Yam bean (Pachyrhizus erosus (L.) Urban) is an underutilised tuberous legume crop
which has great potential as a food crop. As a root crop, it produces high yields and
as a legume, it can produce protein-rich food. The phenological growth stages of yam
bean are first described here using BBCH (Biologische Bundesanstalt,
Bundessortenamnt and Chemische Industrie) scale. We have developed a basic and
extended numerical BBCH scale for the identification of different phenological
growth stages of yam bean. All phenological stages, including germination (stage 0),
leaf development (stage 1), formation of side shoots (stage 2), stem elongation (stage
3), tuber formation (stage 4), inflorescence emergence (stage 5), flowering (stage 6),
development of pods (stage 7), ripening of pods (stage 8) and senescence (stage 9)
are described using the BBCH scale. This BBCH phenological study in yam bean will
be helpful for better crop management, crop improvement and characterisation of
germplasm. This scale will also be useful for the yield enhancement of this crop as an
emerging underutilised tuber crop.
