Abstract:
The present investigation entitled “Influence of plant growth regulators on growth and yield of wheat (Triticum aestivum L.) Under late sown condition” has been taken to focus the involvement and potential role of plant growth regulator and was carried out in during 2019-20 and 2020-21 at Agronomy Research Farm of C.S.A. University of Agriculture and Technology, Kanpur (U.P.). The experiment was done during Rabi (2019-20 and 2020-21) using wheat variety K-9423 using randomized block design having eleven treatments and three replications having thirty-three plots different plant growth regulators are used at various growth stages for overall development of crop. The details of the following treatments used for two years of experimentation is as follows T1: Control, T2: IAA, 25 ppm T3: IAA, 50 ppm T4: Abscisic acid 10 ppm, T5: Abscisic acid 20 ppm, T6: TRIA 5 ppm, T7: TRIA 10 ppm, T8:B rassinosteroid 5 ppm, T9: Brassinosteroid 10 ppm, T10: Cytokinin 5 ppm, T11: Cytokinin 10 ppm. Foliar spraying at two stages - first at 30 DAS (Vegetative stage) and second at anthesis in uniform dose of all treatments. The maximum Grain Yield in wheat was observed in T3 (3965.00) and (4065.00) with application of IAA 50 PPM which was significantly superior over T11 (3815.00) and (3918.00) which was statistically at par with T2 (3705.00) and (3813.00), T10 (3595.00) and (3719.00), T9 (3475.00) and (3584.00) and T8 (3405.00) and (3480.00).
