Abstract
It Is Of Interest To Find Best Way Of Increasing Productivity Of Maize By Water Management As Well As Exposing Grains To Gamma Rays To Eliminate The Effect Of Soil Moisture Stress. Therefore This Work Is Performed To Study The Mechanism Of Environmental Stress On The Morphology, Physiology, Yield And Yield Components Of Maize. Three Sets Of Experiments Are Performed To Realize This Target.U)Effect Of Skipping On Irrigation:Two Field Experiments Are Conducted During 1980 And 1981 At Ain Shams University Experimental Farm In Shoubra El-Kheima To Study The Effect Of Skipping One Irrigation On A Certain Stage Of Growth On Maize Plant.(2)Effect Of Water Deficit: Two Field Experiments Are Conducted In 1980,1981 In The Same Farm To Study The Effect Of Soil Moisture Deficit On Maize Plant(3) Effect Of Salinity And Gamma Radiation: Two Pot Experiments Are Performed In The Greenhousie Of Agriculture Department For Soils And Water Researches, Atomic Energy Establishment At Inshas In 1981 And 1982 Growth Seasons To Study The Effect Of Salinity And Gamma Rays On Maize Plant.
