| Experiments were conducted to determine how tillage intensity, the use of biofumigation brassica cover crops and mixed cropping with oats affect the performance of organic peas with respect to weed pressure, diseases, and yield. Fields were either ploughed to a depth of about 15-20 cm or only to about 8 cm in late summer followed by either Sinapis alba (low glucosinolate (GSC) content), Raphanus sativus (medium GSC) or Brassica juncea (high GSC). Brassicas were mulched in fall right before flowering and incorporated in the top soil. In mixtures with oats seed rate for peas was as in pure stands, for oats it was 20 %. There was a dramatic spring drought in 2011 resulting in severe water stress for the peas in 2011. Weeds were significantly reduced by about... |

| A total of 39 organic faba bean and 59 pea seed lots obtained during 2009-2011 from 32 organic farms throughout Germany were assessed for seed-borne fungi. Seed samples collected from the harvested fields grown from these seed lots were also assessed. The focus in the pathogen identification was on the ascochyta blight complex pathogens Ascochyta pisi, Mycosphaerella pinodes and Phoma medicaginis in pea and A. fabae and P. medicaginis in faba bean and on Fusarium spp. Fusarium spp. were found only rarely on peas with 40 of the seed samples and 44 of the harvested samples free of Fusarium spp. and the maximum infestation rate of 12 % in one harvested sample. Eighteen of the sown and 40 of the harvested lots had infestation rates of > 10 % with the... |
