Response of Two Wheat Cultivars (Triticum Aestivum L) To Amended Nitrogen Fertilizer on Yield and Grain Quality in Halfa Elgadidah Area

A field experiment was conducted for two consecutive seasons during 2011/2012 and 2012/2013 on the Demonstration Farm of the Faculty of Agriculture, University of Kassala at New Halfa.The objective of the study was to investigate the interactive effects of cultivars and chicken manure with nitrogen fertilizer on yield and grain protein content of wheat cultivars (Triticum aestivum L).The wheat cultivars (Nepta and Bohein) were used, and the nitrogen fertilizer levels were 0, 43, 86kgN ha -1 corresponding to N0, N1 and N2 without or with 2 tons of chicken manure ha -1 (M).The experiment was laid out according to split-plot design.Both cultivar, fertilizer treatments and their interactions showed significant increases in total leaf area duration and dry matter production.Also, Nebta cultivar out yielded Bohein by more than 20%.Moreover, addition of organic manure with high N level significantly increased grain yield by more than 88% and 50% relative to N0 treatment for Nebta and Bohein, respectively.The increase in grain yield was associated with significant increases in yield components (number of grains plant -1 and 1000-grain weight) and grain protein content.
