Abstract:
A field experiment entitled "Evaluation of growth, yield, and economics of maize (Zea mays L.) Hybrids under agro- climatic conditions of Prayagraj, U.P" 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-1, KM-2, KM-3, KM-4, KM-5, KM-6, KM-7, KM-8, KM-9 and KM-10. 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, half of the nitrogen was applied as basal and the remaining half was applied 45 days after sowing. Report of the study indicates among different Hybrids KM-8 produced significantly higher plant height (207.50 cm), number of leaves/plant (11.80), and dry weight/plant (75.20 g). Hybrid KM-8 also fetched the highest gross returns (1, 95,015.00 INR/ha), net returns (1,44,855.00 INR/ha), and benefit-cost ratio (2:88) when compared to other Hybrids. Due to genetic variation among the hybrids different challenges were experienced during the research. They had germinated and matured differently. Also, disease and pest attacks were quite varied in hybrids.
