Question
the advance equation for a border is
(t=0.8x) where (t) in minutes and (x) in
meters; the recession equation is
(t=Ta+0.2x), Ta is the application time, and

mm and t in minutes. If the application
time is 180 minutes, the length of the
water run is 300 m, and the irrigation
adequacy is 85%, then the NDI is
approximated to:
A. 150 mm
В.
50 mm
С.
None of these options
D. 200 mm
