Seeds of agricultural crops experience mechanical effects of varying degrees when interacting with the working bodies of agricultural machinery. It is known that seed germination directly affects crop yields. In this regard, the study of the effect of the mechanical action of external forces acting on seeds on germination is relevant. In the conditions of Primorsky krai, one of the most widespread and important agricultural crops for the agro-industrial complex of the region is soybeans. The article presents some results of theoretical and experimental studies to assess the effect of mechanical loading with external concentrated load before sowing on soybean seed germination. Theoretically, the distribution of stress in a soybean seed under the action of a concentrated compressive load on it is considered in order to justify its distribution over the volume of the seed, which causes the activation of seed germination and determines the nature of their destruction. Experimental dependences have been obtained showing the change in seed germination of three soybean varieties zoned for Primorsky krai depending on the concentrated compressive load acting on them.
