Mid-April prices received by California farmers were unchanged for all types of hay and other hay. Prices for all potatoes and fall potatoes were below the previous month's level. Mid-month prices for wheat and dry edible beans were not published to avoid possible disclosure of individual operations. There were insufficient sales to establish a mid-month price for barley. Prices were above a year earlier for alfalfa hay.
