To this should be added that the largest yield of hay from any 

 of the varieties was from the Unknown, the average for three years 

 being 5,200 pounds, or 2.6 tons. 



19. For both peas and hay, the following are shown to be 



excellent kinds : 



Whippoorwill, 

 Ked Crowder,

20. For soil improvement the varieties which produce the largest 

 yields of hay and peas combined are best and the following varieties 

 are specially desirable for this purpose : 



Unknown, 



Iron, 



Clay, 



Brown Coffee, 



Whippoorwill, 



Red Crowder,

21. The cowpea will thrive under unfavorable conditions of 

 soil preparation. It is, however, a plant that responds most readily 

 and profitably to thoroughly deep breaking and pulverization of the 

 land. This permits deep and large root development and allows 

 good circulation of the air, which together enable the plant to 

 obtain the maximum of nitrogen from the air for its growth and 

 for storing in the soil for improvement and the use of future crops. 



22. When sown broadcast or drilled with grain drill, one bushel 

 of peas makes a good seeding. Our experiments show that when 

 planted in Si^-foot rows, one half -bushel produces practically as 

 large yields as 11/^ bushels per acre. When planted in rows it pays 

 to cultivate two to three times. 



23. Cowpea-vine hay has a feeding value practically equal to 

 that of wheat bran, which is worth now more than $30 per ton. 

 Animals do not eat up the hay as clean as the wheat bran, there
