Experimental Work in Dry-Farming

PeauMts: A plot of peanuts was planted May 20, 1915, but rab- 

 bits ate them off as fast as they came up. They were quite per- 

 sistent, however, and are interesting as a possible forage crop for 

 Sulphur Spring Valley dry-farms. 



Szveet Clover: A very few plants of sweet clover were pro- 

 duced in 1914. Three of these were transplanted, and in 1915 each 

 } ielded about one pound of seed. Sweet clover planted in 1915 

 failed entirely, due, largely, to drought in spring and a too loose 

 seed bed. 



Lcspcdcza: Lespedeza or Japanese clover was planted in the 

 spring of 1915 but failed to germinate because of di ought. 



Vetch: Spring vetch produced but few inferior plants in both 

 1914 and 1915. Winter vetch was planted October 8, 1914, and 

 gave promising results. The yield of approximately five tons of 

 green forage per acre was plowed under for fertilizing purposes on 

 June, 1915. 



SUMMARY OE SULPHUR SPRING VALLEY DRY-E.\RM D.\TA 



Alfalfa, grown in rows and cultivated, may be made to pro- 

 duce a fair crop of seed. 



It is difficult to obtain a satisfactory stand of beans planted 

 before the summer rains. Early varieties of beans may be planted 



Fig". 46. — Dry-farmed late cowpeas. Grown near Cochise, Arizona.
