Original Article Study of the Influence of the Roller Work on the Seedbed Preparation for Seed Production of Perennial Leguminous

There were taken in study a total of 4 species of perennial leguminous pastures namely: red clover Select 2 variety, alfalfa Satelit variety, sainfoin Vlamar variety and trefoil Dacia 1 variety. For these species we made studies on how the seedbed preparation for sowing using annular or flat roller and the influence of this work on the production of seed lots. To prepare the seedbed for establishing perennial leguminous seed lots using the ring roller before sowing and the flat roller after sowing favors a better rising for clover, alfalfa, sainfoin and for trefoil the optimum variant is when using the annular roller before and after sowing. In the first year of vegetation the using of the ring roller before seeding to alfalfa and trefoil favors the obtaining of significant increases of dry matter, while the biggest increases of sainfoin dry matter is obtained by using the ring roller before and after sowing. In the second year of vegetation using the roller for perennial leguminous, the seedbeed lots are influenced differently for the dry production of the first scythe. Therefor, at trefoil and red clover the maximum quantity of dry matter was obtained when using the ring roller before sowing and the plain one after sowing, while for sainfoin and alfalfa the maximum production was obtained in the case of using the ring roller both before and after sowing. The use of roller at seedbed preparation for the perennial leguminous brings significant increases of seed production. The best option for preparing a good seedbed perennial leguminous seed is when using the ring roller both before and after sowing for trefoil and the plain roller for alfalfa and red clover, respectively before and after sowing for sainfoin
