Abstract

Professional and scientific networks built around the production of sweet cherry (Prunus avium L.) led to the collection of phenology data for a wide range of cultivars grown in experimental sites characterized by highly contrasted climatic conditions. We present a dataset of flowering and maturity dates, recorded each year for one tree when available, or the average of several trees for each cultivar, over a period of 37 years (1978–2015). Such a dataset is extremely valuable for characterizing the phenological response to climate change, and the plasticity of the different cultivars’ behaviour under different environmental conditions. In addition, this dataset will support the development of predictive models for sweet cherry phenology exploitable at the continental scale, and will help anticipate breeding strategies in order to maintain and improve sweet cherry production in Europe.

Abstract

It is widely accepted that legume crops yield and basic chemical composition of pulses regarding crude proteins content are closely dependent on agro-environmental conditions and cropping system. Monoculture is used mostly in conventional agriculture, where the same crop is cultivated on the same land for a 12-month period. In an organic and integrated growing approach more attention is paid to plant-environment interactions, and as a result, diverse growing systems applying intercropping, catch crops, green manure, alternatives are being implemented. Thus, trials aimed at increasing the current knowledge on sustainable agriculture constitute an essential part of EUROLEGUME, which envisages the comparison of organic vs conventional cropping systems for faba bean and pea production in northern Europe. Thus, field experiments were set up in two different locations (AREI - Latvia and NIBIO -Norway). Results obtained showed significant differences in yield between tested genotypes of faba bean and pea. For pea most yielding cultivars (‘Klara’ and ‘Kirke’) slightly differed between trial locations, being the most promising in both locations. On the other hand, on faba bean accessions ‘Julia’ and ‘Lielplatones’ exhibited the highest yield in Norway, and ‘Bauska’ and ‘Lielpaltones’ in Latvia. Apart from the evaluation of the impact of crop rotation on legumes yield, the influence of legumes as intercrop with horticultural crops was also evaluated on a two years’ study, on vegetables and strawberry crops in Latvia. This work showed that the most efficient intercropping variants were cabbage/faba bean and carrot/faba bean, whilst onion and faba bean intercrop are not recommended.

Abstract

Quality aspects of food crops have been gaining increased attention at important regarding economic and health levels. Grain legumes have high potential for the nutritional improvement of foods, although to date, existing gaps of information on the compositional characteristics of legumes as feedstuffs and foodstuffs, as well as concerning technologies enabling the development of new food and feed products entail a reduced consumption. Recognizing this challenge, EUROLEGUME has addressed this topic by selecting the best legume varieties regarding their content in protein, amino acids, dry matter, ash, and total fats in a panel of underexplored varieties of faba bean (n = 10), pea (n = 16), and cowpea (n = 28). The results obtained on the proximate composition have identified nutritionally enhanced and genetically diverse germplasms. In this work it was identified the most promising genotypes of faba bean (‘Gloria’, ‘Džūkstes’, ‘Kučānes’, and ‘Aqua Dolce’), pea (‘Looming’, ‘k4171’, ‘k4831’,‘Eesti kollane söödahernes’, and ‘Bruno’), and cowpea (‘Vg50’, ‘Vg51’, ‘Vg56’, ‘Vg57’, ‘Vg58’, and ‘Vg59’) for the development of new attractive, convenient ready-to-eat, and tasty legume-based food formulations that will contribute to the diversification of healthier diets. In addition, in this work, significant differences were stated regarding the content in protein, total, essential, and non-essential amino acids between legumes grown in organic and conventional systems that allowed to highlight the relevance of the cropping system for the nutritional value of legumes.
