    Mechanical in-row weed control in transplanted and direct-sown bulb onions2008In: Biological Agriculture & Horticulture, ISSN 0144-8765, E-ISSN 2165-0616, Vol. 25, no 3, p. 235-251Article in journal (Refereed)
    Abstract [en]

    Different strategies for mechanical in-row weed control were evaluated in direct-sown and transplanted bulb onions (Allium cepa) in terms of in-row weeds, labour requirements for hand weeding and marketable yield. Transplanted onions generally performed much better than direct sown onions. The best strategies in transplanted onions decreased the hand weeding time by 70% and increased marketable yield by 96% compared with the best strategies in direct-sown onions. In transplanted onions, one weed harrowing and three in-row cultivations with torsion weeders reduced in-row weed numbers by 85%, reduced hand weeding time by 73%, and caused no yield reduction compared with the normal strategy of one weed harrowing and ordinary inter-row cultivation. In direct-sown onions, pre-emergence flame weeding and repeated torsion weeding reduced hand weeding time by 40% and caused no yield reduction compared with flame weeding and inter-row cultivation. The effectiveness of in-row cultivation was very dependent on the timing of treatments. Using transplanted onions and in-row weed control is a way to ensure high yields and reduce labour requirements for hand weeding compared with direct-sown onions and interrow cultivation. © 2008 A B Academic Publishers.

    Developing soy production in central and Northern Europe2017In: Legumes in Cropping Systems, CABI International , 2017, p. 109-124Chapter in book (Other academic)
    Abstract [en]

    The soybean is an important ingredient of livestock feed in Europe and is also widely used in foods. Most soy used in Europe is imported (about 97% as beans and meal), mainly from South America and the USA. European soy production is currently concentrated in the south (Italy) and south-east (Balkan countries). Based on research conducted in Sweden and Germany, this chapter provides pointers to the development of the soy crop in central and northern Europe. It provides an overview of the history of the development of the crop in northern Europe, outlines relevant recent field research, and discusses aspects of good production practice. We focus on new production areas, generally north of traditional production areas. In recent years, interest in growing soybeans has spread east and north from Romania and Italy and parts of France to Austria, Germany, Hungary, Slovakia, the Czech Republic, Poland and even the BeNeLux countries, the Baltic and Scandinavian countries, with subsequently rising acreages. In order to succeed with soybean cropping in central and northern Europe, cultivars of the 00, 000 or 0000 maturity groups should be used. Grain yield in Scandinavia is about 2 t/ha. Crops in Germany and Austria produce about 2.5-3.5 t/ha. Knowledge about locally adapted cultivars and production technology is needed to support the development of the crop in new production regions. To ensure profitability of this new cropping, infrastructure for processing to feed and food has also to be developed. © CAB International 2017.

    Innovation in mechanical weed control in crop rows2008In: Weed research (Print), ISSN 0043-1737, E-ISSN 1365-3180, Vol. 48, no 3, p. 215-224Article in journal (Refereed)
    Abstract [en]

    Weed control within crop rows is one of the main problems in organic farming. For centuries, different weed removal tools have been used to reduce weeds in the crop rows. Stimulated by the demand from organic farmers, research in several European countries over the last decade has focused on mechanisation using harrowing, torsion finger weeding and weeding with compressed air (Pneumat). Intelligent weeders are now being developed which offer more advanced ways to control weeds, including larger ones and to leave the crop plants unharmed. One of the first commercially available intelligent weeders, the Sarl Radis from France, has a simple crop detection system based on light interception, which guides a hoe in and out of the crop row, around the crop plants. The inclusion of innovative technologies, including advanced sensing and robotics, in combination with new cropping systems, might lead to a breakthrough in physical weed control in row crops leading to significant reductions, or even elimination, of the need for hand weeding. © 2008 The Authors.
