“…Some authors have studied the infIuence of plastic covers on vegetable and fruit production. Holeman et al (2017) reported differences in cherry tomato yield in greenhouses with different plastic covers. Plastic anti-UV film and thermo-refIective shading screen showed lower fruit quantity and average fruit yield than diffusive plastic film.…”

Hydroponic technologies have increased the cultivated area under greenhouses covered with UV filter polyethylene film. However, there is a concern about the antioxidant contents of lettuces produced under these systems. In this study, it was compared to the antioxidant contents of green and red leaf lettuces produced in two hydroponic systems in a greenhouse, against the ones produced with the conventional cultivation system by Colombian farmers. The antioxidant analysis revealed significant statistical differences for DPPH and Anthocyanin analyses (P=0) versus all other culture systems. The best results were obtained in the conventional cultivation. Red lettuce obtained the highest value of FRAP (655.3±82.6 mgAAE 100g-1), ABTS (17.8±6.9 mmolTE 100g-1), total phenols (680.2±69.3 mgGAE 100g-1) and anthocyanin (126.2±6.9 mgC3G 100g-1). Green lettuce exhibited the most antioxidant activity of DPPH (20.7±5.6 mmolTE 100g-1). These results suggest a detrimental effect of the greenhouse covered with UV filter polyethylene film in the antioxidant production of lettuce. Finally, red leaf lettuce showed better antioxidant capacity independent of the cultivation system.

“…Según Bhandari et al (2021) esto se debe a que las condiciones climáticas son un factor que afectan la calidad y rendimiento en la producción del tomate. Sin embargo, dicha situación pudiera ser manejada de mejor forma en el invernadero, favoreciendo las condiciones para el crecimiento de las plantas a través del control parcial de las variables climáticas (Holcman et al, 2017).…”

La diversidad ambiental de México ha permitido el desarrollo de diferentes formas silvestres y cultivadas de tomate cuyos frutos se comercializan local y regionalmente en diferentes estados del país. Este trabajo se realizó con el objetivo fue evaluar la calidad agronómica de 23 poblaciones de tomate nativo de México y dos comerciales como testigo, establecidas en condiciones de invernadero y campo abierto. Esta investigación se hizo en el Colegio de Postgraduados, Campus Montecillo, Texcoco, Estado de México, de febrero a junio de 2018. Las poblaciones nativas de tomate se obtuvieron del centro y sur de México; donde se evaluaron variables agronómicas y calidad de fruta. Los resultados muestran que las poblaciones de tomate fueron más afectadas por el factor variedad, en las variables: número de frutos, diámetro polar y ecuatorial, y número de lóculos; el ambiente produjo el mayor efecto en: altura de planta, número de hojas, peso de fruto, rendimiento y grosor de pericarpio. La interacción de variedad por ambiente afectó al número de frutos en mayor proporción. Cabe destacar que bajo condiciones protegidas y de campo abierto el genotipo nativo G3 generó el mayor rendimiento, con 4.4 kg/planta en invernadero y 2.8 kg/planta en campo. El rendimiento promedio en invernadero fue mayor en un 131 % comparado con el de campo abierto. En conclusión, se pudo observar que los materiales evaluados se adaptaron bien a un sistema de producción bajo condiciones protegidas, ocasionando que el rendimiento y la calidad de fruta incrementara.

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

et al. 2018

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.
