Abstract
An experiment was conducted at Sher-e-Bangla Agricultural University research
farm, Dhaka to study the effect of organic manure and inorganic fertilizers on the
growth and yield of maize during March to July 2019. Seeds of SAU hybrid vhutta 1
were used as planting material. The experiment was consisted of single factor and laid
out in Randomized Complete Block Design (RCBD) with three replications. There
were 11 treatments comprised with organic manure and inorganic fertilizers, They
were T

Results of the investigation revealed that, organic manure and inorganic fertilizers
showed significant effect on most of the growth, yield and yield contributing
characters of maize. The experimental result showed the maximum plant height at
harvest (268.43 cm), SPAD value at 60 DAS (62.865), dry matter weight at harvest
(296.60 g), cob to tassel length (137.98 cm), tassel length (20.490 cm), cob length
(46.10 cm), cob diameter (4.3433 cm), number of grain rows cob

(Vermicompost +

( Vermicompost + 75% of RDCF) showed statistically similar yield
and some yield characters with T
treatment. So it may be concluded that the
treatment T

(Poultry litter + 75% of RDCF) or treatment T
( Vermicompost + 75%
of RDCF) could be the best production package for achieving higher yield of maize.
