The effectiveness of biostimulator Goemar BM 86 on apple fruit yield and quality

Abstract

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.
