Two experiments were conducted during the summer and winter seasons of 2013 to study the effect of grafting using different rootstocks on the yield and quality and chemical analysis of cucumber (Cucumis sativus L.) cultivar "Hady" under high and low temperatures. The experiments consisted of 5 treatments, 4 rootstocks, namely Bottle Gourd (Lagenaria siceraria Standl.), Supper Shintosa (Cucurbita maxima Duchesne{u00D7}Cucurbita moschata Duchesne), Squash 3 (Cucurbita pepo) and Ferro{u2019} (C. maxima {u00D7} C. moschata), in addition to non-grafted control. Data were recorded on plant length and physical characters of fruits 30, 60 and 90 days after planting, early and total yield/m2, chemical characters (percentage of dry matter, TSS, total and reducing sugars) of cucumber fruits and percentage of N, P and K in cucumber leaves. The results indicated that Frro rootstock increased plant height, physical characters, early and total yield of cucumber fruits in both summer and winter seasons, as compared with non-grafted control
