“…Thus, the bulbshaped wetted area of the treatment MSBP was formed under a little shaded area subjected to high evaporation rates, thus decreasing the soil water potential and water availability to plants. Similar results were found bySimões et al (2018) for Keitt mango trees, and bySimões et al…”

Mango production has been having a great economical expression in the Brazilian agriculture. However, the economic crisis and increased competitiveness of the international market required improvements in the crop efficiency for its sustainability. In this context, the objective of this work was to evaluate the effect of different irrigation system on the physiology and fruit yield and quality of Palmer mango trees in the semiarid conditions of the Lower Middle São Francisco Valley, Brazil. The experiment was carried out at the Agranvil Farm, in Petrolina, state of Pernambuco, Brazil, with harvests in July 2013 and October 2014. A randomized block statistical design was used, with four treatments replicated in 5 blocks, during two production cycles. The treatments consisted of four irrigation systems: one micro sprinkler under the plant canopy (MSPC); drip system with two lateral lines per plant row (DSLL); one micro sprinkler between plants (MSBP); and ring-shaped drip system around the plants (RSDS). All treatments provided a flow rate of 56 L h-1 plant-1. The physiological characteristics evaluated were: photosynthesis, stomatal conductance, leaf transpiration, and leaf temperature. Fruit yield, quantity, mean weight, volume, soluble solid content, titratable acidity (TA), density, and pulp firmness were evaluated after the harvest. The evaluated treatments presented significant differences for the physiological variables. The treatment DSLL provided higher number of fruits and fruit yield, and the treatment MSBP provided the lowest results for these variables.

“…The results in Figure 2 show that both excess and scarcity of water caused partial closure of the stomata, which is an essential mechanism for plant survival under different soil moisture conditions (Simões et al, 2018;Ghafari et al, 2020;Gupta et al, 2020;Li et al, 2020). The highest levels of photosynthesis (Figures 2A and D), stomatal conductance (Figures 2B and E) and transpiration (Figures 2 C and F) in the cultivation with the rootstock were estimated for irrigation of 107.4, 108.3, and 117.3% ETc in the first half of the year and 114.4, 117.5, and 112.0% in the second half of the year, respectively.…”

“…Insufficient as well as excessive water supply induces stomatal closure, thus avoiding the reduction in the water potential. However, this response negatively affects various physiological processes such as transpiration and photosynthesis, causing a reduction in fruit weight (Simões et al, 2018). Regarding production, there was interaction between the forms of cultivation and the production cycles (Figure 5).…”

Using nematode-resistant and/or -tolerant rootstock is a strategy that has maintained guava cultivation feasible in the irrigated perimeters of the Brazilian semi-arid region. The objective was to evaluate the production, gas exchange, and fruit quality of ‘Paluma’ guava with and without nematode-tolerant rootstock under different irrigation depths and production periods. The experimental design was randomized blocks, in the mixed 2 × 4 × 2 factorial scheme, corresponding to two forms of cultivation of ‘Paluma’ guava (without and with nematode-tolerant rootstock), four irrigation depths (60, 80, 100, and 120% of crop evapotranspiration - ETc), and two production periods, with four replicates. Guava plants were evaluated for physiological, production and post-harvest quality parameters. Gas exchange in ‘Paluma’ guava leaves was higher in the second production cycle, under irrigation depths above 100% ETc, not differing with the use of the rootstock. The use of the rootstock ‘BRS Guaraçá’ promotes a greater number of fruits and production with the increase of the irrigation depth, mainly in the second half of the year, with the increase of soluble solids and titratable acidity in the fruits.

“…Thus, the irrigation cycle with micro-sprinklers was not sufficient for the roots to develop throughout the wetted profile, since the irrigation amounts were the same and with a deficit. Simões et al (2018) evaluated the effect of the micro-sprinkler and drip-irrigation systems on the physiological, productive and qualitative traits of fruits of 'Keitt' mango tree at nine years old and found that drip irrigation is the most suitable system for its cultivation, in Vale do Submédio São Francisco, because it interferes positively with photosynthetic activity, stomatal conductance and yield.…”

“…The lower WUE in the micro-sprinkler system may be related to the form of water distribution in the soil, since the micro-sprinkler is located far from the plant trunk and part of the soil moistened by the irrigation system is exposed to solar radiation, which can increase evaporation losses and reduce water availability for the plant, as compared with drip irrigation (Simões et al, 2018). In addition, the drip irrigation system allows less evaporation of water from the soil when compared with the micro-sprinkler, especially in regions with strong winds that coincide with the period when irrigation is necessary, as is the case in the evaluated region (Figure 1).…”

The increasing water demand of crops in response to climate change; the prospect of expanded irrigated areas; the population growth; and competition with multiple uses of water affect the availability of water resources for agriculture. Thus, measures are required that involve the adoption of irrigation-management strategies able to increase water savings without compromising crop yield, especially in semi-arid conditions, where water resources are limited, and in large-scale commercial cultivation such as in 'Tommy Atkins' and 'Palmer' mango, the second most widely grown irrigated fruit crop. The objective of this study was to examine the influence of irrigation systems (drip and micro-sprinkler) and deficit-irrigation strategies on the yield and water use efficiency (WUE) of 'Tommy Atkins' and 'Palmer' mango trees. The study was developed through two experiments conducted in the Irrigated Perimeter of Ceraíma, located in municipality of Guanambi - BA, Brazil. Two trials were carried out in a completely randomized design. For the 'Tommy Atkins' cultivar, 12 strategies were tested, involving regulated deficit irrigation (RDI) by micro-sprinkler irrigation and partial rootzone drying (PRD) by drip, in three production cycles. For ‘Palmer’ mango, 10 irrigation strategies were evaluated under the same previously described conditions, in only one production cycle. The reduction in water application in RDI was 25 and 50% of the crop evapotranspiration (ETc); and, in PRD, 20, 40 and 60% ETc. ‘Tommy Atkins’ mango achieved higher yields under micro-sprinkler irrigation with full irrigation and in the strategies involving the application of 50 and 75% ETc in stages II and III. These two strategies also provided greater WUE, along with PRD40. Water use efficiency was lower in the third evaluation cycle when compared with the first. ‘Palmer’ mango showed higher yields and WUE under drip irrigation, with the best yields achieved with full irrigation and in the strategies of PRD100, 80%, 60% and RDI with 50% ETc in stage III. The best WUE was obtained in PRD with 60 and 40% ETc.
