YIELD AND COST OF PRODUCTION

Pacific northwest. This is perhaps partly due to the ideal 

 weather prevailing there. A long, wet winter with little frost; 

 a cool, wet spring, gradually fading away into the warmer sum- 

 mer; only light rains after blossoming; abundant sunshine and 

 rather dry air toward harvest; and dry weather for harvest 

 seem to be the most favorable weather conditions for the 

 maximum yield. Sixty to 70 bushels per acre were harvested, 

 even in the sixties. A volunteer crop may give 25 to 30 bushels.
