Switchgrass seeds rising increase

The article presents the results of research on improving the efficiency of switchgrass seed germination and rising in its sorting by specific weight. It has been proved that in the main sorting, under appropriate pneumatic sorting tables mode, seed germination and rising rates which made 77-78 % increased by 10 %. Re-sorting the seeds, which fell to the medium fraction and waste ensured obtaining prepared seed with germination and rising energy equal to that of the main sorting – 87 %. Prepared seed yield with 87 % rising increased from 53.9 to 78.6 %. Optimal operation of pneumatic sorting tables for both basic and re-sorting has been found out during the studies.

Key words: germination, mode of sorting, switchgrass, seed.
