Using potted sugar beet plants we aimed to investigate the suitability of four fluorescence indices to detect and differentiate the impact of nitrogen supply, water deficit and powdery mildew in two sugar beet cultivars (<i>Beta vulgaris</i> L.). Plants were grown inside a polytunnel under two nitrogen...

In this study, we investigated the effects of different feed structures and beddings on the spread of <i>C. jejuni</i> in broiler flocks, and the effect on the cecal microbiota. Broiler chickens raised in 24 eight-bird group cages on either rubber mat or wood shavings were fed either a wheat-based...

Taro leaf blight (caused by the Oomycete <em>Phytophthora colocasiae</em>) is a disease of major importance in many regions of the world where taro is grown. Serious outbreaks of taro leaf blight in Samoa in 1993 and in the last few years in Cameroon, Ghana and Nigeria continue to demonstrate the...

With increasing economic and environmental costs associated with fertilizer use, the need for low-input agroecological systems is on the rise. It is well documented that intercropping legumes can increase the supply of nutrients, through N<sub>2</sub>-fixation and P mobilization. Concurrently, the...
