Response of Bread Wheat Yield and Quality to Source of N Fertilizers

Abstract

An experiment was carried out through 2019.-2020 on farmer field in Eastern Husaiba, near Habaniya, Anbar governorate. The objectives were, to test field performance, and quality of five bread wheat (Sham6, Ibaa99, Bora, Buhooth22 and Abu-Gharib3) in response to source of nitrogen fertilizers. These cultivars were fertilized by three sources of N (glutamic acid, humic acid, and urea). Results showed significant differences among cultivars in most traits studied, Sham6 recorded higher grain/spike (52.2), grain yield (6.46 t/ha), and total dry biomass (18.2t/ha). Buhooth22 gave better wet protein (35.78%) and gluten (15.45%). Bora cv. gave higher gluten index (74.7%). Humic acid gave higher grain/spark (45.6), yield (6.7 t/ha), biologically biomass (17.7t/ha), wet gluten (35.8%) and gluten (14.35%). Interactions between cultivars and N source were significant. Sham6 were gave higher values of grain yield and total biological masses.
