Treasure spring wheat was grown using conventional furrow irrigation and surge irrigation on 12 one-half-acre plots. Both systems were operated simultaneously five times during the season. Conventional irrigation applied 24.7 ac-in of water with runoff of 5.6 ac-in and infiltration of 19.1 ac-in. Surge irrigation applied 12.0 ac-in with 1.7...
Surge irrigation of furrow-irrigated spring wheat was investigated at the Malheur Experiment Station in 1991. The project studied the feasibility of implementing surge as an irrigation management method for increasing irrigation efficiency and reducing deep percolation of irrigation water from furrow-irrigated fields in Malheur County.
Surge irrigation is a process...
Treasure spring wheat was grown on sloping ground with and without mechanically applied furrow mulching. Furrow mulching used 800 lb/ac of wheat straw. Mulched and non-mulched furrows were irrigated five times during the season receiving 483 and 19.0 and 40.9 ac-in of irrigation water, respectively. For non-mulched furrows, infiltration totaled...
The potential of mechanically applied straw mulch to reduce nutrient, pesticide and sediment losses from furrow irrigated onions and increase water use efficiency was evaluated on a Nyssa silt loam with three percent slope. Nitrogen and phosphorus losses in the runoff were of particular interest, both because of their economic...
Russet Burbank, Shepody, Frontier Russet, and Ranger Russet potatoes were tested for their response under furrow irrigation to PAM-treated irrigation water. The use of PAM was associated with an increase in US Number One tubers for Russet Burbank and Shepody varieties.
Native shrublands and their associated grasses and forbs have been disappearing from the Great Basin as a result of grazing practices, exotic weed invasions, altered fire regimes, climate change and other human impacts. Native forb seed is needed to restore these areas. The irrigation requirements for maximum seed production of...
Native grass, forb, and shrub seed is needed to restore rangelands of the U.S. Intermountain West. Fernleaf biscuitroot [Lomatium dissectum (Nutt.) Mathias & Constance] is a desirable component of rangelands. Commercial seed production is necessary to provide the quantity and quality of seed needed for rangeland restoration and reclamation efforts....
