Abstract
The research aims to study the applications of nitrogen fertilizer on pestsstem borers and leaffolders rice. The study was conducted in the subdistrict Syamtalira Aron district North Aceh from November 2013 until April 2014.The research using randomized block design (RBD) with the nitrogen dose treatment is without fertilizer, 45 kg N/ha, 67.5 kg N/ha, 90 kg N/ha, 112.5 kg N/ha, and 135 kg N/ha. Each treatment was repeated doses of nitrogen three times. Variables measured is the component intensity attacks of pests stem borers and leaffolders rice and components yield such as grain dry weight harvest, dry milled grain weight, and weight of 1000 seeds. The results showed that fertilization nitrogen of from dose 45 kg of N/ha to 135 kg N/ha can increase the intensity attacks of pest stem borers and leaffolders rice. The granting of nitrogen with 112.5 kg N/ha to 135 kg N/ha can reduce the weight of dry grain harvest, dry milled grain weight, and grain weight of 1000 seeds.
