Influence of Different Irrigation Levels on Varieties of Tomato (Lycopersicon esculentum Mill.)Under Plastic House Conditions.

Tomatoes are one of the more important horticultural crops in the world. The obtained results proved that the shortage irrigation has a negative effect on tomato development. More irrigation showed a decrease of morphological and production. The non-significant increase in irrigation of water will be increase of the efficiency and reduction. The study also, indicated that it is sensitive to tolerance for drought stress through greenhouse. At 80 % of water holding capacity led to save 36.30 % of the irrigation water and reduction in yield by 60.:9% in variety Kexin12. However, at 60% of water holding capacity resulted in 51.18 % of irrigation water saving but 89.66% of the in yield were lost. Supplying 40% will be save about 62.54 % of irrigation in produce by 9;.6 %. Therefore, the suggested results that supplying this variety Kexin 12 by 80% of WHC reduction in produce by 30.76% will be save 36.30 % of water.
