A study was done to find the best way to grow super rice with high yields. By using a mix of slow-release and organic fertilizers, the roots of the rice plants grew better and absorbed more nutrients. This helped the rice plants stay healthy for longer, leading to higher yields. On average, double-cropped rice produced 646.2 kg per 667 square meters, with a maximum of 712.4 kg. By using slow-release fertilizer, farmers can save money and increase efficiency while growing super rice.
