This present research was carried out with objective to evaluated the rice dryland cultivars performance (Araguaia, Caiapó, Carajás and IAC 201), in two row spacing (0,20 e 0,40m) and five sowing population (50; 100; 150; 200 e 400 viables seeds/m2), sprinkler irrigated crops. The trials was conduced in Selvíria-MS (Brazil) in Dark Red Latossol (Oxisol, clay), in the period of 1995 until 1996. The experimental design utilized was randomized blocks, in split plot, with 40 treatments and four replications. The water manegemment were realized for tensiometers with irrigation always water potential reaching -0,033 in flowering and -0,058MPa in others development periods. It has been conclude that: the rice cultivars have differences in development, with vegetable cicle reduncing in five days for the cultivars Carajás and IAC 201 than the other two; the seed yiel were of 3.726; 3.832; 3.841 and 3900kg/ha for Araguaia, IAC 201, Caiapó and Carajás cultivars; the sowing density of 100 seeds/m2 was better than the other densities.
