Effects of Gypsum Apllication and Mixture Rates on Forage Yields of Alfalfa (Medicago sativa L.) and Smooth Brome (Bromus inermis Leyss)
(Kahramanmaras Sutcu Imam Univ, 2012) Erol, Taskin; Sevimay, Cafer Sirri
In this study alfalfa (Medicago sativa L.) which is legume forage species and smooth bromegrass (Bromus inermis Leyss.) which is forage grass were used in order to determine the effect of different species mixture rates and increasing levels of applied gypsum on yield and yield components between 2003 and 2005 at Ankara University Agricultural Faculty, Research Farm. The experiment was established in split-plot design on three replications. Each species was seeded as monocropping and mixtures of 75% alfalfa + 25% smooth bromegrass, 50% alfalfa + 50% smooth bromegrass and 25% alfalfa + 75% smooth bromegrass into sub-plots. However four different gypsum applications (0, 10 kg da-1, 20 kg da-1 and 30 kg da-1) were placed on main plots. According to research results, mixture rates of species were found as statistically significant on green yield, hay yield, dry matter yield and crude protein yield. The highest yields were obtained the mixture of 25% alfalfa + 75% smooth bromegrass. In the mixtures while alfalfa ratio was higher on seeding, the ratio of smooth bromegrass was lower on harvest.
