Abstract
The effects of saline irrigation and organic waste fertilization on mineral composition of leaves and fruits of tomato plants grown in a calcareous soil were studied during two culture seasons (spring-summer, autumn-winter). Sewage sludge and almond by-product were added along with three levels of salinity provided by NaCl. The results showed that sewage sludge affected N and P content. The major effect of saline irrigation was to increase Na concentration. In general, greater concentrations in leaves of N, P, K, Ca, Mg, Fe, Mn, Cu and Zn were found in the second season. Yield was greater in the first season. Treatments containing sewage sludge produced more number of fruits.
