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. [ 1 ] [ 2 ] This scale is more widely used in the United States [ 3 ] than other similar and more descriptive [ 4 ] [ 5 ] scales such as the Zadoks scale or the BBCH scale .
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 Jan Zadoks. [2] The abbreviation BBCH derives from the names of the originally participating stakeholders: "Biologische Bundesanstalt, Bundessortenamt und CHemische Industrie".

The use of dwarfing genes, known as Rht genes, which have been incorporated from both Triticum and Secale, has resulted in a decrease of up to 20 centimetres (7.9 in) in plant height without causing any adverse effects. [citation needed] A 2013 study found that hybrids have better yield stability under yield stress than do inbred lines. [26] [27]

Growth charts can also be used to predict the expected adult height and weight of a child because, in general, children maintain a fairly constant growth curve. When a child deviates from his or her previously established growth curve, investigation into the cause is generally warranted.
Oryza sativa, having the common name Asian cultivated rice, [2] is the much more common of the two rice species cultivated as a cereal, the other species being O. glaberrima, African rice. It was first domesticated in the Yangtze River basin in China 13,500 to 8,200 years ago. [3] [4] [5] [6]
Agronomic studies often focus on the above-ground part of plant biomass, and consider crop growth rates rather than individual plant growth rates. Nonetheless there is a strong corollary between the two approaches. More specifically, the ULR as discussed above shows up in crop growth analysis as well, as: = . = .
