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
METHODS AND MATERIALS

   Experiments were taken over four years from
    1985 to 1988

   Each experiment consisted of three different
    regimes - wet, medium and dry
METHODS AND MATERIALS

   The soil of the field content

   Early planting time was chosen to avoid the high
    temperature
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
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.
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.
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
