| Abstract/Contents: | "A low water table (LWT) and high water table (HWT) of 76 and 20 cm were maintained in 4 and 8 concrete tanks, respectively, filled with organic soil. Four HWT tanks were fertilized with 100 kg of N ha-1 every 28 days. Each tank was planted with St. Augustinegrass (Stenotaphrum secundatum) Callie bermudagrass (Cynodon dactylon) and alemangrass (Echinochloa polystachia). Dry matter (DM) and N yields of grasses were lower (P<.01) in HWT plots than in LWT plots. Addition of N to the HWT plots improved (P<.01) DM and N yields. Grasses from LTW plots were lower in neutral detergent fiber (NDF); and higher N, percentage of leaf and in vitro organic digestibility (IVOMD)(P<.01) than those from HWT plots. The NDF, N and IVOMD of leaf and stem tissue followed the same trend. Addition of N to HWT plots did not affect measures of forage quality; indicating that water table, per se, affects the nutritive quality of grasses. The Ca and P in grasses from LWT plots was higher and lower (P<.01), respectively, than from both HWT treatments. Mo in grasses from HWT plots without N was 2.5 times higher than from LWT plots." |
