Factors affecting crop yield and the number of smiling pistachios

If bone marrow laughter is due to brain growth, factors Iranian Pistachio that increase the size of the brain relative to the size of the bone skin also increase the number of smiling pistachios. Crop yield is one of these factors and the other factor is irrigation management. Both of these factors can affect the percentage of laughter. There is an inverse relationship between the yield and the percentage of smiling and hollow pistachios, so that with increasing the yield, the percentage of smiling and also the percentage of hollow decreases. Therefore, in heavy crop years, the bulk of the crop consists of unripe pistachios (reduction of marketable pistachios) and in light crop years, increase in porosity reduces the amount of pistachios available in the market.

Therefore, the percentage of smoky and hollow pistachios has a lot to do with high and low load years. The ability of the tree to maintain and mature the crop is an important factor in determining the percentage of laughter relative to the actual amount of crop on the tree in each season.
