Abstract:
A field experiment was conducted during Rabi season (2021-22) 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 consisted of 3 levels of plant growth regulators PGR1 (GA3 30 ppm), PGR2 (GA3 60 ppm), PGR3 (GA3 90 ppm) and 3 levels of zinc (Zn1-5 kg/ha), (Zn2-10 kg/ha) and (Zn3-15 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 90 ppm + Zn 15 Kg/harecorded maximum (Treatment-9) Plant height (126.50 cm), Number of branches/plant (11.70), plant dry weight (14.50 g/plant), number of siliqua per plant (299.80), number of seeds per siliqua (23.20), test weight (3.23 g), seed yield (1.78 t/ha), straw yield (5.53 t/ha) and harvest index was found to be non-significant. Maximum Gross returns (95906.66 INR/ha), Net returns (57686.66 INR/ha) and B:C ratio (1.50) was recorded with the treatment (T9) with the application of GA3 90 ppm + Zn 15 Kg/ha.
