BBCH SCALE PDF

In biology, the BBCH-scale for other brassica vegetables describes the phenological development of vegetables such as brussels sprouts , cauliflower and broccoli using the BBCH-scale. From Wikipedia, the free encyclopedia. The phenological growth stages and BBCH-identification keys of other brassica vegetables are: Growth stage Code Description 0: Germination 00 Dry seed 01 Beginning of seed imbibition 03 Seed imbibition complete 05 Radicle emerged from seed 07 Hypocotyl with cotyledons breaking through seed coat 09 Emergence: cotyledons break through soil surface 1: Leaf development Main shoot 10 Cotyledons completely unfolded; growing point or true leaf initial visible 11 First true leaf unfolded 12 2nd true leaf unfolded 13 3rd true leaf unfolded 1.

The BBCH-scale is used to identify the phenological development stages of plants [1]. BBCH-scales have been developed for a range of crop species where similar growth stages of each plant are given the same code.

Phenological development stages of plants are used in a number of scientific disciplines crop physiology , phytopathology , entomology and plant breeding and in the agriculture industry risk assessment of pesticides , timing of pesticide application, fertilization, agricultural insurance. The BBCH-scale uses a decimal code system, which is divided into principal and secondary growth stages, and is based on the cereal code system Zadoks scale developed by Zadoks [2].

Allegedly, the abbreviation is said to unofficially represent the four companies that initially sponsored its development; Bayer , BASF , Ciba-Geigy , and Hoechst. From Wikipedia, the free encyclopedia. The BBCH-scale uses a decimal code system, which is divided into principal and secondary growth stages, and is based on the cereal code system Zadoks scale developed by Zadoks [2] The abbreviation BBCH derives from the names of the originally participating stakeholders: " B iologische B undesanstalt, Bundessortenamt und CH emische Industrie".

BBCH-scale

Cereal growth staging scales attempt to objectively measure the growth of cereals. The Feekes scale is a system to identify the growth and development of cereal crops introduced by the Dutch agronomists Willem Feekes in The Zadoks scale is a cereal development scale proposed by the Dutch phytopathologist Jan C. Zadoks that is widely used in cereal research and agriculture. Knowing the stages of development of a crop is critical in many management decisions that growers make. They are represented on a scale from 10 to
