 This is a joint progress report of cooperative investigations underway in the State 
 Agricultural Experiment Station and the Agricultural Research Service of the U.S. 
 Department of Agriculture containing preliminary data which have not been sufficiently 
 confirmed to justify general release; interpretations may be modified with additional 
 experimentation. Confirmed results will be published through established channels. The 
 report is primarily a tool for use of cooperators and their official staffs and for those 
 persons having direct and special interest in the development of agricultural research 
 programs.
 
 This report includes data furnished by the State Agricultural Experiment Stations as well 
 as by the Agricultural Research Service was compiled by the Agricultural Research Service 
 U.S. Department of Agriculture. This report is not intended for publication and should 
 not be referred to in literature citations nor quoted in publicity or advertising. Use of
