This study was carried out with the aim of determining the effect of different amounts of humic/fulvic acid application on the yield and some quality traits of two bread wheat cultivars in Yozgat-Sarıkaya ecological conditions between 2013 and 2015 growth seasons. Experiments were established using split block design with three replications. In this study, spike length, spike number per square meters, grain yield, test weight, 1000 kernel weight, protein content, Zeleny sedimentation value, wet gluten content, fat ratio, starch content, ash ratio, ADF and NDF value were investigated. The effect of humic/fulvic acid application on plant height, spike number per square meters, grain yield and thousand kernel weights were statistically significant at 1% level. According to the average of two years, the highest grain yield was obtained with 392.2 kg da-1 by applying 300 ml of humic/fulvic acid per decares. [ABSTRACT FROM AUTHOR]
