Abstract

A research trail was executed during kharif -2018 to know the effect of different nitrogen enriched sources on nitrogen use efficiency in transplanted rice. The results showed that highest Agronomic Efficiency (AEN) (29.8), Physiological Efficiency (PEN) (103.8), Apparent Recovery Efficiency (AREN) (59%) and Agro Physiological Efficiency (APEN) (50.30) was recorded with application of 100% RDN through neem coated urea (T7). Highest Partial Nutrient Balance (PNBN) (1.08) and Partial Factor Productivity (PFPN) (60.99) were achieved with application of 75% RDN through neem coated urea.
