This study was undertaken to determine the effect of different work methods, types of equipment, and the size of operation on the cost of packing apples in bushel units. The information in this study was based on plants packing from 9,000 to 108,000 bushels of apples during the 1956 packing season. The data collected at these plants revealed wide variations in methods of handling and packing apples which had significant influences on the cost of packing house operations. To determine the relative influence of these factors on the cost of packing apples, each of the major packing house operations was considered separately. / Master of Science
