Strategies to increase prebiotic activity and neurotrophic potential through di...
Silva, Soraia P.; Gonzalez, Abigail; Roupar, Dalila; Salvador, Andreia Filipa Ferreira; Bastos, Rita; Mota, Mariana; Luís, Maria H.; Ferreira, Sónia S.Soluble polysaccharides and oligosaccharides are prebiotic compounds that promote the growth of beneficial gut bacteria and contribute to improved health. Industrial juice production results in juices with moderate amounts of soluble dietary fibre because most polysaccharides that constitute the dietary fibre are retained in the pulp. Incorporation of glucanases and pectinases into the juice production process ...
Partial replacement of mineral fertilisers with animal manures in an apple orch...
Esteves, Catarina; Costa, Eva; Mata, Miguel; Mota, Mariana; Ribeiro, Henrique; Fangueiro, DavidPartial replacement of mineral fertilisers (MF) with animal manures is a good alternative to reduce MF use and increase both nutrient cycling in agriculture and soil organic matter. However, the adoption of this practice must not lead to increased environmental impacts. In this two-year study conducted in an apple orchard, MF were partially replaced with various animal manures, including cattle slurry (CS), aci...
Water requirements and crop coefficients of edible, spicy and medicinal herbs a...
Pereira, Luis S.; Mota, Mariana; Raziei, Tayeb; Paredes, PaulaTraditional edible, spicy and medicinal herbs rarely are included in studies on water requirements, evapotranspiration and crop coefficients (Kc) of vegetable crops. While the latter refer to large markets and are used worldwide, the former has small and specialized markets. They are very rarely grown in large farms but rather in small farming systems, or just harvested in the wild, and related evapotranspirati...
Analysis of Petiole Sap Nutrients Using Rapid and Standard Methods and Its Rela...
Mota, Mariana; Martins, M.; Sprey, Layanne; Maurício, Anabela; Rosa, Cristina; Faria, João; Martins, Miguel; Sousa, Miguel L. de; Santos, RicardoCurrently, fertilization decisions in apple orchards are based on soil and leaf analyses while the leaf material is sampled after the growing season, usually in June–July (90–110 days after full bloom). This approach is inefficient, as the information becomes available later than the growing season and is therefore only useful in supporting fertilization decisions for the next year, not the current one. To esta...
ProtecEstenfilio - Estudar a evolução da estenfiliose na cultura da pereira 'Ro...
Rego, Cecilia; Luz, João Pedro; Azevedo, João; Dias, António; Garcia, Ana; Cabanas, Andrea; Oliveira, Cristina; Mota, Mariana; Francisco, CatarinaEste projecto compreende 3 actividades principais: a) Avaliação do status quo do pomar e a incidência de estenfiliose. A avaliação das práticas culturais efetuadas pelos diferentes produtores nos últimos 5 anos, com recurso a inquéritos, a avaliação da flora existente nos pomares e o acompanhamento dos pomares durante o período de execução do projeto contribuirá para se estabelecerem possíveis relações entre as...
Partial replacement of chemical fertilizers with animal manures in an apple orc...
Esteves, Catarina; Fangueiro, David; Mota, Mariana; Martins, Miguel; Braga, Ricardo P.The combined use of chemical fertilisers with organic materials in crop fertilization is an essential approach to transition towards a more sustainable and resilient agriculture in Europe. In an apple orchard, chemical fertilisers (CF) were partially (25 to 57%) replaced with animal manure (cattle slurry - CS, acidified cattle slurry - ACS, cattle solid manure - CsM, and poultry manure - PM), based on the crop’...
Improving chestnut physicochemical properties through fermentation – Developmen...
Santos, Marisa V.; Banfi, Stefano; Santos, Rafaela; Mota, Mariana; Raymundo, Anabela; Prista, CatarinaThe increased awareness of population regarding the impact of consumption habits is leading to interest in new, innovative, diversified and health promoting foods. In this work, two new amazake fermented products were developed with chestnut (Castanea sativa Mill.), using rice or chestnut koji as source of glycolytic enzymes. The analysis of the amazakes evolution showed improvements in chestnuts physicochemica...
Evaluation of the fertilizer potential of Chlorella vulgaris and Scenedesmus ob...
Alvarenga, Paula; Martins, Marta; Ribeiro, Henrique; Mota, Mariana; Guerra, Inês; Cardoso, Helena; Silva, Joana LaranjeiraProducing microalgae with agricultural drainage water (ADW) allows recycling water and nutrients, with the production of a biofertilizer, avoiding receiving waters' contamination. Chlorella vulgaris and Scenedesmus obliquus were cultivated using ADW and standard media supplementation and presented higher productivities, relatively to the control industrial growth medium (using freshwater). Selected strains were...
Nutrient Content with Different Fertilizer Management and Influence on Yield an...
Mota, Mariana; Martins, Maria João; Policarpo, Gonçalo; Sprey, Layanne; Pestaneira, Mafalda; Almeida, Patrícia; Maurício, Anabela; Rosa, CristinaAssessing a plant’s nutritional status and fertilizer rates and types that can optimize fruit quality and yield are critical in intensive apple orchards. The aim of this work was to identify correlations between nutrients in the different organs that allow the early diagnosis of the nutritional status and to assess the impact on the optimal nutrient content in apple leaves, as well as in the yield and quality o...
Improving nutritional quality of unripe tomato through fermentation by a consor...
Simões, Sara; Santos, Rafaela; Bento-Silva, Andreia; Santos, Marisa V.; Mota, Mariana; Duarte, Noélia; Sousa, Isabel; Raymundo, AnabelaBACKGROUND: Portugal is one of the main producers of industrial tomato and tomato paste, an important intermediate ingredient used in many added-value foods. The tomato processing industry rigorously selects the fruits by colour during mechanical harvest, picking only completely ripe fruits to produce high quality tomato paste. The latest available data shows that about 1.12 × 108 kg yr−1 of non-red/not-ripe to...
