Akta Agrosia Organic Fertilizer Application for the Cultivation of Sidenuk Rice Variety to Reduce Urea Usage

(Sidenuk rice is a superior variety produced through a radiation mutation technique. The new varieties need to be supported by optimizing the rice production through fertilization technology. The purpose of this study was to determine if the organic fertilizer can increase growth, production and reduce the use of urea fertilizer in lowland rice. The study was conducted in a completely randomized design. Each treatment was repeated 4 times so that the total experimental unit was 32 rice pots. The treatments include (1) Control (without urea fertilizer), (2) Control (+) 100% urea, (3) 50% urea, (4) Local microorganisms (LOM), (5) Compost, (6) Biochar , (7) Azolla, (8) LOM + Compost + Biochar + Azola + SP 36 and KCl. The results showed that the highest grain weight was found on the treatment of 100% urea which was 43.97 g plant. MKBA treatment (LOM fertilizer, compost, biochar, azolla) were not significantly different from 100% urea treatment. The result indicated that organic fertilizer formula (LOM fertilizer, compost, biochar, azolla) can reduce the use of urea fertilizer by 50%. Akta Agrosia
