in order to study crop rotation, chemical control and their interactions on weeds density of wheat fields, an experiment was conducted in a split plot arrangement in randomized complete block design with three replications in gorgan agricultural research station for five years. in this study, 10 rotational crops: canola, fababean, barley, white pea, soybean, cotton, maize, sorghum, millet and w...

Since the first commercial release of genetically modified (GM, also referred to as genetically engineered, GE) crops in the middle of 1990s, the research and development of transgenic biotechnology has made dramatic progress. To date, global cultivation area of GM crops has exceeded 120 million hectares (James, 2009) with extensive cultivation of herbicide-tolerant soybean and canola, insect-r...

Starches of varying chemical structures were esterifi ed with anhydrides, formulated into dry fi lm lubricants with the addition of canola oil, and its friction properties investigated. In the absence of canola, chemically modifi ed starch displayed a very high coeffi cient of friction (COF). Addition of canola resulted in a sharp decrease in COF, which decreased with increasing [canola] until ...

Interest is increasing in the potential cardioprotective role of -3 (n-3) fatty acids (FAs). Most of the evidence supporting this hypothesis has been derived from studies of the longer-chain members of the n-3 family, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), found in fish oils.1 The value of the shorter-chain cousin, -linolenic acid (ALA), found in certain plant oils (flaxsee...

the aims of the present study was to evaluate the level of aflatoxin b1 (afb1) in feedstuffs (corn silage, corn, dried alfalfa, cottonseed meal, cottonseed, soybean meal, canola meal, barley, wheat bran, concentrate, sugar beet pulp and wheat straw) that collected from dairy herds in khorasan razavi province that classified according to milk yield in very high (>10000 kg/day), high (5000-10000 ...

The global cultivation area of genetically modified plants (GMPs) includ ing soybean, maize, cotton, canola (oilseed rape) and sugar beet has been increasing consistently since they were first cultivated commercially in 1996, reaching 160 million hectares (ha) in 2011 [1]. By 2011, the global area of planted insectresistant crops was 66 million ha. The rapid adoption of insect-resistant crops i...

Herbicide carryover injury to rotational crops can vary in severity depending on the influence of soil properties herbicide bioavailability. Greenhouse bioassays were conducted with soybean, radish, and canola evaluate differences bioavailability three herbicides risk, atrazine, mesosulfuron-methyl, topramezone. Bioassays varying regional types nine treatment rates including a control. Plant vi...

Canola production in Australia has increased dramatically leading to an increase in canola meal. Limits have been placed on the intake of canola meal as an animal feed due to its high levels of anti-nutritional components. Sinapine, one such component, is the major phenolic compound found in canola meal. Previous studies have suggested that sinapine concentrations may be lowered through a breed...
