Effect of Urea and KCl Fertilization on the Growth and Results of Gogo Rice of Situ Pateggang Variety

Rice requires nitrogen for the growth of plant vegetative organs. Potassium plays a role in regulating osmotic pressure and turgor plants, especially dry land. The purpose this study was to determine effect varieties potassium fertilization on yield upland rice. research conducted Bleberan Village, Kab. Gunungkidul continued at Laboratory Department Agricultural Cultivation, Faculty Agriculture, Gadjah Mada University. This used split-plot design three replications. Planting main plot is which consists no (0 kg.ha-1 Urea), according recommendation (350 Urea) twice recommended (700 Urea). Subplots kg.ha-1), (225 KCl), (450 KCL). planting uses polybags, per there are 10 polybags containing 3 rice seeds. There were 9 treatment combinations, each repeated times. Analysis data using variance, then Tukey test with level 5% carried out. results showed that Urea did not increase total weight plant, number panicles 1000 grain weight, clump. KCl dose 60 g/plot kg/ha) increased but yield.
