Abstract
Sweet cherries are grown in areas with suitable local climatic conditions up to 60°N in Norway. All orchards have high density planting systems and are rain covered. The most common system now is multibay high tunnels systems where the trees are under plastic cover from the bloom to the end of the harvest. All orchards are fertigated and the production is aimed to supply the fresh fruit domestic market with high quality fruit from early July and to the end of August. At NIBIO Ullensvang, western Norway a large number of sweet cherry cultivars and advanced selections from worldwide breeding programmes have been evaluated continuously since 1959 and several cultivars have been recommended from this programme for commercial production during the last decades. During the last six years approximately fifty cultivars and advanced selections grafted on the rootstock Gisela 6 have been tested. Important objectives were to obtain large and precocious yields, with important quality parameters like fruit size, fruit firmness, soluble solids, fresh appearance, good flavour and resistance against irrigation induced cracking. Based on the results from the recent testing program, the following cultivars are currently recommended for the fresh fruit market: a) for early season: ‘Adelka’, ‘Pacific Red’, ‘Sweet Aryana’ and ‘Bellise’, b) for mid-season: ‘Brooks’, ‘Giant Red’, ‘Grace Star’ and ‘Folfer’ c) for late season: ‘Van’, ,’SPC 342’, ‘LaLa Star’, Royal Edie’, ‘Tamara’ ‘Lapins’, ‘Royal Helen’, ‘Regina’ and ‘Sweetheart’.

Abstract
Since the 1950s, the use of plastics in agriculture has helped solving many challenges related to food production, while its persistence and mismanagement has led to the plastic pollution we face today. A variety of biodegradable plastic products have thus been marketed, with the aim to solve plastic pollution through complete degradation after use. But the environmental conditions for rapid and complete degradation are not necessarily fulfilled, and the possibility that biodegradable plastics may also contribute to plastic pollution must be evaluated. A two-year field experiment with biodegradable mulches (BDMs) based on polybutylene adipate terephthalate (PBAT/starch and PBAT/polylactic acid) buried in several agricultural soils in mesh bags showed that also under colder climatic conditions does degradation occur, involving fragmentation after two months and depolymerization by hydrolysis, as shown by Fourier-transform infrared spectroscopy. The phytopathogenic fungus Rhizoctonia solani was found to be associated with BDM degradation, and the formation of biodegradable microplastics was observed throughout the experimental period. Between 52 and 93 % of the original BDM mass was recovered after two years, suggesting that accumulation is likely to happen in cold climatic regions when BDM is repeatedly used every year. Mass loss followed negative quadratic functions, implying increasing mass loss rates over time. Despite the range of climatic and edaphic factors, with various agricultural practices and vegetable productions at the study locations, the parameters that significantly favored in situ BDM degradation were higher soil organic matter content and temperatures.
