Abstract/Contents:"The extended logistic model of crop response to applied nutrients provides a quantitative coupling of seasonal dry matter (Y), plant N uptake (Nu), and plant N concentration (Nc) with applied nutrient (N). It predicts a hyperbolic relationship between Y and Nc with Nu. Analysis of data from numerous studies has confirmed the model. In this article the model was applied to data for Midland and Tifton 44 bermudagrass (Cynodon dactylon L.) grown on the same soil in Oklahoma. Results showed that the intercept parameters b and bn, as well as the nitrogen response coefficient c, were common to the two cultivars. The difference was accounted for in yield parameter A and plant N uptake parameter An. Applied N required to achieve 50% of maximum yield was 92 kg ha-1 for both cultivars."
