Black rice is a type of rice that has a high nutritional content and beneficial in <br /> <br /> health, but this rice has not been cultivated because it has a low productivity. an <br /> <br /> effort that can be done is to provide growth stimuli such as GA3 to promote growth <br /> <br /> and development that is applied using the SRI method. The purpose of this study is <br /> <br /> to determine the effect of different concentrations of GA3 on growth and yield of <br /> <br /> black rice var. Cempo Ireng and get the best concentration of GA3 for growth and <br /> <br /> yield of black rice var. Cempo Ireng on SRI method. The experimental design used <br /> <br /> in this study was Randomized Block Design, consisting of 4 treatment of GA3 <br /> <br /> concentration, 0 ppm, 10 ppm, 20 ppm, and 30 ppm, and with 7 repetitions. The <br /> <br /> results showed that the difference of concentration of GA3 gave significant <br /> <br /> difference to growth parameter of leaf number, number of tiller, plant height, and <br /> <br /> number of panicles but not significantly different in growth parameter of flowering <br /> <br /> age and dry weight weighting parameter, weight of 1000 grains, panicles, harvest <br /> <br /> index, and productivity. The concentration of 0 ppm gives the highest number of <br /> <br /> leaves and number of tillers ie 235 leaves and 57 tillers. The concentration of GA3 <br /> <br /> 20 ppm gives the highest plant height that is 84,29 cm. While the highest number of <br /> <br /> panicles are at concentrations of GA3 0 and 10 ppm, ie 31 panicles. The <br /> <br /> concentration of GA3 gives the best effect on the growth of black rice var. Cempo <br /> <br /> Ireng is 0 ppm with flowering period of 98 HST, while the concentration of GA3 <br /> <br /> which gives the best effect to the result of black var crop. Cempo Ireng is 10 ppm <br /> <br /> and 30 ppm. GA3 10 ppm produces the highest dry weight and productivity of <br /> <br /> 124,77 grams and 4,27 ton / ha, and GA3 30 ppm yields 1000 seeds and the highest <br /> <br /> grain of per panicle of 22,01 gram and 142,57 gram.
