Adaption of local rice cultivars Banten to drought environment

Abstract

Limited water availability or drought is an abiotic factor that inhibited rice production. One of the efforts to overcome this problem is by using plant varieties that can adapt to conditions of limited water availability. This study aims to determine the physiological and agronomic responses of some local rice cultivation in South Banten to drought conditions. The research was conducted from April to October 2017 in the greenhouse of the Faculty of Agriculture, Sultan Ageng Tirtayasa University, Banten. The experiment was based on factorial experiments in a completely randomized block design (RBD) with 3 replications. The first factor is the frequency of irrigation which consists of 2 levels, namely irrigation every 7 days and every 9 days. The second factor is the local rice cultivar in South Banten which consists of 8 levels, each of which consists of 7 local cultivars and one comparison variety, namely Rencong, Ketan Dewo, Kiara, Inpari 10 (as comparison varieties), Super, Kapundung, Cimoherang, and Ketan Elfi. The results of research show that cultivar of Ketan Dewo adaptive in drought environments.
