its more upright habit of growth, is better suited for these mixed 

 plantings than the cowpea. Nearly as much hay is obtained from 

 the Sudan grass alone as from the mixed seedings, but the addition 

 of a legume to the hay adds to its value by increasing the protein 

 content.

The proper proportion of Sudan grass and legumes in the mixtures 

 has not been determined, but a mixture containing three plants of 

 Sudan grass to one plant of the legume is theoretically obtained by 

 sowing 10 pounds of Sudan grass with 50 pounds of cowpeas, 12 

 pounds of Sudan grass with 60 pounds of cowpeas, or 16 pounds of 

 Sudan grass with 80 pounds of cowpeas. The total weight of seed 

 used can be regulated according to the wishes of the planter and the 

 fertility of the soil. The proportions of Sudan grass and soy-bean 

 seed can be made the same as those with cowpeas. Generally speak-
