grain was badly shrunken because of insufficient moisture in late

SORGHUMS 



The .sorghums are well adapted to Sulphur Spring Valley con- 

 ditions, being able to withstand long periods of drought, and to re- 

 cover and resume growth when the moisture supply is again abund- 

 ant. That sorghums are surer crops for dry-farming than corn is 

 illustrated by results from one plot each of Early Amber sorghum 

 and Half Dent Drought Proof corn, which, when grown together 

 in 1914, produced at the rate of 360 pounds of heads and 260 pounds 

 of stover per acre and Z7 pounds of ears and 161 pounds of stover 

 per acre, respectively. The soil in these plots is approximately two 

 feet deep. During the latter part of August and September it was 

 quite dried out. In October when moisture had again become 

 ample the sorghum revived after much of the corn was dead. 

 Under continuous growing conditions, however, corn often yields 

 more than sorghums, as illustrated by results from two adjacent 

 plots of Feterita and Mohave corn, grown, in 1914, on clay loam 

 soil underlaid by a clay subsoil, which retained sufficient moisture 

 to keep both crops in a growing condition throughout the dry 

 period. The corn yielded at the rate of 1364 pounds of ears and 

 1672 pounds of stover per acre, while Feterita produced 1085 

 pounds of stalks. 



Six varieties of grain sorghums were planted in July, 1914. 

 Best yields were obtained from plots of Feterita and Dwarf milo. 

 Shallu and Black-hulled White Kafir both failed to mature because 

 of the shortness of the frost-free season remaining after they were 

 planted. See Table LXXXVIII. 



Seven varieties of grain sorghums were planted in 1915, on 

 dates ranging from April 23 to July 31. The best yield was ob- 

 tained from a plot of African Kafir planted May 25. The next 

 highest yield was from a plot of Standard Milo which, however, 

 failed fully to mature. 



All grain sorghums in 1916 were grown for ensilage, best re- 

 sults being obtained from a plot of Dwarf Kafir planted March 17. 



Two varieties of sweet sorghum. Club-top and Early Amber, 

 were planted in July 1914. See Table LXXXIX. Club-top failed 

 to mature but yielded satisfactory quantities of green forage. One
