SEEDING AND PLANTING 



per acre equals 43,560 divided by 36, or 1210. When the planting 

 is in rectangles 4 feet on one side and 6 feet on the other, each 

 plant occupies 24 square feet; therefore, the number required per 

 acre equals 43,560 divided by 24, or 1815. When the planting is 

 in equilateral triangles 6 feet on a side, each plant occupies 31.2 

 square feet; therefore, the number required per acre equals 

 43,560 divided by 31.2, or 1398. When the planting is in super- 

 posed squares 8 feet on a side each plant occupies 32 square feet: 

 therefore, the number required per acre equals 43,560 divided by 

 32, or 1362. 



Applying the above formulae, the following numbers of plants 

 are required per acre: 



In square planting: 



In rectangular planting: 



In triangular planting:
