Excerpt from the report Summary: Crop production in the West has been following the national trend by increasing steadily over the years. The same major productive factors which have stimulated national agricultural output have also stimulated that in the West, but irrigation has played a more significant role in the West. Index numbers of total crop production, crop production per acre, and cropland harvested in the West since 1940 and projected to 1975 show (1) that substantial increases in total crop production have occurred during the past 20 years and that further increases can be expected, (2) that expansion of total cropland acreage will not be as important a factor in increasing future production as it has been in the past, (3) that increased yields per acre by increased irrigation and improvement in other productive factors have been and will continue to be dominant in stimulating agricultural output.
