| Banding and sidedressing nitrogen (N) fertilizer on a never-irrigated side of a row of corn (Zea mays L.) were hypothesized to maintain yield and decrease nitrate leaching. In a two—year ?eld study on a Portneuf silt loam (Durinodic Xeric Haplocalcid) in southern Idaho, we evaluated effects on yield and N uptake of 1) urea placement (broadcast pre-plant vs. band at planting), 2) row spacings (30-in vs. an offset 22—in spacing in which every pair of 22-—in rows was positioned close to a furrow rather than each row on a bed center), and 3) water management. Our water management, termed irrigated furrow positioning, consisted of every- second furrow irrigation in which we applied water to either a) the same or b) the Opposite side of the row with... |

| The decision to fall or spring bed potatoes is often dictated by weather and processor contract agreements. Although there are advantages to both fall an( spring bedding, soil conditions are often wet in the spring in Malheur County, Oregon. Spring bedding of wet soils leads to soil compaction and decreased water infiltration. The primary objective of the study was to determine the effects of fall or spring bedding on tuber yields and quality under furrow irrigation. Determining the most effective method of fall potato ground preparation was the second objective of the trial. Land for potato production is normally moldboard plowed in the fall. Chisel plowing may provide better placement of residues in bedded ground and thus promote higher... |
