Relation of Weather to Crops 77 



All varieties of barley do well. The variety of oats most widely 

 grown is Texas Red. 



For winter pasturage and an early crop of hay, barley, wheat, 

 and oats are grown instead of the grasses used in cooler regions. 

 These grains are sown both upon the fields of alfalfa and in freshly 

 plowed soil. In the former case the seed is covered with a disk 

 harrow. In fresh soil the seed is either disked or harrowed in. 

 When sown upon alfalfa fields, seeding is usually done during early 

 fall. In fresh soil seeding is done throughout fall and early winter. 

 The resulting growth is commonly pastured during winter, and then 

 permitted to grow up for hay during spring, being cut in April 

 and May, when the kernels are quite well formed. Oats make 

 the best hay, and they are now sown for this purpose more gen- 

 erally than formerly. The usual yield of grain hay is one and a 

 half to three tons per acre. 



GRAIN SORGHUMS 



The sorghums are divided into two classes — the saccharine, 

 used for syriip making or for forage, knd the non-saccharine or 

 grain sorghums, used for grain and forage. 



The grain sorghums are of tropical origin, and flourish best in 

 hot climates. They are very drought resistant, and well adapted 

 to the semi-arid Southwest. They develop well with eight to ten 

 inches of rainfall during the growing season. 



Grain sorghums are divided into three classes, according to the 

 character of head: 



1. Kafir, with compact, erect heads. 



2. Durra, with compact, pendant heads. 



3. Broom corn type, with loose spreading heads. 



The varieties of grain sorghums profitably grown in Arizona that 

 belong to these classes are as follows: 



Black-hull white Kafirs, dw^arf and standard. 

 White milo or durra. 



\ ellow milo, usually called Milo Maize, dwarf and standard. 

 Feterita, one of the Durras. 



. Shallu, a broom corn type, sometimes called Egyptian wheat. 

 Kowliang, another broom corn type. 



Kafir 



The Kafirs, of which there are three varieties, the White, the 

 Red, and the black hulled White, are very drought resistant. They
