| Die Zielsetzung des Forschungsprojektes war es, verschiedene Mischfruchtanbausysteme von Getreide oder Leguminosen mit Ölsaaten zu untersuchen. Es wurden zweijährige Parzellenversuche mit ökologischer Bewirtschaftung an vier Standorten in Deutschland durchgeführt. Bei den Sommersaaten wurden Gemenge aus halbblattlosen Erbsen (Pisum sativum L.) mit Leindotter (Camelina sativa L. Crantz), weißem Senf (Sinapis alba L.) oder Sommerraps (Brassica napus L.), Gemenge aus schmalblättriger (blauer) Lupine (Lupinus angustifolius L.) mit Leindotter oder Saflor (Carthamus tinctorius L.), Gemenge aus Sommerweizen (Triticum aestivum L.) mit Öllein (Linum ustitatissivum L.) oder Leindotter sowie Gemenge aus Öllein mit Leindotter untersucht. Bei den Winterungen wurden... |

| Mixed cropping systems with oil crops are of growing interest in organic farming. They can offer agricultural advances like competition against weeds, support against lodg¬ing and buffering of yield fluctuations. The aim of the cultivation method is to gain additional oil yields for energy or feed purposes. The reported higher land-efficiency-ratios of those mixed cropping systems should lead to higher nutrient requirements. But it is unknown if the different crops just compete for rare soil nutrients or if comple¬mentary effects in mixed cropping systems lead to higher nutrient efficiency. In a field study N-contents in plants and N uptake of diverse mixed cropping systems were compared to sole cropping systems. In linseed (Linum usitatissivum) or false... |

| Oil crops can be integrated in organic crop rotations in mixed cropping with other crops. The cropping system achieves only low oilseed yields but increases productivity per area in total yield. In theory soil nutrients in mixed cropping systems can be used more efficiently due to different root architecture and growing times of the plants. But even the nutrient demand should increase with higher productivity. In the study nutri¬ent content and uptake of seeds and straw of mixtures of winter rape with winter-barley, peas, or rye, of spring peas with spring rape, mustard or false flax, of blue lupine with safflower or false flax, of spring wheat with linseed or false flax and of linseed with false flax were screened. Productivity per area was increased in... |
