum seed yield per plant (g) of Salicylic acid @ 400 ppm (11.47) followed by KNO3 @ 100 ppm (10.74), Salicylic acid @ 800 ppm (10.16), KCl @ 1% (9.61), Ascorbic acid @ 10 ppm (9.57), GA3 @ 100 ppm (9.25), NAA @ 100 ppm (9.13), Thiourea @ 400 ppm (9.03) and IAA @ 100 ppm (8.88) as compared to control (8.33) during 2018-19 mean both of the varieties and maximum seed yield per plant (g) of Salicylic acid @ 400 ppm (11.24) followed by KNO3 @ 100 ppm (10.47), Salicylic acid @ 800 ppm (10.01), KCl @ 1% (9.59), Ascorbic acid @ 10 ppm (9.54), GA3 @ 100 ppm (9.26), NAA @ 100 ppm (9.12), Thiourea @ 400 ppm (8.79) and IAA @ 100 ppm (8.30) as compared to control (7.91) during 2019-20 mean both of the varieties was noticed.
