A field trial was conducted to oversee the effects of controlled release urea (CRU) fertilizers on kenaf grown on the BRIS soil. Three types of formulated CRU were tested: (1) Meister-20, (2) CRU Duration Type V and (3) Uber-10 along with typical granular urea which acts as control set. Two rates of fertilizer at 300 and 600 kg N/ha were applied accordingly. Results demonstrated that the 300 kg N/ha fertilization was sufficient to ensure sufficient growth for sustainable kenaf production. The best CRU fertilizers, which were able to support the growth and nitrogen uptake of tested crop on the BRIS soil were: Meister-20> Duration Type V> Uber-10, respectively.
