Effects of Seeding Rates and Sowing Times on Grain Yield and Yield Components in Rye (Scale cereale L.) Under Dry Condition

Rye is one of the most important cereals for marginal land and cold climates in Turkey. A 2 year experiment was conducted Kırşehir, Turkey, to determine impact seeding rates sowing times on rye (Secale cereale L. ‘Aslım 95). seed sown different (1th October, 15th 1th November, November December) at four (300, 400, 500 600 seeds m−2). split-plot design used, with as main plots randomized subplots. Grain yield tended increase earlier dates higher rates, based two-year means. Seeding interaction effects grain were significant. Therefore, highest 397.7 kg da-1 obtained from rate (600 m−2) second date (15th October). In contrast, lowest (92.8 da-1) delayed dates. It concluded that present study showed reduction depended time which led a significant number fertile spike per unit area.
