This is the earliest Yamhill variety hazelnut orchard in the State of Oregon. Yamhill is a newer, an illness resistant variety developed by Oregon State University. The orchard is own by Birkemeier ranches of Canby, OR.

Few realize the Oregon to produce 99 percent of the hazelnuts in the unified States. That means that specific forecast the hazelnut manufacturing in the Beaver state assists the industry in determining marketing plans and also price. To perform that,’s National farming Statistics company runs a joint task with the Hazelnut Marketing plank of Oregon, which allows us to measure the most accurate manufacturing yields and also forecasts for hazelnut production possible. This job is dubbed the Oregon Hazelnut Objective yield Survey.

When it involves forecasting manufacturing of a particular commodity, there room various approaches we deserve to use. Predominantly we inspection growers to get their calculation of their own farm production. We combine the farmers’ responses through objective yield measurements. In brief, we use the objective yield survey to count and also measure the chop prior come harvest so the we can see what sort of crop we have the right to truly expect by the end of the growing season.

To conduct the Oregon Hazelnut Objective productivity Survey, we randomly pick hazelnut orchards that stand for the bearing acreage in ~ Oregon. Factors we store track of encompass the age of trees and also variety. As soon as an orchard is selected and also the producer sponsor permission to enter an orchard, the national Association the State department of agriculture (NASDA) enumerators randomly select trees and also branches indigenous which to choose the nuts and send them come our activities for processing.

Enumerator Brandon Jordan measure up a branch throughout the branch choice process.

Once in the lab, nuts room counted and also samples space selected come peel turn off the husk. Us then measure the size of the nut and also crack it open to identify if a kernel is within the shell. All outcomes are entered in a computer and also summarized. That sounds basic but careful steps are taken along the method to ensure all recorded procedures are followed consistently. The target yield analysis helps ground-truth the survey and builds an accurate picture of the upcoming harvest.

Pest and weather results have make this job-related more daunting in current years, however by following constant procedures ours results administer solid, target statistics that those interested in hazelnut production deserve to rely on.

We conduct all these dimensions from 180 different orchards throughout the an initial two main of August. Due to the fact that the results have actually such a strong impact top top the hazelnut industry, us make sure the data are published as soon as possible. The culmination of all these efforts was the report because that 2016, in i beg your pardon we estimate Oregon hazelnut production for 2016 to it is in 38,000 tons. If realized, this will be a 23 percent increase from the 31,000 tons developed last year and over the five-year mean of 37,200 tons.

Lab supervisor Tim Zielke and Enumerator Stephanie Zielke ar hazelnuts in a sizing network to recognize the size of the nuts.
