God skötsel av skyddszoner för effektivare växtnäringsretention

Our dependence on imported soy has recently become an issue. Faba beans may at least partly replace the soy. This is important for conventional as well as for organic production. The white-flowered cultivars are recommended for pig diets. The colour-flowered cultivars have better yields and …

Nightshade and hairy nightshade are two of the most serious weeds in row crops. Both species build up a persistent seed bank and thus require long-term control strategies. The aim of this project is to evaluate the effects of nightshade in an organic cropping system. In a crop rotation including …

The objective of this project is to develop new pea varieties with resistance towards root rot disease, in combination with excellent production properties. The disease is mainly caused by the oomycete Aphanomyces euteiches. Currently, neither pea varieties with resistance nor chemical pesticides …

We will investigate the use of barley cultivar of mixtures to reduce aphid attack. Our hypothesis is that cultivar mixing mobilizes the crop’s induced resistance, reducing aphid colonisation and population growth. The aim is to contribute to the development of a robust crop production system based …

Producers of broiler chickens are forced to report emissions of ammonia due to environmental considerations. By now no data regarding emissions of ammonia from modern Swedish broiler chicken houses are available. For field measurement there is a need for a simple method for quantification of these …

Clover is used in agriculture for fodder and green manure and today Sweden is world leading in producing organic clover seeds. However, the yield varies heavily between years and growers, partly because of damages by clover seed weevils. Effective suppression methods are entirely missing for …

The supply is limited and hte price is high. A feeding ration with only forage and cereal grain would be possible for on-farm production at most organic farms in Sweden. The model has been tested in short-term experiments covering the initial part of the lactation and results indicate lower milk …

Riding performance is influenced by the interplay between horse and rider and success is dependent on a good interaction. In an educational context this rider-horse dyad is complemented with a riding instructor/trainer. The study aims to describe and analyse the communication between rider and …

Mjölkkornas brunster blev svagare och kortare över de studerade sexton åren. Generellt så hade Svensk Röd boskap (SR), både i lösdrift och i uppbundet, högre andel lyckade dräktigheter samt starkare och längre brunster jämfört med Svenska Holstein (SH) kor. De första och mest upprepade …
