Abstract:
An experiment was conducted at the Agronomy Field of Sher-e-I3angla Agricultural
University. Dhaka during December to March, 2007-2008 to investigate the response of
wheat cv. Shourav to different levels of nitrogen and plant spacing. The treatment
consisted of three nitrogen levels (120, 180 and 240 kg ha') and four plant spacing (3. 5.
7 andlO cm) in a row of 20 cm apart. The experiment was laid out in a split plot design
with three replications. Results revealed that nitrogen level and plant spacing influenced
plant towards higher yield either singly or in combination. Nitrogen at the rate of 180 kg
ha 4
perlonned maximum yield components and grain yield (3.46 t ha
4
). Almost similar
grain yield (3.76 t ha') was achieved at plant spacing of 20 em x 5 cm. The combined
effeci of nitrogen 180 kg ha'' along with 20 cm x 5 cm plant spacing produced greater
effective tillers plant"
(5.46), length of spike plant'' (12.07 cm). 1000-grain weight
(44.73 g) and grain yield (3.94
t ha''), which were positively supported by maximum
value othan•'est index (46.27%).
