A Research on Yield and Yield Components of Some Two-Rowed Barley Varieties (Hordeum Vulgare L. Conv. Distichon) in Van Ecological Conditions

Abstract

This research was conducted during the 2004-2005 and 2005-2006 growing seasons at one site in Van Province. The experimental design was a randomized complete block with four replications and thirteen barley cultivars (Tokak 157/37, Tarm-92, Orza-96, Bulbul-89, Yesevi-93, Aydanhanim, Kalayci-97, Karatay-94, Efes-3, Efes 98, Anadolu 98, Cildir-02 and Zeynelaga) were used in the study. There were significant differences in tested characters among barley cultivars. According to two-year average, 2 days to headings ranged between 179.3 (Tarm-92) and 189.7 (Bulbul 89) days; spike number per m(2), 249.3 (Aydanhanim)- 560.7 (Tarm-92); culm length 51.2 (Cildir-02) -64.9 (Karatay-94) cm; spike length 5.83 (Kalayci-97))- 7.26 (Aydanhanim) cm; grain number per spike 16.32 (Tarm-92)-20.24 (Efes-98); grain weight per spike 0.73 (Tarm-92)- 0.99 (Aydanhanim) g; thousand grain weight 41.70 (Tarm-92)-46.32 (Aydanhanim) g; seed yield 197.30 (Zeynelaga)-319.70 (Tarm-92) kg da(-1) and harvest index 23.11 % (Yesevi-93)- 36.43 % (Kalayci-97). It was concluded that cv Tarm-92, cv Orza-96, cv Tokak 157/37 and cv Bulbul-89 had higher yield than other cultivars in Van regional conditions.
