Abstract
A field experiment was conducted during the kharif season of 2021 at experimental field of the Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology & Sciences, Prayagraj, and Uttar Pradesh, India to determine the Growth and Yield of Maize (Zea mays L.) Hybrids Under Agro-Climatic Conditions of Prayagraj, Uttar Pradesh, India. The experiment was done on 15 Maize Hybrids. It was carried out through a statistical design of Randomized Block Design (RBD) with three replications. The soil of the experimental plot was sandy loam in texture and contain pH 7.8, organic carbon (0.35%), available nitrogen (243kg/ha), available phosphorus (20.10kg/ha) and available potassium (105 kg/ha).Report of study indicate that, among different Hybrids UM-14 produced significantly higher plant height (218.48 cm), number of leaves per plant (13.07), dry weight/plant (166.11 g), cob length (17.12 cm), number of cobs per plant (2.07), number of rows per cob (15.60), number of grains per row (31.10), Seed yield (7.99 t/ha), stover yield (18.95 t/ha) and harvest index (29.67%). Hybrid UM-14 also fetched highest gross returns (Rs.2,00,631/ha), net returns (Rs.1,43,736/ha) and benefit cost ratio (2.53) when compared to other Hybrids in both growth and yield attributes.
