Cereal growth staging scales Cereal growth staging scales Cereal growth staging scales attempt to objectively measure the growth of cereals. In agronomy, the "BBCH-scale for cereals"' describes the phenological development of cereals using the BBCH-scale. The phenological growth stages and BBCH-identification keys of cereals are: with stages 21 The Feekes scale is a system to identify the growth and development of cereal crops introduced by the Dutch agronomists Willem Feekes (1907-1979) in 1941. This scale is more widely used in the United States than other similar and more descriptive scales such as the Zadoks scale or the BBCH scale. Like other scales of crop
