Abstract

ABSTRACT
Nine varieties of the Yaka type (YK 7-4/2, YK-23, YK-48, JK-87, YK-68, YK 10-7/1, YK-261, YK-141 and YV 125/3), as well as one variety of the Prilep type (P-66-9/7), were taken as working material and their quantitative characteristics were analyzed: plant height with inflorescence, number of leaves per plant, dimensions of the leaves of the middle belt of the plant and yield of dry leaves per plant. As a control, for comparison, we took the variety of the Yaka type YV 125/3. In recent years in the Republic of North Macedonia, the most common variety is P-66-9/7, so we placed it in the same experiment as a second control variant. The experiment was set up at the Experimental Field of the Scientific Institute of Tobacco - Prilep in 2022 and 2023, in a randomized block design with four replications, using traditional agricultural practices. Measurements of the first three traits were made at the budding and flowering stages, and the dry leaf mass yield was determined during the manipulation of the cured tobacco. The results were statistically processed.
The aim of the investigation is, by presenting the obtained two-year results on quantitative characteristics, to provide useful information for the selection of oriental tobaccos, as well as to introduce, above all, foreign tobacco buyers to the Yaka-type varieties, which are characterized by a particularly pleasant aroma.
From the analysis of the results obtained from the comparative experiment, it can be concluded that the Yaka-type varieties do not have a significantly higher yield than the Prilep-type variety, with the exception of YK-87, which in 2022 gave a yield higher than that of P-66-9/7 with a significance of 5%). YK-87, YK-261, YK 10-7/1 and YK-141 give approximately the same yield as that of P-66-9/7, and significantly higher than the control variety YV 125/3. The seeds of these varieties can be offered to buyers of oriental tobaccos, in accordance with their wishes and needs.
