The daily ETC rate is multiplied b the <br /> irrigation or qu Y y p Y <br /> g <br /> number of days since the last irrigation to obtain the net irrigation <br /> l requirement. Based on figure 6 in Docrenhos and Pruitt (1977) . An irriga- <br /> tion or rainfall of 2 , 4 , 6 , etc. indicates that irrigations or rainfall <br /> ' occur on every second, fourth, sixth, etc . , day. <br /> 17 <br /> k <br /> J <br />
