Saline water on chemical properties of soil and nutritional status of Cassava

The purpose of this study was to assess the influence of saline water on chemical properties of the soil and nutritional attributes of cassava. The work was conducted in the area of Irrigation and Drainage of IF Baiano, Campus de Senhor do Bonfim, BA (10° 28’S, 40° 11’W and 550 m). The experimental design was completely randomized, consisting of seven treatments and three replicates. The treatments consisted of control (rainfed), a treatment irrigated with drinking water (100% of ETc) and five treatments irrigated with saline water of 3 dS m-1 with varying water depths: 110, 120, 130, 140 and 150% of ETc. The use of saline water increased the exchangeable sodium percentage, the sodium adsortion ratio and the electrical conductivity of the soil in both 0-0.20 and 0.20-0.40 m dephts. Regarding the leaf nutritional status of cassava, the treatments influenced only the contents of calcium, magnesium and chlorine.
