The effect of seed rate on grain yield and its components of three new variety and line of rainfed wheat
Abstract:   (3770 Views)
In order to investigate the effect of seed rate on yield and its components of dryland wheat genotypes a field experiment was conducted as factorial arrangement in a randomized complete block design (RCBD) with four replications during 1998-2001at Maragheh Agricultural Research Station, Dryland Agriculture Research Institute (DARI). The treatments included four levels of seed rates (250, 300, 350 and 400 seeds per squre meter) and three new dryland wheat genotypes (V1= Azar 2, V2 = Sbn//Trm/K253 and V3 = Sbn/1-27-56-4).Grain yield, plant height, kernel number per spike, spike number per squre meter, spike lenght and 1000KW determined from the middle of each plot. The results showed that seed rate of 300 seed per squre meter and Azar 2 (V1) had the greatest grain yield (1250kg.ha-1) and maximum water productivity (5.31 kg.mm-1), and can be recommend for areas of similar conditions.
