Abstract:
A field experiment was conducted during kharif season of 2021 at Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology & Sciences, Prayagraj, Uttar Pradesh, India on soil with sandy loam in texture to study the “Evaluation of Maize (Zea mays L.) Hybrids under agroclimatic conditions of Prayagraj, U.P.”. The experiment consists of 10 Maize hybrids viz., UM-01, UM-02, UM-03, UM-04, UM-05, UM-06, UM-07, UM-08, UM-09, UM-10. The experiment was laid out in Randomized Block Design (RBD) with 10 hybrids replicated thrice. 50% of recommended dose of nitrogen was applied as basal application and remaining 50% was applied at 25 and 45 DAS. Full dose of phosphorus and potassium fertilizers were applied as basal application. The study revealed that, among different Hybrids UM-2 produced significantly higher plant height (216.79 cm), number of leaves per plant (12.74), dry weight/plant (159.88 g), number of cobs per plant (2.00), cob length (17.30), number of rows per cob (15.93), number of grains per row (33.36), Seed yield (6.98 t/ha) and stover yield (20.40 t/ha). The hybrid UM-2 recorded significantly minimum number of days to 50% Tasseling (45.67 days) and 50% silking (49.00 days). Hybrid UM-2 also fetched highest gross returns (1,85,606.00 INR/ha), net returns (1,32,911.00 INR/ha) and benefit cost ratio (2.52) when compared to other hybrids.
