EFFECTS OF DIFFERENT LEACHING FRACTIONS ON TOMATO PRODUCTION
This study was conducted during the autumn and spring seasons of 2003 and 2004 to determine the effects of three leaching fractions on yield, fruit quality, water and nutrient saving of tomato plants grown in substrate culture. Irrigation was realized according to the leaching fractions adjusted as 10%, 20%, 30% or 40% in both growing seasons. The results showed that total yield and water consumption decreased with the decrease of leaching fraction. The highest yield was obtained from the highest leaching fraction in both seasons (8.95 kg.m-2 in autumn and 14.46 kg.m-2 in spring). The amount of applied nutrient solutions was reduced by 23, 39 and 50% at LF levels of 30, 20 and 10%, respectively, compared to 40% in autumn. In spring growing season, the savings were 22, 37 and 43%.
