Resumo: 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 cultivated for many years, the results obtained show the viability of utilization and reclamation of such soils with gypsum and rice cultivars.

O delineamento experimental adotado foi o de blocos ao acaso com treze cultivares e três repetições. Foram incorporadas 40 t/ha de gesso comercial antes do lançamento do experimento, e como adubação foram utilizados 50, 30 e 10 kg/ha de N, P2O5 e K20, respectivamente. As cultivares testadas mostraram diferenças significativas ao nível de 0,01 de probabilidade em relação à produtividade, destacando-se a cultivar IR 2058-78-1-3-2-3, com produção média de 6,12 t/ha. Considerando-se a alta percentagem de sódio trocável, e que o solo não vinha sendo cultivado há vários anos, os resultados obtidos mostram viabilidade de utilização e recuperação desses solos com o emprego de gesso e cultivares de arroz que melhor se comportaram.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraGheyi, Hans RajBarreto, Aurelir NobreGarri, Arturo Carlos R.
