Productivity of plantations of sweet cherry (Prunus avium L.) in the Crimea depending on the methods of forming the crown

Abstract

The results of studies on the productivity of cherry trees on the rootstock of VSL-2, depending on the methods of crown formation. The objects of research were plants of varieties Krupnoplodnaya, Lyubava, Annushka, which are formed by the type: free-growing spindle (control), flattened spindle, weeping crown shape. The scheme of planting - 4.5 x 2.5 m. The results of the research showed that the average yield for the period 2013-2016 in the plantings of Krupnoplodnaya variety was 17.6 t/ha in the formation of free-growing spindles (control); 17,0 t/ha - flattened spindle and 19,1 t / ha - weeping crown shape. The average yield of varieties Lyubava and Anushka during this period did not exceed 7.9 t/ha, but they stand out for the quality of the fruit and are resistant to cracking and gray rot. The highest yield was found in varieties Lyubava version with a weeping crown shape (6.4 t/ha), in varieties Anushka - in the formation of trees on the type of flattened spindle (7.9 t / ha).
