1. Potential production: determined by crop variety, crop management, radiation and temperature;
2. Water-limited production, where water availability limits the potential production.
3. Nutrient-limited production where nutrient availability limits the water-limited production
However, nutrient-limited production in WOFOST but is not implemented in a biophysical way (see section 2.1.2 of the WOFOST manual). Nutrient-limited production is obtained through post-processing of the water-limited production results. Further reducing factors (weeds, pests, frost and diseases) are not taken into account in WOFOST."; function tShowHide(id, show) { var s = document.getElementById("desc"); if ((s.innerHTML.length<=212 || show==1) && show!=2) { s.innerHTML = fDesc[id]; if (document.getElementById('m1')) document.getElementById('m1').style.display='none'; if (document.getElementById('m2')) document.getElementById('m2').style.display='none'; if (document.getElementById('more_txt')) document.getElementById('more_txt').style.display='inline'; } else { s.innerHTML = ''; } }
