Effect of zinc on the growth ,chemical composition and anatomical structure of barley (Hordeum vulgare L.C.M. var.) grown in saline medium

Research was conducted to determine the quality and chemical composition of silages obtained by mixing in different ratios of narbonne vetch (Vicia narbonensis L.) and barley (Hordeum vulgare L.) grown in rabi season of 2017-2018 in Eastern Anatolia, Turkey. In the study we studied the pure sowings of barley and narbonne vetch and their mixtures (20, 30, 40, 50, 60, 70, 80% of narbonne vetch (N) + 80, 70, 60, 50, 40, 30, 20% of barley (B). The values of ADF (acid detergent fiber), NDF (neutral detergent fiber), DDM (digestible dry matter), DMI (dry matter intake), DM (dry matter), CP (crude protein) and RFV (relative feed value) of silages of analyzed were respectively 33.38, 33.73, 62.89, 3.57, 24.69, 15.50%, 174.64. We also founded that LA (lactic acid), AA (acetic acid), BA (butyric acid), PA (propionic acid) and Ca, P, Mg, K and pH of silages investigated were respectively 1.60, 0.57, 0.42, 0.06, 1.17, 0.53, 0.25, 3.51% and 3.80. Our results shows that silages with high narbonne vetch were higher quality values for CP, ADF, NDF, DM, RFV, DDM, DMI, Ca, Mg, LA which determined chemical composition and feeding quality of silages. As a result, it is suggested that mixture silages with narbonne vetch (80%) and the barley ratio (20%) have important advantages for some properties of silages.

Acid Detergent Fibre

Barley (Hordeum vulgare L.) is a major feed in the Maritime region of Canada, but information on the chemical composition of barley cultivars grown in the Maritimes is lacking. Therefore, a study was undertaken to determine if starch, protein, neutral-detergent fibre (NDF), and acid-detergent fibre (ADF) of barley vary from region to region in Canada and to determine if barley cultivars that originated from Eastern Canada exhibit different chemical composition than those that originated from Western Canada. The chemical composition of two-row and six-row, covered and hulless, and feed and malting cultivars were also compared. Seventy-five cultivars were tested in eight environments (i.e. Charlottetown, Ottawa, Brandon, and Bentley in 1991 and 1992). These cultivars were classified into eight classes in four comparisons: eastern vs. western, two-row vs. six-row, hulless vs. covered, and feed vs. malting. Charlottetown grains were relatively low in protein, high in starch, and intermediate in NDF and ADF in comparison with grains produced at the other three locations. This suggests that more research in cultivar development and crop management is needed to increase the protein concentration of barley in the Maritimes. On average, two-row cultivars contained more starch and less fibre than six-row cultivars. Eastern two-row cultivars contained more protein than western two-row cultivars. As expected, hulless barleys contained more starch and protein, but less fibre than covered barleys. Canadian barley cultivars exhibited considerable variation in chemical composition. The cultivar x environment interaction was much smaller than the cultivar effect. Therefore, it is important to identify barley cultivars with high nutritional quality for use in commercial production. Key words: Barley, Hordeum vulgare L., cultivars, starch, protein, fibre
