Determination of Agricultural Characteristics of Different Mint (Mentha sp.) Species in Ordu Ecological Conditions

Abstract

This study was carried out at Ordu University, Field of Agricultural Research and Application in 2016-2017, in order to determine the agricultural characteristics of some mint species (Mentha piperita, Menta spicata and Mentha longifolia) according to “Completely Randomized Design” with three replications. Plant height, fresh herb yield, dry herb yield, fresh leaf yield, dry leaf yield, essential oil yield and essential oil ratio were investigated. In both years of the experiment, M. spicata and M. longifolia were harvested 2 and 4 times, respectively, M. piperita 1 times in 2016 2 times in 2017 was harvested. As a result of research the difference in term of plant height between species was determined only in the first harvest in the first year. In the first year of the experiment, the total fresh herb yield, total dry herb yield, total fresh leaf yield, total dry leaf yield of Mentha piperita were 2.442.73 kg/da, 585.70 kg/da, 1.120.67 kg/da, 266.87 kg/da, respectively, while total essential oil yield was 6.40 lt /da. Also in the second year of the experiment, high values were obtained from Mentha spicata in terms of total fresh herbage yield (920.37 kg/da), total dry herb yield (247.93 kg/da), total fresh leaf yield (502.5 kg/da) and total dry leaf yield (149.93 kg/da). M. longifolia plant was ranked first in terms of total essential oil yield (3.48 lt / da and 3.19 lt / da) in terms of the total essential oil ratio due to 3.47 lt / da in the research year of 2017.
