Effects of Phosphorus Fertilization on Seed Yield of Sainfoin(Onobrychis Sativa l.)

Abstract
This research was conducted to determine the effects of five phosphorus doses (0, 40, 80, 120 and 160 kg ha-1) on seed yield and some yield components of sainfoin(Onobrychis sativa L.) under Mediterranean region of Turkey. The experiment was established in a randomised complete block design with three replications. Seed yield, raceme number per plant, raceme number per m2, fruit weight per raceme, fruit weight per plant and 1000-fruit weight were determined. Phosphorus rates significantly affected all components determined in sainfoin. Phosphorus applications increased seed yield, raceme number per plant, raceme number per m2, fruit weight per raceme, fruit weight per plant and 1000-fruit weight. At the end of this research, 120 kg ha-1 phosphorus dose is recommended for high seed yield in sainfoin. Key words - Sainfoin, seed yield, raceme number per plant, 1000-fruit weight.
