Influência da consociação com diferentes trevos, da rega e da variedade na prod...
Lourenço, Maria Ermelinda V.L.; Palma, Paulo M.M.; Massa, Vitor M.L.; Silva, Luis LeopoldoHavendo alguma evidência de que as leguminosas podem beneficiar as gramíneas pela transferência de azoto fixado seria de todo o interesse utilizar consociações em vez de azevém em estreme fertilizado com azoto. Como conclusões gerais, podemos referir que a utilização do trevo squarroso, em consociação com o azevém anual, se mostrou vantajosa, comparativamente aos outros trevos, pois mostrou tendência para apres...
Chickpea genotype adaptation to Mediterranean Environment
Simões, Nuno; Duarte, Isabel M.; Silva, Luis Leopoldo; Lourenço, Maria Ermelinda V.L.; Chaves, Manuela M.Genotypes that fasten their development cycle showed higher grain yield. Earlier start of flowering means higher soil water availability and lower maximum temperatures (middle of April), allowing to set more flowers and pods per plant and consequently higher grain yield. End of flowering started on May 19 in earlier genotypes. On this date the most hydrated genotypes are the ones with the longest growth cycle...
Screening chickpea resistance to water deficits: the yield perspective.
Duarte, Isabel M.; Silva, Luis Leopoldo; Simões, Nuno; Imtiaz, M.; Pinheiro, Carla; Lourenço, Maria Ermelinda V.L.; Chaves, Maria ManuelaScreening a wide range of germplasm from our major crops (including legumes) to search for genetic variation of traits involved in stress resistance is extremely relevant in the context of predicted increase in aridity in several areas of the world, including the Mediterranean (1,2). On the other hand, the keystone of ‘crop drought resistance’ relies on the effective use by the crop of a limiting water supply (...
Annual ryegrass yields under supplemental irrigation
Lourenço, Maria Ermelinda V.L.; Palma, Paulo M.M.; Silva, Luis Leopoldo; Massa, Vitor M.L.two-year field trial was conducted to evaluate the effect of supplemental irrigation on increasing and stabilizing yield and quality of forage produced by annual ryegrass in southern Portugal. The following four irrigation treatments were tested: rainfed (control), and irrigation up to 25%,50% and 100% of soil water holding capacity. In both years, the importance of irrigation was evident in order to increase a...
Influence of supplemental irrigation on annual ryegrass in southern Portugal
Lourenço, Maria Ermelinda V.L.; Palma, Paulo M.M.; Silva, Luis Leopoldo; Orvalho, HugoThe objective of this research was to evaluate the effect of supplemental irrigation on increasing and stabilizing yield and quality of forage produced by annual ryegrass in Southern Portugal. The following four irrigation treatments were tested: rainfed (control), and irrigation up to 25%, 50% and 100% of soil water holding capacity. The results showed that irrigation doubled the number of harvests, four inste...
