This is a joint progress report of cooperative investigations underway in the State
Agricultural Experiment Stations and the Science and Education Administration 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 Science and Education Administration, was compiled by the Science
and Education Administration, U.S. Department of Agriculture. This report is not
intended for publication and should not be referred to in literature citations nor
