Abstract

A trial was carried out during the Kharif season 2020 at the experimental plot of Crop Research Farm, which was located near the department of Agronomy, SHUATS, Prayagraj, (U.P.). The Soil of the experimental site was sandy loam in texture, nearly neutral in soil reaction. The experiment consists of different Hybrids viz., KM-11, KM-12, KM-13, KM-14, KM-15, KM-16, KM-17, KM-18, KM-19, KM-20, and KM-21. It was carried out through a statistical design of Randomized Block Design (RBD) with three replications. A Full dose of phosphorus and potassium fertilizers were applied as basal while, half of the nitrogen was applied as basal and the remaining half was applied 25, 45 days after sowing. Report of the study indicates among different Hybrids KM-19 produced significantly higher plant height (213.50 cm), number of leaves/plant (11.87), and dry weight/plant (75 g). Hybrid KM-19 also fetched the highest gross returns (1, 83,614.17 INR/ha), net returns (1, 33,454.17 INR/ha), and benefit-cos

Conclusion

Among all hybrids, KM-19 was found to be the best by obtaining the highest growth and yield and also a better B: C ratio. It was found more productive, when compared to others under agroclimatic conditions of Prayagraj, U.P. The public sector hybrids need to be tested in different agro-climatic conditions as they possess genetic variation, to find out best-performing hybrids for their release in the market. KM-19 was found best in Prayagraj condition compared to others.
