Yield, fruit quality and leaf mineral content of mango trees as affected by subsurface drip irrigation system

FagriKalan mango trees which grown under sandy soil conditions were irrigated with 12, 9 or 6 drippers per tree, either as a subsurface or surface irrigation system. The effect of the irrigation system and the number of drippers on yield, fruit quality, chlorophyll and leaf mineral content were studied. The obtained results indicate that the subsurface irrigation system was more effective than the surface one. In addition, the drippers' number shows different effects concerning yield per tree or the fruit's quality and the leaf mineral content. From one hand, it could be concluded that the trees which were irrigated with 9 subsurface drippers save the irrigation water without significant decrease in the yield compared to the control. On the other hand, as a subsurface dripper irrigation system, the highest significant yield as Kg/ tree was obtained due to 12 drippers/ tree compared with the 9 or 6 drippers/ tree.
