Only Abstract
Mostrar más [+] Menos [-]The Gala Buckeye apple variety grafted on the M9 rootstock was taken as the object of study. Crown shape vertical axis. Planting distance of 3.5 x 0.8 m. To study the degree of binding and fruit production, the following variants were tested: 1. Control - no treatment; 2. Goemar BM 86, 2.0 l/ha; 3. Goemar BM 86, 3.0 l/ha. The amount of solution administered 1000 l/ha. The investigations carried out show that a smaller number of fruits in the crown were recorded in the control variant, 57 pcs/tree, compared to the variants treated with the biostimulator Goemar BM 86, 65-70 pcs/tree, where an increase with 14.0 - 22.8% compared to the control variant. The highest number of fruits in the crown of the tree was obtained in the variant treated with the biostimulator Goemar BM 86 in a dose of 3.0 l/ha - 70 pcs/tree. The study carried out on the degree of flowering showed that in the control variant, the given indicator was 9.3%, but in the variants treated with the biostimulator Goemar BM 86 it increased to 10.4-11.6%. Higher values of the degree of binding of flowers was recorded in the Goemar BM 86 variant, in the dose of 3.0 l/ha, constituting 11.6%. The variant treated with the Goemar BM 86 biostimulator at a dose of 2.0 l/ha recorded average values (10.4%) between the previous variant and the control variant.
