Plant-available phosphorus (P) measured by routine soil-test methods is poorly correlated with rice grain yield in Arkansas. Our objective was to determine whether soil water pH (pHw) and Mehlich-3 P were correlated with growth and yield of rice grown on silt loam soils. Data from 35 field studies were used to correlate Mehlich-3 P and pHw with relative yield, dry matter accumulation, and P concentration at the midtillering stage. Significant linear or nonlinear relationships between pHw or Mehlich-3 P with rice growth parameters were delineated but explained less than 27% of the variability in dry matter and P concentrations at the midtillering stage and grain yield at maturity. Mehlich-3 P and pHw together explained 61% of the variability in midtillering P concentrations. Midtillering whole-plant P concentrations were positively related to relative grain yield and dry matter production and will be used to identify soils with limited P availability for rice in Arkansas. |
