Resumo: | Green areas have been expanding in cities with the proliferation of green areas at many sites (residential condominium gardens, soccer fields, golf courses etc.). Unfortunately, the water resources are limited and are not enough to attend all users simultaneously. Therefore, the rational use of water becomes necessary, mainly for irrigation purposes. This work had the main objective of evaluating the effect of water depths application, according to different reposition of the grass (Paspalum notatum) reference evapotranspiration (ETo) (40, 60, 80 and 100%), on grass dry matter production, aiming to obtain the minimum water depth necessary to maintain the visual quality of grass with water and energy savings. After each grass cutting, dry matter production was evaluated, allowing the determination of water use efficiency (WUE). Grass visual quality was evaluated by means of applying a questionnaire, using 16 evaluates. The models were chosen using the t-test, with level of probability up to 15% in the determination coefficient (R2). The results indicate that the dry matter production and the visual quality of the grass were not affected by the different water depths applied in the coldest months (July and August). A water depth of 40% ETo was recommended in July. For the other months, the water depth of 80% of ETo was recommended. |

Os recursos hídricos são limitados e nem sempre suficientes para atender a todos os usuários simultaneamente. Portanto, torna-se necessária a utilização racional da água para irrigação. Neste trabalho, objetivou-se avaliar o efeito da aplicação das lâminas de água correspondentes a 40, 60, 80 e 100% da ETo sobre a produção de matéria seca (MS) da grama-batatais, visando obter a lâmina mínima de água que preserve a qualidade visual, com economia de água e energia. A aparência do gramado foi avaliada por meio da aplicação de um questionário a 16 avaliadores. Após cada corte, avaliou-se a produção de MS, determinando a eficiência do uso da água (EUA). Os modelos foram escolhidos utilizando-se o teste t, com nível de até 15% de probabilidade no coeficiente de determinação (R2). Concluiu-se que a produção de MS e a qualidade visual da grama-batatais não foram afetadas pelas diferentes lâminas de água aplicadas nos meses mais frios. Para a grama-batatais, recomenda-se a lâmina de 40% da ETo no mês de julho; nos outros meses, recomenda-se a lâmina de 80% da ETo.Universidade Estadual De Maringá2009-11-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiondeterminaçãoapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciTechnol/article/view/157610.4025/actascitechnol.v32i1.1576Acta Scientiarum.
