A FARM MANAGEMENT SURVEY IN BROOKS CO., GA.

secured when enterprises are combined in different proportions will 

 help to show the proportions that are best adapted to the local con- 

 ditions. Such a study has been made for the important crops found 

 on the farms surveyed, and the results are presented in Table XVI. 

 The index of earnings and the per cent returns on investment are 

 the measures of efficiency used.

Reference to Table XVI will show that the farms with from 20 to 

 30 per cent, or an average of 25 per cent, of the crop land planted 

 to cotton, gave higher returns than did those with either a larger or 

 smaller proportion than this. Thus, the farms with no cotton planted 

 returned farmers' earnings amounting to $372. As the percentage 

 of the crop land in cotton increased, up to 25 per cent, the farmers' 

 earnings increased to $1,112. But a further increase in the propor- 

 tion of land in cotton resulted in lower earnings, amounting to $721 

 for the group of farms with the largest proportion, or over 40 per 

 cent of the land in cotton. 



Expressed in another way, the farms with no cotton returned 

 farmers' earnings amounting to but 70 per cent of the average of 

 farms of a similar size. With increasing proportions of cotton 

 planted, up to 25 per cent of the crop area, the returns increased to 

 28 per cent above the average, but decreased to 86 per cent with a 

 still further increase in the proportion of cotton.
