Abstract:
Studies were conducted on the effects of application methods on the recovery of fertilizer N by rice plant (Oryza sativa L.) using 15N labeled urea in microplots at the International Rice Research Institute (IRRI) in 1981.Uniform placement with prilled urea and point placement with urea supergranule (SGU) gave the highest yields(6.4t/ha) with the efficiency of 51Kg rough rice/Kg N in dry season.IN wet season,Point placement with SGU produced the highest yield (4.4t/ha) with the efficiency of 40 Kg rough rice/kg N.
