The Effect of Different Doses of Liquid Biogas Fermentation Wastes on Yield and Quality of Bread Wheat (Triticum aestivum L.)

The study was carried out according to the experimental design of random blocks split plot design in the wheat production season of 2016/17 at Adnan Menderes University Agricultural Faculty Research and Application Farm. Ceyhan 99 variety was used as a wheat variety in the experiment. Purpose of the study is determination of the effects of three different mineral nitrogen fertilizer doses (0, 9, 18 kg/da) and five different liquid biogas waste doses applications (0, 1, 2, 3, 4 ton/da) and their combinations on yield and quality in wheat plants besides investigate the effects of the use of liquid biogas waste in agricultural production on soil fertility. When the results are summarized bread wheat yield and quality parameters are affected by liquid biogas waste and mineral nitrogen fertilizer applications and statistically differences were obtained between applications. Number of spikes per square meter, thousand grain weight, test weight, flag leaf area and grain yield parameters are affected statistically significant by liquid biogas waste applications. The mineral nitrogen doses positively affected all other yield and quality parameters except protein ratio. Better results were usually obtained in the experiment from 3 ton/da liquid biogas waste dose and 18 kg/da mineral nitrogen dose combination
