Quite a number of queries reach the Botanical Section with reference to the quality of clover, alfalfa, alsike and timothy seeds.
The tests made show considerable variation. Many new seeds are being introduced with impure seed. The vitality in some cases is low.
There is great need that farmers should buy only seed which has been tested for germination and purity. If you want your seed tested without cost send small samples (2 ounces) to the Botanical Section of Iowa State College, Ames, Iowa.
