A Study of the Effect of Replacing Drip Irrigation System by Micro-Sprinklers in Avocado (Persea americana Mill) in Morocco
In this work, we implemented a new irrigation system based on micro-sprinklers specially adapted for sandy soils instead of the drip system usually used in the avocado irrigation. This process has resulted in a very pronounced improvement of the tree's condition in general and that of the leaves and fruits in particular. This can be related to the increase of the irrigated surface as well as the wetted volume, without disregarding the stimulation of the physiological and metabolic activity of the tree as a result of the increase of the quantity of usable water absorbed and improving water productivity as well as the surface exploited by the radical system of the tree. This technique usually unusable for fruit trees in Morocco, allowed us to reduce the expenses of the farm in which we carried out our tests, in terms of water consumption by 16% and electricity by a quantity proportional to that of the water used. We have also managed to significantly increase the yield by 35% without altering or disturbing the natural balance of the environment and by rationalizing water consumption, we have also reduced the amount of pollutant-rich water that can eventually seep into the ground and thus contaminate the water table.
