Results of 1968 Tests Indicate that Substantial Reductions in Yield of Green Asparagus can be Expected with Selective Mechanical Harvesting, as well as with Nonselective Harvesting. Under Present Conditions a Grower's Net Profit Would be Reduced if he Changed from Hand Cutting to Either System of Mechanical Harvesting. A More Detailed Report on these Tests is Available, Upon Request, from the Department of Agricultural Engineering, University of California, Davis.

R. E. Michaud, Field Test Engineer, Hart-Carter-Pacific Corp., assisted in the tests. Hamatani Farms, Inc., Courtland, California, cooperated.
