Evaluation of growth and yield of maize (Zea mays L.) hybrids under agro-climatic conditions of Prayagraj, U.P.

A field experiment was conducted during kharif season of 2020 at experimental field of the Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj, (UP) to determine the “Response on growth and yield of Maize (Zea mays L.) Hybrids under agro-climatic conditions of Prayagraj, U.P”. The soil of 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. Full dose of phosphorus and potassium fertilizers were applied as basal while, half of nitrogen was applied as basal and remaining half was applied 25, 45 days after sowing. Report of study indicate that, among different Hybrids KM-19 produced significantly higher plant height (222.30 cm), number of leaves per plant (11.47), dry weight/plant (77 g), CGR (0.83 g/m2/day), number of cobs per plant (1.78), number of rows per cob (13.97), number of grains per row (26), seed index (27.33g), Seed yield (7.08 t/ha) and stover yield (21.1t/ha). However, the Hybrid KM-19 also showed significantly minimum number of days to 50% Tasselling (43.40 days), 50% silking (47.07 days), and days to maturity (65.67).
