Foliar application for fruit set 5 per thousand urea, 5 Iranian Pistachio per thousand zinc sulfate and 5 per

Thousands of acids were introduced to the operation and had 77 boric acid pistachios. In autumn

After pistachio harvest or early spring at the time of bud swelling

It can be seen in both times, even if the soil is salty

Boron is removed from the formula. Zinc is one of the key and effective elements in practice

Pollination and inoculation are present in all trees.

Zinc is involved in the germination of pollen grains and helps pollen tube growth

And causes fertilization and fruit formation. Zinc deficiency delays opening

Reproductive and vegetative buds grow on the tree. Also the number of seeds per spike

They are also reduced, causing the clusters in the trees to become thinner. Puki is also another

Complications of deficiency of this element. The element also plays a role in pollination and fertilization

It is important. Prove the major role of this element in flowering and in pollen potency and inoculation

Has been. Deficiency of this element causes the fall of flower clusters in young trees

Turns. The element helps to increase pollen and pistachio tree ratio

It needs more trees. Symptoms of deficiency on complication and

Spooning the margins of the leaves is the hollowness of the crop and the thinness of the clusters.

Consumption of phosphorus, potassium and nitrogen fertilizers at the same time as the last irrigation

The basis of soil test and annual or infertile, increases the lifespan of eggs per year

Later and longer the pollination period
