A model of growth and sugar accumulation of sugar beet for potential production conditions: SUBEMOpo II. Model performance
نویسنده
چکیده
A model SUBEMOpo, to simulate sugar beet growth and sugar accumulation for potential production conditions has been evaluated. Given initial conditions, the growth, development and sugar accumulation of the model are driven by observed weather (i.e. maximum and minimum temperatures, rainfall, wind speed, relative humidity and solar radiation). Soil water and nutrients are considered as non limiting in the model. To evaluate the model, results of historical ®eld trials as well as of ®eld trials especially conducted for this evaluation study were used. These data concern growth, yield and sugar content of sugar beets grown on sandy, loess and clay pro®les in Belgium and the Netherlands during several growing seasons. The agreement between measurements and simulation results is so far acceptable. The weakest section of SUBEMOpo is the partitioning of dry matter between structural and non structural dry matter of the tap root. # 2000 Elsevier Science Ltd All rights reserved.

A model of growth and sugar accumulation of sugar beet for potential production conditions: SUBEMOpo I. Theory and model structure
SUBEMOpo (SUgar BEet MOdel potential production) is a mechanistic simulation model to simulate sugar beet growth and sugar accumulation for potential production conditions. Under those conditions sugar beet growth and sugar accumulation are entirely controlled by the prevailing weather (radiation, temperature) and by the crop characteristics (plant density). The only site characteristic require...

The rapid population growth and the need for more agricultural production necessitate more attention to water shortage and enhancing water productivity. To assess water productivity and supply:demand ratio index in sugar beet, this experiment was carried out using SUCROS growth simulation model. Long-term climatic data and collecting questionnaires from farmers were used to assessing water prod...

Defoliation produced by abiotic factors and the subsequent re-growth can reduce sugar beet (Beta vulgaris L.) sucrose content and final sugar yield. Field experiments were conducted during 2003 and 2004 growing seasons in the farm of Hellenic Sugar Industry SA, Larissa factory, central Greece. Three sugar beet cultivars (Rival, Europa and Corsica) were ordinary irrigated till the beginning of J...
