The researchers analyzed the effects of different fertilizers on paddy rice production in a specific area. They used regression analysis to create a model that predicts rice output based on nitrogen, phosphorus, and potassium fertilizer levels. The optimal fertilizer amounts for maximum yield were found to be 167.17 kg.hm-2 of nitrogen, 111.45 kg.hm-2 of phosphate, and 129.21 kg.hm-2 of potassic fertilizers. For the best economic outcome, the researchers recommend applying 160.27 kg.hm-2 of nitrogen, 111.28 kg.hm-2 of phosphate, and 113.47 kg.hm-2 of potassic fertilizers, resulting in a rice output of 11265.85 kg.hm-2.
