Abstract

The periurban area of San Genaro (Santa Fe, Argentina) is affected the Ordinance 18/2008 that prohibits the use of agrochemicals. Farmers within this area, mainly milking family dairy farms, are interested and in need of alternative management strategies of their oat forage with Bermudagrass (Cynodon dactylon).. Therefore, local institutions called for the assemblage of working teams to research on-farm productive alternatives. This led to a participatory action research (PAR) process to provide agroecological Bermudagrass management strategias for periurban areas. Therefore, a consociation of oat with different species was sowed together with one of the farmers, in order to evaluate intercropping soil covers and find out a combination of species with the capacity of managing Bermudagrass. The first year, oats forage was intercropped with Vicia villosa, Lollium multiflorum, Trifolium repens and Trifolium pratense while at second year oats forage was intercropped only with V. villosa. All intercroppings were compared with pure oat forage. The percentages of soil cover, were calculated useingCobcal software, based on photographic records. Results indicate that intercropping can be a possible strategy for Bermudagrass management. Vicia villosa behaved as a very good companion species, increasing considerablyground cover during all the production cycle.
