June and July plantings being oftentimes too late to mature and 

 April seedings usually too early. 



It is obvious that because of the difference in the leaf area of 

 bean varieties a corresponding difference in spacing the plants 

 must be made. Experience indicates that rows of kidney beans and 

 teparies should be not less than 36 inches apart, and that the dis- 

 tance between the plants in the row should be from twelve to 

 eighteen inches. Planted in this manner, from six to nine pounds 

 of seed per acre must be provided for such varieties as Pink, Bates', 

 and Lady Washington, while, of the smaller varieties, such as 

 Tepary and White Navy, from five to seven pounds are required. 



Where soil moisture conditions are favorable it is desirable to 

 plant beans with an ordinary planter. However, if a sub-surface 

 crust appears in the soil or if soil moisture is low, planting in a 

 lister furrow is to be preferred. Beans must be planted well into 

 moist soil, if satisfactory germination is to be secured, the optimum 

 depth being usually from three to six inchees. 



Where precipitation is light and where moisture dissipating 

 conditions are particularly eft'ective, as in the Snowflake vicinity, 

 very careful attention should be given to cultivation, which should 

 be continued persistently until the flowers are setting and the plants 

 have begun to spread to a considerable extent. Especially is it 

 necessary that weeds be destroyed as quickly as possible after their 

 appearance. 



Several makes of bean hearvesters are sold by implement 

 houses. A home-made harvester, however, consisting of a culti-
