The successful introduction of new cultivars depends on the evaluation of complex parameters essential for the consumers, market, and fruit producers. A new scab-resistant apple cultivar, ‘Wuranda’ (SQ159/Natyra®/Magic Star® × Honeycrisp), recently introduced in Norway and managed under the name Fryd©, is prone to biennial bearing. Therefore, one of the first tasks, investigated in Southwestern Norway by the Norwegian Institute of Bioeconomy Research, NIBIO-Ullensvang in 2021–2024, was the establishment of optimal crop load level based on the combination of productivity, fruit quality, and return bloom. The apple cultivar Fryd (‘Wuranda’) was propagated on ‘M.9’ rootstock and planted in 2019. The trial was performed in the same orchard for four consecutive years, starting three years after planting. Crop load level affected average fruit mass but had no impact on cv. Fryd fruit quality parameters at harvest such as blush, ground color, firmness, soluble solid content, or starch degradation. Fruit size variation was diminished by crop load regulation, and most fruits fell into 2–3 grading classes. Crop load, not the yield per tree, was the determining factor for the return bloom. The optimal crop load level depended on the orchard age. To guarantee a regular bearing mode of cv. Fryd planted on M.9 rootstock at a 3.5 × 1 m distance and trained as slender spindle, crop load of 5.5–6 fruits cm−2 TCSA (trunk cross-sectional area) in the 3rd year, 7.5–8 fruits cm−2 TCSA in the 4th year, and 6.5–7 fruits cm−2 TCSA in the 5th year should be maintained.

Plant-based meat analogues (PBMA) are expected to reduce environmental, health, and animal welfare challenges from the production and consumption of meat. This paper investigates PBMA consumption using three rounds of a survey. PBMA consumption in Norway increased from 2017 to 2019 but stagnated in 2022. Several food choice motives and socioeconomic factors affected consumption consistently across the survey rounds. Emphasizing the environment, animal welfare, and novelty were positively associated with PBMA consumption, while emphasizing familiarity and Norwegian origin were negatively associated. Younger, higher educated, urban, and vegetarian respondents were more likely to consume PBMA. Use of social media had a positive effect on the consumption for the total sample, but it was not stable across the survey rounds. Producers, marketers, and other policy makers could promote the environmental and animal welfare benefits along with the novelty aspects of PBMA. The use of domestic ingredients could also appeal to older and rural individuals who emphasize food familiarity.

Purpose Losses of phosphorus (P) and carbon (C) from livestock farming impair downstream water quality, requiring a better understanding of their leaching processes. The aim of the study was to examine how leaching of P (total dissolved P – TDP; dissolved reactive P – DRP; dissolved organic P – DOP) and dissolved organic C (DOC) was affected by soil type, chemical property and amendment. Methods Leaching experiments with simulated rain were conducted on five different mineral and organic soils before and after a manure or mineral fertilizer application, respectively. The soils were: Fluvisol, Stagnosol, Umbrisol, Histosol (Ruptic), and Histosol. Profile-long soil columns were used, and chemistry of soil and water samples were studied. Results Before the P addition, the Histosol (Ruptic) soil with high P and organic matter contents but low sorption in the subsoil had significantly greatest flow-weighted mean concentrations (FWMCs) of TDP (315 versus 33‒48 µg L‒1), DRP (215 versus 5‒26 µg L‒1), DOP (101 versus 19‒33 µg L‒1) and DOC (46 versus 8‒25 mg L‒1) in drainage water among all soils. Leaching of DOC varied more than TDP, DRP and DOP across most soils. The manure application significantly elevated FWMCs-TDP in three soils than before the application and led to greater FWMCs-TDP in all soils and FWMCs-DOC in most soils than mineral fertilizer did. The ratios of DRP to DOP and to TDP were significantly correlated to whole-profile degree of P saturation (DPS) of the soils (R2 > 0.9, p < 0.05). Conclusion Sorption/desorption characteristics of subsoils greatly affected concentrations and loads of P and DOC in drainage, as well as the ratios of DRP to DOP and to TDP. Therefore, sorption/desorption characteristics and DPS of subsoils should be included in the work of assessing dissolved P and DOC leaching and developing nutrient mitigation measures.
