Summary

We compared field emergence and yield of a white- and a coloured-flowered variety of faba bean (Vicia faba) in relation to Bruchus rufimanus seed damage in a factorial, hand sown mini-plot field experiment. Further manipulating factors at sowing were, foot root rot inoculation with a 4-species Fusarium-mixture, a seed dressing with powdered testa material of the coloured-flower variety and sowing depth. In both varieties Fusarium-inoculation was the most detrimental and significant factor to field emergence and yield, interacting with a concordant B. rufimanus effect. Expectedly, the white-flowered variety was most affected. Tannin-containing testa meal did not reduce or compensate the impact of fungal inoculation and/or B. rufimanus. We hypothesize that B. rufimanus testa damage affects seedling vigour via reported faster water imbibition, causing cellular rupture and higher solute leakage which may enhance soilborne foot root rot incidence and finally yield. The results are discussed in the context of future research objectives.
