Recommendations 

 On the basis of the collection and analysis of the 

 data on vegetative v;ater use^ as presented in this report^ and 

 on the conclusions drav;n therefrom, it is recommended that: 



1. The evapotranspiration studies at the present 

 sites be continued until sufficient data can be collected to 

 provide reasonable estimates of evapotranspiration under the 

 range of climatic conditions vjhich can occur at these locations. 



2. Additional sites for evapotranspiration measure- 

 ments be established in locations having different climatic 

 conditions than those now being measured to determine variability 

 of evapotranspiration coefficients ( i.e.. Delta area, coastal 

 area^ and desert areas). 



3. The scope of the present program be expanded to 

 include measurements of applied water under different irrigation 

 practices and lengths of grov.'ing seasons for major crops within 

 the various agricultural zones of the State. This would provide 

 the basic information needed to determine irrigation efficiencies, 

 drainage requirements, and, with the unit evapotranspiration 

 values, to determine total irrigation water requirements.
