Irrigação Lateralmente Alternada Em Lima Ácida 'Tahiti' Na Região Norte De Minas Gerais

Abstract: RESUMOAs condições hídricas do solo e clima alteram as condições hídricas e fisiológicas das plantas, que influenciam o desenvolvimento e a produção. Objetivou-se com este estudo avaliar características fisiológicas, estado nutricional e produtividade em lima ácida 'Tahiti' com irrigação lateralmente alternada (partial rootzone drying -PRD). Nove tratamentos foram constituídos por diferentes reposições de lâmina de água aplicada, conforme a demanda evapotranspirométrica da cultura (ETc) e diferentes frequência… Show more

“…The area with localized irrigation showed higher values than those of center pivot in 2017 ( Figure 2B), due to its demand in the Southeast region, mainly in coffee crops (Assis et al, 2014), which grew by 37% in the number of trees planted between 2006 and 2017, and citrus (Palaretti et al, 2011;Santos et al, 2016) ( Figure 3B). In addition, the lower demand for water and inputs caused localized irrigation to expand to areas previously occupied by other irrigation systems (ABIMAQ, 2018).…”

“…Although several studies have been conducted on the PRD technique, there are still knowledge gaps for different types of soil, climate and crops, to determine the feasibility of the PRD technique to farmers 17 , 18 , especially for some fruit trees, such as papaya 10 , 13 , 19 . Few studies have considered PRD techniques in papaya plants under controlled conditions (i.e., under greenhouse condition 9 , 10 ), while PRD studies under papaya field conditions have just recently started 10 , 13 , 19 , 20 .…”

“…Algumas das estratégias de irrigação que proporcionam manutenção da produtividade com redução da quantidade de água aplicada é a irrigação com déficit hídrico controlado (Regulated deficit irrigation -RDI) (CHAI et al, 2016) ou a irrigação lateralmente alternada, também conhecida como secamento parcial de raízes (Partial rootzone drying -PRD) (GOTUR et al, 2018). Em condições de semiárido brasileiro, a irrigação com déficit tem sido objeto de estudo em várias culturas, em lima ácida (SAMPAIO et al, 2014;SANTOS et al, 2016), em mangueira (SANTOS et al, 2014;SRIKASETSARAKUL et al, 2015;SANTOS et al, 2016;COTRIM et al, 2017), em pimentão (ROCHA et al, 2018) e em bananeira (SANTOS et al, 2017).…”
