| Abstract | ||||
| Field experiments were carried out in the environmental conditions of Dakahleya governorate. The effect of irrigation levels (100%, 85% and 70% of ETcrop), fertilization methods (traditional and fertigation) and drip irrigation systems (surface and subsurface) on tomato were investigated in this study. The main aims of this study are: - Study the effect of irrigation system and amount of irrigation water on total yield. - Effect of using fertigation system. - Effect of studying factor on emitter clogging. The results show that: - Irrigation level has strong effect on yield. - The highest yield (5411 kg/fed) obtained with treatment L1F2D2 (irrigation with 100% ETcrop with fertigation method under using subsurface drip irrigation system). - Maximum water use efficiency (4.96 kg/m3) obtained with treatment L3F2D2 (irrigation with 70% ETcrop with fertigation method under using subsurface drip irrigation system). | ||||
