Table XV shows the distribution of costs on cotton when different 

 yields per acre are obtained. The cost of each crop of cotton on the 

 114 farms was computed separately, so that the averages are for 

 crops and not for farms. The average number of days of man labor 

 per acre increases with the yield, due to the increased amount o'f 

 labor required for picking. However, the increase in yield from 

 170.3 pounds to 314.6 pounds is 102 per cent, while the increase of 

 man labor is only 41 per cent. The average amount of horse labor 

 required per acre for the crops making the lowest yields is 3.12 days, 

 while on the crops making the highest yields the number of horse 

 days required is 3.34. This is an increase of onl} r 7 per cent. This 

 table further shows that the rent per acre increases as the yield in- 

 creases. The rent of crop land making yields of 170.3 pounds is 

 $4.72, while that of the land making a yield of 344.6 pounds of lint 



is $5.80. 



is an in- 

 man labor 

 acre from 

 the crops 

 making low 7 }nelds to 

 $12.80 on crops of 

 high yields, being an 

 increase of 46 per 

 cent. There is a 

 slightly greater in- 

 crease than in the 

 number of man days 

 required per acre on 

 the same farms. There is scarcely any increase in cost of horse labor 

 as the yield per acre increases. 



The ginning cost, being a charge based directly on the quantity of 

 cotton, increases directly with the yield. 



The total cost of lint per acre increases 33 per cent, while the 

 increase in value is 102 per cent. The yield per acre increases more 

 rapidly than the cost per acre, so that as the yield increases from 

 170 pounds to 344.6 pounds the cost per pound decreases from 10.5 

 cents to 6.7 cents. 



The same results were found for corn as for cotton, with only very 

 slight variations. Figure 11 and Table XVI show the relation be- 

 tween yield per acre and the cost per bushel. When corn yields less 

 than 18 bushels per acre, the cost is greater than the market value, 

 The average yield of corn for the region was 25.6 bushels per acre 

 at an average cost of 58.4 cents per bushel. As the yield increases 

 beyond the average the cost continues to decrease, but not as rapidly.
