background and objectives. integrated weed management approaches can help to decline costs weed control and improve its condition. critical period of weed control (cpwc) is defined as the best time for weeding. if cpwc is recognized we can accurately use herbicides and prevent environmental pollutions. beginning and duration of cpwc despond on some agents such as crop and weed traits, environme...

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)...

This study, intending to understand the effects of crop rotation and tillage on blackleg disease, was conducted in a field at Carman, Manitoba, Canada, from 1999 – 2002. Canola, wheat and flax were among the rotated crops. Rotations were performed under conventional or zero-till conditions. The number of infected plants, infected leaves per plant, lesions per plant, and percentage of leaf cover...

Grain yield in wheat is influenced directly and indirectly by other plant characteristics. One of the main goals in wheat breeding programs is increase of grain yield. Considering the role of crop rotation in increasing grain yield, and in order to study the difference between crop rotations for wheat yield and yield components (Darya cultivar), an experiment was conducted with six rotation tre...

Rapid expansion of the processing potato industry has contributed to a significant increase in irrigated potato production in Manitoba. However, information is lacking regarding optimum rotations for local conditions. In 1998, a crop rotation study was initiated on a Wellwood silt loam near Carberry to identify crop rotations that optimized crop yield and quality while maintaining soil quality....

T description of work in refs 206 and 207 was incorrect. Although glyphosate was applied to fields/crops prior to wheat or barley, GR soybean was not in the rotation. Canola was one rotation crop that preceded wheat or barley, but the authors were not sure if it was GR or not (although it is likely based on the statement that the canola was sprayed with glyphosate in ref 207). The paragraph wit...

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...
