Evaluation of Upland Rice Varieties in Western Terai of Nepal

Abstract

: Sixteen rice varieties were collected from Banke, Bardiya, Kailali and Kapilvastu districts to select the superior varieties for upland rain-fed condition. These varieties were tested in RCBD with three replications in the years 2018 and 2019. The parameters compared were heading and maturity days from sowing, plant height, and number of tillers per square meter, grain and straw yield per hectare. Varieties were significantly different for all the traits studied. The variety earliest to head (84 days) and maturity (115 days) was Hardinath-1. Shortest plant height (99.8cm) was observed in Parssana and the longest (157.0 cm) in Sugapankhi. Maximum number of tillers/m 2 (319) was recorded in PH-6. Among the tested genotypes, Sampurna produced significantly higher grain yield (4628 kg/ha) followed by Sama (4320 kg/ha) and Prasanna (4208 kg/ha), while highest straw yield (9859 kg/ha) was obtained from Sugapankhi. The superior varieties will be used as reference variety to develop new varieties.
