A field experiment in a saline-sodic soil of the irrigated perimeter of São Gonçalo-Sousa, PB, Brazil, was carried out with the objective to select cultivars of irrigated rice (Oryza sativa L.) for salt affected soils. A random block design with thirteen cultivars and three replications was adopted. Before the start of the experiment, 40 t/ha of gypsum were incorporated in the soil, and N, P2O5 and K2O were applied at the rate of 5O, 30 and 10 kg/ha, respectively. The cultivars under study showed significant yield differences at 0.01 probability level and a mean production of 6.12 t/ha was obtained for the cultivar IR 2058-78-1-3-2-3. Considering the high exchangeable sodium percentage and the fact that experimental plot has not been cultiv...
