Effect of nitrogen level on yield attributes of aromatic rice

Field experiments were conducted during wet seasons of 2005 and 2006 at the Crop Research Station, Masodha, Faizabad, Uttar Pradesh in split plot design having three nitrogen levels (30, 60 and 90 kg N ha-1) in main plots and four aromatic rice varieties (IET – 17566, Badshahbhog, Kalanamak and Kanakjeer as local check) in sub plots to find out the suitable variety and optimum levels of nitrogen were evaluated for maximum grain yield under irrigated ecosystem. It was observed that IET- 17566 gave significantly higher grain yield (3.64 t ha-1). The Kalanamk and Badshah bhog were at par (4.04 and 3.06t ha-1). The graded levels of nitrogen significantly increased grain yield and all the attributing characters upto 60 kg N ha-1 (3.37 t ha-1). The N response at 60 and 90 kg N ha-1 (12.33 and 8.66 t ha-1) was higher over the mean grain yield at 30 kg N ha-1.
