Abstract:
A field experiment was conducted during Rabi season (2021-2022) at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (Allahabad) (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 Nitrogen N1 (60 kg/ha.), N2 (80 kg/ha.), N3 (100 kg/ha.) 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 revealed that the application of Nitrogen 100 kg/ha. + Zinc 15 kg/ha. recorded maximum plant height (188.10 cm), Number of branches/plant (10.90), plant dry weight (26.38 g/plant), siliqua length (5.20 cm), number of siliquae per plant (398.90), number of seeds per siliqua (24.40), test weight (3.53 g), grain yield (1.89 t/ha.), straw yield (3.11 t/ha) and harvest index was found to be non-significant. Maximum Gross returns (103650.00 INR/ha.), Net returns (70264.08 INR/ha.) and B:C ratio (2.10) Where also recorded with the treatment with the application of Nitrogen 100 kg/ha. + Zinc 15 kg/ha.
