Effect of Different Ratios of Hungarian Vetch with Cereal Crop Mixtures on Hay Nutrient Value

Abstract: This study has been conducted in order to determine the variations in digestibility and energy values of hay depending on the application of Hungarian vetch-cereal crop mixtures at different ratios. The research has been carried out in Canakkale in 2009–2011. The study has been designed according to randomized complete block design, and the plots were arranged as single and mixed (3:1, 2:2, 1:3 Hungarian vetch: cereal)  crop sowing systems by using three replications with sowing Hungarian vetch mixing with barley, wheat, oats and triticale. Raw cellulose (RC), digestible dry matter (DDM), total digestible nutrients (TDDM), metabolic energy (ME), net energy (NEL) and relative feed value (RFV) like characteristics have been examined in this research. As the result of this research, the ratios of hay raw cellulose (RC) were not significantly important in accordance to different forms of sowing, while the values of DDM, TDDM, ME, NEL and RFV in hay were found higher in mixed sowing system than that of single sowing of cereal crops. In the study, it has been concluded that for being able to produce hay containing high nutrient value in the mixtures of Hungarian vetch with cereals then the mixture of wheat with Hungarian vetch with the ratio of 3: 1 would be suitable to sow.
