HERNANDEZ-HERNANDEZ, Fabiola et al. Growth and development simulation of pepper (Capsicum Annumm L.) under greenhouse conditions. Rev. Mex. Cienc. Agríc [online]. 2011, vol.2, n.3, pp.385-397. ISSN 2007-0934.

Greenhouse horticultural production demands practices to have the desired effect, this requires an accurately determination of deviations that occur during growth and crops development. Modeling allows having in a quantitative way the plant simultaneous processes and therefore changes in crops state variables can be anticipated. This work aims to contribute to pepper growth and development prediction using simulation. Considering the specific production conditions of Querétaro, Mexico; during 2008-2009. It discusses the implementation in pepper of a growth and development model, originally developed for tomato crop. The model used is TOMGRO (TOMato GROwth Model) simplifed, which predicts potential crop growth by solar radiation in photosynthesis (PAR), temperature and carbon dioxide amount at the experimental site. Pepper varieties used were Triple Star and Triple 4. Model parameters adjustment was made by obtaining adequate results in crop development prediction; therefore, generated model adjusted for pepper can be used in intermediate technology greenhouses in Mexico.

Palavras-chave : crop modeling; parameterization; TOMGRO simplified model.
