Table YII serves to show normal times for the different kinds of 

 tools of standard make and width. It was found that the average 

 annual cost of cultivation, including plowing, is $11.74 in the case of 

 the clean-culture orchards and $1.41 in the case of the mulch-crop 

 orchards, which receive a thorough cultivation about once every 

 three years.

As is shown in Table VIII, there is a difference in cost for all 

 cultivating time of $7.30 per acre, or $0,031 per box, in the favor of 

 the mulch-crop system, but this difference is largely offset by the 

 cost of irrigating on the latter orchards. 



MULCH CROPS. 



There are two kinds of mulch or shade crops used in the valley, 



namely, clover and alfalfa. (See fig. 9.) They are usually sown 



alone, although in some cases the orchard may be in both clover and 



alfalfa. Of the 21 orchards in mulch crop, there are 12 in clover, 8
