Considering the increase in the demand for organic agriculture in addition to reducing the
use of inorganic fertilizers in terms of maintaining the sustainability of the soils, the necessity of using
organic fertilizers is a reality. Animal wastes that cause environmental problems have an important
economic potential and can be used in fertilizer production. In addition to obtaining high yield and quality
products from potatoes, organic fertilization should not be neglected in order to grow and develop in a
healthy way. This research was carried out in Erzurum in 2021 to determine the effect of different organic
materials, which are wastes of animal origin, on the chlorophyll content of potatoes as fertilizer. Poultry
(chicken), ovine (sheep), bovine (cattle) and worm manures and their determined doses were applied as
organic fertilizers, individually and in combinations. The study was established according to the "Random
Blocks" experimental design with 3 replications. Chlorophyll contents (SPAD) were measured when the
plants were in full bloom. In the study, the chlorphyll content of potatoes varied between 46.6-55.9%.
Significant changes were determined in the chlorophyll content of potatoes with the application of organic
fertilizers alone or in combination. The highest values are from the application of cattle manure only
(55.9%), cattle + chicken (54.4%), vermicompost only (53.9%) and together with chicken manure (52.4%),
while the lowest application values were obtained in chicken manure only (46.6%), cattle + worm (47.3%),
sheep + worm (48.2%) and sheep + chicken + vermicompost (48.3%).
