Abstract
Agriculture is inherently sensitive to weat her and climate. Adaptation of an appropriate management strategy is one of the likely decisions to cope with the impacts of changing climate. This study was designed to explore the role of arginine (0.0, 2.5 and 5.0 mM) in increasing the tolerance of wheat cultivar (Sakha-93) to two late sowing (23/12 and 23/1) dates, beside the normal sowing date (23/11) in Egypt. A field experiment was conducted in Agricultural Research Station of National Research Centre located in Shalkan Province, Kaluobia Governorate, Egypt. Delayed sowing caused marked reduction in biological and economic yield, through reduction in the spike length and weight, spike grain weight, spike no per square meter, and 1000-grains weight. The reduction in economic yield/fed reached to 10.39 and 41.22% when delay sowing wheat to 23/12 and 23/1 respectively. Foliar application of arginine with 2.5 and 5.0 mM on normal or delayed sowing wheat exhibited significant increment in yield and its components in comparison to untreated plants. The magnitude of increments was much more pronounced in response to 2.5 mM of arginine which induce 19.23, 20.53 and 25.51% increases in economic yield per feddan at normally, 30 and 60 days delay, respectively. As we ll as results show that, 2.5 mM arginine treatment induce 8.0% increase in grain yield over the plants sowing late at 23/12 and could reduce the reduction percent in grain yield from 41.22 to 26.22% at 23/1 sowing date. From this study it could be concluded that arginine could alleviate the adverse impact of climate change by late sowing of wheat and reduce the expected reduction of economic yield in semi-arid regions under irrigated agriculture.
