“…The results of this study differ from those reported by COTRIM et al (2011),which no significant differences at 5% probability on 'Tommy Atkins' mango tree productivity submitted to regulated deficit irrigation between treatments with 100, 80, 60, 40 and 30% of ETc under micro sprinkler systems and drip. The authors explained the results by rise of the water level in the study area, which prevented the effect of different irrigation depths.…”

ABSTRACT:With the limited availability of water in semi-arid regions, it is necessary that irrigation is accurate and there is high water use efficiency.This study aimed to evaluate the regulated deficit irrigation (RDI) and partial rootzone drying (PRD) in yield, water use efficiency and gas exchange of 'Tommy Atkins' mango tree in semi-arid conditions. The experimental design was a randomized block with seven treatments for RDI under micro sprinkler and five treatments for the PRD under drip. Treatments were applied in phases PI -early blooming to early fruit expansion, PII -early expansion to early physiologic ripening and in phase III -physiologic ripening of fruits, with application of the RDI of 100, 75 and 50 % of ETc in different combinations of phases and application of PRD 100, 80, 60 and 40 % of ETc in three phases with the partial rootzone druing at 15 days. Photosynthesis, carboxylation efficiency and quantum efficiency of photosynthesis are lower in PRD 40% ETc at 8 a.m. compared to full irrigation and PRD 80 % of ETc. Phases of expansion and fruit ripening are more appropriate for application of RDI with 50 % and 75% of ETc without loss to the crop yield of 'Tommy Atkins' mango tree and greater water use efficiency. The strategy of partial rootzone drying, PRD, every 15 days with 40 % of ETc, provides greater WUE.

“…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.

“…Regulated deficit irrigation has been purposed in several crops, such as mango (Spreer et al, 2007;Silva et al, 2009;Cotrim et al, 2011Santos et al, 2014), pear (Marsal et al, 2008), grapevine (McCarthy, 2000;Ferreyra et al, 2002), peach (Gelly et al, 2004), loquat (Cuervas et al, 2007), melon (Fabeiro et al, 2002), olive (Iniesta et al, 2009), tomato (Savić et al, 2008), garlic (Cortés et al, 2003), onion (Olalla et al, 2004), beet (Fabeiro et al, 2003), bean and watermelon (González et al, 2009). These studies show water and energy saving, fruit quality improvement and yield increase.…”

A B S T R A C TThe aim of this study was to evaluate the 'Tommy Atkins' mango yield and photosynthesis in regulated deficit irrigation (RDI) in semiarid conditions of Bahia, Brazil. The experimental design was a randomized block with five treatments and six replications: T1, irrigation supplying 100% crop evapotranspiration (ETc) in phases: I (beginning of flowering to early fruit growth), II (start of expansion until early physiological maturity) and phase III (physiologically mature fruits); T2, RDI with 50% ETc in phase I; T3, RDI with 50% ETc in phase II; T4, RDI with 50% ETc in phase III; T5, No irrigation. The soil water deficit causes a reduction in photosynthesis. Mango yield in treatment 4 was approximately 5.5 and 2 times greater than in treatments 5 and 2, respectively. The use of RDI with 50% water depth reduction applied in the third phase of 'Tommy Atkins' mango fruit development was efficient. The use of RDI with 50% ETc in the third phase of fruit development provided the best yield of 'Tommy Atkins' mango for the 350 g weight class.Produtividade e fotossíntese da mangueira 'Tommy Atkins' sob déficit hídrico em região semiárida da Bahia R E S U M O Objetivou-se, com este trabalho, avaliar a produtividade e a fotossíntese da mangueira 'Tommy Atkins' sob irrigação com déficit controlado (RDI) em condições semiáridas do sudoeste da Bahia. O delineamento experimental foi em blocos casualizados com cinco tratamentos e seis repetições: T1 -Irrigação suprindo 100% da ETc nas fases: I (do início da floração até o início da expansão dos frutos), II (início da expansão até início da maturação fisiológica) e na fase III (maturação fisiológica dos frutos); T2 -RDI com 50% da ETc na fase I; T3 -RDI com 50% da ETc na fase II; T4 -RDI com 50% da ETc na fase III; T5 -Sem irrigação. O déficit hídrico no solo ocasiona redução na taxa fotossintética. A produtividade no tratamento 4 foi aproximadamente 5,5 e duas vezes maior que nos tratamentos 5 e 2, respectivamente, enquanto o uso da RDI com redução de 50% da lâmina de irrigação aplicada na terceira fase de desenvolvimento dos frutos de mangueira 'Tommy Atkins' foi eficiente; já o uso da RDI com 50% da ETc na terceira fase de desenvolvimento do fruto, proporciona melhores produtividades de mangueira 'Tommy Atkins' para a classe de peso 350 g.
