Multitrophic effects of the relationship between a plant growth-promoting rhizobacteria (Bacillus amyloliquefaciens) and arugula (Eruca sativa) on the predator Doru luteipes, using Plutella xlyostella and Spodoptera frugiperda
(Master thesis, 2018)Background. Plant growth-promoting rhizobacteria (PGPR) provide several benefits to plants, such as faster growth, larger yields and resistance to pests. When attacked by herbivores, plants defend themselves in various ... -
Fornying av eng ved direktesåing : effekten av tettleik i svoren på etableringssuksess
(Master thesis, 2019)Med direktesåing kan ein fornya plantedekket med lågare kostnadar og meir miljøvennleg enn ein full fornying med pløying. Men å få til ei vellukka etablering viser seg å vera utfordrande. I fleire forsøk som har blitt gjort ... -
Organisk avfall som vekstmedium og næring for solbær (Ribes nigrum L.) på intensivt grønt tak og sosiale effekter av urbant landbruk
(Master thesis, 2018)Til urban dyrking i bykjernen er det vanlig å kjøpe jord siden jorda i byen ofte er forurenset. En sirkulær økonomi, med fokus på avfallshåndtering, er derfor en forutsetning for at urban dyrking skal være bærekraftig. ... -
Modulation of selected inflammatory responses and non-specific defenses in Atlantic salmon induced by beta-1,3/1,6-glucans (Macrogard®)
(Master thesis, 2018)The anadromous nature and long production cycle of Atlantic salmon (Salmo salar L) demands for vaccination regimes to maintain long-term protective immunity in vaccinated fish. While prime vaccination is largely based on ... -
Investigation of the physiological basis of yield differences in Norwegian spring wheat
(Master thesis, 2018)Norway has a total land area of 324,000 km2 of which only 3% is arable. Moreover, the climate conditions allow a short growing season for agriculture. Despite these challenges, Government policies are directed towards ... -
Towards increased use of IPM : an investigation of Norwegian grain farmers' pest management practices and decision processes
(Master thesis, 2018)The last decade, Integrated Pest Management (IPM) has become mandatory in many European countries, but implementation on farm level is lagging and evidence for the barriers and driving forces is lacking. The goal of this ... -
Effects of temperature on dehydrin expression in mature somatic embryos of Norway spruce (Picea abies)
(Master thesis, 2018)Abstract: This master thesis deals with genetic and epigenetic effects in two genotypes (denoted A2K and B10) of in vitro derived somatic embryos (SEs) of Norway spruce (Picea abies (L.) Karst at different temperature ... -
The experience of members of European CSAs
(Master thesis, 2018)Community Supported Agriculture (CSA) is an alternative food system that directly connects consumers with producers. Though in theory CSA ameliorates some of the negative environmental, social, and economic impacts of ... -
Co-developing a cereal network in Pajottenland, Belgium : a participatory action research to empower farmers within a region
(Master thesis, 2018)In Belgium only 15% of wheat for human consumption and less than 4% of barley used by national breweries are grown on Belgian territory. In order to overcome this shortage, farmers and processors joined hands in the region ... -
Assessment of agroecological development : a case study of the Allgäu region
(Master thesis, 2018)The framework of agroecology territories suggests that transitioning to sustainable agriculture and food systems is most efficient on a territorial scale. To understand the processes and show positive outcomes of agroecological ... -
Drivers and barriers for the agroecological transition of the French Polynesian farming systems : case study on crop farmers
(Master thesis, 2018)In recent years, the quality of French Polynesian agricultural production has been increasingly criticised by consumers, who are concerned about pesticide residues in vegetables. Parallel to that, farmers are accused of ... -
Decentralization and liberalization of seeds and plant genetic resources regulations in Europe : a Danish case study
(Master thesis, 2018)In a context of severe plant genetic diversity erosion, the regulatory framework of the European Union is perceived as a limiting factor for practices aiming to conserve cultivated biodiversity. To create more supportive ... -
Conservation and regulation of key photoperiod regulators in the Pooideae subfamily of grasses
(Master thesis, 2018)Plants have adapted to seasonal constraints of the temperate environment by exploiting annual fluctuations in day length. Well timed flowering is essential to maximize reproductive output in temperate regions with short ... -
Harnessing indigenous knowledge and endogenous potential for peasant-led rural development : a case study in Jika village, Sichuan, China
(Master thesis, 2018)In an economy where the chasm between rural and urban life widens further each day, many Chinese farmers still struggle to maintain ecologically sound farming systems that can also support socially and financially robust ... -
Do insect fungivores that visit polypore cafes aid sporedispersal?
(Master thesis, 2018)Dispersal of wood-decaying fungi has been well studied, but the importance of insects for the dispersal of spores are less documented In this study I sampled beetles from red belt conk, tinder fungus and aspen bracket by ... -
CombCut : selective control of docks (Rumex spp.) in grassland
(Master thesis, 2018)Rumex spp. are known as troublesome weed species in grassland, both in pastures and on arable land, reducing both grass yield and forage quality. A novel machine called CombCut (Just Common Sense AB) has been designed to ... -
Utilizing shared segments for build-up genomic relationship between the Norwegian and the Swedish Fjord Horse
(Master thesis, 2018)Challenges in conservation of native breeds, like the Norwegian Fjord Horse, require an evaluation of the relationship between animals in different countries. Traditionally pedigree data have been used to calculate ... -
Influence of compost, vermicompost and digestate on nutrient status and secondary metabolites, Lactuca sativa L. as a model
(Master thesis, 2018)Peat is the most commonly used substrate in greenhouse cultures due to its predictability and performance. Though significant environmental costs and CO2 emissions are associated with harvesting of peat. It is therefore ... -
QTL analysis of pre-harvest sprouting resistance in SHA3/CBRD x Naxos spring wheat population under different environmental conditions
(Master thesis, 2018)Pre harvest sprouting (PHS) in wheat refers to an untimely germination of mature kernels within the spikes before harvest while still in the mother plant. This is the single most important factor for quality-degradation ...
