Abstract

The application of neem extract coated urea (NCU) 50% basL .. 2.')% at tlllering +
25% at panicle initiation (PI) stage recorded the maximwn grain and straw yield. N concentration
and uptake, nitrogen use efficiency and nitrogen r,!covery. The application of 30% NEU
as basal + priDed urea (PU) 40% at tlUering and 30% at PI stage or NCU 75% basal and 25%
at PI stage performed as good as application of NCU 50% basal + 25 at tillering + 25% at PI
stage for grain yield, N concentration and N uptake of rice.
