In this paper, we investigated the effect of water stress caused by partial rootzone drying (PRD) on raspberry canes. Our study was conducted in Kosovo during 2015-2016 in a one- to two-year-old raspberry plot using a nested experimental design. The aim was to assess different levels of irrigation on vegetative and productive parameters. Four levels of budget irritation were studied: 100% ET (control) lateral, two laterals (TL), side lateral (SL), and without irrigation (WI). Each treatment contained 5 plants. Using ANOVA we found that irrigation caused significant changes on the number of leaves, leaf surface and area, LAI, shoot length, number of fruit, fruit weight, total yield, fruit diameter and fruit length. For all elements, the lowest values were found in treatment without irrigation so in our climatic conditions raspberry cultivation cannot be performed without irrigation. With the PRD, the canes showed a reduction in vegetative growth. Application of partial rootzone drying, respectively, four different levels of irrigation in raspberry is a novelty (innovation), and each result will contribute to the knowledge of this crop and PRD.
