abstract in order to study the effect of various densities of wild mustard (sinapis arvensis l.) on growth indices of canola (brassica napus l.) in climate of molathani, ahvaz, an experiment was conducted in the experimental field of ramin agricultural and natural resources university, in 2006-2007. the split-plot set of treatments was arranged within randomized complete block design with four ...

A fully instrumented air conditioning laboratory unit capable of controlling drying air temperature and humidity integrated with an instantaneous weighing thin layer drying system was used to investigate the thin layer drying behavior and desorption equilibrium moisture content of canola (Brassica napus L.). To this aim, freshly harvested canola samples with moisture content of about 12±0.5% (d...

The effects of a 4-year crop rotation and two tillage systems on blackleg (Leptosphaeria maculans) disease of canola were determined in a field experiment carried out from 1999 through 2002 at Carman, Manitoba. Crops in rotation were canola (Brassica napus) (C), wheat (Triticum aestivum) (W), and flax (Linum usitatissimum) (F). Rotations were done under conventional tillage (T) or zero-till (Z)...

The form and opener configuration used to apply phosphorus fertilizer can influence its effectiveness crop response. A growth chamber study was conducted examine the response of (canola, wheat, pea grown in rotation) soil P (monoammonium phosphate struvite), spread (narrow versus wide), rate treatments 0, 20, 40, 60 kg P2O5 ha−1 added canola (B. napus) seed-row, followed by wheat without fertil...

Blackleg, caused by Leptosphaeria maculans, is an important disease of oilseed rape (Brassica napus L.) in Canada and throughout the world. Severe epidemics of blackleg can result in significant yield losses. Understanding disease-yield relationships is a prerequisite for measuring the agronomic efficacy and economic benefits of control methods. Field experiments were conducted in 2013, 2014, a...

Little biochemical information is available on carbohydrate metabolism in developing canola (Brassica napus L.) silique (pod) wall and seed tissues. This research examines the carbohydrate contents and sucrose (Suc) metabolic enzyme activities in different aged silique wall and seed tissues during oil filling. The silique wall partitioned photosynthate into Suc over starch and predominantly acc...

At the State University of Ponta Grossa (UEPG), among extension activities that promote interaction between students and community is The Ohio Program, started in 1979 to support seeking international experience. In order return a systematic study communities welcomed them, extensionists were challenged by farmers compare cost profit producing canola (Brassica napus var oleifera) corn (Zea mays...

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 ...

The pending approval of the unconfined release of Roundup Ready wheat in North America has brought to the attention of regulators and scientists in North America the issue of coexistence of genetically engineered (GM) and non-GM crops. In Canada, there has been great adoption by farmers of Roundup Ready and other GM canola varieties. At the time of commercial release of GM canola in Canada no s...

Canola (oilseed rape, Brassica napus L.) is susceptible to infection by the biotrophic protist Plasmodiophora brassicae, the causal agent of clubroot. To understand the roles of microRNAs (miRNAs) during the post-transcriptional regulation of disease initiation and progression, we have characterized the changes in miRNA expression profiles in canola roots during clubroot disease development and...
