dc.description.abstractForage mixtures are common agricultural practices for the energy and protein needs of animals. In this study, common vetch (Vicia sativa L.), Hungarian vetch (Vicia pannonica L.), and barley ( Hordeum vulgare L.) mixtures in diferent seeding rates were investigated in terms of forage yield and quality. In order to evaluate the efect of vetch, cereal intercropping and the competition/ economic indices of 8 diferent legume–barley mixtures, along with their pure stands, were assessed during the 2008–2009 and 2009– 2010 growth seasons in the Eastern Mediterranean region of Turkey. Te feld experiment was arranged as a randomized complete block design with 3 replications for each year. Intercropping indices were calculated by means of land equivalent ratio (LER), aggressivity (A), crowding ratio (CR), and actual yield loss (AYL). Competition indices revealed that both the common vetch–barley and the Hungarian vetch–barley intercroppings at a seeding ratio of 80%:20%, respectively, were advantageous due to their high yield, land use efciency, and economic value compared to other mixtures or pure stands. All samples were analyzed for quality parameters such as dry matter (DM), crude protein (CP), neutral detergent fber (NDF), and acid detergent fber (ADF) content. While digestible dry matter (DDM) content did not difer among treatments, CP, NDF, ADF, TDN (total digestible nutrients), DDM, RFV (relative feed value), and NE1 (net energy for lactation) content signifcantly difered among the diferent vetches–barley mixtures (P < 0.01). Te results emphasize that both vetch species combined with barley and using the seeding ratio of 80% vetch:20% barley should be proftable for farmers in terms of implementation and maximum yield per unit area under Eastern Mediterranean conditions.en_US
