Eight years of annual no-till cropping in Washington’s winter wheat-summer fallow region
The tillage-based winter wheat (Triticum aestivum L.)-summer fallow (WW-SF) cropping system has dominated dryland farming in the Pacific Northwest USA for 125 years. We conducted a large-scale multidisciplinary 8-year study of annual (i.e., no summer fallow) no-till cropping systems as an alternative to WW-SF. Soft white and hard white classes of winter and spring wheat, spring barley (Hordeum ...
متن کاملCharacteristics of water consumption in water-saving winter wheat and effects on the utilization of subsequent summer rainfall in the North China Plain
Winter wheat (Triticum aestivum L.) grows in dry season but summer maize (Zea mays L.) coincides with rainfall in the North China Plain (NCP). Increasing rainfall use efficiency and harmonizing its utilization between the two species is an effective way to mitigate impact on groundwater deriving from wheat irrigation. One to four times water supply (W1, to W4) were employed in wheat, three wate...
متن کاملEffect of Corn, Sugarbeets, and Fallow on Zinc Availability to Subsequent Crops
Field observations indicated that Zn deficiency of beans (Plasscoins melons L.) was sometimes more severe than expected when grown on Mowed soil that was low to marginal in available Zn. The objectives of this study were to determine the effects of fallow, suprbeets (Beta Moods L.), and corn (Zea mays L.) on Zri availability to subsequent crops grown on a Portneuf silt loam (Durixerollic Calcio...
متن کاملSimulated yield and profitability of five potential crops for intensifying the dryland wheat-fallow production system
Greater precipitation use efficiency (PUE) and economic returns by increasing cropping frequency through the addition of summer crops to the dryland winter wheat-fallow (WF) cropping system have been reported in the semiarid Central Great Plains of USA. However, due to the highly variable nature of precipitation and uncertain water availability, selection of a crop with assured positive net ret...
متن کاملWinter 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 ...
