Abstract
ABSTRACT : A field experiment was carried out according to a randomized complete block design ( RCBD ) in greenhouses of the Ministry of Agriculture - State Company for gardening and forestry for the agricultural season 2007 - 2008 to consider the impact of irrigation scheduled with the levels of mineral fertilization and interfering on the growth of tomato growth and yield Cambion variety. Three combinations of mineral fertilizers (NPK) kg / ha, is (350-100-400) (F1) and (550-150-600) (F2) and (750-200-800) (F3).Were added and four levels of irrigation (irrigation per day) (comparison) and (irrigation between the day and last) (C1) and (left two days after irrigation) (C2) and (irrigation after leaving three days)(C3). The results showed that concentrations of nitrogen , phosphorus and potassium were increased when the interfering with the rationalization of irrigation water as well and it increased when increasing levels of added fertilizer significant and reached its highest value at the level of addendum (550-150-600) kg / ha and also resulted in conserving Add water and fertilizer and metal interfering to increase the percentage of dry matter and the total yield were encouraged to continue conserving water with the addition of mineral fertilizer to increase water efficiency.
