Aims

To evaluate the effects of different seeding systems, which alter seed bed utilization on vetch biomass production.

Key messages

Narrow disc seeding system resulted 72% and 87% more biomass than wide row knifepoint and paired row systems across all varieties. Timok yielded 1.5 t/ha of biomass when averaged across all harvesting dates, which was 13% and 25% higher than Studenica and Morava.

Establishment and plant growth: The different seeding systems had a large effect on plant establishment with greater number of plants emerging in the disc sown treatments. As the trial was dry sown, the discs were not able to penetrate as deep as the tine-based systems (Root Boot and PSS) and therefore it is possible that the shallower sowing has resulted in an establishment advantage. However, the seed bed was noticeably more cloddy following seeding with the tine-based systems, which may also have had a negative effect on the establishment, as seed-soil contact was likely to be poorer.

Biomass: The disc seeding system resulted in 99 – 166% more biomass than the tine systems at each harvest date. By the final September harvest data, the narrow row disc system with the highest SBU resulted in over 1 t/ha (117 – 166%) more biomass than the other seeding systems.
