Abstract

Tomato (Lycopersicon esculentum Mill.) is one of the most consumed vegetables in the world. In Paraiba State, the yield is bellow the national average, and the salinity has contributed for this. This work aimed to evaluate the salinity effects in growth, plant nutrition and yield on two tomato cultivars. Santa Adelia and Meia Estaca cultivars were irrigated with saline water (0.4; 1.5; 3.0; 3.5; and 6.0 dS m-1), in a 2x5 factorial design, with 3 replications. Shoots and roots dry matter, the relative growth rate, N, K, Ca, Mg, S, and Na contents in the leaves, and fruits yield were analyzed. The salinity reduced shoot dry matter in Santa Adelia cultivar. Both cultivars had different behaviors related to leaf ion contents. The salinity reduced the fruit yield. Meia Estaca cultivar was more salt tolerant than Santa Adelia cultivar.
