“…In this study, in both experiments, the crop cycle was 68 days. The local climatic conditions and the use of plastic mulch accelerate crop development (Qin et al, 2014), including fruit maturation (Lovelli et al, 2008). Such adjustments in the duration of phases must be considered in the irrigation management to avoid excess applications.…”

“…In addition, polypropylene webs -agrotextiles -are installed over the plant rows to minimize insect attacks, especially by the silverleaf whitefly and the leaf miner fly. Both plastic mulch and polypropylene webs influence the microclimate near plants, including temperature, net radiation, relative humidity, wind speed and accumulated degree-days (Diaz-Perez, 2009;Gimenez et al, 2002), and this microclimate affects evapotranspiration and water use of plants (Lovelli et al, 2008, Qin et al, 2014.…”

Methods for obtaining evapotranspiration based on energy balance are potentially interesting for analyzing the impact of crop management practices on energy fluxes and, thus, the loss of water from the plant surface. Among the methods for estimating ET based on energy balance, the Bowen Ratio Energy Balance (BREB) has been well evaluated and is recommended by several authors for different crops (Irmak, et al., 2013;Hou et al., 2010;Zhang et al., 2010;Zeggaf et al., 2008).This study applied the BREB method to determine the crop coefficients of irrigated melon grown with plastic mulch and agrotextiles in the region of Mossoró, state of Rio Grande do Norte, Brazil, to provide more locally appropriate information to irrigators to maintain high yields with more efficient use of water.

“…Crop evapotranspiration assessment is necessary to correctly quantify crop irrigation water needs, playing a crucial role in cooling greenhouse crop canopies [112]. In order to evaluate crop evapotranspiration (ET C ), environmental conditions and physical, morphological and physiological features of soil-plant systems have to be considered [113].…”

Precision agricultural greenhouse systems indicate considerable scope for improvement of irrigation management practices, since growers typically irrigate crops based on their personal experience. Soil-based greenhouse crop irrigation management requires estimation on a daily basis, whereas soilless systems must be estimated on an hourly or even shorter interval schedule. Historically, irrigation scheduling methods have been based on soil or substrate monitoring, dependent on climate or time with each having both strengths and weaknesses. Recently, plant-based monitoring or plant reflectance-derived indices have been developed, yet their potential is limited for estimating the irrigation rate in order to apply proper irrigation scheduling. Optimization of irrigation practices imposes different irrigation approaches, based on prevailing greenhouse environments, considering plant-water-soil relationships. This article presents a comprehensive review of the literature, which deals with irrigation scheduling approaches applied for soil and soilless greenhouse production systems. Irrigation decisions are categorized according to whether or not an automatic irrigation control has the ability to support a feedback irrigation decision system. The need for further development of neural networks systems is required.

“…These resistances are used widely in evaluating ET through their interactions with canopy physiology, radiation dynamics and atmospheric factors (Drexler et al 2004;Molder and Kellner 2001). Applications of r a in crop and pasture systems have proved effective and to operate well using a logarithmic wind profile and parameters related to crop geometry, while parameterization of r s is rather complex owing to tremendous differences in canopy physiology and hydrologic conditions in different ecosystems (Lovelli et al 2008). Nevertheless, the Penman-Monteith equation allows the evaluation of the main driving forces of ET through boundary conditions in mires (Admiral et al 2006;Sun and Song 2008).…”

Data from four components of the radiation balance were used to investigate the surface energy budgets for a Carex lasiocarpa mire in the Sanjiang Plain, Northeast China, and the controlling factors of the evapotranspiration (ET) were discussed in detail. During the growing season 2006, the shortwave radiation (SW↓) reaching the mire surface added up to 2,854.3 MJ m(-2) and the net radiation (Rn) was 1,637.4 MJ m(-2) in total, with an average of 9.86 MJ m(-2) day(-1). G was the smallest flux at the water-atmosphere interface, with an average of about 0.91 MJ m(-2) day(-1), but showed high relative variability, even changing its sign. The latent and sensible heat fluxes (LE and H) amounted to 787.48 and 476.26 MJ m(-2), respectively, and the total sum of LE and H accounted for 77.18% of Rn. By conversion from LE, the average value of ET from the mire was 1.84 mm day(-1), amounting to 298.8 mm. The total ET was almost 60% of the total rainfall in the same period, proving that ET is the primary water consumer in the mire. The growth of C. lasiocarpa was related closely with surface resistance (r (s)), and analysis of partial correlation indicated that r (s) correlated negatively with leaf area index (LAI) when the interference of the available energy, Rn-G, was removed. There was a strong linkage between r (s) and the evaporative fraction [LE/(LE + H)] as well as Bowen ratio (β). r (s) was the key factor in controlling the variation of ET and regulating energy partitioning between LE and H. During the whole growing season, r (s) and R (n)-G were the two main factors coupled in ET processes. In spring, r (s) dominated ET processes, and the increase in LAI led to a decrease in r (s), which in turn accelerated ET as vegetation developed until late August. After August, the available energy controlled the process of ET completely until ET reached an equilibrium in mid-October.
