s using the
BBCH-scale The BBCH-scale is used to identify the phenological development stages of plants. BBCH-scales have been developed for a range of crop species where similar growth stages of each plant are given the same code.

The phenological growth stages and BBCH-identification keys of faba beans are:
1 Stem elongation may occur earlier than stage 19; in this case continue with the principal stage 3
2 First internode extends from the scale leaf node to the first true leaf node
