Resumo: Proper irrigation management is important both to enable adequate water supply and to minimize problems with diseases, nutrient leaching and unnecessary water and power wastes. Thus, this study aimed at improving irrigation management in greenhouses. For that reason, we assessed the effect of various water tensions on yield performance of crisphead lettuce, Raider-Plus cv. , grown with mulching. The experiment was conducted in greenhouse at the Federal University of Lavras. Treatments constituted five different soil water tensions, namely 12, 25, 35, 45, and 70 kPa. The results showed that irrigation must be carried out at water soil tension of around 12 kPa to reach satisfying commercial values for both total and commercial yield, 66 and 50 t ha-1, as well as keeping good vegetable quality. At this tension, total water consumption was of 167.25 mm. The water use efficiency demonstrated quadratic response to treatments, with high water consumption efficiency found in intermediate treatments (35 and 45 kPa), achieving values of 579.87 and 471.71 kg ha -1mm-1, respectively.

Visando a definir critérios para o manejo da irrigação, este trabalho teve como objetivo avaliar o efeito de diferentes tensões de água no solo sobre o comportamento produtivo da alface-americana, cv. Raider-Plus, em ambiente protegido, com uso de mulching. O experimento foi conduzido em casa de vegetação na Universidade Federal de Lavras. Os tratamentos foram constituídos de cinco tensões de água no solo: 12; 25; 35; 45 e 70 kPa. Os resultados permitiram concluir que, para a obtenção de valores máximos de produtividade total e comercial, 66 e 50 t ha-1, a reposição da lâmina evaporada deve ser realizada quando a tensão de água no solo atingir 12 kPa, representando consumo total de 167,25 mm. As variáveis altura de plantas e circunferência da cabeça comercial tiveram valores máximos alcançados quando se utilizou a tensão de 12 kPa. A eficiência no uso da água apresentou resposta quadrática aos tratamentos, sendo que a maior eficiência no consumo de água foi verificada nos tratamentos intermediários (35 e 45 kPa), atingindo valores de 579,87 e 471,71 kg ha -1mm-1, respectivamente.Associação Brasileira de Engenharia Agrícola2018-10-09T13:29:45Z2018-10-09T13:29:45Z2016info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfGEISENHOFF, L.
