A 2-yr field trial (2001 and 2002) and 1-yr semifield trial (2002) were conducted to evaluate the effect of transgenic herbicide (glyphosate) -tolerant canola Brassica napus L. pollen on larval and adult honey bee, Apis mellifera L., workers. In the field trial, colonies of honey bees were moved to transgenic or nontransgenic canola fields (each at least 40 hectares) during bloom and then sampl...

Soil salinity is one of the major abiotic stresses that adversely affect plant productivity and quality. Therefore, an experiment was conducted to investigate the effects of seed treatment with L-arginine on some morphological and physiological parameters of Brassica napus under salinity stress. The seeds of canola were pre-treated with three arginine concentrations (0, 5, and 10µM Arg) for 24 ...

Canola yield production is driven by the balance between source (leaves) and sink (pods seeds) activity during reproductive period of a crop. However, previous literature has not reported impact source-sink limitations under different nitrogen (N) supplies, its effect on seed filling. Therefore, objectives this study were to 1) explore manipulations filling main parameters: duration rate; 2) un...

True ileal lysine digestibilities were determined using the homoarginine (HA) method in casein-, barley-, canola meal-, and barley-canola meal-based diets fed to growing pigs. Four Yorkshire barrows (25 to 49 kg BW) equipped with ileal T-cannulas were fed one of the diets according to a 4 x 4 Latin square design. All diets, except for the barley diet, were formulated to be similar in DE:CP rati...

Elemental sulfur (ES) fertilizers have high S content but may not be effective in the year of application due to time required oxidize. Rapid oxidation possible if ES has a large surface area contact with soil. We evaluated efficacy Sulgro 70, micronized fertilizer that is sprayed onto soil surface, eight field trials southern and central Alberta over 2 yr period. Under dry conditions Alberta, ...

The increasing concentration of potentially toxic elements (PTEs) in agricultural soils has greatly disturbed the quality and productivity soils. In this study, we investigated uptake distribution cadmium (Cd), lead (Pb), nickel (Ni) by two Brassica cultivars (Khanpur raya Sandal canola) grown on soil irrigated with metal-contaminated water. Distilled water was spiked salts to prepare irrigatio...

Canola (Brassica napus L., Brassicaceae) research in Virginia began in the mid 1980s. A concerted and focused cooperative effort was initiated, with USDA-CSREES-National Canola Research Program funds, in 1993 by Virginia’s two Land Grant Universities: Virginia State University and Virginia Tech. A major goal of this effort, until recently, has been establishment of canola as a domestic source o...
