Fruiting Period and Yield of Olive Varieties

The article presents the results of research on the fruiting period and yield formation of introduced olive (Olea europaea L.) varieties under the dry subtropical conditions of the Surkhandarya region of Uzbekistan. The relationship between the duration of the vegetation period, the sum of effective temperatures and productivity was evaluated for the varieties Krymskaya-172, Nikitskaya I and Nikitskaya II. The vegetation period was 191 days in Krymskaya-172, 187 days in Nikitskaya I and 192 days in Nikitskaya II, while the corresponding yields were 3.8, 4.0 and 4.6 t/ha. The results indicate varietal differences in adaptation and productivity under local climatic conditions.
