are grown. On and contiguous to the parallel of 45, the 

 early dwarf varieties of the soy bean may be planted. 

 Between the parallels 38 and 45, the medium dwarf, in- 

 cluding such varieties as the early white, will be found 

 suitable, also the medium early green, a variety that has 

 found favor in certain sections of New England. Farther 

 southward the standard varieties are more suitable. 

 These include the medium late green and the medium late 

 black. It is unsafe to plant either class of the two classes 

 before the danger from spring frosts is past. When frozen 

 down, the plants do not recover satisfactorily, as in the 

 case of corn. This will mean that near, the Canadian 

 border planting will not be safe before about June 1st. 

 The season for planting will continually advance as the 

 north is receded from, save in certain areas of high alti- 

 . tude. The soy varieties should not be planted until both 

 soil and weather have become reasonably warm. 



Both classes may be planted in hills or in rows, but 

 the latter method is the one that is most commonly 

 adopted. The work may be done with the corn planter 

 or with the grain drill. The distance between the rows 

 and plants in the row will vary with the size of the 

 plants of the particular variety. More commonly the 

 rows are made 36 inches apart for the small varieties of 

 both classes of beans. For some varieties of the soy 

 beans the distance should be greater. The space between 

 the plants will vary as the plants are large or small. 



The depth to plant in average soils is from 2 to % l / 2 

 inches, but in very loose soils or in those without mois- 

 ture near the surface, it may be necessary to plant more 

 deeply. 



The amount of seed called for will vary much with 

 the size of the seed. Usually from 2 to 3 pecks will suf- 

 fice per acre, and in very dry conditions a less quantity 

 will answer.
