ABSTRACT
This study aims to determine the effect of organic and inorganic fertilizers in suppressing the attack percentage of the white rice stem borer (Scirpophaga innotata Wlk.) and to determine the type of fertilizer that can increase rice production. The method in this study was using a randomized block design (RBD) with the following treatments: P0: control; P1: Organic Fertilizer (cow stable); P2: Compost Organic Fertilizer; P3: Single NPK Fertilizer (Urea, SP36 and KCl) P4: Compound NPK Fertilizer (16:16:16). The implementation of the research begins with the manufacture of organic fertilizer, then planting, application of treatments, data collection, and analysis of observational data so that the effect of applying fertilizer on the percentage of pest attacks and rice production will be obtained. The results showed that the application of organic and inorganic fertilizers increased the number of tillers, the number of panicles, the weight of 1000 grains, and the production per plot and was able to reduce the percentage of pest attacks. The application of 100 kg of manure per plot was the best treatment in increasing the number of tillers, the number of panicles, the weight of 1000 grains and the production per plot and the best in reducing the percentage of attack by the rice stem borer.
