Abstract
In order to study the effect of gypsum on the chemical attributes of a saline-sodic soil and growth of guava and custard apple. The study was conducted in a greenhouse UFCG / CSTR in Patos, PB. Samples of a saline-sodic soil were obtained from the Irrigation São Gonçalo. The experiment consisted of one soil, two species, three doses of gypsum (00, 100 and 200% NG) and 4 replicates. The plots were distributed in a completely randomized. The pineapple and guava seeds were sown in plastic tubes and 30 days after sowing, the seedlings were transplanted according to the standardization of stem diameter, number of leaves, height and transferred to saline soils, noting growth through weekly measurements of height Plants for a period of 104 days. Significant reduction in the levels of sodium in the soil with increasing level of plaster applied, the same is true for pH and improvement in the soil properties. The seedlings had reduced height, number of leaves, dry weight of shoot and root with the application of concealer. The application of gypsum in saline-sodic soils for cultivation of guava and custard apple did not provide satisfactory results.
