Summary : Riam Kanan is an irrigation, which built from Riam Kanan dam, have potential farm 25,900 ha, done in 5 stage cover 5 sub areas (A,B,C,D and E)). In dry season, farmers need irrigation water for their rice plant system, but wrong design and construction caused water supply interrupted. In another side, during rain season, farmer doesn't need irrigation water. Martapura river and rain flood their farm, and soil be come more acid. In this irrigation area, including floated farm have 2-plant season in on year, local rice and hybrid rice. rice citification started by fermentation in molded farm called "Meneradak" (Banjar language), first movement to "Ampak", second movement to "Lacak", than cultivate in water farm. In farm level, soil treatment and citification still traditional, rare tractor found. After rice plant in watered farm, usually farmer doesn't do citification activity unless pest and disease control. Farmers use Urea, TSP, KCL, and salt for fertilize. Local rice plant in rain season, with life cycle 8 month with production mean 2-3 ton/ha. In second plant system, farmer plant hybrid rice, but still less than 60% caused rat pest, and the productivity less than local rice. In non-irrigation farm, citification only can do in first plant season. In second plant season, they can't cultivate cause their farm are floated, basically this area nedd dryness. Some farmer uses it to aqua culture activity in order to rise their income.
