Lavanta Çeşitlerinin Bazı Tarımsal Özelliklerinin İncelenmesi

Abstract

During the period from 2014 to 2017 year in the region of Dobrich, Bulgaria, a field experiment has been conducted with the aim to determine some agricultural characteristics of lavender varieties. The following characters have been investigated: number of flowers/plant, length of the flowering stem, number of flower clusters/plant, weight of flowers/plant (g), yield of flowers (kg ha -1 ), essential oil content %, extraction essential oil yield (kg). The experiment has been carried out according the randomized block design in four replications and plot size of 10 m 2 . Four lavender varieties have been used-Hemus, Yubileyna, Druzhba and Sevtopolis. From the performed analyzes, it was established, that the variety Druzhba distinguished from the other varieties in term of yield of fresh flowers, not only by years, but also on average for the study period, as the higher productivity of this variety is due to the higher values of the structural elements of the yield. The highest percentage of essential oil content for the three-year period with 2.1% was realized from the variety Sevtopolis, and the lowest with 1.6% from the variety Hemus.
