The California Walnut Commission plans to vote on raising the cap on how much growers can pay in assessments to promote walnuts.

The current assessment cap is $0.01 per inshell pound. The increase would raise the cap to $0.0175, according to a news release.

The vote will not determine the actual assessment, which is decided each year by the commission board members.

The cap can only be increased by a vote of the growers.

For the past 25 years, the assessment has been below the cap 12 times, including in 2011, according to the release.

The California Department of Food and Agriculture plans to mail ballots on March 2. Growers have 30 days to respond.
