SOME RESULTS OF THE EXPERIMENT ON SCARIFICATION OF SEEDS OF FORAGE LEGUME (THE SAMPLE OF ALFALFA SEEDS)

If the hard seed (seed that is viable but has an impervious coat) content of legumes greater than 20%, scarification should be considered. Scarification nicking coat to allow moisture penetrate [1]. This type treatment before sowing great importance, as it increases yield fodder plants by reducing rate rare and expensive seeds, cost sowing, accelerating germination, increasing percentage germination. article reflects results a planned experiment determine effectiveness device for impacting alfalfa depending on factors such impact speed, angle, surface grit, presented mathematical model relationship between these determined their optimal values.
