Conteúdo: 	The investigation was conducted to study the efficiency and effects of 4 periodical leaching treatments (T1= leaching at each irrigation; T2= leaching after one month of irrigation with saline water; T3= leaching after two months of irrigation with saline water; T4= leaching after harvest) in combination with 4 salinity levels of irrigation water (0.9, 3.0, 6.0 and 9.0 dS/m) on durum wheat growth and yield parameters response; drainage water behaviour (salt output calculated from C1- concentrations and volumes of the drainage water volumes); and on the final salt distribution in the soil profile after the irrigation period. It was found that growth parameters, such as the height of plant, the number of spikes and the number of spiklets per spike, were neither influenced by the 4 different water salinities nor by the 4 leaching treatments. However, grain yield and straw weight were much more influenced by water salinity level in irrigation water.   ...
