Abstract
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.

Abstract
Organik gübrelerin sürdürülebilir tarımsal üretim için önemi yadsınamaz bir gerçektir. Bu çalışmanın amacı, farklı organik gübrelerin mısır bitkilerinin büyüme ve kalite özellikleri üzerine etkilerini belirlemektir. Çalışmada üç farklı organik gübre (sığır gübresi, vermikompost ve leonardit) ve bunların dozları (2.500, 5.000, 7.500 ve 10.000 kgha-1) kullanılmıştır. Ayrıca kontrol uygulamaları olarak konvansiyonel uygulama ve gübresiz uygulama yapılmıştır. Deneme tesadüf blokları deneme desenine göre üç tekerrürlü olarak yürütülmüştür. Organik gübre uygulamalarının ikinci yıldaki etkisini belirlemek için 2018 yılında gübrelemeler tamamlanmış olup, 2019 yılında gübreleme yapılmamıştır. Araştırmada; bitki boyu, koçan çapı, koçanda tane ağırlığı, 1000 tane ağırlığı, tane verimi, protein oranı, yağ oranı ve karbonhidrat oranı özellikleri incelenmiştir. Bu özellikler sırasıyla 180.72-157.87 cm, 39.38-33.59 mm, 117.1-62.2 gr, 261.2-237.1 gr, 4416.8-1712.9 kgha-1, %7.8-5.9, %2.5-2.1 ve %74.7-73.8 arasında değişim göstermiştir. Elde edilen sonuçlara göre yağ oranı ve protein oranı açısından vermikompostun 2.500 kg ha-1 ve 5.000 kg ha-1 dozları en yüksek değerlere sahip olurken, karbonhidrat oranı için 10.000 kg ha-1 leonardit uygulaması en yüksek değere sahip olmuştur. Genel olarak bitkisel özellikler açısından en yüksek değerler ise konvansiyonel gübreleme uygulamasından elde edilmiştir.
