Sustainable water management in horticulture: Problems, premises, and promises
Ferreira, Carla; Soares, Pedro R.; Guilherme, Rosa; Vitali, Giuliano; Boulet, Anne; Harrison, Matthew Tom; Malamiri, Hamid; Duarte, A.C.Water is crucial for enduring horticultural productivity, but high water-use requirements and declining water supplies with the changing climate challenge economic viability, environmental sustainability, and social justice. While the scholarly literature pertaining to water management in horticulture abounds, knowledge of practices and technologies that optimize water use is scarce. Here, we review the scienti...

Soil macrofauna under laying hens’ grazed fields in two different agroecosystem...
Soares, Pedro R.; Guilherme, Rosa; Conceição, Antónia; Galhano, CristinaAlthough chickens can improve the chemical properties of soil through the deposition of excreta, their effects on soil macrofauna are poorly known. This work assessed the effects of grazing indigenous laying hens on soil macrofauna of two agroecosystems in Portugal: an organic horticultural field and a conventional orchard. At the horticultural field, laying hens were used to control weeds and the results were ...
Sweet peppers discrimination according to agronomic production mode and maturat...
Guilherme, Rosa; Rodrigues, Nuno; Marx, Ítala; Dias, L.G.; Veloso, Ana C.A.; Ramos, Ana Cristina; Peres, António M.; Pereira, J.A.The demand for organic foods has increased worldwide, in particular due to the association with healthier, more nutritious and tasty products, being a clear trend on sweet peppers’ consumption. Thus, this study aimed to evaluate the effects of agronomic production mode (conventional and organic) and maturation stage (associated to green, turning and red colours) on the chemical-sensory attributes of peppers gro...
Phenolics and antioxidant activity of green and red sweet peppers from organic ...
Guilherme, Rosa; Aires, Alfredo; Rodrigues, Nuno; Peres, António M.; Pereira, J.A.Today, consumers are very concerned regarding food quality, nutritional composition and positive health effects of consumed foods. In this context, the preference and consumption of organic products has been increasing worldwide.

Controlo de infestantes em Horticultura em modo de produção biológico.
Guilherme, Rosa; Baptista, Paula; Reboredo, Fernando; Pereira, J.A.Na produção de hortícolas em modo de produção biológico (MPB), o controlo das plantas infestantes é de grande dificuldade, limitando a produção devido à competição que exercem pela água e nutrientes. Neste sistema de produção a minimização dos prejuízos causados pelas infestantes, é conseguida normalmente pelo recurso a métodos culturais, físicos e mecânicos, onde é impedida a germinação, limitado o seu desenvo...
