Effect of Different Organic Fertilizers on Bread Wheat (Triticum aestivum L.) Productivity

Organic fertilizers are the basis of sustainable agriculture and an important resource in plant nutrition as well. The research was conducted out in the greenhouse conditions of the Dicle University Faculty of Agriculture, Diyarbakır, Turkey in 2020. The effects of 14 different organic fertilizers on grain yield, yield components, morphology and physiology properties of bread wheat (Triticum aestivum L) were examined. It was found that sheep manure (3,56 g/plant) among - used fertilizers have a greater effect on both the growth and yield components of wheat in comparison with other organic fertilizers. The grain yield and biomass yield obtained from sheep manure among organic fertilizers have been determined to be competitive with commercial fertilizers. It was revealed that certain organic fertilizers had no effect on grain yield or biomass yield as compared to the control level of no fertilizers. According to the research results, it would be appropriate to use chicken and sheep manure in order to obtain an optimal wheat yield in the organic farming system.
