Calibration and validation of a biological model to simulate the development and production of tomatoes in Mediterranean greenhouses during winter period
Dimokas, G.; Tchamitchian, M.; Kittas, C. (2009)The aim of this work is to calibrate and validate the adaptation of TOMGRO (TOMato GRowth), a crop growth simulation model for tomato, to the short-term cropping technique and to conditions in Greece. Current practice in ... -
Case studies of a modified biological simulator (TOMGRO) according to short cropping period
Dimokas, G.; Katsoulas, N.; Kittas, C.; Tchamitchian, M. (2012)The aim of this work was to perform a sensitivity analysis of a modified biological simulator (TOMGRO) in tomato crop during winter period. The modified biological simulator (TOMGRO) that used for case studies of the ... -
Daily temperature optimisation in greenhouse by reinforcement learning
Tchamitchian, M.; Kittas, C.; Bartzanas, T.; Lykas, C. (2005)The goal of this study is to show the usefulness of reinforcement learning (RL) to solve a common greenhouse climate optimisation problem. The problem is to minimise the daily heating cost while achieving simultaneously ... -
Development of a bio-physical simulator for Mediterranean greenhouses
Dimokas, G.; Katsoulas, N.; Kittas, C.; Tchamitchian, M. (2011)The aim of this work was the development and validation of a biophysical model (BioSiGreT) by coupling a crop growth model and a greenhouse climate model. The crop growth model is a modification of TOMGRO to simulate ... -
Development of a simple growth model for light control in tomato seedling production
Peponakis, C.; Katsoulas, N.; Petsani, D.; Kittasa, C.; Tchamitchian, M. (2009)Models are necessary for application of automatic control on any process in greenhouses. Despite the existence of several tomato crop growth models, no models are available for tomato seedlings. In the present paper, a ... -
Effect of grafting on eggplant leaf gas exchanges under mediterranean greenhouse conditions
Khah, E. M.; Katsoulas, N.; Tchamitchian, M.; Kittas, C. (2011)Grafting is an easier and faster approach than plant breeding to take advantage of both existing resistant plants, especially wild cultivars, and high-bred cultivars. The aim of this study was to investigate the changes ... -
Influence of the heating method on greenhouse microclimate and energy consumption
Bartzanas, T.; Tchamitchian, M.; Kittas, C. (2005)The influence of the heating system method on greenhouse microclimate was investigated overnight, using an experimental greenhouse tunnel with a tomato crop. The heating system consisted of plastic heating pipes located ... -
Validation of a tomato crop simulator for Mediterranean greenhouses
Dimokas, G.; Kittas, C.; Tchamitchian, M. (2008)The aim of this work is the validation of the adaptation of the TOMGRO tomato crop simulation to short term cropping technique and to Greek conditions. Indeed, a current practice in plastic greenhouses in the Mediterranean ...
