Dear all,
Two values are calculated which are averages of soil water deficit
factors 1 and 2 during each growth stage in soil water balance models of
the crop models under DSSAT shell. If the aim of a certain farmer is to
maximize yield, what shoud the value of these factors be to attain
his/her goal? Is it wise to manage irrigation amount and timing such
that potential uptake divided by potential transpiration is not below
one in each growth stage to attain his/her goal? Can someone explain?
Thanks for your time.
