Abstract
Two field experiments were carried out during the summer seasons of 1999 and 2000 at Dina farm Km 80, Cairo, Alex. Road, Egypt to study the effects of different irrigation systems (surface, sprinkler and drip irrigation), three salinity levels (low 0.9-1.3; moderate 4.5-6.3 and high 9.0-12.4 dSm-1) on tomato yield, quality and chemical composition, under the conditions of two soil types (calcareous and sandy). A spilt spilt plot design was used.
 
The most important finding could be summarized as follow:
The highest fruit yield of tomato (c.v. Peto 86) was obtained from calcareous soil (EC. 1.3 dSm-1) under the drip irrigation system. The data also revealed that the lowest fruit yield was produced from the saline sodic calcareous soil (12.4 dSm-1 and 62.8 meq/L soluble Na+) also under the drip irrigation system. The data showed that there was an increase in total soluble salts and total acidity in tomato ripe fruit with drip irrigation during the two seasons. Fruit quality characters were also affected by soil types and salinity levels. The concentrations of N, P and K (%) in tomato plants decreased significantly with increasing salinity. Higher contents of nutrients were produced in tomato tissues under the calcareous soil conditions.
The results of this investigation recommended the drip irrigation system as the best method under the low and moderate salinity levels, while better results could be achieved with surface irrigation under the higher levels of soil salinity than those of sprinkler irrigation.
