The study aimed to improve sweet potato production in Nan'an by testing different fertilizers. They found that applying N,P,K fertilizer increased yield significantly. Soil nutrient levels were categorized into low, medium, and high ranges. The recommended fertilizer quantities for the highest yield were 197.43 kg/hm2 N, 63.84 kg/hm2 P2O5, and 226.32 kg/hm2 K2O. For the best economic outcome, the suggested amounts were 179.74 kg/hm2 N, 61.10 kg/hm2 P2O5, and 212.50 kg/hm2 K2O.
