Seed damage has a negative impact on the subsequent development of the plant, its yield, and generally on the economic efficiency of grain production. Main percentage of the grains injury occurs in the post-harvest processes, particularly in the grain cleaning. One way of solving this aim is reducing of macro and micro damage of seeds by using of the new polymeric materials. Researches have been conducted to reduce the micro and macro of injury barley seeds (feed material) through the use of new sieves made of polymeric materials UHMW PE for agricultural machinery.
