The effect of different nitrogen doses on yield and yield components of bergamot mint (Mentha citrata Ehrh)

In 2023, a study was conducted under ecological conditions in Eskişehir using the variety to investigate the effects of 4 different N doses (0,5,10,15 kg/da) . The experiment was set up with 3 replications according to a randomized complete block design at the Eskişehir Forest Nursery. This study examined the effects on parameters such as plant height, number of lateral branches, fresh herbage yield per plant, dry herbage yield per plant, dry leaf yield per plant, fresh herbage yield per hectare, dry herbage yield per hectare, dry leaf yield per hectare, and volatile oil content. The values obtained as a result of the study vary between 35.14-42.63 cm, 12.9-17.4 plant-1, 37.97-73.03 g plant-1, 16.05-27.58 g plant-1, 11.17-17.18 g plant-1, 626.00-1193.83 kg/da, 200.97-498.27 kg/da, 91.76-205.12 kg/da and 1.73-2.20 l da-1, respectively. According to the results of this research, very important differences were found in plant height, number of side branches, dry herba yield per plant, dry herb yield per plant, dry leaf yield per plant, fresh herba yield per decare, dry herba yield per decare and dry leaf yield per decare.As a result of the study, the highest was obtained from the application of 15 kg dose N.
