Mechanische Unkrautregulierung in der Saatreihe von Soja

Summary in the original language of the document

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 recommended for the farmers,
large-scale tests have to be conducted in order to improve the use of these means to
keep the impact on the main crop as low as possible.
