Abstract
Nowadays, the use of slow-release nitrogen fertilizers is considered a good alternative, especially to reduce the negative environmental effects of nitrogen and to increase its usage efficiency. Furthermore, research in this area is increasing day by day. The study is a model study that aims to compare the wheat development, nitrogen (N) uptake, and utilization efficiency of slow-release urea (SRU) fertilizer, which is coated with a biodegradable natural material based on sodium alginate and enriched with additive components consisting of a mixture of humic acid, lysine HCL, and gluconic acid, with conventionally widely used urea (CU) fertilizer, which is traditionally widely used. In a pot experiment conducted under greenhouse conditions using the Kayra bread wheat (Triticum aestivum L.) variety, slow-release and conventional urea fertilizers were applied in increasing doses (0, 8, 16, 24 kg da⁻¹) in divided applications. and certain growth parameters (plant height, root length, root, stem, ear fresh and dry weights) and quality criteria (grain number, 1000-grain weight, and protein content) were determined. According to the results of the study, it was determined that the application of 16 kg da⁻¹ of SRU fertilizer could increase N uptake and grain protein content in wheat by approximately 5–10%, chlorophyll index and yield components by 10–15%. In this context, it is recommended that the long-term performance and potential environmental/economic impacts of SRU fertilizers formulated with different components and additives be verified through multi-location field trials on different soil types, climatic conditions, and wheat varieties.
