Languages : English (eng) Keywords: rice hybrids ; productive tillers grain yield panicle length Abstract: Four rice hybrids were evaluated for yield and yield attributing traits at National Rice
Research Program, Hardinath , Dhanusha in comparison to Chaite-2 and Hardinath-1 during
spring season, 2011. The experiment was conducted in randomized complete block design
with three replications. Out of four tested hybrids two hybrids viz., V -775 and 834 produced
more productive tillers/m2
, longer panicles and higher grain yield (kg/ha) than the check
varieties Chaite-2 and Hardianth-1. The increase in yield over the checks; Chaite-2 and
Hardinath-1 ranged from 20.33-48.13% and 16.73-43.70%, respectively. While the other two
hybrids, Arize 6129 and 813 produced lower grain yield (kg/ha) than the checks.Link for e-copy: http://elibrary.narc.gov.np/?r=885 Performance of rice hybrids in spring season in Dhanusha district [printed text] / Dil Raj Yadav ; Ram Baran Yadaw, Author ; Surya Narayan Sah, Author ; Umesh Sah, Author ; Parmananda Sharma, Author ; Dilip Sah, Author . - [s.d.] . - 172-173 p.
