(Master thesis, 2014-11-04)Aphid (Aphis craccivora Koch) is an important cowpea (Vigna unguiculata L.) pest in Cuban agroecosystems, causing important damages. Aphid fluctuation in a cowpea crop was observed by weekly counting in a control treatment. ... -
Alternative food networks among farmers in Norway : a case study on the potential for expansion
(Master thesis, 2014-11-13)The industrialization of agriculture has lead many farmers into a situation of economic squeeze with increasing costs, falling income and high financial debt. In addition it has disconnected them from consumers. As a ... -
Quality analysis in winter wheat varieties grown in Norway: Investigating quality differences among winter wheat cultivars and impact of environmental factors
(Master thesis, 2014-12-11)Bread making quality is one the desirable goals to be met by wheat breeders and growers; however, this bread making quality is the determined by both genetic and environmental factors. Quality variation occurs in winter ... -
Support in defining specifications for the production of lamb on Alpine pasture in Isere (France)
(Master thesis, 2014-12-12)French mountain farming is mainly based on breeding systems and the use of semi-natural resources such as alpine pastures. Pastoralism provides many services that are not paid. It is therefore necessary to invent and ... -
Relationship between rhizome fragmentation, mowing and competition in control of common couch grass (Elymus repens)
(Master thesis, 2014-12-12)The perennial Elymus repens is considered to be one of the most important weeds on arable land in the Nordic countries. The 1st part of this thesis is principally a literature review on the species` biology and physiology ... -
Fusarium og Microdochium på såkorn - overlevelse ved lagring og betydning for spireevne
(Master thesis, 2015-02-24)I de senere årene har spiringsfusariose forårsaket av Fusarium- og Microdochium-sopper medført mangel på norskprodusert såkorn av god kvalitet, spesielt i havre. Det er derfor behov for mer kunnskap om betydning og overlevelse ... -
Fenologisk utvikling i rødkløver
(Master thesis, 2015-02-26)Rødkløver (Trifolium pratense) er en viktig plante i grovfôrproduksjonen i Norge. Det er nær sammenheng mellom fôrvekstenes fenologiske utviklingstrinn og deres fôrkvalitet. Både med tanke på praktisk dyrkingsveiledning ... -
Informed nudges : the effects of pre or post informing about motives and mechanisms of nudge based behavioral interventions
(Master thesis, 2015-02-26)Nudge based behavioral interventions are increasingly used to address emerging health challenges such as obesity, by helping individuals avoid known human psychological and behaviorally based biases and errors when exercising ... -
Effekt av jordtype og naboskap på blomstring i tidlig restaureringsfase
(Master thesis, 2015-02-26)Menneskeskapte endringer i landskapet og innføring av fremmede arter er noen av de mange miljøutfordringene vi har her i Norge. Et viktig skritt for å sikre det biologiske mangfoldet og økosystemprosesser nå og for ... -
Genetic variation in anther extrusion in oats and its relationship to Fusarium
(Master thesis, 2015-02-26)Anther extrusion (AE) is a trait that has been studied in wheat for its influence on Fusarium head blight. Fusarium is a disease causing great problems in Nordic small grain production, particularly in oat. However, AE ... -
Evaluating sustainable logistics for Local Food Systems and using colaboration as a tool for rationnalization in the retail-wholesale sector: A case study in the Nord-Pas de Calais region, France
(Master thesis, 2015-02-26)Localizing the organic food system is a key element for sustaining the development of organic agriculture globally. Local Food Systems (LFS) are often attributed to having advantages but their economic, ecological and ... -
Biology and control of the invasive Fallopia taxa
(Master thesis, 2015-05-07)Abstract Fallopia japonica and Fallopia sachalinensis are perennial, rhizomatous plants, native to East Asia, and introduced to Europe in the mid 1800’s. Hybridization between the taxa in the introduced range has given ... -
Green roofs for sustainable urban development : the Oslo case study
(Master thesis, 2015-05-12)Rapidly growing cities around the world face complex issues in sustainable urban development. In particular, urban ecological systems and food security are important in ensuring healthy, sustainable cities but they are ... -
Miljøeffekter av grønne tak og vegger
