Influence of Goemar BM 86 biostimulator on productivity and quality of fruits of the apple Gala Buckeye variety

Abstract

The preparations containing algae from Ascophyllum Nodosum class are used to increase the degree of flower setting, stress tolerance and productivity of apple-tree plantation. Studies were conducted on the variety of apple trees Gala Buckeye in the period 2021 with bio regulator Goemar BM 86 at a dose of 2.0 and 3.0 l/ha. The highest results for maintenance of physiological balance between growth, fruiting and regular yields in apple trees were obtained when using a dose of 3.0 l/ha, applied three times by leaf spraying. The first treatment should be carried out at the beginning of vegetation, the second - when the buds swell, and the third - after flowering.
