“…Water savings can reach 20-30% thus, (WUE) is increased. These results were in agreement with those obtained by Pirkner et al (2014) whey showed that, the horticultural measures of flowering and fruit yield characteristics were the higher under screenhouse; hence, their results suggest a potential increase in water use efficiency under the screenhouse. CONCLUSION Screenhouse utilization became utmost important in banana cultivation as it could modify the microclimate to make it proper for banana plants cultivation.…”

“…Shading reduced losses and thus increased the marketable fruit yield compared to growth under non-shaded conditions. Likewise, Pirkner et al (2014) showed that estimated reference evapotrans -pirations were lower under the screenhouse. However, the horticultural measures of fruit yield characteristics were the higher under screen house, and hence, their results suggested a potential increase in productivity under the screenhouse.…”

Screenhouses utilization is rapidly expanding nowadays; so in this investigation, the effect of screenhouse and its colors on banana cv. Grand Naine productivity, in relation to some microclimate elements (such as temperature, humidity, wind speed and light intensity inside the screenhouses) and the water use were recorded. Also, productivity parameters such as bunch weight, length, number of hands and number of fingers per hand were recorded. Water saving by using three different levels of irrigation was estimated. The obtained results revealed that, maximum temperature of screenhouses decreased by 1-2 o C, minimum temperature increased by approximately 1 o C , the intensity inside the screenhouses increased by approximately 30 % and about 40 % reduction in wind speed. Also humidity increased by 4-6 % and 30 % reduction in crop water use inside the screenhouses, without any significant reduction in productivity as compared to open field. The obtained results may be due to the reduction of evapotranspiration caused by screenhouse. Finally, we can recommend that: it is most importance to plant banana orchards into screen houses in order to minimize crop water use and enhance every the yield and fruit quality.

“…Similar findings have been presented in the past where shading has been shown to improve the crop yield for wide variety of crops at different geographical locations [43][44][45]48]. In one study on bell pepper plant under shading, the net photosynthesis was relatively unaffected for 30% to 47% shade level and the leaf mineral nutrients increased with increased shading levels within this range [44].…”

“…While canopy shading can effectively reduce crop ET leading to water saving, it must not be at the expense of reduced crop yield. There have been several studies in the past where the effect of shading on the crop yield has been studied [42][43][44][45][46]. Based on these studies, under typical moderate shading conditions (shading level < 50%), crop yields have been shown to improve or being unaffected by shading.…”

California has some of the key agricultural regions in the United States. One of these key regions, San Joaquin Valley, frequently experiences severe droughts leading to shortage of irrigation water. This has a significant impact on the agricultural based economy of the region. It is imperative to develop new strategies to reduce overall water consumption in agriculture without affecting crop yield. A large fraction of irrigation water is lost due to the evapotranspiration (ET) process in the crops and the soil. The classical Penman-Monteith model has been used in the present work to analyze the effect of different environmental variables and water saving strategies on the ET. Some of the scenarios considered show potential for significant water savings without much reduction in the amount of sunlight available to facilitate crop growth. The central idea considered in this study is the use of canopy shading to cover the crop field resulting in reduction in the ET. Among the strategies considered, the most promising strategy is to partially cover the crop field for a certain part of the day by employing a partially covering retractable canopy. Based on numerical calculations, total reduction in ET is calculated to be 37% from June to August for the partially covering retractable canopy.

“…The use of these insect screens causes alterations to the microclimate generated inside the SH mainly due to a modification of the air movement regime and a reduction in air speed which could cause a decrease in CO 2 levels, increases in humidity and temperature that can influence plant physiological processes such as photosynthesis and transpiration rates with negative effects on crop growth and development (Bournet & Boulard, 2010). Although it should be noted that these microclimate alterations are generally less drastic in greenhouses with plastic cover and with a good management of the screens is possible to reduce the indoor temperature (Pirkner et al, 2014;Perillo et al, 2015;Liu et al, 2017;Xu et al, 2017).…”

In developing countries, horticultural production in low-altitude tropical climate conditions is often limited by biotic and abiotic factors. In these countries, the implementation of highly technical greenhouses is not feasible due to economic, social and cultural issues related to farmers. Therefore, one of the alternatives that has taken a great boom is the use of screen house structures (SH), although information on the microclimatic behavior of these is still limited. The objective of this research was to use an experimentally validated 3D CFD numerical simulation model to study the thermal behavior and airflow patterns in an SH located in the Colombian Caribbean region during the daytime hours (6:00 to18:00 h). The results obtained showed that the air flow patterns inside the SH showed speed reductions of up to 68% with respect to the speed of the external wind. It was also found that the thermal behavior inside the SH was quite homogeneous, the average temperature values in the structures ranged between 23.9 and 39 °C and the difference with external environment temperature did not exceed 1.8 °C. It was concluded that the implementation of this type of structure could be an useful technological tool for the optimization of horticultural production in low-altitude tropical climate regions.
