Adaptation of new superior varieties of rice to seawater intruded land in Mootilango Village, Duhiadaa District, Pohuwato Regency, Gorontalo Province

Abstract

Seawater intrusion of paddy fields is one of the limiting factors in increasing the productivity of rice fields in Duhiadaa District. This study aims to see the adaptability of several new superior varieties of rice in seawater intrusive paddy fields in Mootilango village, Duhiadaa district. The method used in this study was a randomized block design with several treatments, namely V1 = Banyuasin variety, V2 = Inpari 34, V3 = Mekonga, V4 = Inpari 30 which was repeated three times and analyzed using the SAS program (one way ANOVA), if showed significantly different results then continued with Duncan's continued test at the 5% real level. The data show that the treatment of Banyuasin and Inpari 30 varieties is able to adapt well to seawater intrusive land. This was indicated by the higher number of productive tillers and the number of filled grains, as well as the high weight of a thousand grains compared to the treatment of Inpari 34 and Mekonga varieties.
