| 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... |
