In this study, usability of liquid animal manure used for top-dressıng in cotton was discussed. The experiment was established in Nazilli Cotton Research Station. The trail consisted of 6 subjects, 2 of them were control subjects and 4 of them were liquid animal manure dose subjects. Liquid animal manure doses were 4, 8, 12 and 16 kg N/da, and control applications were 0 and 9 kg N/da (chemical fertilizer). In the study, earliness, number of open boll, number of closed boll; ginning outturn, 100 seed weight, fiber strength, fiber length, fiber fineness values were analyzed. As a result of the study, it was determined that liquid animal manure applications had positive effects on ginning outturn, and 100 seed weight. Animal manure applications had same class intervals with chemical fertilizer applications on quality parameters and there was no statistically difference between them.
