Abstract

A one year experiment was conducted to evaluate the influence of undersowing in vegetable fields. The field experiment was established in 2011 at the Hessian State Frankenhausen research farm of the University of Kassel. In this experiment, randomized block design (RBD) was applied. Undersown (US) white clover (Trifolium repens L.) was established either immediately after planting of organic leek (Allium porrum L.) or 48 days after transplanting of leek. As second factor, the comparison between mulched and non-mulched system was included. The yield was influenced by mulching of clover. Treatments with mulch showed higher yield (13.6 and 19 t ha-1 ) at the first and second harvests, respectively. Treatment with late undersown (LS) and with mulch produced higher yield (14.3 and 21.3 t ha-1 ) at the first and second harvests, respectively; and at both harvesting time. The experiment shows that treatment with LS and without mulch produced higher dry matter (DM) percentage at the second harvest. DM content was significantly lower at treatment with mulching at the second harvest. The nitrogen (N) uptake for treatment with late undersown (LS) and mulching was significantly higher than other treatments at the second harvest. There is no significant difference for potassium (K) uptake at the second harvest.
