Foliar application of pistachio trees in pistachio shell the post-harvest periodIn short, 4 elements should be sprayed in the post-harvest period of pistachios. These 4 elements include nitrogen (N), zinc (Zn), boron (B), calcium (Ca). Of these, zinc (Zn) and calcium (Ca) are more important than others in foliar application. Although nitrogen or nitrogen can be considered the most important element required for pistachio trees in the post-harvest period, but because nitrogen fertilizer is usually applied to the soil through the soil and before the first irrigation in the post-harvest period, it is less important in foliar application. Be.
After harvesting, it is necessary to apply nitrogen fertilizers and ammonium sulfate or urea or a mixture of these two fertilizers can be used. Calcium plays a very important role in post-harvest foliar application and research has shown that foliar application of calcium fertilizers in the post-harvest period is very beneficial. The elements zinc, nitrogen and boron can be used in combination in the post-harvest period. Zinc is the precursor to auxin (growth hormone) in trees, and if sprayed in the post-harvest period, the trees will grow better in the spring of next year than trees that have not been sprayed.
