CROPS THAT MAY BE GROWN IN DRY AREAS 213 



to be, until the crop gets too far advanced to admit of 

 cultivating it longer. The place for these crops has al- 

 ready been referred to (see p. 199). 



The legumes that may be grown are included in 

 some instances in the crops previously discussed. Al- 

 falfa, for instance, is included in the list of the hay 

 plants and peas in that of the small grains. To these 

 may be added field beans. It is at least questionable if 

 alfalfa will be grown to any great extent in spaced rows 

 and cultivated while growing in order to furnish hay, 

 and for the reason that it can be grown fairly well with- 

 out such cultivation. But it is more than probable that 

 it will be grown thus for seed. The extent to which the 

 seed industry may yet develop from seed grown on these 

 lines cannot safely be forecasted at the present time. 

 That the crop when grown for hay will be disced more or 

 less severely every year when sown on the bench lands, 

 is a foregone conclusion. The bean crop, which may be 

 safely grown in much of the dry area, must be given care- 

 ful cultivation wfyile it is being grown. 



Other crops that call for cultivation during the 

 growth period include roots and tubers, fruits and vege- 

 tables, windbreaks and trees. All the field roots grown 

 must be grown by the aid of cultivation, save in such 

 instances as when the seed may be scattered broadcast 

 on breaking. The same is true of potatoes and artichokes, 

 save when potatoes are grown on breaking, the tubers 

 being dropped beneath the proper sod furrow while the 

 land is being plowed. The aim should be, however, to 

 avoid growing them thus. The cultivation of fruit will 

 be necessary from year to year under dry land conditions. 

 Such cultivation will probably have to be kept up as long 

 as the shrubs and trees are to be kept in bearing. Of 

 course all vegetables will call for cultivation. The same 

 is true also of windbreaks and forest trees. The culti- 

 vation of these must be kept up until the leaves will 

 form a sufficient mulch to adequately protect them.
