Effect of Arginine on Growth Characters of Two Maize Hybrids under Water Deficit conditions

Type: article
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 growth characters of two maize hybrids (Fine Seeds-101 and T.W. 329).Normal irrigation gave the highest value in all growth characters under study followed by omitting the 5 th irrigation + 200cm 3 / fed., arginine.Fine Seeds-101 cultivar significantly surpassed T.W. 329 cultivar in plant height (cm), total dry weight / plant (g), number of ear /plant, leaf area (dm 2 ), leaf area index, leaf area ratio, specific leaf area and specific leaf weight in both seasons.The interaction between maize cultivars and water shortage with or without arginine were significant in all growth characters in both seasons except leaf area (dm 2 ) and leaf area index.The best treatment for plant height (cm), total dry weight / plant (g), number of ear /plant, leaf area ratio, specific leaf area and specific leaf weight was normal irrigation + Fine seeds-101.Also, the best treatment was omitting 5 th irrigation + 200 cm 3 / fed., arginine with Fine Seeds-101 cultivar for plant height (cm), total dry weight / plant (g) and leaf area ratio.
