AGRICULTURAL PERFORMANCE OF OIL-BEARING ROSE UNDER ORGANIC FERTILIZATION

Scientists today are focusing on new agricultural practices to enhance the yield and quality of medicinal plants.The products derived from these plants are valuable raw materials for the pharmaceutical and cosmetic industries, and ensuring their organic origin is a top priority.The use of organic farming practices corresponds to the objectives of the Green Deal and helps to provoke the natural fertility of the soil.In a dynamically changing climate, proper and appropriate fertilisation contributes to the better adaptation and development of crops.This study aims to examine whether different organic fertilizers affect the productivity and quality of essential oil in Damask rose.The experiment was conducted using a randomized complete block design with three replications for three years.The following organic fertilizers were utilized: dried poultry manure Polynamatura NP, bone meal OrgaNexport N:P 10:8, and vermicompost Biohumus, each applied at their respective doses.Results showed that fertilization with these organic products significantly increased the productive potential and the quality of oil-bearing roses.Among the fertilizers, bone meal had the most positive impact on productivity and essential oil yield.The highest essential oil quality was obtained from the variants treated with bone meal and vermicompost, and they could be recommended for sustainable rose production.
