Characterization of Nitrogen Uptake Pattern in Malaysian Rice MR219 at Differ…

Nitrogen (N) use efficiency is usually less than 50%, and it remains a major problem in rice cultivation. Controlled release fertilizer (CRF) technology is one of the well-known efforts to overcome this problem. The efficiency of CRF, however, is very much dependent on the timing of nutrient release. This study was conducted to determine the precise time of N uptake by rice as a guideline to…
