Abstract: Center, Aswan governorate during two successive late summer seasons of 2009 and 2010. the aim of this study is to investigate the effect of four shading levels (without shading, 40%, 63% and 73%) installed on solid iron framed low tunnels and draped over the bed after 4 weeks from seeds sowing, and four irrigation levels (70%, 85%, 100% and115% of the potential evapotranspiration "ETo") applied by drip irrigation system on growth and productivity of Cantaloupe (Cucmis melon L. var cantaloupenses cv. Royal F1 hybrid). Different measurements have been collected during the experimental time such as: Air temperature (°C), Relative humidity %, Plant height (cm), Leaf area (cm2), Total chlorophyll (SPAD), Number of leaves, Early yield per plant (g/plant), Total yield per plant (kg/plant), Total soluble solids (T.S.S) and Water Use Efficiency (kg/m3). The experiment was arranged in split-plot design with three replicates, the irrigation levels arranged in the main plots where shading levels where arranged in sub main plots. The collected data showed that irrigation level 85% gave the highest yield (4.84 kg/plant), also the shading level 63% obtained the highest yield (5.42 kg/plant), on the other hand, shading level 63% under 85% irrigation level gave the best yield (5.69 kg/plant). Moreover, shading level 63% increased water use efficiency (WUE) under irrigation level 70% of ETo (37.7 kg/m3). It can be concluded that the shading could enhance the water saving and increase the growth and yield by optimizing the climate conditions around the plants under the arid land conditions of Toshka region.
