Phenological and Cultural Studies of Common Dandelion (Taraxacum officinale Weber)
… were clipped more frequently and at a lower stubble height exhibited less reproductive and vegetative vigor than plants that were clipped less frequently and at a higher stubble height.

Development of Sustainable Harvest Strategies for Cellulose-Based Biofuels: Harvest Effects on Game Bird Production
… bird production. Three haying treatments (10-cm stubble, 30-cm stubble and a no-harvest control) were assigned randomly to fields harvested in the fall of 2009 and 2010 prior to sampling the subsequent summers. Nests were located, identified by species, and followed to completion using the chain …

Comparing simple and complex native forage mixtures for grazing cattle in southwestern Saskatchewan
… southwestern Saskatchewan. Clippings at a 5 cm stubble height occurred on June 20 and every 28 days after until October 10. Forage DM production, in vitro OMD, NDF, ADF, ADL, CP, Ca and P concentrations were measured. As species matured, production and OMD declined (P¡Ü0.05) but NDF, ADF and ADL …

Regrowth of Festuca hallii (Vasey Piper) and Stipa curtiseta [(A.S. Hitch.) Barkworth] following defoliation on a hummocky landscape in Central Saskatchewan
… to determine the effects of mowing to a 7.5 cm stubble height on the growth of Festuca hallii (Vasey) Piper and Stipa curtiseta (A.S. Hitch.) Barkworth. Green standing crop (GSC), dead standing crop (DSC) and above ground net primary production (ANPP) were compared to an unmowed control after a …

Development of Sustainable Harvest Strategies for Cellulose-Based Biofuels: The Effect of Intensity and Season of Harvest on Cellulosic Feedstock and Upland Nesting Game Bird Production
… on biomass yield (4) determine the effect of a stubble height (high-intensity, low-intensity, and a “no harvest” control) on nesting success of economically important bird species, (5) determine how vegetative structure and composition affect nesting success and diversity of economically …
