Abstract:

A field experiment was conducted during kharif 2006 and 2007 at crop research center, Meerut comprising combination of three levels of nitrogen (viz. 90, 120 and 150 kg N ha-1) and four methods of nitrogen application (viz. basal, at tillering and at PI; basal, at tillering and at PI; each at basal, tillering, PI and flowering; at tillering, at PI and flowering) in green manured wetland rice field. The experiment was laid down in Randomized Block Design with three replications. The grain yield of rice was highest with 120 kg N ha-1 (47.82 q/ha), which was statistically at par with 150 kg N ha-1 (49.71 q ha-1) and among different methods of nitrogen application, basal, at tillering and at PI it was recorded 49.76 q ha-1. In general, nitrogen application up to 120 kg N ha-1 in green manured wetland rice field had significant effect on growth characters (viz. plant height, shoot numbers and dry matter accumulation), yield attributes, yield and N-uptake. The above character recorded maximum values with nitrogen application as basal, at tillering and at PI followed by nitrogen application as basal, at tillering and at PI stages. In the light of above findings it can be concluded that nitrogen application of 120 kg N ha-1 applied in three splits as basal, at tillering and at PI stage in green manured wetland rice field is beneficial for rice crop.
