Germination capacity of loaded seeds was controlled and safe load limit for pea seed was found. Two varieties of pea seed for investigation were used. The range of stress level 1-20 MPa were applied and compression was repeated up to 50 times. In order to set seed for germination test were used the cassette design by author. Germination capacity decreases with the increase of compression and the force caused decrease of germination capacity was 5 times higher than elasticity limit.
