“…The yield in the present work tended to be greater when the deficit was applied at maturation and lower when applied to the fruit set stage, even with no difference between the yields considering only RDI, confirming the results from Santos et al (2014b), who applied a RDI of 50% of ETc at the fruit set stage and observed a decreased in yield for two consecutive cycles.…”

“…This result indicates that the RDI applied to the fruit set and maturation stages is an option to use in mango for reduce the applied water depth while maintaining the yield and maintaining or increasing the water use efficiency. Similar results were found by Santos et al (2014b) with the application of RDI with 50% of ETc in 'Tommy Atkins' mango at fruit development and maturation stages, observing no yield reduction, which enabled to maintain the water use efficiency with RDI applied at fruit development stage (Stage II) and increased water use efficiency in the fruit maturation stage.…”

“…The total yield and fruit number of each treatment were compared. The water use efficiency was found according to Silva et al (2009), andSantos et al (2014b) , and 136 (Stage III) days after flowering, both at 8:00 and 14:00h because the contrasting conditions, constituting four evaluations and two time-of-day. Gas exchange evaluations were performed in the central part of intact leaves from the middle of the terminal branch, at a medium height of the tree canopy on the plant side exposed to the sun.…”

-The objective of this work was to evaluate the gas exchange, leaf temperature, yield and water use efficiency in 'Tommy Atkins' mango under irrigation deficit strategies. The experimental design was randomized block, with seven treatments with regulated deficit irrigation (RDI) under micro-spray and five treatments with partial root-zone drying (PRD) under drip irrigation. The treatments on RDI consisted of application of 100, 75 and 50% of ETc at the stages S1 (beginning of flowering to fruit set) S2 (fruit development) and S3 (fruit physiological maturation). The treatments on PRD consisted of application of 100, 80, 60 and 40% of ETc, in the same three stages, alternating the irrigation side every 15 days. The regulated deficit irrigation causes less negative interference in gas exchange than the partial root-zone drying, and the climate factors affect the gas exchange and leaf temperature of 'Tommy Atkins' mango more than the regulated deficit irrigation. The partial root-zone drying irrigation with 60 and 40% of ETc causes a decrease in the 'Tommy Atkins' mango yield. The regulated deficit irrigation up to 50% of ETc, applied at the fruit maturation stage, maintain the yield and water use efficiency.Keywords: Water deficit. Irrigation management. Mangifera indica.

PARÂMETROS FISIOLÓGICOS E PRODUTIVOS EM MANGUEIRAS 'TOMMY ATKINS' SOB ESTRATÉGIAS DE DÉFICIT DE IRRIGAÇÃORESUMO -Objetivou-se com este trabalho avaliar as trocas gasosas, temperatura foliar, produtividade e eficiência de uso da água em mangueira "Tommy Atkins" sob irrigação com déficit. O delineamento experimental foi em bloco casualizado, com sete tratamentos para a irrigação com déficit controlado (RDI) sob microaspersão e com cinco tratamentos para a irrigação lateralmente alternada (PRD) sob gotejamento. No manejo RDI os tratamentos consistiram da aplicação de 100, 75 e 50% da ETc nas fases F1 (início da floração até o pegamento dos frutos), F2 (desenvolvimento do fruto), e F3 (maturação fisiológica do fruto). No manejo pelo PRD os tratamentos consistiram da aplicação de 100, 80, 60 e 40% da ETc nas três fases com alternância do lado irrigado de 15 dias. Verificou-se que a irrigação com déficit controlado causa menos interferências negativas nas trocas gasosas que a irrigação lateralmente alternada e as trocas gasosas e temperatura foliar da mangueira "Tommy Atkins" sofrem maiores influências de elementos do clima que da irrigação com déficit controlado. A irrigação lateralmente alternada com 60 e 40% da ETc ocasiona queda na produção da mangueira "Tommy Atkins". Irrigação com déficit controlado com até 50% da ETc aplicados na fase de maturação do fruto mantem a produtividade e a eficiência de uso da água.Palavras-chaves: Déficit hídrico. Manejo da irrigação.

“…The daily irrigation time used for each treatment was used according to COTRIM et al (2011), SANTOS et al (2014a, NEVES et al (2013) and SANTOS & MARTINEZ (2013), considering 0.90 as the application efficiency. These determinations were performed using IRRIMANGA software, computational tool to obtain evapotranspiration and calculation of irrigation time for mango crop management (SANTOS, 2012).…”

ABSTRACT:The objective of this study was to evaluate the nutrient contents in 'Tommy Atkins' mango leaves at the flowering and fruiting stages under different strategies to reduce irrigation levels during flower induction. Five irrigation level reduction strategies, based on crop evapotranspiration (ETc) were used in the plots: T1 (0% ETc), T2 (25% ETc), T3 (50% ETc), T4 (75% ETc) and T5 (100% ETc); two production cycles in the split-plots; and in two development stages, flowering and harvest, in the split-split plots. The content of N, P, K, Ca, Mg, and S, as well as B, Cu, Fe, Mn, Zn, and Na was determined and leaf chlorophyll index was measured during the second cycle. The content of P, K, Mg, and Cu in the 'Tommy Atkins' mango trees leaves varied according to phases and cycles, regardless of the strategies to reduce irrigation levels in floral induction. The contents of N, Ca, B, Fe, Mn, and Na varied with stages and with the production cycles, in an independent manner. Foliar N contents were above the sufficiency range at the different development stages and cycles evaluated. The indices of a, b, and total chlorophyll varied independent of reading time. The nutrient contents with lower mobility in the plant, Ca, B, Fe and Mn increase in 'Tommy Atkins' mango trees leaves from flowering to fruiting, with the return of irrigation at 100% crop evapotranspiration, while the levels of N, P, K and Mg, nutrients with high mobility in plant decrease.
