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