Abstract

(Background:) Raspberry (Rubus idaeus L.) is very popular with consumers around the world for its intense flavor, attractive appearance and health benefits. In recent years, interest in healthy eating and natural products has increased, and raspberry fits perfectly into these trends, which translates into its greater importance on the consumer market. (Aim) The aim of the study was the commodity evaluation of raspberry fruits bearing fruit on 2-year-old shoots, cultivated under the conditions of varied nitrogen fertilization against the background of constant phosphorus-potassium fertilization. The first-order factor were cultivars ('Laszka' and ‘Glen Ample’), and the second-order factor was nitrogen fertilization (0, 50, 100 and 150 kg N ha-1), against the background of constant phosphorus-potassium fertilization (100 kg P2O5 and 120 kg K2O ha-1). The experiment was set up in a dependent split-plot design, in 3 repetitions. (Results) The importance of raspberry on the consumer market was shaped by: taste and quality of fruit, health benefits, naturalness and freshness, universality of use, availability and nutritional trends. (Conclusion) The tested cultivars were characterized by similar production and quality capabilities. Fertilization of the tested cultivars with a dose of 135 kg N·ha-1 turned out to be justified in terms of yield. Increasing nitrogen doses resulted in a significant increase in fresh fruit yield and 1000 fruit weight. Different doses of nitrogen increased fruit resistance to mechanical damage, firmness and improved quality indices.
