Abstract:
Tomato (Lycopersicon esculantum.) is one of the major vegetable crops in A.R.E. During least few years the area devoted rapidly extended. While in 1960 it was 135833 Feddans, ten years later it increased up to 255656 faddans and further up to 331720 faddans in 1980, thus amounting to about one third of the total area planted with vegetable crops. The production in this vast area faces many problems the most important of which are irrigation and fertilization. In this situation, cycocl plays a great rol in the physiological process of plant among which is droughout resistant .The Present work aimes to determine the best irrigation practices and optimum leveis of nitrogen and potassium fertilization as well as best concentration of cycocyl for producing the highest economic yield. The effect of interaction between water supply and both fertilization and cycocyl was taken into consideration. the effect of all these factors on the growth, moisture status of leaves, chemical- composition, efficiency of water utilization, evapotranspi-ration, yield and quality of tomato plants was studiedAn population increases, the need for food production rises concomitantly. An indirect effect of salinity is its influence on soil microflora. Microorganisms activities such as ammonification and nitrification could be inhibited by salinization. Irrigation with saline water may indirectly, case an increase in the soil PH which could depress the availability of some miconutrients.
