Excerpts from the report: Farmers market most of their peanuts during a 2-month period following harvest and field curing. Shellers, crushers , and other dealers or handlers (including Commodity Credit Corporation) then store this crop as farmers stock for periods ranging usually from 2 to 8 months. This crop is usually stored in the areas where produced. Storage of farmers stock peanuts presents several economic problems such as excessive loss of weight and quality due to loss of moisture, kernel damage, and insects and rodents. The immediate problem is to determine the changes in quantity and quality of peanuts occurring during storage and the extent of the loss due to the various factors. This study was designed to evaluate the economic significance of changes in quantity and quality of farmers stock peanuts occurring during storage under varying conditions.
