Este estudo teve como objectivo avaliar a influência de dois substratos na fitossanidade, na produção e na qualidade de morangos ‘San andreas’, produzidos em sistema hidropónico fechado “New Growing Systems”. O ensaio foi realizado na empresa Estufas do Vale, Lda, em Almeirim. Foi avaliada a fitossanidade, o pH e a condutividade eléctrica da solução drenada, a produção total e comercial e a qualidade dos frutos, através do peso médio por fruto, do calibre (diâmetro longitudinal e transversal) e do teor de sólidos solúveis totais. Os substratos não estavam isentos de agentes patogénicos, propag

Abstract:

Agriculture is one of the most carbon-intensive sectors in today’s world. With demand for food soaring to feed an ever-increasing population, many methods are employed to produce food, ranging from open-field to greenhouse systems. However, due to their large environmental footprint, urban agriculture methods such as soilless culture systems are increasingly becoming a preferred method for food production. A case study has been performed at Hollbium in Stockholm, Sweden for the purpose of evaluating potential environmental impacts of Hollbium Loop, a vertical hydroponic system used for food pr

Depois que a agricultura brasileira passou a ser destacada no cenário de das pesquisas científicas, o grande desafio passou a ser a padronização de produtividade em todo território nacional. Um dos principais focos vem sendo a região semi-árida pela sua escassez de água, tanto quantitativa quanto qualitativa, por ser uma região com baixo índice de precipitação e por suas águas subterrâneas normalmente serem águas salobras. Com este desafio nacional, vem se destacando a hidroponia em alguns Estados, pelo uso da água racionalmente. Com este aumento do uso da hidroponia vem aparecendo algumas dif

Abstract:

The many medicinal, nutritional, industrial, and agricultural uses of moringa are well documented, although studies remain focused on moringa as a wild, uncultivated plant and little horticultural research has been devoted to its culture. Greenhouse experiments were conducted at the State University of New York at Cobleskill, New York, USA during the summer of 2006. Soilless culture has been investigated as an alternative production system for medicinal and aromatic plants, and moringa seedlings were grown using hydroponic and aeroponic culture at a pH of 5.5-6.0 and electrical conductivity le

Abstract:

The configuration of the two leafy vegetables: lettuce (Lactuca sativa L.) and spiny chicory (Cichorium spinosum L.) was analyzed in a multi-factorial approach accounting for the effects of cultivars, salinity sources and number of cut. Under increasing level of NaCl in the nutrient solution the yield and growth of baby lettuce decreased with more detrimental effects on the green variety. However, the overall quality of baby lettuce increased at 20 mM NaCl whereas a significant decrease of the nutritional value was recorded at 30 mM NaCl.
