The experiment was conducted through two successive seasons of 2008 and 2009 at ElBosaily farm, EI-Behira governorate at the North Coastal of the Nile Delta, in Egypt. This work aimed to study the effect of three green-house covers (polyethylene sheet, white and black net) and three irrigation levels [80%, 100% and 120% of the potential evapotranspiration estimated according to class A pan equation (ET,)], applied by drip irrigation system, on plant growth and crop yield of Cucumber (Cucumis sativus L.. cv. Reda F1). The experimental design was split- plot with three replicates. The results showed that white net green-house cover optimized growth and yield of cucumber plant. White net cover treatment recorded the highest vegetative growth (plant height, number of leaves, total leaves area, total fresh and dry weights), and significantly increased total yield. The highest vegetative growth was obtained by 100% ET, compared to 80 and 120% ETo treatments. The interaction among water treatment and green-house cover indicated the highest vegetative growth and crop yield were obtained under white net cover wi1th 100% ET0,.

Two experiments were carried out under low polyethylene tunnels which furnished with drip irrigation during the two successive winter seasons of 2014-2015 and 2015-2016 at Elbrollous area which represents the circumstance and conditions of coastal zone of north Nile Delta kafr Elsheikh Governorate. The objective of the investigation was to find out the effect of grafting by different cucurbita rootstocks on cucumber hybrid "ESHRAK" (Cucumis sativus, L.) on vegetative growth, flowering, yield and fruit characteristics, beside nutrient contents of cucumber plants. Results showed that grafted cucumber plants on Super Shintoza led to significant increase in vegetative growth,i.e., stem length, number of leaves, number of branches and leaf area,fruit fresh weight (g), number of fruits, total yield were greater with grafted cucumber plants on Super Shintoza followed by grafted cucumber plants on cv. Ferro. However grafting had no significant effect on potassium % of fruit on both seasons. The highest total yield was obtained by grafting cucumber plants on Super Shintoza rootstock followed by grafting on cv. Ferro rootstock by 130 % and 73 %, respectively in the first season and 160% and 147 %, in the second season respectively as compared with ungrafted cucumber plants. Accordingly, this study ensured that the use of rootstocks were more beneficial than ungrafted cucumber in both tested seasons.
