Abstract

This study evaluated the effect of seed weight and seed treatment on yield and growth parameters in a three-year field trial. Seed weight treatments were tested in three levels of thousand seed weight (TSW): low 4.28 g, medium 5.00 g and high 5.69 g, with and without a biostimulant seed treatment of Lumibio Kelta. Although statistically significant differences were not found in all experimental years, the three-year results showed that sowing seeds with higher seed weight increased the initial and final stand counts, root length, seed yield and oil content. The final stand at harvest time averaged over the three years ranged from 23.0 (low TSW) to 29.5 plants per 1 m2 (high TSW). Plants from high TSW seed had an average of 1.1 cm longer roots than plants from low TSW seed. The average yield increased with TSW: 5.49 t/ha (low TSW), 5.86 t/ha (medium TSW), and 5.94 t/ha (high TSW). High TSW also yielded higher oil content (45.77%) compared to the medium (45.25%) and low TSW (45.27%). No statistical difference could be detected in the initial emergence counts or final seed quality according to seed treatment. Seed treatment with the biostimulant increased root length and seed yield. Plants from seeds treated with the biostimulant had roots with an average of 0.6 cm longer, yielding 0.2 t/ha higher than the non-treated ones.
