OpenAlex English

Objective: The objective of this was to identify the impact of various organic fertilizers on the yield and quality characteristics of Lippia citriodora L. plants and assess their adaptability under the ecological conditions of Aydın. Furthermore, it was also aimed to provide information on the potential of organic fertilizers to enhance crop productivity by minimizing the employment of chemical fertilizers. Material and Methods: The study was conducted for two years (2018-2019) in Aydın ecological conditions. Six different organic fertilizers and one control were tested in the study, these are microbial fertilizer, animal-based liquid organic fertilizer, solid seaweed fertilizer, animal manure compost, leonardite and plant-based liquid organic fertilizer. Research Findings: Organic fertilizers have a significant effect on all measured traits as compared to control, it may be due to biofertilizers can increase photosynthetic texture by increasing nitrogen, phosphorus and sulfur uptake, which these elements play an important role in chlorophyll production and required enzymes production. This can be the reason for obtaining positive effect of biofertilizers on plant growth and development. Conclusion: Overall, findings suggest that the use of humic acid-containing fertilizers and proper organic fertilizer management can improve the growth and yield of Lippia citriodora L. plants.
