GROWING GRAIN CROPS IN DRY AREAS 253 



rainfall is approximately 15 inches per year. When sown 

 alone to furnish hay, not less than 5 pecks should usually 

 be sown. 



Care of the crop. About the only care than can be 

 given to barley on non-irrigated lands after it has been 

 sown, is to harrow it as frequently as may be necessary 

 and at the time that may be opportune in each instance.

It may usually be harrowed with profit when the blades 

 begin to show, whether the ground is or it not crusted, 

 for many weeds will be thus destroyed just when they 

 begin to form roots. Subsequently the number of the har- 

 rowings must be determined by the character of the 

 weather and the severity of the same that may be present 

 in each instance. Usually from two to three harrowings 

 will suffice.
