“…In this sense, Salvo et al (2011) found that the number of fruits per bud depends significantly on the variety and age of the plant. In addition, Palma et al (2023) indicated that the number of flower buds per cane showed a positive relationship with cane diameter and cane age. These authors also claimed that as blueberry bushes need regular pruning to establish and maintain a balance between the vegetative and reproductive parts of the plant, pruning practices are determinant on fruit yield and quality.…”

LCA methodology provides the best framework to evaluate environmental impacts in agriculture systems. However, the interpretation of LCA results, in particular when the objective was to compare different production systems, could be affected by the selection of the functional unit (FU). That is why an accurate definition of the FU, in agreement with the function considered for the systems analysed, is essential. In this work, the organic production at small scale of blueberry, raspberry, blackberry and cape gooseberry in North Spain has been analysed following LCA methodology. Although a different distribution of environmental loads was obtained for each crop, in all cases, the main contributions to most of the considered environmental categories were electric and fertiliser consumptions. The different production systems have been compared on the basis of the environmental impacts associated considering different FUs, i.e. based on fruit mass, cultivated area, farm-gate price and nutritional quality of fruits. Carbon footprints (CF) have been also calculated. It was observed that the order of the crops with respect to their environmental performances was the same for the blueberry and raspberry crops (with the lowest and the highest CF, respectively), independently of the selected FU, whereas the order of the blackberry and cape gooseberry crops was interchanged, depending on the FU used. This work supports the need of being aware of the final objective of the orchards when choosing the FU (i.e. producing fruits, cultivating an area, economic benefits or nourishing people), so that valid conclusions can be achieved from the environmental comparison, even for different agricultural products.

In this study, we address the question of the most important factors influencing yield and fruit quality in highbush blueberries. An experiment was carried out to investigate the relationship between yield components and (i) plant yield, (ii) fruit quality traits, and (iii) fruit firmness post-harvest in two Vaccinium corymbosum L. blueberry cultivars (‘Duke’ and ‘Brigitta’). In a field in central Chile (35°15′39″ S; 71°14′32″ W) during the growing season 2018–2019, we measured the number of canes (NC), length of the first shoot (LFS), age of the first shoot (AFS), diameter of the first shoot (DFS), flower buds per cane (FBC), number of one-year shoots per cane (SPC), flowers per bud (FPB), fruit set percentage (FSP), yield (YLD), fruit weight (FW), fruit firmness at harvest (FF), fruit diameter at harvest (FD), soluble solids/acid ratio at harvest (SS:AC), and fruit firmness after harvest (FFpos). The most important factors affecting yield and fruit quality were FBC, SPC, and FF. Our results suggest that FBC and SPC could be managed agronomically to optimize fruit load and light interception.
