A fully mature tree can produce up to 50 pounds of dried, shelled nuts. Trees begin to produce in 5 to 8 years, but full production is not reached until they are 15 or 20 years old. Pistachios tend to produce every other year, producing a bountiful harvest one year, followed by little or no harvest the next. The average pistachio with buds usually bears fruit in the fourth or fifth year of life.
Production at this early age usually ranges from 2.2 to 4.4 pounds. For medium production, 7 to 10 years are required. At this age, fair production ranges from 13 to 22 pounds. When trees bear fruit, between the ages of 12 and 14, the production of a healthy, well-maintained pistachio can reach or exceed 33 pounds.
The amount of pistachios a pistachio produces depends on many factors. The tree's age, health, location, soil, nutrients, water, sunlight, temperatures and more influence the amount of nuts a tree produces. On average, a tree grown in a commercial orchard should produce 15 to 20 pounds of nuts once it is fully mature. When a pistachio tree is young, yield ranges from 2.2 to 4.4 pounds of dried walnuts or 5.5 to 11 pounds of fresh walnuts.
As your tree ages (7 to 10 years old), expect production to be around 13 to 22 pounds of dried walnuts or 33 to 55 pounds of fresh walnuts each year. The yield of pistachios depends mainly on the climate, the crop (variety) and crop management practices. On average, a yield of 8 to 10 kg can be obtained per fully mature tree (after 10 to 12 years of budding). Roasted pistachio seeds may turn red artificially if they are marinated before roasting them in a salt-strawberry marinade, or in salt and citrus salts.
Your family will love sitting in the shade of your pistachio tree, and they'll love having access to fresh pistachios whenever they want. If old leaves and fruits remain on the tree during the dormant period, they need to be removed to prevent diseased plant material from moving on to the next season. Most pistachios are now machine-harvested and the shells remain intact, so there is no need to dye them, except to meet deep-seated consumer expectations. Pistachio is one of the culinary nuts cultivated in most countries and belongs to the cashew family.
Weed control is another task in pistachio production for healthy tree growth and quality nut production. Commercially grown pistachio plantations are usually highly productive for about 40 to 50 years once the trees have matured, provided that they are properly cared for. Pistachios require full sun, so growing pistachios need at least 6 hours of sunlight to achieve optimal growth. Since pistachios split before harvest, do not allow them to fall to the ground to reduce the risk of contamination.
Each pistachio should receive 450 grams of ammonium sulphate in 2 divided doses during the growing season. Pistachio, a member of the cashew family cultivated by Plantations International in Greece, is a small tree native to Central Asia and the Middle East. If anything hard is found in the top 6 to 7 feet above the ground, it should break, as pistachios have deep roots in nature and these trees are affected by water stagnation. Since nitrogen is an important fertilizer for any nut crop, pistachios have a nitrogen requirement similar to that of other nut trees.
If the growing pistachio blossoms turn black and fall off the tree, look for larvae and adult borer moths. Two signs that pistachios are ready to harvest are when the shell takes on a reddish color and when the shell splits and reveals the shell underneath. .
