 METHODS AND TIME OF PLANTING ALFALFA. 



In 1911 an experiment in methods and time of planting alfalfa was 

 started on 13 one-fourth-acre plats in field A-IV. The experiment in- 

 cluded early and late plantings, planting early with w'heat as a nurse 

 crop, and planting in rows 18 inches apart to be cultivated. The 

 rate of seeding of alfalfa was 12 pounds per acre, except in the row 

 plats, where it was 6 pounds per acre. In the nurse-crop plats wheat 

 was planted at the rate of 1 bushel ])er acre. Table IV shows the 

 yields obtained in 1911 and 1912 from planting by the different 

 methods.

It is seen that early planting has resulted in somewhat higher 

 yields than have been obtained from late planting. The yields 

 secured from the row planting are noticeably low. In comparing 

 these results with those obtained by planting the alfalfa with a nurse 

 crop of wheat, consideration must be given to the yields of wheat and 

 of wheat hay, as shown in Table IV. It will be noted that the alfalfa 

 yields in 1912 on the imrse-crop plats were but little lower than those 

 obtained where the alfalfa was planted alone.
