Organic rotational no-till system adapted for Manitoba, CanadaHalde, Caroline January 2014 (has links)
In the northern Great Plains of Canada, there has been limited research conducted on reduced-tillage grain production systems managed organically. The objective was to adapt an organic rotational no-till system to the growing conditions of Manitoba, and to test its agronomic performance. A set of four experiments were conducted between 2010 and 2012, in Carman, MB, Canada. Mulches with hairy vetch (Vicia villosa Roth) showed the most promising results, producing the highest mulch biomass and organic no-till spring wheat (Triticum aestivum L.) yield. Organic flax (Linum usitatissimum L.) yield was significantly higher in no-till than in the two tillage treatments. Reduced content of soil nitrate-N and perennial weeds limited crop productivity after 4 yr under organic continuous no-till. In conclusion, the successful adaptation of the organic rotational no-till system to the growing conditions of Manitoba eliminated the need for tillage for a period of 1.5 to 2 yr.

Pasture renovation with herbicide suppression of weeds and no-till seeding of orchardgrassFitzsimmons, James P. 17 June 1993 (has links)
No-till pasture renovation can increase the quality and forage yield of
underproductive pastures. Decreased erosion, lower costs, and less lost
grazing time are advantages of no-till renovation compared to conventional
renovation. Unwanted vegetation is first controlled with herbicides to decrease
competition for introduced orchardgrass. Two field trials were conducted using
a split-plot design to compare three seeding methods and two herbicides. An
Aerway no-till drill, a Tye double disk drill, and broadcast followed by harrowing
were the seeding methods. Paraquat and glyphosate were used to determine
herbicide effect on vegetation control.
Orchardgrass did not adequately survive at either trial site. However,
where some orchardgrass did survive, vegetation control was more important
than seeding method. Competition from annual grasses, many germinating
after herbicides were applied, was the reason for renovation failure. Herbicide
and initial growth for best control.
Yield was doubled in the first harvest by the addition of fertilizer. Early
spring forage production from poor pastures is usually more than adequate, so
the increase from fertilizer is of marginal value unless it is stored for later use.
Yield increase did not carry over to the second harvest when it could be better
utilized. Later application dates would extend yield increases from certain
species if water is available. / Graduation date: 1994
