“…On the other hand, total cotton production reached 978 tons, an amount 320% higher than that of the 2015/2016 season. This is a response to the irrigated cotton area increase and because of the use of irrigation technology, as it is stated by Almeida et al (2015), the use of irrigation and soil cover increase the graviola production in Brazil, and yields of beans and corn in 54,5% and 237,3% (Brito et al, 2012). Table 2 shows the details of cotton production from the 2015/2016 campaign to the estimate for 2019/2020.…”

The North of Minas Gerais, a large inland state in southeastern Brazil, is going through the worst drought of the last 80 years, only compared with the drought that occurred in the 1930s, when there was general devastation in the agricultural and livestock sector. Nevertheless, the cotton crop continues to stand out in the region as one of the few agricultural alternatives capable of generating income and employment due to its characteristic resistance to the effects of drought, which is not the case with other traditional crops. To this end, the Cooperativa dos Produtores Rurais de Catuti Ltda ‐ COOPERCAT (Cooperative of Rural Producers of Catuti) installed eight “Demonstration Units” (DUs) of cotton under supplemental irrigation through rainwater capture in the municipalities of Catuti, Mato Verde, Monte Azul, and Pai Pedro. This study aims to demonstrate that the adaptation of cotton production systems through the “Supplemental Irrigation” method in critical periods provides and guarantees family farmers sustainable cotton production and, on the other hand, to evaluate a production model suitable to the climatic reality of Northern Minas. Since the implementation of this technology, cotton fiber production has increased by 72% from 2015 to date in a 19% smaller area, and total cotton production increased by 58%. As of 2022, cotton producers continue to use this supplemental irrigation methodology, demonstrating that the technology is viable, impacts cotton production, and is effective as a resilience measure to climate change and drought. In addition, this technology proves to be in line with Brazilian public policies, adds value to cotton production, addresses food security, and acts as a model for irrigation initiatives in Minas Gerais and other areas of Brazil.

“…The cultivation of sweet potatoes is one of the most important vegetable crop for family farmers in the micro-region of Catolé do Rocha-PB and your production tuberous root is negatively affected by water stress, with greater intensity in semiarid regions, according verified by Saqib et al (2017), after irrigating the crop with water blades equivalent to 60, 80, 100, and 120% of its water requirement. Almeida et al (2015) and Cui et al (2020) concluded that the water deficit inhibits crop photosynthesis, growth and production. This situation expresses the dependence of agricultural production systems on irrigation, in the semiarid world, and requires the adoption of water management strategies in order to obtain sustainable agricultural yields to guarantee food availability, given the growing global concern (SOUZA et al, 2016;DELZARI et al, 2017;EL-FOTOH et al, 2019).…”

The objective was to evaluate the effect of the reduction in the irrigation blades under silicate fertilization via soil on growth, branch emission, production of fresh phytomass of aerial part, yield of marketable tuberous roots, and agricultural water use efficiency by plants of the sweet-potato variety Campina, with purple skin. The treatments were arranged in subdivided plots, distributed into randomized blocks, using a 2x5 factorial scheme with three repetitions, totaling 30 experimental units. The plots were two irrigation blades of 100 and 50% of the crop evapotranspiration â€“ (ETc) and the subplots corresponded to the silicon doses of 0.0, 0.5, 1.0, 1.5, and 2.0 g plant-1. At the end of the experiment, the following variables were evaluated: stem diameter, branch emission, fresh phytomass of aerial part, phytomass of marketable tuberous roots, yield, and water use efficiency by plants. According to the results, the reduction from 100 to 50% of the ETc caused inhibition of growth, production of fresh phytomass of aerial part, and yield of marketable tuberous roots. The crop revealed to be more sensitive to water stress regarding yield than regarding growth or biomass formation by the aerial part and marketable tuberous roots.

“…Among the soursops exploited in Brazil, the cultivar 'Morada Nova' has stood out due to its easy adaptation to the most diverse types of soil and for being able to produce more than 40 kg of pulp per year. Currently, the Northeast region in Brazil stands out as the largest producer of this fruit crop, especially the states of Bahia, Alagoas, Ceará, Paraíba and Pernambuco (São José et al, 2014;Almeida et al, 2015). This region has scarce rainfall and high evaporation rates, naturally causing a water deficit which limits the growth and production of crops under natural conditions, i.e., rational agricultural exploitation is only possible using irrigation; however, the waters available for irrigation in these regions are not always of good quality, causing the use of saline waters to become a reality, characterizing a problem that affects the economy of the region, the society and the environment (Medeiros et al, 2012;Nascimento et al, 2017).…”

Effects of saline water and exogenous application of hydrogen peroxide (H2O2) on Soursop (Annona muricata L.) at vegetative stage

et al. 2019

Soursop is a fruit of great socioeconomic importance for the northeastern region of Brazil. However, the quantitative and qualitative limitation of the water resources of this region has reduced its production. The objective of this study was to evaluate the growth of ‘Morada Nova’ soursop plants irrigated with saline water and subjected to exogenous application of hydrogen peroxide through seed immersion and foliar spray. The study was conducted in plastic pots adapted as lysimeters, using a eutrophic Regolithic Neosol with sandy loam texture under greenhouse conditions. Treatments were distributed in randomized blocks, in a 4 x 4 factorial arrangement, corresponding to four levels of irrigation water electrical conductivity – ECw (0.7; 1.7; 2.7 and 3.7 dS m-1) and four concentrations of hydrogen peroxide – H2O2 (0, 25, 50 and 75 µM), with three replicates and one plant per plot. Foliar applications of H2O2 began 15 days after transplanting (DAT) and were carried out every 15 days at 17:00 h, after the sunset, by manually spraying the H2O2 solutions with a sprayer in such a way to completely wet the leaves (spraying the abaxial and adaxial faces). Treatment effects were evaluated based on plant height (PH), stem diameter (SD), number of leaves (NL) and leaf area (LA) at 60 and 90 DAT, and dry phytomass of leaves (LDP), stem (SDP), roots (RDP) and total (TDP) and leaf succulence (LS) at 90 DAT. Irrigation using water with estimated ECw of 1.55 dS m-1 caused acceptable mean reduction of 10% in soursop growth. Increasing concentrations of hydrogen peroxide did not attenuate the effects of salinity on plant height and leaf area during the vegetative stage. Hydrogen peroxide concentration of 20 µM led to higher leaf succulence in soursop plants.
