Résumé
This study was carried out according to the experimental design of random blocks split plot design in the wheat production season of 2016/2017 at Adnan Menders University Agricultural Faculty Research and Application Farm. Ceyhan 99 variety was used as a wheat variety in the experiment. Purpose of the study 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 t/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 are obtained between applications. Plant height, number of spikes per square meter, number of grains per ear, thousand grain weight, test weight, ear weight,ear yield, flag leaf area, yield, grain ash ratio and grain fibre ratio parameters are affected statistically significant by liquid biogas waste applications. The mineral nitrogen doses possitively affected all other yield and quality parameters except starch, fibre, protein ratio in grain and field emergency parameters. Better results were usually obtained in the experiment from 3 t/da liquid biogas waste dose and 18 kg/da mineral nitrogen dose combination.

Mots clés : Wheat, quality, yield, mineral nitrogen fertilizer, biogas, liquid biogas waste.
