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. ... -
Organization of farmer groups impacts farmer experimentation and learning for agroecological practices : evidence from Southeast France
(Master thesis, 2017)There is wide agreement that sustainable practices in agriculture are needed in order to meet the future needs of a growing population on a planet in environmental crisis. Agroecological practices can help with this daunting ... -
Palm oil production in Peruvian Amazon Basin. A case study of current effects and emerging localized alternatives in Loreto district
(Master thesis, 2015-08-06)An analysis of palm oil production in the Peruvian Amazon basin was carried out in a systemic way, as part of a whole, with its complexities. With an agroecological perspective, the social, ecological and economic effects ... -
Participatory video in agroecology education : a multiple-case study with the Green Learning Network
(Master thesis, 2016-11-22)A transformation of our food system necessitates a revision of how we think and communicate about agriculture. In the past few decades, increasing attention has been paid to the unique requirements of teaching sustainable ... -
Pepinomosaikkvirus - overlevelse under kompostlignende forhold
(Master thesis, 2021)Bruken av kompostert plantemateriale som en komponent i vekstmedier og til jordforbedring kan medføre et potensiale for spredning av plantepatogener. Kunnskap om patogeners respons på ulike komposteringsforhold er nødvendig ... -
Phenology and effect of climate on apple cultivars (Malus Domestica Borkh.) in Norway
(Master thesis, 2015-07-16)Successful fruit growing is dependent on a good control of flower-bud formation (FBF), knowledge on the timing of developmental processes in the tree, and how these are related to each other in the Norwegian climate and ... -
Phenotypic and genotypic variation in the allopolyploid Arabidopsis suecica and its parent species A. thaliana and A. arenosa : an investigation of a possible model for studies of polyploidy and invasiveness
(Master thesis, 2014-09-26)Species that possess more than two sets of chromosomes are denoted as polyploids. It is hypothesized that polyploids show high gene redundancy, hybrid vigour and masking of deleterious alleles, and that this make them ... -
Phenotypic characterization and ploidy level determination of perennial ryegrass (Lolium perenne L.) gene bank accessions and cultivars
(Master thesis, 2020)Perennial ryegrass (Lolium perenne L.) is the most grown perennial grass species all over the world, because of the rapid regrowth and good nutritional composition. Winter survival is challenging when growing perennial ... -
'Pioneer Farmers' : joint exploration of crop diversity and agroecosystem function in Walsala, Nicaragua
(Master thesis, 2016-09-06)Exploring the role of crop diversity on the functioning of agroecosystems has significant implications for agriculture. ‘Pioneer farmers’, on Nicaragua’s agricultural frontier are adapting their cropping systems to new ... -
Pollen chemical composition determined by infrared spectroscopy : species identification and environmental effects.
(Master thesis, 2014-10-23)In this study pollen is collected from different populations of common and widespread plants in alpine and lowland habitats. Infrared spectroscopy was used to determine chemical composition of pollen. Although this is a ... -
Pollinator trees as a potential inoculum sources for fruit decay fungi on apple
(Master thesis, 2018)Over the recent years it has become common to plant cultivars of crab apple as pollinators at regular distance in the rows of the apple fields. Little or no specific knowledge exist about the susceptibility to diseases of ... -
Potential of the green dock beetle (Gastrophysa viridula) as a biocontrol agent of northern dock (Rumex longifolius) in Norwegian grassland
(Master thesis, 2020)Docks (Rumex spp.) act as weeds in many parts of the world, and in Norwegian grasslands, the northern dock (Rumex longifolius) is the most widespread dock species. The ability of farmers to control docks without the use ... -
