Production of planting material of raspberry variety glen ample in the North Montenegro

Abstract

The objective of the paper is to present the method of production, quantity, and quality of obtained planting material per unit area of continental fruit within the period of three years (2018-2020), and, in particular, the nursery of raspberry variety Glen Ample in Polimlje, Bijelo Polje municipality, northern Montenegro. The paper shows the initial condition, preparation for the formation of nurseries, production, and quality of raspberry seedlings, which are among the most important berry fruit species grown in northern Montenegro. The production of nurseries was within the limits for the production of raspberry planting material. The number of plants per square metre (m2) at the end of the season was 20.2, and 202,000 per hectare (ha). The height of the seedlings at the end of the vegetation was 1.06 m, and the diameter above the root neck was 9.5 mm. The planting material met the prescribed standards. Based on the standard, seedlings were classified into three classes, and most seedlings of class I (73%) were obtained, followed by class II (24%), while only 3% of seedlings were out of class. Raising raspberry plantations with quality planting material is one of the most important factors for intensifying the production of this type of fruit in Montenegro.
