| Sumario: | Crop shoot mass production is often estimated from intercepted photosynthetically
active radiation (iPAR), which when divided into accumulated shoot mass gives
radiation use efficiency (RUE) for mass production. Management practices signif
icantly influence mass production and are frequently evaluated through their effects
on iPAR and RUE. While plant density’s effect on iPAR is well recognized, mainly
through its influence on leaf area index (LAI), its impact on RUE has received com
paratively limited attention. Theoretical derivations suggest that RUE should remain
relatively stable across differing LAI, with potentially slightly smaller values at very
low LAI. This study provides a comprehensive review of existing literature on the
effects of plant density on RUE under optimal growing conditions in maize (Zea
maysL.),examiningfactorscontributing to variability in RUEresponsestoplantden
sity reported across studies. Results indicate a general agreement that RUE is largely
unaffected by plant density within the tested range of LAI and for crops grown under
non-stressed conditions. |
