Abstract

The most important nutrient for rice (Oryza sativa L.) production is nitrogen. But it lost from soil in different process. Proper nitrogen (N) management of high yielding rice varieties is crucial for obtaining their potential yield benefit. The area of the study is characterized by long rainy season which predispose for leaching of N to the ground water. A randomized block design with three replications was used to assess the response of upland rice Varity (Nerica 4) to N application intervals. N was investigated at six different levels or points in time. The N timing were: Applying all recommended N rate at planting, applying 50% of the N at planting and the other 50% at mid tillering, applying 50% of the N at planting and the other 50% at panicle initiation, applying 25% of the N at planting and 75% at mid tillering, applying 75% of the N at planting and 25% at panicle initiation, applying 25% of the N at planting, 25% at mid tillering and 25% at panicle initiation. The study shows that applying 50% of N at planting and the other 50% at tillering is best N management practice for the area to maximize rice yield avoiding the excess use of N fertilizer.
