Resumo: | Cultivation in protected environments allows for crop production in seasons that normally would not be suitable for open field production. This study sought to evaluate the variations in luminosity, air and soil temperature and relative humidity of the air in different environmental conditions during the winter and summer, in Cáceres-MT, using screens with mesh of 30, 40 and 50% shading, thermo-reflective screens with 30, 40 and 50% shading and an open field. The experimental design utilized consisted of randomized blocks with 10 replications, represented by 10 days of collection. It was observed that the screened environments reduced the minimum, average and maximum values of the luminosity and air temperature attributes, and resulted in an increase in relative humidity compared to the open field environment. The black screens with 40% and 50% shading and the 50% thermo-reflective screen presented greatest efficiency to reduce luminosity and air temperature. The screen with 50% shading was that which resulted in the greatest indices of relative humidity of the air among the treatments. |

Objetivou-se com este trabalho avaliar as variações de luminosidade, temperatura do ar e do solo e umidade relativa do ar, em diferentes ambientes de cultivo, no período seco e no chuvoso, em Cáceres-MT, utilizando telados com malhas de 30, 40 e 50% de sombreamento, telas termorefletoras com 30, 40 e 50% de sombreamento e uma área de campo aberto. O delineamento experimental utilizado foi o de blocos casualizados com 10 repetições, representadas por 10 dias de coleta. Foi observado que os ambientes telados reduziram os valores mínimos, médios e máximos dos atributos luminosidade e temperatura do ar e proporcionaram aumento na umidade relativa do ar, quando comparados com o ambiente campo aberto. Os telados com tela de sombreamento de 40 e 50% e tela termorefletora 50% apresentaram maior eficiência para a redução da luminosidade e da temperatura do ar. A tela de sombreamento 50% foi a que proporcionou maiores índices de umidade relativa do ar entre os tratamentos.Universidade Federal de Viçosa - UFV2014-02-21info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/32610.13083/reveng.v22i1.362Engineering in Agriculture; Vol. 22 No. 1 (2014); 33-42Revista Engenharia na Agricultura - REVENG; v. 22 n. 1 (2014); 33-422175-68131414-398410.13083/reveng.v22i1reponame:Engenharia na Agriculturainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/reveng/article/view/326/246Rampazzo, RenatoJunior, Santino SeabraMoitinho Nunes, Maria CândidaAlves da Silva Neves, Sandra MaraFerreira, Regiane Fátimainfo:eu-repo/semantics/openAccess2023-01-19T13:21:23Zoai:ojs.periodicos.ufv.br:article/326Revistahttps://periodicos.ufv.br/revengPUBhttps://periodicos.ufv.br/reveng/oairevistaengenharianagricultura@gmail.com||andrerosa@ufv.br||tramitacao.reveng@gmail.com|| reveng@ufv.br2175-68131414-3984opendoar:2023-01-19T13:21:23Engenharia na Agricultura - Universidade Federal de Viçosa (UFV)false |

Cultivation in protected environments allows for crop production in seasons that normally would not be suitable for open field production. This study sought to evaluate the variations in luminosity, air and soil temperature and relative humidity of the air in different environmental conditions during the winter and summer, in Cáceres-MT, using screens with mesh of 30, 40 and 50% shading, thermo-reflective screens with 30, 40 and 50% shading and an open field. The experimental design utilized consisted of randomized blocks with 10 replications, represented by 10 days of collection. It was observed that the screened environments reduced the minimum, average and maximum values of the luminosity and air temperature attributes, and resulted in an increase in relative humidity compared to the open field environment. The black screens with 40% and 50% shading and the 50% thermo-reflective screen presented greatest efficiency to reduce luminosity and air temperature. The screen with 50% shading was that which resulted in the greatest indices of relative humidity of the air among the treatments. |
