How to irrigate a pistachio tree

In general, the water required for pistachio shell pistachio seedlings in the flood method will be about 4,000 cubic meters per hectare per year for 4 to 5 year old seedlings, and the same amount is recommended for irrigating one year old seedlings, because pistachio plants per year First, it has just been moved to its original location and has little rooting development, so its actual need is much less than 4,000 cubic meters, and even less than 1,000 cubic meters per hectare in the first year, which is only possible with modern systems or the same method. The pressurized system can be given to the plant and this is not possible with the flood method.

When we pay attention to the amount of water required for pistachio trees for different irrigation methods in terms of cubic meters per hectare per year for different climatic conditions, which are as follows, we realize the importance of modern irrigation systems:
Surface and flood irrigation: 9,000 cubic meters per hectare per year
Irrigation of Babol: 7,000 cubic meters per hectare per year
Drip irrigation: 5,000 cubic meters per hectare per year
