must be applied whenever needed, so that they may 

 suffer no set-back because of intense dry spells. Peas and 

 beans finish most of their growth hi spring and early sum- 

 mer, when there is usually an abundance of water. Just 

 before and at the time of blooming the largest quantity 

 of water is required. When the pods are pretty well 

 formed little water is required, and soon afterward 

 irrigation may be stopped altogether. In fact, a somewhat 

 dry soil, after the pods are well formed, helps in the 

 formation of the seed. Peas, which require less water 

 than beans, when grown for seed require only one irriga- 

 tion; when grown for fodder, two or three irrigations may 

 be applied. It is often profitable to grow two crops of 

 peas. One is harvested early in July and the other hi 

 early fall. 



The Wyoming Station has conducted experiments 

 on the quantity of water used by peas. Some of the 

 results obtained are shown hi the folio whig table: 



The quantity of water used varied from none to 

 22.92 inches. The acre yield of forage varied from .66 

 tons to 4.20 tons. The total acre yield of peas varied from 

 three bushels to nineteen bushels. The percentage of 

 peas hi the whole crop varied from 14 to 37. The yield 

 did not increase so rapidly as the water increased. The
