Experimental Work in Dry-Farming 



567 



Since the continuously cropped plots had only been in cultivation 

 for two years, data obtained are not especially valuable. In Table 

 XXXIX the results of supplemental irrigation by flooding, summer 

 fallowing and continuous cropping are shown. The flooded land 

 received but one overflow, which was quite heavy, in the early 

 spring before crops were planted. 



Moisture conditions of land continuously cropped, summer fal- 

 lowed, and flooded are recorded in Table XL.
