| description | This study aimed to test controlled levels of water deficiency in soil in mango trees, under microsprinkling irrigation, in semi-arid conditions, and to evaluate its effect in the productivity and fruits quality. The deficits were applied in the phases I, II and III of growth of the fruit, during the productive cycles of the mango tree in 2006 and 2007. The experiment in both cases was arranged in an entirely random design with 10 treatments and 3 repetitions, in the year I, and with 8 treatments and 3 repetitions in the year II. The values of soil water potential, of the treatments submitted to regulated deficit irrigation (RDI), were placed in the range of 0 to -0.011 MPa, showing that the soil humidity varied between the saturation and the field capacity, not characterizing deficit water condition. The average values of stem water potential (Ψstem) varied between -0.90 and -1.74 MPa, evidencing significant effect (p |

Este trabalho teve o objetivo de testar níveis controlados de deficiência de água no solo em mangueira irrigada por microaspersão, no semi-árido, e avaliar seu efeito na produtividade e qualidade dos frutos. Os déficits foram aplicados nas fases I, II e III de crescimento do fruto, durante os ciclos produtivos da cultura da mangueira, nos anos de 2006 e 2007. O delineamento experimental, em ambos os casos, foi o inteiramente casualizado, com dez tratamentos e três repetições, no ano I, e com oito tratamentos e três repetições, no ano II. Os valores de potencial de água no solo, dos tratamentos submetidos à irrigação com déficit regulado (RDI), situaram-se na faixa de 0 a -0,011 MPa mostrando que a umidade do solo variou entre a saturação e a capacidade de campo, não caracterizando condição de déficit hídrico. Os valores médios de potencial hídrico do ramo (Ψstem) variaram entre -0,90 e -1,74 MPa, mostrando efeito significativo apenas para T1 (sem irrigação), T7 e T8 (RDI com 30% da ETc nas fases II e III, respectivamente). Por meio da análise de variância, não foram constatadas diferenças significativas entre produtividade, número de frutos por planta e tamanho do fruto, em nenhum dos experimentos, o que indica a possibilidade de redução do uso de água na irrigação da cultura sem perdas significativas de produtividade e qualidade do fruto.</description><identifier>ISSN: 0100-6916</identifier><identifier>ISSN: 1809-4430</identifier><identifier>EISSN: 0100-6916</identifier><identifier>DOI: 10.1590/S0100-69162011000600003</identifier><language>eng</language><publisher>Associação Brasileira de Engenharia Agrícola</publisher><subject>AGRICULTURAL ENGINEERING</subject><ispartof>Engenharia Agrícola, 2011-12, Vol.31 (6), p.1052-1063</ispartof><rights>This work is licensed under a Creative Commons Attribution-NonCommercial 4.0 International License.</rights><lds50>peer_reviewed</lds50><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c345t-3c5267a517e77655d45890436b77db669d3a6a8f287ea2b5c4d0aec62aa6d81f3</citedby><cites>FETCH-LOGICAL-c345t-3c5267a517e77655d45890436b77db669d3a6a8f287ea2b5c4d0aec62aa6d81f3</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>230,314,778,782,862,883,27907,27908</link.rule.ids></links><search><creatorcontrib>Cotrim, Carlos E</creatorcontrib><creatorcontrib>Coelho Filho, Maurício A</creatorcontrib><creatorcontrib>Coelho, Eugênio F</creatorcontrib><creatorcontrib>Ramos, Márcio M</creatorcontrib><creatorcontrib>Cecon, Paulo R</creatorcontrib><title>Regulated deficit irrigation and tommy atkins mango orchard productivity under microsprinkling in brazilian semi arid</title><title>Engenharia Agrícola</title><addtitle>Eng.
