Pistachio seed sowing methods

In fields with fresh water and soil, the germinatedIranian Pistachio seeds intended for sowing are sown in the place of the main land after the soil has been plowed (reaching the field capacity). If the field soil is heavy, the inside of each pit is covered with sand in order to seal the seeds. This helps the plant to grow, because not only does it provide enough oxygen to the roots of the seedlings, but it also activates the beneficial aerobic organisms in the soil. The depth of seed sowing depends on the size of the seed (planting depth is about 2 to 5 times the diameter of the seed) In Iran, pistachio seeds are sown in two ways.
The first method of sowing pistachio seeds:

Sowing seeds in plastic pots in the greenhouse is at the end of September or the first of March. The seedlings are transferred to the main land after one year of growth in the greenhouse.
In the second method of planting pistachio seeds:

Seeds are sown directly in the ground in mid to late April. Some gardeners think that direct sowing of seeds in the mainland, although delayed in growth compared to potted seeds, will result in stronger plants than potted seedlings after a few years.
Planting pistachio seeds in the treasury:

The ground of the pistachio treasury, like the treasury of other trees, must be prepared. The distance between sowing seeds on the planting bed is between 5 to 10 cm and between lines 35 to 40 cm. After sowing the seeds, they are covered with aerated sand along with livestock manure and irrigated. The amount of pistachio seeds used in pistachios is 250 to 300 kg per hectare and about 250,000 pistachio seedlings can be produced per hectare.

Produced seedlings are ready to be transferred to agricultural land in autumn and winter (annual seedlings). The higher the age of pistachio seedlings in the treasury, due to the expansion of the root system and the complexity of the roots of pistachio seedlings and the inaccuracy in moving the seedlings to agricultural land and cutting the roots, it is done at once.

Corridors are built in the treasury at distances of 1.5 to 2 meters, which helps workers move to remove weeds and carry out irrigation and grafting of seedlings. If the floor of the treasury is carpeted with cement or mosaic, it prevents the roots from growing downwards. Therefore, the seedlings will be easier to move and their losses will be less.
