Evaluation of Maize Hybrids under Rainfed Condition in New Alluvial Zone of West Bengal

Abstract

At Bidhan Chandra Krishi Viswavidyalaya's District Seed Farm (AB-Block), Kalyani during the 2020 kharif season, a experiment in the field was taken to study the performance of maize hybrids and to study crop yield and adaptability of maize hybrids. Four replications of the experiment were conducted using a Randomized Block Design and six maize hybrids (DKC 9144, DKC 7204, DKC 8181, P3396, Kaveri 50 and Yuvraj). The experiment's findings showed that the maize hybrid DKC 9144 recorded the highest growth attribute like plant height (252.67 cm) and characters related to yield attributing include 100 seed weight (41.67 g), grains row -1 (43.00) and grain rows cob -1 (13.97). Highest grain yield (9.06 t ha -1 ), stover yield (10.99 t ha -1 ) and harvest index (47.80) were obtained by maize hybrid DKC 9144 than other maize hybrids. Lowest growth character (plant height), yield attributing characters (Grain rows cob -1 , Grains row -1 and 100 seed weight), yields (Grain yield and Stover yield) and harvest index of maize were recorded by Kaveri 50 hybrid. According to the experimental findings, cultivating the hybrid maize variety DKC 9144 under rainfed conditions in new alluvial zone of West Bengal is advised in order to maximise the output of farmers.
