Effects of water deficit in two phenological stages on production of japanese cucumber cultived in greenhouse

Abstract: ABSTRACT:The experiment was performed in the experimental area of the Engineering Department Federal University of Lavras, Minas Gerais State, Brazil. It aimed at identifying the adequate irrigation management of the greenhouse-cultivated Japanese cucumber (Cucumis sativus L.). complete randomized design, with four levels of soil water potential (15; 30; 60 e 120 kPa) at two phenological phases (vegetative and reproductive), and 5 replications. Overall, the results showed decrease of yield according to increas… Show more

“…The regulated deficit irrigation (RDI) and partial root-zone drying (PRD) or controlled alternate partial root-zone irrigation, are among the deficit irrigation techniques that has increasing water use efficiency in some crops. (BASSOI et al, 2011;ROMERO-CONDE et al, 2014;SAMPAIO et al, 2014;GHRAB et al, 2014).…”

“…McCarthy et al (2000) points out that the PRD is based on biochemical responses of plants to achieve a balance between vegetative and reproductive development through water stress, as a result, there is a significant improvement in production per unit of irrigation water applied. The irrigation should be performed before the water availability in the soil is reduced to levels that alter the metabolism of the plant to ensure the crop production (Oliveira et al, 2011). The use of different irrigation strategies and systems cause changes in soil water conditions that, associated with the climate, may influence the plant water status, with variations in leaf temperature and gas exchange, which directly influence growth, development and crop production.…”

“…On the other hand, the irrigation management based on PRD, also known in Brazil as irrigation with partially drying in the root area (SAMPAIO et al, 2010), consists in switching the side of the plant to be irrigated for 10 to 14 days, between phonological stages of fruit set and harvest. To ensure crop production, irrigation should be carried out before the water availability in the soil was reduced to levels that alter the metabolism of the plant, leading to productivity reduction (OLIVEIRA et al, 2011).…”

“…O cultivo de hortaliças em ambiente protegido e o manejo da irrigação com déficit hídrico são tecnologias bastante pesquisadas e difundidas atualmente com diferentes culturas (BILIBIO et al, 2010;OLIVEIRA et al, 2011). No entanto, estudos sobre as respostas produtivas e qualitativas do meloeiro a imposição de déficit hídrico em fases especificas de desenvolvimento são escassos no Brasil.…”

“…A autora atribuiu o fato ao curto período de tempo em que as plantas estiveram submetidas aos tratamentos, 24 dias. Todavia, Oliveira et al (2011) e Carvalho et al (2012, quando aplicaram diferentes tensões de água no solo durante a fase vegetativa do pepino japonês e da ervilha, respectivamente, verificaram que houve diferença estatística significativa entre os tratamentos, para os parâmetros analisados. Na Tabela 4 é apresentado o resumo da análise de variância para as variáveis, produtividade, comprimento e diâmetro dos frutos, sólidos solúveis totais, e firmeza da polpa do fruto em função da tensão de água no solo aplicada durante a fase reprodutiva (experimento II) da cultura.…”
