In order to study the effect of organic fertilizers on morphological parameters in rice, an experiment was carried out in 2010, in randomized block design based on 4 replications. Cow manure, poultry manure, rice straw and husk were used for formulation of organic fertilizers. The treatments of organic fertilizers CM, PM, CMR, PMR, and CPMR were used alone at 4t/ha in five treatments. Half dose of CPMR was used with half dose of RDF (N-50, P-25, K-25 kg/ha) at one level and RDF (N=100, P=50, K=50 kg/ha) alone at one level. The plants without treatments considered as control. Grain yield and morphological parameters were significantly increased in all the treatments over control. The maximum grain yield (4812.71 kg/ha) was noted in plants treated with CPMR 2t +½ RDF. An increase in the grain yield at the abovementioned treatments was may be due to the increase of dry matter, total number of tiller, flag leaf length, number of fertile tillers and 1000-seed weight.
