Abstract:
The experiment was conducted at the Horticulture Farm of Sher-e-Bangla
Agricultural University, Dhaka during the period from April to August 2012.
BARI Dherosh-1 was used as test crop in this experiment. The experiment
consisted of two factors viz., Nitrogen fertilizer as N
130 kg N/ha; and Phosphorus fertilizer as P

Block Design with three replications. All the parameters were significantly
influenced by different levels of nitrogen and phosphorus. Due to the effect of
nitrogen, the
highest yield (16.40 t/ha) was observed from N
and the lowest yield
(12.30 t/ha) from N

. In case of phosphorus, the highest yield (16.95 t/ha) was
found from P

and the lowest yield (11.20 t/ha) from P
. For combined effect, the
highest yield (19.76 t/ha) was found from N

. From growth and yield and also economic point of view,
it is apparent that the combination of N
