Evaluation of private sector maize genotypes (Zea mays L.) under agro-climatic condition of Prayagraj, U.P

Abstract

Maize (Zea mays L.) stands out as a highly adaptable crop, in diverse Agro-climatic conditions. It is known as Queen of cereals on a global scale due to its exceptional genetic yield potential compared to other cereals. Determining the optimal genotype among maize hybrids is crucial for enhancing productivity and meeting agricultural demands. A field experiment was conducted during Kharif season of 2023 at Crop Research Farm (CRF), Department of Agronomy, SHUATS, Prayagraj (UP) to investigate the “Evaluation of Private Sector Maize Genotypes (Zea mays L.) under Agro-climatic condition of Prayagraj, U.P.” The treatments consist of 07 hybrids. The 7 hybrids are UM-10, UM-20, UM-30, UM-40, UM-50, UM-60, UM-70. The experiment was laid out in Randomized Block Design with seven hybrids and replicated thrice. The significantly highest plant height (172.07 cm), no. of leaves/plant (12.30) plant dry weight (183.30 g/plant), crop growth rate (7.35 g/m2/day), seed index (30.45g), seed yield (8.76 t/ha) and harvest index (38.09%) were significantly higher in UM -20. In other hand UM -60 taking minimum time for Days to tasselling (46 DAS) and Days to silking (50 DAS), in UM -70 Days to maturity was recorded earliest (86.66 DAS).
