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
