This is a joint progress report of cooperative investigations underway in the State
Agricultural Experiment Stations and the Agricultural Research Service of the U.S.

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 U.S. Department of Agriculture. This report is not
