Effects of seeding rates on competition indices of barley and vetch intercropping systems in the Eastern Mediterranean

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