Under certain agricultural programs; that quantity of a commodity that will provide adequate and normal market supplies. When marketing quotas are in effect (only after approval by two-thirds or more of the eligible producers voting in a referendum), growers who produce in excess of their farm allotments are subject to marketing penalties on the "excess" production and are ineligible for government price-support loans. Quota provisions have been suspended for wheat, feed grains, and cotton since the sixties. Rice quotas were abolished in 1981. Poundage quotas are still in use for domestically consumed peanuts, but not for exported peanuts.
