The importance of organic fertilizers for sustainable agricultural production is an undeniable fact. The aim of this study is to determine the effects of different organic fertilizers on the growth and quality properties of maize plants. Three different types of organic fertilizers; cattle manure, vermicompost and leonardite, and their doses of 2.500, 5.000, 7.500 and 10.000 kgha-1 were used in the experiment. In addition, conventional production and non-fertilized production were used as control applications. The experiment was carried out in a randomized complete block design with three replications. The experiments were repeated to assess the residual effects of the treatments. Fertilizers were applied in 2018 to determine the residual effects of organic fertilizer applications in the second year. In the research; plant height, ear diameter, ear grain weight, 1000 grain weight, grain yield, protein ratio, oil ratio and starch ration were examined. The aim of this study is to determine the effect of different organic fertilizers on the yield components and grain content of the corn plant. These features varied between 180.72-157.87 cm, 39.38-33.59 mm, 117.1-62.2 g, 261.2-237.1 g, 4416.8-1712.9 kg ha-1, 7.8-5.9%, 2.5-2.1% and 74.7-73.8%, respectively. According to the results, the 2500 kgha-1 and 5000 kgha-1 doses of vermicompost had the highest values for the oil ratio and protein ratio, on the other hand the leonardite application of 10.000 kgha-1 for the starch ration had the highest value. Generally, conventional fertilizer application had the highest values for yield components.
