﻿IRRIGATION AT UNIVERSITY FARM, DAVIS, CAL. 3 



During the growing season (ho growth and condition of the crops 

 were carefully observed, and at the end of the season the results were 

 as stated below : 



X<> irrigation. — At the end of November only about one-third ol- 

 die stand seemed to be alive, and this had made not more than a 

 1 or '2 inch growth after it was first cut in June.

One irrigation. — The alfalfa given one early irrigation showed 

 practically no growth after the first cutting on May 14. Even after 

 the heavy irrigation of June 5 it failed to make a substantial growth, 

 and at the end of the season not more than one-half of it was alive. 

 The explanation of this is that it was given too early an irrigation. 

 The plats were irrigated before the roots had penetrated beyond the 

 surface soil, and when this had dried out, following the first irriga- 

 tion, the roots were stranded in a surface soil without sufficient 

 moisture to forward the growth.
