Comparative cha­racteristics of growth and development scales of the pea (Pisum sativum L.)




pea growth and development, uniform exten­ded scale – ВВСН, Kuperman scale


Purpose. Compare growth and plant development scales: the unified extended BBCH scale and Kuperman scale for peas.

Results. Pea cultivation technologies are based on the accurate application of agrotechnical operations for crop care: protection from weeds, pests, diseases, and foliar nutrition. Actually, in Ukraine the adaptation of elements of cultivation technology is based on Kuperman scale, which makes it difficult to harmonize with international experience in the field of pea cultivation. Comparison of the unified extended BBCH scale and Kuperman scale for pea planting does not exist, which forces researchers or agronomists to use one of these scales in their work, in fact, ignoring the developments of the cultivation techno­logy based on another scale. Based on the generalization of the well-known pea growth and development scales – ВВСН and Kuperman – comparative tables and correspondences between the physical and biological time of plant development were worked out. The obtained information is important when developing efficient pea production maps, since the correct application of theoretical knowledge in practice enables the appropriate agrotechnical methods to be applied in a timely and effective manner. In scales, standar­dized numerical designations are used for a phase or stage of growth and development that have the same meaning, regardless of year, region, or pea variety. Digital signs have advantages over descriptive when information is entered into a computer.

Conclusions. In the domestic practice it is customary to use a scale developed by F. M. Kuperman, while the unified expanded scale of ВВСН is widespread not only in Europe but also throughout the world. However, the definition of organogenesis stages is too complicated in practice and, besides the corresponding skills, requires the use of scientific equipment. But the unified extended ВВСН scale, despite some complexity from the producer’s point of view, is best suited for the creation of pea cultivation digital technology. The data of the comparison of growth and development scales: the unified expanded BBCH scale and Kuperman scale allow using recommendations on pea cultivation technology in agronomic practice, regardless of the scale they were worked out.
