Abstract

The potential new oil crop Lepidium campestre (field cress) was undersown with long and short row distances in spring barley in three-year trials with eight replications. Plots with no undersowing were used as controls. The purpose was to assess the effect on barley-grain yield of the oil crop and its seed-yield potential. In the plots without undersowing, with long and short row distance of undersown L. campestre the barley-grain yields in the three years were, on average, 5069, 5130, and 5330 kg/ha, respectively. The trials showed a statistically significant positive effect on barley yield of undersowing with short row distance. The average seed yields of L. campestre in the following years were 4697 and 5000 kg/ha for plots with long and short row distance, respectively. The results are positive in relation to possibilities to domesticate this species as a new undersown oil crop for an energy-saving and environmentally friendly cropping system.
