Winter Pea: Promising New Crop for Washington's Dryland Wheat-Fallow Region
A 2-year tillage-based winter wheat (Triticum aestivum L.)-summer fallow (WW-SF) rotation has been practiced by the vast majority of farmers in the low-precipitation (<300 mm annual) rainfed cropping region of east-central Washington and north-central Oregon for 140 years. Until recently, alternative crops (i.e., those other than WW) so far tested have not been as economically viable or stable ...
متن کاملAllelopathic Potential of Various Plant Species on Downy Brome: Implications for Weed Control in Wheat Production
Allelopathy, the ability of plants to inhibit germination of other plants, is an untapped resource for weed control in crops that could revolutionize organic crop production. The main objective of the study was to evaluate allelopathic potential of various plant species on downy brome (Bromus tectorum L.), a major pest of wheat (Triticum aestivum L.). To screen for potential allelopathy, plants...
متن کاملRehabilitating Downy Brome (Bromus tectorum)–Invaded Shrublands Using Imazapic and Seeding with Native Shrubs
Rehabilitation of downy brome–infested shrublands is challenging once this invasive grass dominates native communities. The effectiveness of imazapic herbicide in reducing downy brome cover has been variable, and there is uncertainty about the impacts of imazapic on native species. We used a before-after-control-impact (BACI) field experiment and greenhouse studies to (1) determine if imazapic ...
متن کاملTitle : Developing Sustainable and Profitable Cropping Systems for North - Central Oregon
of Research Findings The project has now completed two crop-years of experimentation. Four more crop-years are required for all crop rotations to complete a full cycle. This report covers the 2004-05 cropyear results. CBARC experiment (Moro): Grain yields of winter wheat following fallow (conventional or chemical) produced significantly higher yields than yields of annual cropping systems invol...
متن کاملUptake coefficients for biosolids-amended dryland winter wheat.
The USEPA adapted a risk assessment approach in biosolids regulations that includes the use of an uptake coefficient (UC) (i.e., the ratio of plant concentration to quantity of element added) to determine limitations on selected elemental additions. The nature of the risk assessment requires UCs to be constants. Our hypothesis was that the UC for Cu, Fe, Mo, Ni, P, and Zn for biosolids-amended ...
