charine sorghurrfs, also, vrhen planted in rows and cultivated pro- 

 duce a fair quality of syrup. Forage sorghums are quite easily 

 cured in this climate, but are often fed as they stand in the field. 

 The season during which their seed will germinate begins during 

 March, and continues until November. Seed does not germinate 

 promptly but the young plants grow thriftily until April of most 

 years. Little is gained by planting before the daily maximum 

 temperatures rise to 85° or 90° F., and the minimum temperatures 

 are over 45"^. They are uninjured by the warmest summer weather, 

 when they ordinarily make their best growth. They are all killed 

 when the mercury falls below 30° F., this usually occurring during 

 November. A good crop may be secured ordinarily by planting 

 any time from April to July. If the moisture supply is sufficient 

 under dry farming, the earlier planting is best; if it is not present 

 sufficiently to bring the crops up, the later planting is to be recom- 

 mended, for the summer rains usually begin then and will carry the 

 crop to maturity. 



SPINACH 



Spinach is the most popular plant grown for greens. It grows 

 with ease during the cool season if given enough water and a rich 

 soil. Mr. James Phillips, a market gardener at Globe, reports that 

 the best way to grow spinach under irrigation is to sow it broad- 

 cast in level borders and irrigate by flooding. The crowding causes 

 the plants to grow upright, which makes bunching much easier. 

 The soil must be very rich and free from weeds if this method is 

 successful. 



Prickly, Winter and Bloomsdale are the popular varieties. 



SQUASHES 



Squashes can be grown quite readily in Arizona if suitable 

 varieties are used and they are planted at the right time of the year. 

 Squashes are less sensitive to cold than melons and will germinate 

 earlier in the spring. The bush varieties will start during February, 

 and the remaining varieties will start nearty as early. As soon as 

 the frosts that usually occur in JNIarch cease, growth becomes more 

 rapid and continues until the hot weather of June. The bush 

 varieties come to maturity at this time and cease producing squashes. 

 The running varieties continue growing some longer, but growth iS 

 seriously interfered with if not stopped entirely, by the heat of mid- 

 summer. The bush varieties have ample time to produce a fairly
