Abstract:
An experiment was conducted at the Agronomy Farm of Sher-e-Bangla Agricultural
University, Dhaka during November 2019 to April 2020 to examine the response of
local maize varieties to different doses of fertilizer application. The experiment
comprised of two doses of fertilizer (viz. 100% and 50% of the recommended for the
composite varieties designed as F
100
and F
) and eight local maize varieties named
according to the grain colour (White, Yellowish, Yellow, Reddish, Red, Blackish-red,
Black-bold, and Black-small). The experiment was laid out in Split Plot Design with
three replications. The main plot was used for fertilizer doses and sub plot was used
for varieties. Data was taken on plant height, no of leaves plant

yield and harvest index. The fertilizers and varieties showed significant differences in
almost all the plant parameters. The fertilizer treatments did not show significant
difference in terms of grain yields. The variety yellowish, yellow and blackish-red
showed statistically similar grain yields (5.2-5.46 t ha

). Likewise, the interaction of
fertilizer and variety had significant differences. The interaction of F
with the
varieties White, Yellowish, Yellow, Reddish and Red showed seed yields which were
at par but significantly higher over others showing the range between (5.300-5.500 t

). The lowest grain yield was obtained with F
100
Black-small (3.40 t ha
