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. ½ basal, ¼ at tillering and ¼ at PI; ¼ basal, ½ at tillering and ¼ at PI; ¼ each at basal,
tillering, PI and flowering; ½ at tillering, ¼ 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, ½ basal, ¼ at tillering and ¼ 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 ½ basal, ¼
at tillering and ¼ at PI followed by nitrogen application as ¼ basal, ½ at tillering and ¼ 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 ½
basal, ¼ at tillering and ¼ at PI stage in green manured wetland rice field is beneficial for rice crop.
