Results of a field research to study salinity and watering regime effects on artichoke ‘Violetto di Provenza’ are reported. The trial has been carried out during July-May in Policoro (Southern Italy) on a deep slimy-clay soil.
Three saline levels (water electrical conductivity-ECw equal to 0.5, 5 and 10 dS m-1, respectively showed as S0, S1 and S2) of irrigation water and three watering regimes (watering at 20, 40 and 60% of available water depletion, respectively showed as W1, W2 and W3), were compared.
In the whole, the salinity tolerance rating results are in agreement with those of literature for ‘Violetto di Provenza’, but it was demonstrated an higher tolerance when crop was watered more frequently (at 20% of available water depletion) and a lower one when crop watering was performed less frequently (at 60% of available water depletion). Water salinity reduced heads yield (from 12.1 to 9.1 n plant-1 and from 13.2 to 8.5 Mg ha-1) and heads mean weight (from 108.1 to 93.6 g), while increased heads dry matter. Watering regime, as average of the salinity levels, affected heads yield (11.3 n plant-1 and 11.4 Mg ha-1 for W1 and W2, 10.5 n plant-1 and 10.4 Mg ha-1 for W3) but not heads mean weight (100 g). However, water regime effect showed some differences connected to salinity levels. In condition of moderate salinity, maximum water depletion fraction was 40 and 20% of total soil available water to preserve heads number and yield weight, respectively. Instead, with high salinity, maximum water depletion fraction was 20% both for heads number and for yield weight.
