Twelve durum wheat genotypes were evaluated for their grain yield and
related traits using two rates of nitrogen fertilizer application
(69 kg N ha﹣1 and 115 kg N ha﹣1) in a randomized complete block design with three replications. The
experiment was done on Vertisol at Adet Agricultural Research Center in the
main cropping season 2009. All agronomic traits respond positively to applied
nitrogen rates. The highest grain yield (33.8 Qt·ha﹣1) was reported from Asassa variety. Grain yield increased by 8.8 Qt·ha﹣1 with the increase of nitrogen rates by 46 kg N ha﹣1. Studied traits, except days to heading, grain filling period and
biomass production efficiency, others did not respond to the genotype by
nitrogen interaction effect. Grain yield was positively correlated with plant
height (r = 0.53), total plant
biomass (r = 0.81).
