The paper presents the testing results during seed processing of natural seed of red clover and alfalfa, with different initial purity. Because of their exceptional importance in the production of animal feed in the Republic of Serbia, a large number of perennial leguminous plants are grown. The most important leguminous fodders in Serbia are alfalfa and red clover. This is because of the areas they occupy, as well as the nutritional quality for domestic animals. The seed used for the crop establishment of these plants must be clean, with high germination and genetic value. Many of these requirements could be accomplished by seed processing and removing all impurities and seeds of poorer quality. The aim of this study was to show the parameters of efficiency of processing machines of these two perennial legumes seed. The basic indicators of the parameters of efficiency of seed processing are the quality and quantity of the obtained seed. All relevant parameters which define the characteristics of seed processing machines are presented: pure seed (%), weed and other seed crops (%), inert matter (%), amount of processed seed (kg), seed losses (%) and processing output (%). The obtained results enable the selection of suitable equipment and their proper adjustment for seed processing, depending on the quantity and type of weeds and other ingredients presented in the natural seed. |
