Abstract: Two field experiments were carried out at private farm Wadi El-Rayyan, El-Fayoum governorate, Egypt, during the two successive summer seasons of 2017 and 2018 to study the effect of skipping one irrigation with or without arginine on yield and yield components of two maize hybrids (Fine Seeds-101 and T.W. 329).Omitting 5 th irrigation + 200 cm 3 / fed., arginine gave the highest values followed by control in plant height, ear length (cm), ear diameter (cm), number of row / ear, grain index, grain yield / plant, grain yield / fed., straw yield / fed., and biological yield / fed., while control gave the highest values for straw yield / plant , harvest index, protein and carbohydrate percentage.Fine Seeds-101 cultivar significantly surpassed T.W. 329 cultivar in plant height (cm), ear length (cm), ear diameter (cm), number of row / ear, grain index, grain yield / plant, straw yield / plant, protein and carbohydrate percentage in both seasons, while the differences between the two maize cultivars in grain, straw, biological yields per feddan and harvest index were not significant in both seasons.The interaction between maize cultivars and water shortage with or without arginine were not significant in all characters under study except plant height (cm), number of row / ear, grain index, grain yield / plant, biological yield / fed., and carbohydrate percentage in both seasons, where the best treatment was omitting 5 th irrigation + 200 cm 3 / fed., arginine with Fine Seeds-101 cultivar.
