3. INTRODUCTION
 Effects of water regime on corn and wheat
production in the Kingdom of Saudi Arabia
 Most limiting factor in Saudi Arabia is water
deficit

4. METHODS AND MATERIALS
 Experiments were taken over four years from
1985 to 1988
 Each experiment consisted of three different
regimes - wet, medium and dry

5. METHODS AND MATERIALS
 The soil of the field content
 Early planting time was chosen to avoid the high
temperature

6. METHODS AND MATERIALS
 Wet regime, 1190 mm of water were added in 17
irrigations in the first season and 840 mm in 12
irrigations in the second season
 Medium regime, 840 and 560 mm of water were
given for first and second seasons
 Dry regime, 770 and 420 mm of water

7. RESULTS OF CORN
 The results of corn experiment showed that the
yield of corn was not significantly affected by the
water regime treatments
 Causes might be:
 theamount of water applied
 water quality.

8. RESULTS OF WHEAT
 The results of wheat showed that:
 the wet regime gave significantly taller plants and
heavier seeds
 significantly greater seed and biological yields than
meedium and dry regimes.

9. CONCLUSION
 It can be concluded that the corn may not tolerate
irrigation deficit and saline water quality
 Wheat recorded a high yield of some water stress
