This study was carried out in order to determine the effect of organic liquid fertilizer applications on grain yield, yield characteristics and some quality trait of wheat in different periods in organic agriculture trial area. The trial was conducted in four replications according to a split-plot design in randomized blocks in trial area of the vocational Akcakale high school during the 2016-2017 and 2017-2018 growing season. Solen 2002 and Edessa wheat varieties and organic liquid fertilizer and barnyard manure were used as materials in the research. Organic liquid fertilizer was applied in five different periods such as control, tillering, beginning of the bolting, the end of the bolting and the hearing, provided that the dose remained the same. According to the results of the research, the highest values were obtained in the end of the bolting of Solen-2002 variety in terms of grain yield and yield components (spike length, spikelet number, number of grains per spike, grain weight per spike, plant height, hectoliter weight and thousand kernel weight). According to the results of two years, the highest grain yield (530.43 kg/da-1) was obtained in the end of the bolting application of Solen-2002 variety. Since the first year of the study was warmer and more drought than the second year, While the yield and yield components decreased, the quality characteristics (protein and dry gluten ratio) increased. Due to the temperatures, Edessa variety had higher protein and dry gluten ratios than Solen-2002 variety. |
