The amount of water and fertilizers used in the production of vegetables, specifically tomatoes, is high. This study was carried out to determine water and fertilizers use efficiency in closed and open hydroponic systems for tomato production under greenhouse conditions. Two treatments with eight replications were assessed; each replication consisted of 67 pots with two plants each. One treatment was a closed hydroponic system (with nutrient solution recirculation), and the other was an open hydroponic system (with non-recirculating nutrient solution). We quantified the amounts of water and fertilizers applied, as well as the losses (drained nutrient solution), in the two treatments during the entire cycle of tomato. In the nutrient solution (NS) we also measured electric conductivity (EC), pH, volume applied, and volume drained, and total weight of fruits (25 pickings). There were no significant differences between the two treatments on fruit production. Water use efficiency was 59.53 kg/fruit/m3 for the closed system and 46.03 kg/fruit/m3 in the open system. In comparison to the open system, the closed system produced 13.50 kg more fruit per cubic meter of water, while 10.31 grams less fertilizers per kilogram of fruit produced were only applied. Water and fertilizers use efficiency were higher in the closed system, by 22.68% and 22.69%, respectively. More efficiency was obtained in the closed system, regarding the open system. We concluded that the closed system is a good alternative to produce tomato and preserve the resources involved in the process (like water and fertilizers), thus reducing pollution.

“…According to Huang et al (2011), leaves show plasticity in their morphological characteristics due to environmental conditions, and Dousseau et al (2007) reported that with more light, they tend to have a higher number of leaves, which corroborates the present study at 45 DAT. In a study with eggplant, Costa et al (2017) reported that depending on the type of container in which the plant is submitted, the environment may promote different developments. Dalastra et al (2016), in a study on different shading levels, stated that the number of leaves is a genetic trait, which can vary according to cultivar, environment, and other attributes.…”

Ornamental pepper plants produced in containers under protected environments have high added value. We carried out research with an aim to evaluate the growth and development of ornamental pepper in containers of different colors under two protected environments, both with thermal-reflective screens under a polyethylene film: one with 18-22 % shading and the other with 42-50 % in colored containers (brown, blue, black, and red). The treatments formed by a 2 × 4 factorial (environments × container colors) were arranged in a completely random pattern with 4 replications and 5 plants per plot, and a joint analysis of experiments was used to compare environments. The protected environment covered with low-density polyethylene film having 42-50 % of shading promoted higher initial growth of pepper plants, including early maturity, compared to the protected environment with 18-22 % of shading. The colored containers, namely, the brown container in a protected environment with 42-50 % shading and red container with 18-22 % shading formed plants with better growth and yield characteristics compared to the black container. The seedlings in the blue container had delayed flowering.

“…Costa et al [38] evaluated the growth parameters of the tray seedlings, as well as the growth and production of plants in pepper pots in greenhouses with three different types of shading-transparent low-density polyethylene and reflective aluminized screen under the film, black filament with 50% shade, and aluminized screen-with better yields being obtained with the first method.…”

Compatibility between Crops and Solar Panels: An Overview from Shading Systems

et al. 2018

View full text Add to dashboard Cite

The use of alternative energy in agricultural production is desired by many researchers, especially for protected crops that are grown in greenhouses with photovoltaic panels on the roofs. These panels allow for the passage of varying levels of sunlight according to the needs of each type of crop. In this way, sustainable and more economic energy can be generated than that offered by fossil fuels. The objective of this work is to review the literature regarding the applications of selective shading systems with crops, highlighting the use of photovoltaic panels. In this work, shading systems have been classified as bleaching, mesh, screens, and photovoltaic modules. The search was conducted using Web of Science Core Collection and Scopus until February 2018. In total, 113 articles from scientific journals and related conferences were selected. The most important authors of this topic are “Yano A” and “Abdel-Ghany AM”, and regarding the number of documents cited, the most important journal is Biosystems Engineering. The year 2017 had the most publications, with a total of 20, followed by 2015 with 14. The use of shading systems, especially of photovoltaic panels, requires more crop-specific research to determine the optimum percentage of panels that does not reduce agricultural production.
