s lower limit (if exists), are assigned to class N. Given this ordering of crop’s parameter interval limits, the appropriate MF is the right triangular MF (Fig. b). This follows from the fact that the <em>most-suitable</em> (or <em>highly-suitable</em>) class S1 has interval limits less than the limits of other suitability classes. By doing so, the crop’s parameter interval limits are arranged in ascending order in the <span class="math inline">\(x\)</span>-axis on points <span class="math inline">\(v_1
