Hazelnuts, also called filbert, cobnut or hazel, are in the genus Corylus, which is comprised of about 15 species of shrubs and trees in the birch family (Betulaceae) and the edible nuts they produce. The plants are native to the north temperate zone. Turkey produces the most globally consumed hazelnuts. Hazelnut is a wind pollinated fruit; the pollen will then lay dormant for seven to eight months. The Willamette Valley in Oregon produces 99% of the US hazelnut crop.
Nut set is categorized as the critical transition period shortly after fertilization as plant processes switch over to nut formation and growth. A successful nut set is integral to a healthy crop at harvest. This process can be improved with the addition of Cytokin® at key timings. Cytokin® contains plant growth hormones responsible for cell division, cell enlargement, and various other plant growth functions. The nature-based plant growth regulator effects help to maximize conditions necessary for nut set and early development.
Cytokin® is a plant- based EPA registered plant growth regulator designed to increase crop production efficiency.
Nut Fill is an important and nutritionally taxing period within a plant. Phosphorus and potassium are critical nutrients required at this time, as they are responsible for translocation of proteins and sugars, water balance in the plant, production and utilization of ATP, root development and many other processes. The proprietary humectant system provided by Sugar Express® enables increased absorption and translocation of nutrients during this stage.
Sugar Express® 4-10-40 is a highly refined fertilizer with the appropriate ratio of phosphorus and potassium designed to be used close to harvest.
