Summary

Winter peas (Pisum sativum L.) are a promising alternative to spring peas in organic farming. Intercroppingwinter peas and cereals may be a beneficial way to improve lodging resistance in normal-leafed andweed suppression in semi-leafless winter peas. At the same time, there is an increasing interest in areduction in tillage intensity, e.g. shallow ploughing. A normal-leafed, coloured-flowered (cv. E.F.B. 33)and a semi-leafless, white-flowered winter pea (cv. James) were cultivated as sole crops or in intercropswith triticale (Triticosecale Wittmarck) on a loam soil under Northern German conditions during twoseasons (2009/2010, 2010/2011) and compared for winter survival, lodging resistance, yield performance,grain quality and succeeding winter wheat yield. The two ploughing depths were short-term shallowploughing to 10–12 cm and continuous deep ploughing to 25–27 cm. Intercropping did not improvewinter survival, which depended on pre-winter development. Owing to the low lodging resistance ofnormal-leafed winter pea E.F.B. 33, sole cropping is not advisable. Intercropping normal-leafed winterpea E.F.B. 33 and triticale resulted in a better yield performance (2.54–3.39 t d.m. ha−1) than the semi-leafless winter pea James sole (0.97–1.79 t d.m. ha−1) or intercrops (2.05–2.86 t d.m. ha−1). E.F.B. 33 hadsignificantly higher grain crude protein, crude fibre and macronutrient contents, whereas the crude fat,starch and sugar content as well as the energetic feed value were higher in James. Wheat yields afterE.F.B. 33 sole and intercrops were higher than after the corresponding James sole or intercrops. Thebiomass production, yield performance and the energetic feed value of winter pea sole and intercropswere comparable between ploughing depths or higher after shallow ploughing. Thus, E.F.B. 33-triticaleintercrops provided better results than James sole or intercrops, except for the energetic feed value, andshallow ploughing was a good alternative to deep ploughing for the cultivation of winter peas.
