Models for the evapotranspiration of greenhouse crops are needed both for accurate irrigation and for the simulation or management of the greenhouse climate. For this purpose, several evapotranspiration models have been developed and presented, all based on the Penman-Monteith approach, the "big-leaf" model. So, on the one hand, relatively simple models have been developed for irrigation scheduling purposes, and on the other, "knowledge-mechanistic" models have been developed for climate control purposes. These models differ in the amount of detail about variables, such as stomatal and aerodynamic conductance. The aim of this review paper is to present the variables and parameters affecting greenhouse crop transpiration, and to analyze and discuss the existing models for its simulation. The common sub-models used for the simulation of crop transpiration in greenhouses (aerodynamic and stomatal conductances, and intercepted radiation) are evaluated. The worth of the multilayer models for the simulation of the mass and energy exchanges between crops and air are also analyzed and discussed. Following the presentation of the different models and approaches, it is obvious that the different applications for which these models have been developed entail varying requirements to the models, so that they cannot always be compared. Models developed in different locations (high-low latitudes or for closed or highly ventilated greenhouses) are discussed, and their sensitivity to different parameters is presented.Agronomy 2019, 9, 392 2 of 17 canopy. Estimations on how much energy is absorbed by the plant depends a lot on the greenhouse characteristics (cladding material), and on the ability of the climate control equipment (if present) to automatically modify/control the relevant climate factors. With the expansion of greenhouse culture all over the world, this has led to various models for ET estimation [4][5][6][7][8]. Thus, this work aims to review and discuss the available literature on the available ET models, their basic differences, and their use under different greenhouse climate conditions. The Most Common Approaches The Penman-Monteith ModelEvaporation (from soil) and transpiration (from the crop stomata) occur simultaneously, and there is no easy way of distinguishing between the two processes [5]. However, in many cases under greenhouse conditions, the soil is covered by a mulch that may considerably reduce the evaporation [9]. In the case of a non-mulched cropped soil, the evaporation is mainly determined by the water availability at the soil surface and the part of solar radiation reaching the soil surface. The solar irradiance reaching the soil is reduced during the growing period, as the plants develop and their canopy shades an increasing fraction of the ground area. When the crop is small, water is mainly lost by soil evaporation, but once plants are well developed and completely cover the soil, transpiration becomes the main process.Crop transpiration in greenhouses could be estimated based on the crop ene...

“…In substrate culture, irrigation control requires the measurement of transpiration over short time intervals, e.g. in an hourly basis or even less (Carmassi et al, 2013). This can therefore aid in the efficient delivery of water and fertilizer supply, especially in areas with a Mediterranean climate, where water is often a scarce natural resource (Rouphael et al, 2004;Feng et al, 2017).…”

Three experiments (spring and autumn-winter seasons) with soilless cucumber crop (cv. Phenomeno) were conducted in order: (i) to calibrate the simplified Penman -Monteith model equation as affected by greenhouse microclimate (ii) to validate the prediction efficiency of the model at different climatic conditions and (iii) to establish a relationship between transpiration and leaf temperature. To determine Penman-Monteith model parameter variables related to the plants such as transpiration and leaf area index (LAI), so as environmental variables (i.e., radiation, temperature, humidity) were recorded. The results revealed that the determined model parameters were suitable for the whole cucumber cultivation cycle and a wide range of climatic conditions. However, parameterization of the model using autumn-winter crop data revealed superiority compared to spring data, as indicated by the correlation coefficients. Model validation showed a good fit between simulates and measures allowing implementation in commercial soilless practices. With respect to greenhouse microclimate, cooling affected daily mean air temperature and vapor pressure deficit, so as model coefficients. Leaf temperature indicated a good correlation with transpiration and the prediction equation was validated under different greenhouse climatic conditions. These results may be of value in Mediterranean greenhouses, enabling a more efficient water resource management without significant losses in agricultural productivity.
