SMALL SEED IMPROVEMENT
All progressive farmers are now taking a keen interest in seed improvement, since due attention to this factor of crop production has been found to very materially increase yields of field crops.
Clover, alfalfa, and other forage crops are grown fairly extensively in Indiana. Much more of the leguminous crops, however, should be produced, since they are valuable stock foods and soil improvers.
Clover, alfalfa and grass seeds being so small, and the impurities and adulterants, apt to occur in them, so numerous, it is extremely difficult, without some study and practice, to accurately estimate the real value of various lots of these on the market and elsewhere. To assist all interested in these seeds, a Branch Seed Laboratory has been established by the Bureau of Plant Industry, U. S. Department of Agriculture, in cooperation with the Agricultural Extension Department, Purdue University, LaFayette, Ind.
Examinations, tests, and identifications of all small seeds, both field and garden, are made in the Laboratory and reports furnished promptly, without charge.
In the light of experimental and other evidence, it is now known that it pays well to use sound, pure, clean, vigorous seed on Indiana farms.
Have your seed tested!
