| Abstract/Contents: | "Canopy gross photosynthesis of tall fescue receiving three to four rates of N fertilization was studied under field conditions during three contrasting growing seasons. Under non-limiting N growing conditions, the growing seasons did not have a significant effect on the maximum canopy gross photosynthesis (canopy gross photosynthesis at saturating PAR) and the maximum light yield (quantum efficiency of the canopy at low PAR). In the absence of N fertilization and for a similar LAI, the values of the maximum canopy gross photosynthesis were approximately equal to 70% of those obtained under non-limiting N conditions. This response of the tall fescue canopy to N concentration is much smaller than that reported at the leaf level. The reduction in canopy photosynthetic capacity with no N applied compared to non-limiting N conditions is much less than the reduction observed previously in above-ground dry matter accumulation. The effect of N fertilization on above-ground dry matter accumulation is due primarily to changes in C partitioning and the resulting faster leaf area development and greater light interception rather than the effect of N on the canopy photosynthetic capacity per se." |
