tailieunhanh - Growth and yield attributes of direct seeded aerobic rice (Oryza sativa L.) as influenced by seed rate and varieties

The present investigation was conducted during kharif season of 2014 at . Borlaug Crop Research Centre of . 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. | Growth and yield attributes of direct seeded aerobic rice Oryza sativa L. as influenced by seed rate and varieties
