Influence of applied nitrogen on grain yield, protein content and milling outturn in transplanted rice

Abstract

In an investigation conducted at the Rice Research Station, Pattambi using the early duration strain Thriveni as test variety, it was found th it application of a portion of nitrogen as top dressing at panicle initiation and booting stages increased grain yield, protein content and recovery of head rice. Protein content of grain and head rice recovery were observed to be closely related. Higher the protein content, greater was the recovery of head rice. On equal nitrogen basis, sulphur coated urea applied at planting was as effective as split application but significantly superior to ordinary urea when applied entirely at planting.
