Irrigation management is one of the most important factors for water saving, especially with limited water resources in Egypt. so, the present study was carried out during 2017 and 2018 on trees of Lime (Citrus aurantifolia), grown in sandy soil at Asyut Agriculture Research Station ARC, Asyut Governorate, Egypt, to elucidate the effect of different irrigation regimes; 100%, 80% and 60% of ETc and spraying (SA); with and without spraying on yield, fruit quality and marketability; room temperature and cold temperature. The results can be summarized as follows: irrigation with 100% ETc and spraying SA recorded the highest values of Fruit length, fruit width, Fruit weight and Yield compared with the other irrigation regimes. While, irrigation with 60% ETc and spraying SA recorded the highest values of irrigation water productivity and economic water productivity in both seasons. Also, irrigation fruits with 100% ETc and treated with SA during growth season induced the highest level of Juice weight %. Moreover, the obtained results indicated that irrigation fruits with 60% ETc and treated with SA decreased weight loss % and decay % while, increased TSS %, total acidity in fruit juice, and V.C content of mature fruit compared with the other treatments under marketability.
