Erfassung pflanzenbaulicher Parameter im ökologischen Anbau der morphinarmen Wintermohnsorte „Zeno Morphex“

Experience in the biological cultivation of poppy in Germany, especially when sown in autumn, is small. That is why research is needed concerning yield stability, weed management and nutrition and is the reason for this study that deals with different seeding dates and varying nitrogen nutrition and their effects on plant development and yield. The chosen fertilizer was horn meal in small (0-1 mm) and coarse grained (4-7 mm) particle sizes. Both were applied either with 30 kg N ha-1 or 80 kg ha-1 . Plant height of the first seeding date (S1) was highest for the variety that received 80 kg N ha-1 small grained horn meal (Final heigt on 22.06.18: 123,2 cm, p
