Abstract

A field experiment was conducted during kharif 2020 at Krishi Vigyan Kendra, Kalyandurgam (A.P.). The soil of trial plot was sandy loam in texture, basic in soil reaction (pH 8.29), low in Organic carbon (0.20%), medium available N (170.6 kgha-1), higher available P (31.0 kg ha-1) and medium available K (232.5 kg ha-1). The research is laid out in Randomized Block Design (RBD) which consist of nine treatments replicated thrice. The outcomes showed that higher plant height (164.24 cm), maximum dry weight (27.69 g), higher Crop Growth Rate (4.46 g/m2/day) were noted significantly higher with the application of Nitrogen (N) 85 kg ha-1 + Zinc (Zn) 10 kg ha-1. The maximum no. of grains per ear head (1724.96), Number of effective tillers (1.61), grain yield (3.77 t ha-1), stover yield (5.96 t ha-1) then harvest index (39.45%) were noted significantly with the application of Nitrogen (N) 85 kg ha-1 + Zinc (Zn) 10 kg ha-1. The maximum net returns (81050.3 INR ha-1) then B:C (1.86) noted with

Keywords

Conclusion

On the basis of study, suggests that the application of Nitrogen (N) 85 kg/ha + Zinc (Zn) 10 kg/ha resulted highest grain yield of (3.77 t ha-1), net return (81050.3 INR/ha) as well as B:C ratio of (1.86).
