Economic efficiency of various harvesting methods of raspberry varieties in the production conditions of the Republic of Belarus

The article presents the results of a production study for suitability of zoned and potential raspberry varieties to mechanized harvesting. Varieties of autumn raspberry ‘Polka’, ‘Herakl’, ‘Zeva Herbsternt’ have a complex of traits that determines suitability for mechanized harvesting: compact habit of the bush, height ‒ 165‒173 cm, shoot diameter ‒ within 14‒15 mm, row width ‒ within 37‒40 cm, the completeness of berry harvesting with a half-row harvester ‛Jarek-5’ ‒ 59.5‒65.1 %, mechanical shoot damage ‒ no more than 22 %, yield – 6.9‒10.4 t/ha. Thus, the varieties are suitable for production cultivation with mechanized harvesting in the conditions of the central fruit-growing zone of the Republic of Belarus.

Cultivation of varieties ‘Polka’ and ‘Herakl’ with mechanized harvesting is highly profitable both on small (5‒10 hectares) and on large areas (15‒30 hectares) ‒ the level of profitability is 135.9‒156.2 % and 146.3‒166.8 %, respectively. Cultivation of the late variety ‘Zeva Herbstent’ is desirable in an area of at least 15 hectares with a profitability level of 88.4-95.6 %.
