Evapotranspiration In Tomato Plants Grown Under Controlled Environment In Mexicali Baja California, Model Prototipe Based On the Solar Radiation

The determination of evapotranspiration is one of the multiple basic elements to consider to calculate the hydric requirements of a crop. Therefore, it is important to realise precise estimations of each crop and for each environmental condition. There are several procedures using many formulate, however they are very general and they demonstrate the local character for certain regions. Considering the previous situation, in this work a model prototype for the calculation of the monthly evapotranspiration considered for plants of tomato (Lycopersicon esculentum Mill.) grown under controlled environment is presented, using data of water evaporation obtained according to the received radiation, transpiration of foliar area and estimated number of estomas. Values of radiation reported for the Valley of Mexicali Baja California Mexico was used. This model turned out to be effective to consider the water needs of the tomato crop grown under controlled environment of Valley of Mexicali Baja California México
