The results of studies of the physical properties of agricultural seeds over the past 100 years are summarized. Three periods of research have been identified: the first - the beginning of the 20th century before the Second World War; the second - from the Second World War to the 1990s; third - early 2000s to present. The relation is shown between conducting research on the physical properties of seeds and developing technologies for post-harvest processing and seed preparation. It is shown that the physical properties of seeds represent the starting points and are fundamental in the design of machines and technological processes for sowing, harvesting, post-harvest processing and pre-sowing preparation of seeds. The physical properties of seeds that can be used in seed separators have been determined: dimensional characteristics, shape, density, surface condition, ability to float to the surface of a liquid or fluidized layer, color, elasticity, electrical conductivity, chlorophyll fluorescence. The size characteristics of agricultural seeds are generalized. crops, as well as weed seeds. The features of seed separation by thickness, width and length are described. It is shown that in the process of separation according to different characteristics, the shape of the grains has a significant influence on the process. It has been established that further development of seed preparation technologies based on existing knowledge about the physical properties of seeds is ineffective. To develop technologies for the preparation of new generation seeds, it is necessary to conduct systematic research using seed materials in various soil and climatic zones of countries.
