Özet
The present study was conducted during the 2004-2005 and 2005-2006 growing seasons at one site in Van Province and the experimental design was a completely randomized blocks of split plot a with three replications. Four triticale cultivars (Karma-2000, Presto, Tatlicak-97, Mikham-2002) were grown with six sowing rates (250, 350 450, 550, 650, 750 seed/m(2)) for determining of the most suitable seeding rates for the cultivars in terms of yield and yield components. Moreover, all yield components in varieties that investigated in the present study differed with seeding rates in two seasons. The highest grain yield was obtained in Mikham-2002 with 328.3 kg da(-1) at the seed densities of 550 seeds m(-2) in 2004-2005. Grain yield in 2005-2006 was the highest in Presto with 303.0 kg da(-1) at the seed density of 650 seeds m(-2). Consequently, seed yield and plant height and increased with optimum seeding rates, and then they decreased with higher seeding rates. Spike number per square meter increased in all cultivars, whereas grain number per spike, grain weight per spike and 1000 grain weight declined with the increasing of the seeding rates.
