were introduced from South Africa and will endure for extended 

 periods awaiting rainfall, without apparent injury to the plant. As 

 soon as moisture is supplied Kafir will renew its growth and continue 

 to mature its grain. The growing season for Kafir is about 120 

 days, or longer when growth is arrested by insufficient moisture. 

 The date of planting in both irrigated and dry-farming sections 

 should be as early as late spring frosts will permit. Under dry- 

 farming conditions in the southern part of the State it is well to 

 put the crop in as early as March 10 to 15 in order to take advantage 

 of winter moisture. 



Black-hull White Kafir is the most popular variety grown in 

 Arizona both for grain and silage purposes. 



Milo Maize 



The term Durra is so little used that this group is considered as 

 Milo Maize. The Durras include white, brown and yellow miles 

 and are characterized by large flat seeds. Feterita, a more recent 

 introduction, also belongs to the Durra group. 



This group of grain sorghums was introduced from North Africa. 

 Like Kafir, Milo Maize flourishes in the hot dry climate of Arizona. 

 The time required to produce a crop of yellow milo is about 100 days 

 or nearly three weeks shorter then Kafir. The Milos are better 

 grain producers than the Kafirs, but are not as good forage crops. 



Dwarf types of milo have been developed superior to the tall cr 

 standard types for production of grain. Under dry-farming condi- 

 tions the Milos should be planted in July in southern Arizona. The 

 summer rains begin at this time and the season is long enough after 

 that date to mature a crop. In the northern part of the State, where 

 these crops are grown by dry-farming, planting should be made 

 about May 1. 



In the irrigated sections the Milos should be planted in April. 

 Two crops of milo can be harvested from the April planting. The 

 first crop can be cut in early July and used for forage or silage, and 

 from the stumps a second crop will be produced before the frosts 

 in November. 



Feterita 



Feterita is a variet}' of Durra with erect heads, white seeds and 

 black hulls. This variety is of recent introduction and shows super- 

 iority over the Kafirs in drought resistance, and in shorter length
