Abstract
Rice is a strategic commodity for Indonesia. NPK fertilizer is a compound fertilizer with fast absorption, accelerates flowering, fruiting, flowering process and stimulates shoot growth. The pest that often attacks rice is Leptocorisa acuta which sucks the grain in the ripening phase and sucks the grain until it is empty or filling is not full, resulting in a decrease in production. This study used a non-factorial Randomized Block Design with 8 replications and 3 treatments of NPK fertilizer doses which included NPK P1 fertilizer: 100 kg/ha; P2: 200 kg/ha NPK fertilizer and P3: 300 kg/ha NPK fertilizer. The results showed that the application of several doses of NPK fertilizer had no significant effect on the intensity of L. acuta attack due to an increase in population. The highest population of L. acuta was found in the application of 100 kg/ha NPK fertilizer with an average of 17.50 individuals. The increase in new individuals is influenced by the availability of feed and pest control is not carried out. The application of several doses of NPK fertilizer did not significantly affect rice production, due to the high intensity of L. acuta attack which caused a decrease in rice production.
