The study was carried out to determine the effects of different sowing times (October and November) and plant densities (80, 100, and 120 seeds m −2) on hay yield and quality of some forage pea cultivars (Özkaynak and Taşkent) in 2018 and 2019 years of Eskisehir ecological condi- tions. The experiment was established in Randomized Complete Block Design with three replica- tions. Hay yield, crude protein, neutral detergent fiber, acid detergent fiber, and acid detergent lignin contents were investigated. Hay yield, acid detergent fiber, and acid detergent lignin con- tents were higher in 2018 (5139.2 kg ha −1, 31.76%, and 8.02%, respectively) but crude protein (13.89–14.44%) and neutral detergent fiber (37.52–37.77%) contents did not change significantly between the years. Cultivars and plant densities did not cause any significant variation on the examined characteristics but late autumn sowing caused a 1.51% increase in crude protein con- tent, which was significant. Neither late autumn sowing nor different plant densities caused any negative effects on hay yield and quality of forage peas. Therefore, forage peas could be sown in both October and November using any of the Özkaynak or Taşkent cultivars at 80 seeds m−2 plant density in Central Anatolia conditions.
