The research was carried out to determine hay yield and nutrient content of Phacelia tanacetifolia Bentham harvested at budding, 50 % of flowering and full flowering stages in 2017 and 2018 in the ecological conditions of Kahramanmaras. According to the results, plant height, fresh hay yield and dry hay yield ranged from 40.03-83.12 cm, 535-1332.3 kg da-1 and 69.36-338.48 kg da-1, respectively. When chemical constituents were taken into consideration, crude ash (HK), crude protein (HP), ether extract (HY), acid detergent fiber (ADF) and neutral detergent fiber (NDF) ranged from 14.05-19.17, 6.45-9.65, 2.20-3.05, 25.4-30.63 and 41.49-47.84%, respectively. The gas production, methane production, metabolizable energy (ME) and organic matter digestibility (OMSD) of Phacelia tanacetifolia Bentham ranged from 41.70-48.18 ml, 4.62-5.19 ml, 8.24-9.32 MJ /kg DM and 64.01-74.53 %, respectively. Although plant height, hay yield, cell wall contents increased with increasing maturity, crude protein, metabolizable energy and organic matter digestibility decreased. Therefore, it is recommended that Phacelia tanacetifolia Bentham can be harvested in the first two vegetation periods in order to obtain good quality hay for ruminant animals.
