The results of physical properties of agricultural products are often mentioned as a function of the change of their moisture content. If we try to compare the results of the works by other authors, we will notice accurate definition of the notion of material moisture content. A serious problem is right in the sphere of research on seeds. Experiments of some authors are executed with the biological moisture content; the time needed to execute the experiments is too short, the range of works are limited, it is not possible to repeat the experiments. A lot of authors employ samples with moisture content simulated in the laboratory; it is possible to prepare the material in storage, repeat the experiments and the metho- dology can be extensive. The aim of this work was to compare the results of selected physical properties of the seed chickpea (Cicer Arietinum L.) which were found with the biological moisture content (BMC) and simulated moisture content (SMC). The sizes of seeds, the mass of seeds, the coefficient of restitution during the impact of seeds on the plate (steel, wood, concrete). At the same time, quasi-statical charged seeds where compared and the values of force and deformation were read from the force - deformation curve in the bioyield point (BP). Results obtained at BMC and SMC differ noticeably.
