<![CDATA[Rice is one of the important plants being a staple food for almost the whole Indonesians. Upland (Gogo) rice can be increased by extensification using coastal sandy land. The upland cultivation techniques on the sandy land need an appropriate method to obtain high growth and production. This study aims to examine the effect of tillage on sandy land toward the three upland rice (Oryza sativa L.) varieties to rice growth and production. This study was conducted using a 3 x 3 split-plot experiment with a Randomized Block Design (RBD) consisting of 4 groups. The tillage methods as the main plot are J1: without tillage, J2: partially tillage, J3: fully tillage. The rice varieties as the subplots are P1: inpago, P2: inpago 10, P3: inpago 12. The observation parameters are plant height, number of tillers, the age of panicles appear, number of panicles, plant wet weight, plant dry weight, net assimilation rate, number of grains per panicle, grains production, the weight of 1000 seeds, harvest index, and the percentage of the filled grains. The result of the study shows that the tillage method has a real and significant effect (P<0, 05) on Upland rice growth and production. The inpago 8 variety without tillage was able to produce the highest dry weight and 1000 seeds. The highest grain production was in the partially tillage method. The inpago 10 variety in the partial tillage method was able to produce the highest number of grains per panicle, grains production, 1000 seeds weight and harvest index. However, in the partial tillage method, inpago 12 variety was able to produce the highest grains per panicle, grains production, 1000 seeds weight and harvest index while without tillage method produced the highest dry weight and the highest filled grains percentage.]]>
