  1. 1. The effect of water regimes on corn and wheat productionA.M AL-OMARAN – SOIL SCIENCE DEPT., COLLEGE OF AGRICULTURE, KING SAUD UNIVERSITY, EMIR, J. AGRIC. SCI. (1990) Meelika Raup EMÜ, TL
  2. 2. CONTENTS Introduction Methods and materials Results Conclusion
  3. 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. 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. 5. METHODS AND MATERIALS The soil of the field content Early planting time was chosen to avoid the high temperature
  6. 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. 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. 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. 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
  10. 10. REFERENCES Journal article „The effect of water regimes on corn and wheat production“ http://ejfa.info/article/view/5025
