Abstract:
Field experiment was conducted to evaluate the effect of different transplanting dates, seedling rates and spacings on yield and economics of hybrid in Selaqui, Dehradun (Uttarakhand), at the Crop Research Farm, Department of Agronomy, Maya College of Agriculture and Technology, during the 2016 kharif season. Experiment comprised 18 treatments, including 3 transplanting dates (15 July, 27 July, and 09 August), 2 seedling rates (1 seedling hill^-1 and 2 seedling hill^-1) and 3 spacings (20 X 10 cm, 20 X 15 cm and 20 X 20 cm). The experiment was replicated three times and using a randomized block design. The test crop was rice of the "Arize 6444 variety". Results revealed that hybrid rice transplanted at 15 July with 20 x 20 cm spacing and 2 seedlings hill^-1 proved to be the best for obtaining maximum grain (64.33 q ha^-1), straw (80.67 q ha^-1) and biological yield [145.00 q ha^-1) and returns (gross (₹ 93330 ha-1), net returns (₹ 42514 ha-1) and B:C ratio (1.83)].
