Influence of seeding density on winter rape seed and oil yields in conditions of SCDA lovrin

Absztrakt

Rapeseed seeding density plays an important role in achieving seed and oil production. To quantify this role
there have been initiated researches in S.C.D.A. Lovrin, Timis county in bifactorial experience: varieties and
densities.
Best results are obtained in the range of 100-150 germinable seeds/m² density.
The oil content is strongly influenced by seeding density, having different influences for each hybrid. In
Pamela variety and PR46W14hybrid, the oil content in seeds is reduced with increasing seeding density from
50 germinable seeds/m² to 200 germinable seeds/m². In Extend and Exotic hybrid, oil content increases with
density (the highest values were obtained at the density of 200 germinable seeds/m²).
Average productions obtained this experimental year ranged between 3034 kg / ha and 3460 kg / ha.
Both seed production and seed oil content are important elements for oil production.
