| Organic cropping of soya beans mainly depends on the successful control of weeds. Hoeing in between the crop rows can be effective but the mechanical control of weeds within the crop row is difficult. Objective of this study was to investigate the effect of three machines and two combinations thereof to control two model weeds seeded directly in the crop row of soya bean. Reduction of the soil cover (%) in the crop row was evaluated after the means were applied and compared to the control treatment (hoeing between the crop rows). Results of two experiments conducted in 2007 and 2008 show that soil cover of companion plants within the crop row can be reduced up to 70 % when compared to the control treatment. Before best treatments can be... |

| Oil flax was cropped in Switzerland in former times but seldom today. To investigate new varieties with respect to their agronomic performance and suitability for the production of cold-pressed oil, 15 varieties of spring flax were tested in the years 2005-2007 at one site. They were sown in small plots with four replicates and managed according the rules of Swiss organic farming. Averaged over the years, seed yield of the varieties ranged from 1.4 - 1.9 t/ha. Pressure of pests and diseases were generally low and weeds were controlled successfully by mechanical means. In order to recommend flax varieties for the production of oil, oil quality aspects need to be considered and investigated carefully. |
