An experiment was conducted at the Research Field of the Shcr-e-lIanda Aericultural ( Jniversitv,
Dhaka 1207 during the period horn July 2012 to December 2012 to stud the effect of' phosphorus
and potass i urn in the field regarding on growth. v icld and nutrients content of B RRI dhaii3 .3

application of K2Sth (a: 20 kg ha and 1<2: Foliar application ot' K1SO.1 â ID kg ha

replications where the nieuns were adjudged by DMR F at 5% level of probability. All the studied
traits were significantly affected by the singly or interaction ellèct of both P and K ICrtilizers except
