Abstract:
A field experiment was conducted during kharif season (2021) at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P.). The soil of experimental plot was sandy loam in texture, nearly natural in soil reaction (pH 7.1), low in organic carbon (0.28%), available N (225 kg/ha), available P (19.50 kg/ha) and available K (213.7 kg/ha). The Treatments are 1.GA₃ 25 ppm + B₁ 1 kg/ha, 2.GA₃ 25 ppm + B₂ 2kg/ha, 3.GA₃ 25 ppm + B₃ 3 kg/ha, 4.IAA 50 ppm + B₁ 1 kg/ha, 5.IAA 50 ppm + B₂ 2kg/ha, 6.IAA 50 ppm + B₃ 3 kg/ha, 7.NAA 75 ppm + B₁ 1 kg/ha, 8.NAA 75 ppm + B₂ 2 kg/ha, 9.NAA 75 ppm + B₃ 3 kg/ha. The experiment was laid out in Randomized Block Design with 9 treatments and replicated thrice. The results reported that the application of GA₃ 25 ppm + B₃ 3 kg/ha recorded maximum plant height (70.10 cm), Number of tillers/plant (15.07), plant dry weight (23.60 g/plant), number of panicle per meter (692.00), panicle length (32.60 cm), number of panicle per hill (10.10), test weight (29.3 g), number of grains per panicle (158.10), Seed yield (3.60 t/ha), stover yield (4.10 t/ha). Maximum Gross returns (89143.30 INR/ha), Net returns(54928.33INR/ha) and B:C ratio (1.60) was recorded maximum in the treatment with the application GA₃ 25 ppm + B₃ 3 kg/ha.
