Walnut Orchards in Azerbaijan: How to Plan, Establish and Manage Efficiently

Walnut needs deep, fertile, well-aerated soil; the Ministry of Agriculture advises against saline soils and sites with high groundwater. Water decides the rest: irrigated land produces over 80% of Azerbaijan's agricultural output, and annual rainfall ranges from 150 to 200 mm on the Absheron Peninsula to 1,400 to 1,600 mm in the mountains (World Bank and Asian Development Bank).

Azerbaijan mainly grows varieties such as Seyfi, Sugra, Araz, Disar and Ideal, and the Ministry of Agriculture also considers a number of introduced varieties promising. Most varieties do not come true from seed, so orchards are planted with grafted trees. Choose varieties for your target market and plant compatible pollinizers.

For tall-growing trees, the Ministry recommends a spacing of 10 to 12 m by 8 to 10 m, with plantations divided into blocks of 15 to 20 ha. Put the wider distance between rows: that layout suits mechanized harvesting, provided headlands, access lanes and clean, straight trunks leave room for shakers, sweepers and harvesters.

The Ministry of Agriculture's reference for walnut is three to four irrigations per season and nitrogen, phosphorus and potassium at 60 kg of active ingredient per hectare, which it says considerably increases yield. Adjust both to soil tests, leaf analysis and the rainfall of your district.

Spraying must reach the full height of mature walnut trees. The Mañez Lozano Mega Twister S6 is designed for taller trees and denser canopies, while ID DAVID machines cover in-row weeding, manure spreading, and side pruning and topping up to 4.9 m; OVE Europe sells both brands in Azerbaijan.

Floor care decides harvest quality. In young orchards the Ministry recommends keeping tree rows and inter-rows weed-free; in bearing orchards, keep the floor level and firm, cut the grass short before harvest and remove prunings, so sweepers and harvesters collect clean nuts.

In Azerbaijan, walnuts are harvested in autumn, once most hulls have split; timing depends on site, altitude and variety. At the Shaki-Oghuz Agropark, the harvesting and drying period is put at 40 days (president.az). Scattered trees can be picked by hand, but across hundreds of hectares, harvest capacity and speed decide quality and cost.

Flory harvesting machinery is already working in Azerbaijan. A typical Flory on-ground set starts with the VR700 Shaker, followed by a V62 Sweeper that moves nuts into windrows and the self-propelled 8772 Harvester, which picks them up with low dust. A 1500 Conveyor Cart, ST14 Shuttle and 4840 Field Elevator then carry the crop to the trucks.

Plan capacity so nuts are picked up the same day they are shaken: University of California research shows walnut quality starts to fall within hours. Drying in the sun darkens the kernels (UC ANR), so move the crop to hulling and controlled drying rather than leaving it on open ground.

Large orchards are investing in processing: when its foundation stone was laid in 2022, the walnut plant at the Shaki-Oghuz Agropark was planned to hull, wash, dry, sort and pack nuts to international standards (President of Azerbaijan website). Whatever the scale, hull and wash on the day of harvest, remove blanks and defects, then start drying.

Dry gently and completely. University of California guidance is about 8% moisture with air no hotter than about 43 °C. Nuts that are not fully dry are prone to mould and quickly turn rancid, while cool storage keeps quality: at about 4 °C, in-shell walnuts keep for a year (UC ANR).

Jessee, whose processing lines OVE Europe supplies, builds hulling, drying, in-shell cleaning and sizing, and cracking equipment for walnuts, with standard hulling systems from about 10 to 30 tons per hour. Grading by size and kernel color helps domestic walnuts compete with imported product.
