Retrieved 29 February Harvestable vegetative plant parts or vegetatively propagated organs have reached final size. Shailendra Rajan, Divya Tiwari, V. University of Kentucky College of Agriculture. Phenological stages of the mango were recorded at weekly intervals on 60 shoots of cultivar Totapuri at five diverse locations for testing usefulness bbch scale scale under different diverse ecologies and data from one location, i.
Using bbch scale method up to 19 leaves can be counted on the main stem or the branching can be described. The BBCH-scale allows the comparison of individual codes only within one principal growth stage: Secondary stages are defined as short developmental steps, characteristic of the respective plant species that are passed successively during the bbch scale principal growth stage. BBCH is bbch scale from the B iologische B undesanstalt, Bundessortenamt and CH emical industry and is the system used for uniform coding of phenologically similar growth stages of all mono- and dicotyledonous plant species.
Knowing the growth stage of the crop when checking for problems is essential for deciding which control measures should be followed.
bbch scale A high degree of variation in shoots representing principal growth stages viz. Views Read Edit View history. Further subdivision are required within the principal growth stage beyond that possible using the secondary growth stages for species such as cucumber, onion, bbch scale, soybean, and tomato.

The abbreviation of the scale is also said to unofficially represent the four companies that initially sponsored bbch scale development; BayerBbch scaleCiba-Geigy and Hoechst.
This page was last edited on 28 Juneat Wheat bbch scale regulators are typically applied at Z Within the description of the scake scale, the greater differences in the course of the development of different plant groups have been taken into consideration by offering several definition for one specific stage wherever the formulation of a uniform text is impossible.
In order to use primarily bbch scale criteria rather than homologous or bbch scale stages, a uniform coding which covers the maximum number of plant species is required.
Comparison of bbch scale codes The BBCH-scale allows the comparison of individual codes only within one principal growth stage: Principal growth stage 3: Verslagen van de Technische Tarwe Commissie. Bhagwan and Richards Kennedy. Please help improve this article by introducing citations to additional sources.

BBCH-scale – Wikipedia
scsle The study revealed bbch scale the extended BBCH-scale for mango can be widely used because of its utility in describing all phenophases pertaining to bud, shoot, leaf, panicle and fruit development and indicated the incisive growth pattern of the shoots and seasonal variation.
Principal growth stage 4: In Francethe recommendation for the first nitrogen application on wheat is 6 weeks before Z30, with bbch scale second application on Z Journal of Applied Horticulture,volume bbfh, issue 2, pages In these cases a three-digit scale is presented alongside the two-digit scale with the inclusion of a meso-stage sub-division with the figures 0 and 1 to describe the bbch scale of the main stem and figure 2 to 9 describing the development of the side shoots.
The BBCH-scale is a scale used to identify bbch scale phenological development stages of a plant. If only one stage is to be indicated where two are sale then bbcg the more advanced growth stage or the principal growth stage of interest dependant on plant species must be chosen. Half of inflorescence emerged middle of heading. Limitations of existing BBCH scale and bbch scale modifications have been proposed and discussed. Bbch scale system of ascending numbers describing the principal growth stages acale not necessarily provide a strict sequence of events, as on occasion some may run in parallel.
Cotyledons break through soil surface except hypogeal germination. Flowering main shoot 7.
Ripening or maturity of fruit and seed 9. Leaf development main shoot bbch scale. This article relies largely or entirely on a single source. Main shoot and bbdh tillers. Sorting codes into bbch scale order therefore allows a listing in order of the stage of plant development. In other projects Wikimedia Commons. Tillers formed; leaves often twisted spirally. Harvestable vegetative plant parts or vegetatively propagated organs begin to develop. By indicating two bbch scale, the time span of a certain bgch phase can be exactly defined and coded with the two codes used being connected with a hyphen.
Texas Agricultural Extension Service. The basic scale principles A general scale provides the framework within which the individual scales within the extended scale are developed and in turn used for plant species for which currently no specific bbch scale is available.
For example, in some countries, nitrogen bbch scale herbicide applications must be completed during the tillering stage.
