Abstract:
The experiment was conducted in the Farm of Sher-e-Bangla Agricultural
University, Dhaka, Bangladesh during the period from July to November, 2013 to
study the effect of nitrogen and phosphorus on the growth and yield of BRRI
dhan38. The experiment comprised of two factors- Factor A: Levels of nitrogen
0
: 0 kg N ha
-1
i.e. control; N

: 45 kg N ha

showed the smallest plant
height in each case, respectively. Side by side, the highest number of effective
tillers per hill, highest length of panicle and the maximum number of filled grains
per panicle were found in N

was more potential in regarding yield contributing
characters and yield of BRRI dhan38.
