The Effect of Different Phosphorus Doses on Agronomic and Quality Characteristics of Coriander (Coriandrum Sativum L.)
(Aloki Applied Ecological Research and Forensic Inst Ltd, 2020) Izgi, M. N.
In a two-year study, under the environmental conditions of the plains of Mardin province in Turkey, the effects of different doses of phosphorus (0, 30, 60, 90, 120 kg ha(-1)) on the yield and quality characteristics of the coriander (Coriandrum sativum L.) were examined. Plant characteristics such as plant height, number of branches, number of umbels, thousand seed weight and seed yield were examined, besides quality characteristics such as essential oil rate and composition. The essential oil was isolated with a Clevenger apparatus from mature fruits. Essential oil components were determined with Gas chromatography-mass spectrometry (GC-MS). The results revealed that phosphorus doses affect the plant characteristics of coriander including plant height, number of branches, number of umbels and thousand fruit weight with positive significance. Fruit yield was not affected significantly. Phosphorus doses had a significant positive effect on essential oil rate. Increasing phosphorus doses affected rates of alpha-pinene, geranyl acetate and camphor positively. However, Linalool and gamma-terpinene were not affected by phosphorus doses significantly. The application of 120 kg phosphorus per hectare, which had the highest essential oil rate in both years, can be recommended in coriander farming.

Effects of Nitrogen Fertilization on Coriander (Coriandrum Sativum L.): Yield and Quality Characteristics
(Aloki Applied Ecological Research and Forensic Inst Ltd, 2020) Izgi, M. N.
Coriander (Coriandrum sativum L.) is a spice plant belonging to the Apiaceae family. In this study, the aim was to specify the effects of different nitrogen doses on the yield and quality properties of coriander. In this research; plant height, number of branches, number of umbels, thousand seed weight, seed yield, oil content, fatty acid composition, essential oil rate and essential oil composition were examined. The essential oil contents in coriander fruits was determined by Clevenger apparatus. Fatty oil was isolated by cold press. Essential oil and fatty oil compositions were determined by Gas chromatography-mass spectrometry (GC/MS-QP2020) device. While nitrogen doses did not positively affect fruit yield, they had a significantly positive effect on the herbal characteristics of coriander (plant height, number of umbels and thousand fruit weight). It was revealed that nitrogen doses had positive significant effect essential oil rate. Increasing nitrogen doses affected rate of linalool. Nitrogen doses had a significant effect only on butyric acid, and for fatty oil rate and other major fatty acids their effect was not significant. It has been determined that high fruit yields are obtained at 60 and 80 kg ha(-1) nitrogen applications and that the rate of essential oil and linalool is the highest at 100 kg ha(-1) nitrogen doses especially in the second year.
