Effect of Applications of Chemical and Organic Fertilizer on Yield and Essential Oil Ratio of Coriander (Coriandrum sativum L.) Plant

Abstract

This study was carried out to determine the effects of different combinations of chemical and organic fertilizers on yield and essential oil ratio in coriander plant. Research, 2019-2020 vegetation period situated in Turkey's semi-arid climate prevails that was conducted in Southeastern Anatolia Region Siirt conditions. A total of 11 subjects, different combinations of chemical and organic fertilizers, formed the subject of the study in the study, which was established with 3 repetitions according to the randomized blocks trial design. According to the results of the research, the effect of chemical and organic fertilizer combinations on plant height and essential oil ratio in coriander plant is statistically insignificant. The number of seeds in the main umbrella and biological yield at p<0.05 level, the number of umbellet in the main umbrella, harvest index, seed and essential oil yield at p<0.05 level were statistically significant. In the research, the highest number of umbellet and seeds in the main umbrella were vermicompost (100%), harvest index (50% NPK + 50% chicken manure), seed yield (50% NPK + 50% chicken manure and 75% NPK + 25% chicken manure) and essential oil yield (50% NPK + 50% chicken manure). According to the research subjects, the plant height is 64.37-75.90 cm, the number of umbellet is 5.40-6.27 in the main umbrella, the number of seeds in the main umbrella is 32.47-41.53, the biological yield is 411.83-687.90 kg/da, the seed yield is 101.05-186.91 kg/da, harvest index, 22.23-36.28%, essential oil rate 0.30-0.32%, essential oil yield varied between 0.30-0.60 L/da. It was concluded that chemical fertilizer and organic fertilizer applications in coriander cultivation in semi-arid climatic conditions increase yield and some yield criteria.
