Role of Organic Fertilizers on Morphological and Yield Parameters in Rice; Oryza sativa L

In order to study the role of organic fertilizers on morphological and yield parameters in rice, an experiment was carried out in years 2008 and 2009, in randomized block design based on 4 replications. Cow manure, poultry manure, rice straw and rice 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. An increase in the grain yield may be due to the increase Parameters like dry matter, total number of tiller, flag leaf length, number of fertile tillers per hill and 1000-seed weight.
