… an increased intensity in the oil seed production can bring higher risk of yield losses due to fungal diseases. The purpose of this study was to investigate what different fungi are associated with oilseed rape under field conditions and if their incidence is correlated to crop …
… method. There was not a significant different between the methods. The net yield, including chipping and forwarding was included was 5303 SEK per ha for the energy wood system and -518 SEK per ha for the pulpwood system.

… 1994, Holgen m.fl. 2000). However it is also necessary that the methods will yield a reasonable economic return (Lindén & Ekö 2002). It is therefore of great importance to study alternative silvicultural methods (Cedergren 2008). In the eastern part of the county of Blekinge in …
hur påverkas lantbruksföretagens ekonomi och produktionsinriktning?
… effects of preceding crops, relationships between nitrogen application, yield and important quality parameters such as protein content in grain. Since the reduction of greenhouse gas emissions is not determined in quantity or formation, the results are presented according to two …
… by grazing. This saves both money and time. According to research milk yield decrease with an increasing proportion of pasture in the diet. This is because cows on pasture will have lower dry matter intake than cows with supplements. On a pasture-only diet, high producing cows …
… calculated using an average life time and 6 % interest rate and annual milk yield is 9 500 kg/cow and year. Structure effect 3-4 % higher for an insulated structure than in an uninsulated for 400 and 120 herd respectively. This is much lower compared to what is normally argued …
… be seriously infested with hard fungus attack. Since it is important that the yield bears a high quality it is of great importance to find varieties more resistant to attacks.Pathogenesis-related (PR) proteins are stress proteins induced in the plant in response to infection and …

… is shown, how it can save water and energy; how this method can improve crop yield by supplying the right amount of water at the right time. It is shown how irrigation scheduling and irri-gation technology together increase the irrigation efficiency.
… which employ acoustics to monitor rumination duration. The time budget of high yielding cows was studied and possible differences in rumination time between 13 rations were interpreted. Further the study examined what affects daily rumination and rumination efficiency. The …
… was calculated from the ambient temperature and relative humidity. The milk yield was measured at each milking and when the temperature outside was high, milk samples were taken to measure the components and the somatic cell count of the milk. Grass samples were also taken to …
… in China has decided to create 5.8 million hectare of fast growing and high yield forest. Eucalyptus has showed to have good properties for pulp and timber production and therefore Eucalyptus plantations are under development in costal areas in southern China. By adding extra …
… service mission. The consequence due to that mission is that they have limited yield potential but on the other hand the right to certain subsidies. They are also limited by the law of public purchasing (in Swedish: Lag om offentlig upphandling) in the investment process. A …
