BACKGROUND There is widespread concern that the cultivation of oilseed rape leads to seasonal epidemics of respiratory symptoms in populations living in the neighbourhood, and it has been suggested that the plant is a potent allergen. A study was therefore undertaken to determine the prevalence of seasonal symptoms in rural populations close to and far from areas of oilseed rape cultivation, an...

The Verticillium genus comprises economically important plant pathogens that collectively affect a broad range of annual and perennial crops. Verticillium longisporum mainly infects brassicaceous hosts, including oilseed rape. The most conspicuous symptom of V. longisporum infection on oilseed rape is black stem striping that appears towards the end of the cropping season. Thus far, the impact ...

Following the extraction of oil for biodiesel production, oilseed press cakes are high in fat. As the dietary supplementation of fat is currently considered the most promising strategy of consistently depressing methanogenesis, it follows that oilseed press cakes may have a similar potential for CH4 abatement. As such, this study aimed to characterise the nutritive value of several oilseed pres...

Management of nitrogen fertilization in crops is one of the most important components of integrated weed management. A two-year field experiment was conducted to determine the direct effects of wild mustard aboveground biomass and N content of wild mustard on oilseed rape yield. A set of factorial treatments was arranged in a randomized complete block design with four replications. Treatments w...

In order to elucidate the effect of sowing date on oilseed rape (Brassica napus L.) yield and yield components, three varieties including Tower, Rafal and Global were sown from November 7 to December 22, 1998-99 in four dates with 15day intervals in Dezful region. A split-plot design based on randomized complete blocks with four replications was used in which levels of sowing dates and cultivar...

Winter oilseed rape was cultivated in monoculture or in combination with turnip rape as trap crop sown in trap strip. Preventative microbiological treatments for diseases control in winter oilseed rape were tested using Trichoderma asperellum and product based on effective microorganisms. Microorganisms were effective to protect of oilseed rape and allowed to obtain higher yield comparing to un...

As part of a project on adding value to farm operations with food-grade oils, the University of Vermont Extension and Pennsylvania State Extension teamed up to evaluate the design and operation of several small -scale oilseed presses. While there is a great deal of interest in the production of oilseeds, many questions arise about post-harvesting processing, and many of these concerns revolve a...

272 India accounts for 12-15% of world’s oilseed area, 7-8% of oilseeds output, 6-7% of vegetable oil production, 9-12% of vegetable oil import and 9-10% of vegetable oil consumption (Hegde, 2009). The country produces seven edible oilseed crops viz. groundnut, rapeseed-mustard, soybean, sunflower, sesame, safflower and niger and two non edible oilseeds viz. castor and linseed. Though the diver...

The crop species Brassica rapa L. has significant economic importance around the world. However, the global distribution and complex evolutionary history of the species has made investigating its genetic population structure difficult. Crop domestication and improvement has resulted in extreme phenotypic diversity and subspecies that are used for oilseed, food for human consumption, and fodder ...

Japan’s oilseed sector is divided into two main components: 1) a large oilseed-crushing industry that produces vegetable oil and oilseed meal, and 2) industries using oilseeds for food, without crushing them for oil. In general, the oilseed-crushing industry is protected by tariffs on vegetable oil at the border, but receives no domestic subsidies. Oilseed production for food, in contrast, gene...
