Nowadays, raspberry and blackberry are one of the most desired fruits for fresh consumption even beyond the ripening season. To meet the market need and support farmers with new growing solutions and organic measures applied in the orchards, in early 2019, we set out couple of experiments to demonstrate the viability of such innovative crop systems. Two new raspberry varieties 'Polonez’ and 'Poemat’ and one blackberry variety 'Navaho’ were subject of pot system in high tunnel protected area with Nectarine plastic film. Substrates were composed by different share of organic peat, Biohumus and mycorrhiza. In each pot of 20 litres volume were planted two root cubes and a trellis system was provided. A mix of organic fertilizers were applied during the vegetation period and the plants response was evaluated in terms of growth and fruiting capacity. By the end of the year, 'Poemat’ was picked for 5 times and 'Polonez’ for one time more. No fruits available at ’Navaho’ in the first year. The total number of harvested fruits were higher at 'Polonez’ but the size was lower comparative to 'Poemat’. Longer canes were measured at 'Polonez’ but 'Poemat’ assembled more growths in terms of total annual growths due to a better ramification can. The Biohumus positively affect the growths of the plants independent of the fertilization scheme.
