Abstract:
A field experiment was conducted at Bouqa Farm, Faculty of Agricultural Engineering, Tishreen University, during the agricultural seasons of 2019 and 2020, by planting one line of barley and one line of triticale from the General Commission for Scientific Agricultural Research, in addition to common vetch Vicia sativa L., to study the effect of mixing ratios of each of barley and triticale with vetch on forage production and competition indices. The experiment was carried out according to a Randomized Complete Block Design (RCBD) design, with three replicates. The results indicated a significant effect of mixed cultivation in terms of the type of grass crop and its percentage in the mixture on the production of dry matter of the mixture, and the studied competition indices (grass competition coefficient, total relative yield, relative crowding coefficient, and percentage of vetch in the mixture). In both seasons, triticale in single cultivation significantly outperformed the rest of the studied treatments in terms of dry matter production, followed by the mixture consisting of 75% triticale and 25% triticale, which significantly outperformed all studied mixture treatments in terms of the percentage of legumes within the mixture, the total relative yield and the relative crowding coefficient, while barley grown with vetch at a mixing ratio of (75% B + 25% V) significantly outperformed the rest of the studied treatments in terms of the Competitive ratio. Based on the research results, it is suggested to grow triticale in fodder mixtures with vetch at a mixing ratio of 75% triticale + 25% vetch to obtain high fodder production.
Keywords: Common vetch, barley, triticale, fodder mixtures, competition indices.
