Abstract
3 Abstract: This investigation was carried out in lysimeters at the Experimental Station of Arid Land Cultivation Research Istitute, Ain Shams University, Cairo, in the early summer seasons of 2008 and 2009. This work aimed to study the response of sweet pepper CV, Mader grown in two soil types (sandy and clay) to four water regiemes (50, 70, 90 and 110 % of ET , culculated by Penman equation). The results revealed that moderate 0 (90 % ET ) and medium (70 % ET ) irrigation regimes were able to compete high irrigation levels (110 % of ET ) 00 0 regarding sweet pepper vegetative growth traits ie., plant length, stem diameter, total fresh and dry weight of plants and root/ shoot ratio as well as early yield. Since there were no recorded significant differences among them, even there were high or very high significance for investigated irrigation regimes on most recorded vegetative growth traits. Concerning early yield also, there were significant effects of investigated irrigation regimes at 5% levels. Regarding total yield, average fruit weight and water use effeceincy, high irrigation levels exhibited significantly higher values than those obtained from moderate irrigation levels which exceeded medium irrigation levels without significant differences between moderate and medium irrigation levels. Opposite trend was detected in sweet pepper fruits total soluble solids. Plants grown in clay soil were significantly superior to those grown in sandy soil, regarding the vegetative growth traits, yield components and most of recorded fruits characters. There were no significant effects of soil types on water use effeceincy. Plants grown in clay soil and irrigated with high or moderate levels of ET (110 or 90 %) produced the highest 0 values of most investigated characters under the present condition. Meanwhile, under lemited irrigation water supply medium (70% of ET ) irrigation regime might be applied since, only minor reduction in yield occurred 0 parallel with great water consumption could be reduced.
