BULLETIX 636, U. S. DEPARTMENT OE AGRICULTURE. 



it costs slightly over 1 cent more per box for the mulch-crop than 

 for the clean-cultural orchards. This difference in cost is princi- 

 pally due to the greater fixed costs on the mulch-crop orchards. It 

 will be seen from Table XVI that the percentage of the various costs 

 which go to make up the total cost is nearly the same in both kinds 

 of records.

If the material and fixed costs are combined, the cost of the clean- 

 cultural orchards is 56.15 per cent and of the mulch-crop 57.36 per 

 cent of the total annual net cost of production. It is thus apparent 

 that the cost of production varies but little under the two systems 

 of management. 



Seventy-one cents per box may be considered a fair figure for the 

 cost of production in Payette Valley under normal prices for labor 

 and material. 



FACTORS AFFECTING THE ANNUAL COST OF PRODUCTION. 



The principal factors which affect the cost are the same for Payette 

 Valley as for all other apple regions studied thus far. The one which 

 has the greatest effect upon the cost per box is the yield per acre. Table 

 XVII serves to show the cost of production per acre and per box. 

 Orchards having various yields are divided into 10 groups ranging 

 from 122 to 572 boxes per acre in yield. The maintenance cost is 

 found to remain practically the same per acre in the case of the high 

 yields as in the case of the low, but the maintenance cost per box 

 very materially decreases as the yield per acre increases. The hand- 

 ling and material box costs are little influenced by the yield, 

 while the fixed cost, although remaining much the same per acre,
