Abstract

The growth, yield and yield attributing characters of Sabitri rice variety was evaluated under different age and number of seedlings hill^-1 at Dang, Nepal during rainy season from June to September, 2018. The experiment was laid out in to split plot design of three different age of seedlings as viz. 22 days, 29 days and 36 days as main plot factor and four number of seedling hill^-1 viz. 2, 3, 4 and 5 as sub-plot factor and replicate thrice. The results revealed that the highest plant height (122.8 cm) at the time of harvesting, longest panicle length (25.3 cm) and number of sterile grain panicle^-1 (26.0) was recorded by 22 days old seedlings. The highest number of effective tiller m^-2 (285) and highest grain yield (4.0 t ha^-1) was recorded by 29 days old seedlings. Whereas thousand grain weight and harvest index were non-significant with different age of seedlings. Regarding the number of seedlings hill^-1 highest number of effective tiller m^-2 (296), longest panicle (24.9 cm), grain yield (4.2 t ha^-1) and straw yield (6.1 t ha^-1) was recorded from the 4 number of seedlings hill^-1. Highest sterile grain panicle^-1 was recorded in 5 number of seedlings hill^-1 and highest harvest index (41.0%) was obtained from 3 seedlings hill^-1. The plant height at the time of harvesting, filled grain panicle^-1 and thousand grain weight were non-significant with number of seedlings hill^-1. The interaction effect of age and number of seedlings hill^-1 showed non-significant relation with all the growth, yield and yield attributing parameters.
