Failure to replace the decreasing plant nutrients in the soil with mineral and organic fertilizers leads to losses in soil fertility and consequently in the product. The use of environmentally friendly organic fertilizers that can be an alternative to the use of chemical fertilizers is of great importance for the realization of sustainable agriculture. This study, which was carried out to determine the effect of different doses of organic fertilizer (liquid seaweed) application on yield and fiber quality in cotton, was established in the 2018-2019 cotton growing season in Dicle University, Faculty of Agriculture, Field Crops Experimental areas according to the Split Plots Experimental Design in randomized blocks with 3 replications. In the study, varieties (BA440, BA119, Gloria) constituted the main plots and treatment doses (Control, 300ml, 200ml, 100ml) constituted the sub-plots. The treatments were carried out during the cotton combing period. The effects of organic fertilization on plant yield and fiber quality were examined. The effects of organic fertilizer doses on yield, fiber durability, ginning yield, first fruit branch internode height and boll number were found to be significant. In the study, the highest values of cotton mass yield were obtained from 300 ml/da dose application of BA119 variety with 493.69 kg/da; the highest ginning yield was obtained from 300 ml/da dose application of BA119 variety with 44.91%; the highest number of bolls was obtained from 300 ml/da dose application of BA119 variety with 14.4 pcs/plant; the most resistant fibers were obtained from 100 ml/da dose application of Gloria variety with 36.3 g/tex.
