In Table III the farms are divided according to the percentage 

 of the rotation area that was in summer fallow. Of the 68 clay 

 farms, 1 1 had no smnmer fallow, 29 had 25 per cent or less, and 28 

 had over 25 per cent of the rotation area in summer fallow. Of the 

 144 silt loam farms, 127 had no summer fallow and 17 had more or 

 less summer fallow. Using as a measure the percentage farm in- 

 come is of the capital, it will be seen that the groups of farms having 

 no summer fallow were operated most efficiently. By dividing 5.83 

 by 3.41 it will be seen that the clay farms having no summer fallow 

 were 1.71 times as efficient as those having over 25 per cent of the 

 rotation area in summer fallow. Likewise the silt loam farms having 

 no summer fallow were 1.66 times as efficient as the farms having 

 summer fallow. Hence, efficiency on these farms may be increased 

 by adopting cropping systems and rotations which will decrease the 

 acreage in summer fallow. 



INCOME PEE PRODUCTIVE ANIMAL UNIT. 



Where crops are grown and fed to live stock on the farm, few 

 factors have as great an influence as income per productive animal 

 unit. Although a farm produces excellent crops, it may still be low 

 in efficiency if the crops produced are fed to live stock of inferior 

 quality or if poor judgment is used in marketing live stock and live- 

 stock products.
