| dc.description.abstract | The study was conducted at BRAC maize research farm, Sherpur, Bogra during
November 2015 to April 2016 to investigate the influence of population density
on yield contributing characteristics of different maize varieties. The experiment
was carried out following two factors randomized complete block design with
three replications. The experimental treatments were four plant spacing (P1 =
75cm × 20 cm, P2 = 60 cm × 20 cm, P3 = 75 cm × 15cm and P4 = 50 cm × 20 cm)
and three maize varieties (V1= 981M, V2 = Biplob, V3 = Pacific-984). Almost all
the parameters recorded in the present study were not influenced significantly by
the interaction effect of plant population and maize varieties. Among the growth
and phenological parameters, plant height at 55 and 125 days after sowing (DAS),
cob height, leaves plant-1
and leaf area at 125 DAS, days to tasseling, days to
silking, days to anthesis-silking interval and days to maturity were significantly
influenced only by the maize varieties. Most of the yield contributing
characteristics i.e. cob length, cob diameter, cobs plant-1
, rows cob-1
, grains row-1
,
grains cob-1
, thousand grain weight and grain yield plant-1 were reduced with
increment of plant population but grain yield (t ha-1
) was increased with the
increment of plant population. Based on grain yield plant-1
and grain yield ha-1
maize variety 981 M performed the best followed by maize variety Biplob and
Pacific-984. | en_US |
