Abstract

Upland rice production can be increased by utilizing suboptimal land. However, efforts need to be made to increase the availability ofnutrients and water in the soil. This study aims to determine the interaction of rice husk zeolite treatment andN fertilizer on the growth and yield of upland rice. The research was conducted experimentally factorial using completely randomized design (CRD). The first factor of rice husk zeolite consisted of 3 levels (0, 200 and 400 kg.ha^-1) and the second factor of N fertilizer consisted of 3 levels (0, 75 and 125 kg N.ha^-1), each combination was repeated three times. The results showed that the application of rice husk zeolite 200 kg.ha^-1 and N fertilizer dosage 125 kg N.ha^-1 increased plant height, maximum number of tillers and weight of 1000 grains compared without rice husk zeolite and N fertilizer, and also increased the number of productive tillers and pithy grain per panicle, weight of dry milled grain per clump are 56.78%,16.8%, 80%, respectively compared without rice husk zeolite and N fertilizer.
