BULLETIN 943, U. S. DEPARTMENT OF AGRICULTURE. 



high charge for contract labor in Keith County, Nebr., was largely 

 due to the great amount of grain hauled to market by contract 

 labor, this being 66 per cent of all that was produced. 



In some districts considerable work was done with tractors. 

 Unless contract work, the man hours for operating the tractor were 

 included under labor costs; but obviously no cost for horse labor 

 would occur. The maintenance and upkeep cost of the tractor have 

 been charged under machinery costs and not as hours of tractor 

 labor. 



The great variations in average labor costs, by counties, as shown 

 in Table XXI, are due to the variation in man and horse labor rates 

 used in calculating labor costs, and to the variations in amounts of 

 labor devoted to raising an acre of wheat. As previously shown, 

 considerable variation existed in the average labor rates determined 

 for various counties. However, it does not necessarily follow that 

 those counties having the higher labor rates had the higher total 

 labor costs per acre.

MATERIALS. 



SEED. 



The most common variety of seed wheat for the spring-wheat 

 districts was the Marquis, and for the winter-wheat districts the 

 Turkey Red. An average of approximately 3.5 per cent of the 

 winter-wheat acreage was reseeded, while no reseeding was required 

 for spring wheat.
