This study was conducted at the Agricultural Research Station, Hada El-Sham, King Abdulaziz University during 2006 and 2007 seasons. Four canola varieties, Callypso, Pactole, Sero-4 and Sero-6 varieties were tested under four nitrogen fertilizer rates (0.00, 92,138 and 184 kg N/ha) to determine the effect of nitrogen fertilizer on the canola (Brassica napus L.) seed yield, yield components and ...

Cold-pressed canola cake is a coproduct of biodiesel production that contains more residual oil than expeller-pressed and solvent-extracted canola meal. Cold-pressed canola cake might be an attractive feedstuff for swine due to local availability from small plants. However, the nutritional quality and content of anti-nutritional factors of cold-pressed canola cake are poorly defined and vary wi...

Effect of salinity on pollen viability, germination and yield was investigated on 8 canola cvs. Dunkled, Canola-III, Oscar, Ganyou-5, Ganyou-2, Rainbow, Abasin-95 and Westar. Plants were irrigated with non saline, 0.2% (E.C 2.5 dS.m). 0.4% (E.C 4.5 dS.m) and 0.6% (6.5 dS.m) of sea salt concentrations. Plant growth on vegetative as well as reproductive phases was proportionately inhibited with r...

Direct seeded canola (Brassica napus L.) has become increasingly popular in China’s key canola-producing regions. The studies on the K response of direct-seeded performance are limited. This research aimed to investigate utilization efficiency and canopy radiation interception rate direct winter at various application rates. Two seasons field trials were done with five levels (0, 75, 150, 225...

Adequate nutrition is essential for crop growth, production, and profit potential farmers, but chemical fertilizer costs alone can constitute a greater portion of the total variable wheat canola. The present study evaluated seven cropping treatments (CT) in 3-year rotation under two different soil types. Five CTs consisted one-time application (year 1) beef cattle manure, growing cover cocktail...

Seed germination, seedling emergence and crop establishment are important aspects of canola production, and are the main components of seed/seedling vigour. A major concern of seed businesses and canola growers alike is loss of seed vigour that may go undetected before planting. Two vigour assays, based on off-gassing of ethyl alcohol from poor vigour seed, are being developed. They are a simpl...

The fungal pathogen Sclerotinia sclerotiorum (Lib.) de Bary is worldwide in distribution and pathogenic to more than 400 plant species. This disease causes significant yield losses of various important crops including sunflower, canola, and soybean. Applying fungicides and crop rotation are currently the major methods of controlling this disease. However, fungicide chemicals are expensive, not ...

Genomics is revolutionising the speed with which biological information can be accumulated thanks to the use of high throughput molecular and bioinformatics technologies. The complete DNA sequencing of the Arabidopsis genome is helping plant biologists to unravel the remarkable “machinery” of how plants grow and develop. This article describes a genomic research project focusing on the study of...

Canola meal is derived from the crushing of canola seed for oil extraction. Although it has been used in swine diets for a long time, its inclusion levels have been limited due to concerns regarding its nutritive value primarily arising from results of early studies showing negative effects of dietary canola meal inclusion in swine diets. Such effects were attributable to the presence of anti-n...
