Abstract/Contents: | "Quantitative knowledge of the interactive effects of soil drainage and N fertilization on water use efficiency (WUE) of grasses growing on floodplains in the northeastern United States is scant. Our objective was to quantify the effects of soil drainage and N fertilization on water use efficiency of perennial ryegrass. The study was conducted for two years on a floodplain in central Pennsylvania on two soils selected for soil drainage conditions. A tetraploid, forage-type, perennial ryegrass (Lolium perenne L., cv. Bastion) was treated with a split application (50%/ 50%) of 0, 84,168, and 252 kg N ha⁻¹ as ammonium nitrate. Overall, denitrification caused by poor soil drainage conditions during the spring growth period resulted in a 26 percent reduction in WUE. During the summer growth period, the reduction of WUE was 20 percent. These reductions in biomass yield resulted mostly from lost N fertilizer value due to denitrification." |
