Efficiency of alfalfa seed processing with different seed purity

The work was carried out analysis of the impact of the initial purity of raw alfalfa seed on the resulting amount of processed seed in the processing. Alfalfa is very important perennial forage legume which is used for fodder and seed production. Alfalfa seed is possible to achieve high yields and very good financial effects. To obtain the seed material with good characteristics complex machines for cleaning and sorting seeds are used. In the processing center of the Institute for forage crops in Kruševac, alfalfa seed with different initial purity are processed. It is very important that the difference between the amounts of pure seed from laboratory assessment and the actual amount after processing, are low. The six parties of natural seeds of different purity in the range of 74 % to 77.1 % were processed. Also, after each stage of treatment, losses of seeds were measured and seed rate obtained at the end of the processing.
