40 CORN 



3. Detassel corn to prevent self-fertilization. Go into the 

 ear-to-the-row test field just at the time when the tassels are 

 beginning to show. If the sheath which incloses the tassel is 

 pinched several inches beneath the top of the tassel, we can 

 readily remove the tassel from the plant by pulling it out. 

 Every alternate row is treated in this way so that one half of 

 the rows in the test will be detasseled and the other half will 

 bear tassels. The tassel-bearing plants will fertilize the silks 

 on the detasseled plants, and also those on the tasseled plants. 

 The seed should be retained from the detasseled plants upon 

 which a cross has been forced. If any inferior or barren plants 

 are found in the tasseled row, pull them up or detassel.
