The present investigation was conducted during kharif season of 2014 at N.E. Borlaug Crop Research Centre of G.B. Pant University of Agriculture and Technology, Pantnagar (Uttarakhand) to optimizing the seed rate of hybrid and high yielding varieties of rice under direct seeded aerobic condition. Treatments were tested in a split plot design with three replications keeping varieties in main-plots and seed rates in sub-plots. Hybrid varieties DRRH 3 and PAC 837 performed better with the grain yields of 4620 kg/ha and 4554 kg/ha respectively as compared to high yielding varieties of PD 16 (4408 kg/ha). Among the different seed rates tested, seed rate of 35 kg/ha yielded more (4829 kg/ha) as compared to other seed rates. More yield and profit from direct seeded aerobic rice can be obtained from hybrid rice varieties with seed rate of 35 kg/ha under tarai condition of Uttarakhand, India.

Keywords: Aerobic rice, Sterility,Seed rate,Variety.
