To examine Rhizobia response in faba beans
Rhizobia type or rate had no effect on yields. However a small adjoining trial showed a trend to increased yield due to rhizobia inoculation when plants were stressed by waterlogging. This is in keeping with results from last year's trial where large differences between inoculated and uninoculated treatments were attributed to waterlogging stress in winter and spring. This year's trial was sown on raised beds. The absence of waterlogging stress and the release of nitrogen from stubble from the previous poppy crop may account for the lack of yield response to inoculation. Yields were high this year, with some adjoining irrigated plots reaching 7 t/ha.
