Resumo: | This experiment was conducted in Lavras - state of Minas Gerais (MG), Brazil, in a protected environment, and aims to estimate the irrigation depths that maximize productivity and economic returns in the cultivation of asparagus bean and analyze the economic viability of irrigation management. The experimental delineation was randomized blocks with five treatments and four replications. The treatments consisted of five drip irrigation depths: 40, 70, 100, 130 and 160% of water replacement depth up to field capacity. The depths of water that maximize productivity and economic returns were obtained from the regression model adjusted to productivity data, cost of product relations and water cost. The economic viability was achieved on the benefit/cost ratio basis. The depth with the maximum economic return was estimated in 434.4mm, with a productivity of 35,160.6kg ha-1, which is economically viable for the cultivation of asparagus bean, with a expected profitability of R$ 1.70 for every real invested. |

O delineamento experimental foi em blocos casualizados, com cinco tratamentos e quatro repetições. Os tratamentos constituíram-se de cinco lâminas de irrigação por gotejamento, sendo: 40; 70; 100; 130 e 160 % da lâmina de reposição de água até a capacidade de campo. As lâminas de água que maximizam a produtividade e o retorno econômico foram obtidas a partir do modelo de regressão em função de dados de produtividade, das relações de preço do produto e do custo da água. A viabilidade econômica foi obtida com base na relação benefício/custo. A lâmina de máximo retorno econômico foi estimada em 431,3 mm, com uma produtividade de 35.156,6 kg ha-1, que é viável economicamente para o cultivo do feijão-de-metro, com uma rentabilidade esperada de R$ 1,7 para cada real investido.Associação Brasileira de Engenharia Agrícola2017-06-06T19:49:12Z2017-06-06T19:49:12Z2013-07info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfSILVA, W.
