Abstract

This research was conducted to compare the reducing of irrigation water from some cultivation, cultivation model were System of Rice Intensification method (SRI), ngenyatin technique and the conventional cultivation, as well as compared the productivity of rice plants cultivation. This research consists of four treatments with three repetitions, which is conventional treatment, SRI method, Ngenyatin technique, and the combination of SRI method and Ngenyatin technique. Parameters that observed in this research were: the needs of irrigation water, the reducing of irrigation water each treatments compared to K0, the weight of clumps, the seeds weight per clump, the stalks length, the seeds amount per stalk, the amount of productive seeds, the rice weight per clump, the percentage of rice based on its amount, the percentage of rice based on its weight, the weight of 100 grains and the result rice plants production. The research results show significant differences with cultivation technique between the treatments that influence to the thrift of irrigation water in every treatments and influence to the rice plants productivity. K3 treatment that applied the SRI method that combined with Ngenyatin system which is the best treatment by minimize the using of irrigation water up to 58% compared than K0 treatment that applied conventional planting and produced 8.85ton/ha productivity compared with other treatments.
