Abstract

Agricultural areas that rely on a single crop for production experience negative soil characteristics, while the benefits of these locations are further diminished by short-term winter fallows. In the ecological conditions of the Aegean Region, cotton-cotton and maize-maize production patterns can be given as examples of this type of production. With the adoption of a sustainable agriculture approach in recent years, the use of winter annual forage crops is quite important in terms of preventing this situation. The inclusion of forage pea in the production patterns both contributes positively to the soil properties and is a potential source of quality roughage. In line with this information, 8 different forage pea varieties (Kirazlı, Ulubatlı, Ürünlü, Gölyazı, Özkaynak, Töre, Taşkent, GAP Pembesi) were harvested at 3 different phenological stages (10%, 50%, 100% flowering) in Aydın ecological conditions. Some agronomic characteristics such as plant height (cm), stem diameter (mm), herbage yield (kg da-1) were measured in the experiment. After the measurements, ADF (%), NDF (%), ADL (%), protein properties and relative feed value were determined. While lower values were found in terms of yield and fiber values in early mowing, higher values were found in terms of crude protein ratio and relative feed value. At the same time, the variety-environment interactions showed differences in both years. Our results demonstrated that 100% flowering is preferable in terms of yield. Differences were observed among the varieties according to yield and quality characteristics. In terms of herbage and crude protein yields, Töre, Taşkent and GAP Pembesi were the most prominent common varieties. In terms of relative feed value, Ulubatlı and Ürünlü are the varieties with high values.
