“…The results obtained here indicate that effluent from treated domestic sewage has potential to be used to irrigate prickly pear under semi-arid conditions and is a low-cost water source which reduces impacts on the environment. This same finding has also been reported for corn (COSTA et al, 2014), cowpea (REBOUÇAS et al, 2010, rice (BRITO et al, 2014) and sunflower (ALVES et al, 2014).…”

This study aimed to evaluate, in the second cycle, the growth and production of ‘Orelha-de-elefante Mexicana’ prickly pear (Opuntia sp.) under complementary irrigation with treated domestic sewage. The experiment was carried out in the Milagre Settlement, municipality of Apodi-RN, Brazil, from June 2016 to February 2017. Five treatments were evaluated, corresponding to four irrigation frequencies (2.3, 7.0, 14.0 and 21.0 days) to apply an effluent depth of 3.5 mm, and the control, rainfed cultivation (without irrigation). The experimental design was randomized blocks, with four replicates. After preliminary-primary treatment, the domestic sewage showed acceptable chemical and physical characteristics for fertigation under the conditions adopted in the prickly pear cultivation. 234 days after the 1st cut in the plants, the following morphometric characteristics were measured: plant height and length, width, perimeter, thickness and number of primary and secondary cladodes, and biomass accumulation. Complementary irrigation with treated domestic sewage effluent applied at intervals of 2.3, 7.0, 14.0 and 21.0 days allowed satisfactory growth and production of ‘Orelha-de-elefante Mexicana’ prickly pear; without irrigation, its development was substantially hampered during the dry period. Complementary irrigation with 3.5 mm of domestic sewage effluent applied at intervals of 2.3, 7.0 and 14.0 days led to highest growth and biomass accumulation in ‘Orelha-de-elefante Mexicana’ prickly pear.

“…The treatments consisted in five dilutions of TGW in WW: T1-100% WW plus 0% TGW; T2-75% WW plus 25% TGW; T3-50% WW plus 50% TGW; T4-25% WW plus 75% TGW and T5-0% WW plus 100% TGW. Gray water dilutions are recommended to reduce salt concentration and to identify the most adequate dilution to culture development (Brito, 2014;Medeiros et al, 2015).…”

The present work aimed to analyze the effects of the application of dilutions of treated gray water (TGW) in well water (WW) on growth and production of millet cv. Ceará (Pennisetum glaucum). The experiment was carried out in a greenhouse, on the department of agronomic and forestry sciences, at the Federal Rural University of the Semi-Arid (UFERSA), Mossoró, RN, Brazil. The experimental design was randomized blocks with five treatments and six replications, totaling thirty plots. The experiment was carried out in vases with volume of 25L containing four plants per vase. The treatments consisted in five dilutions of TGW in WW: T1—100% WW plus 0% TGW; T2—75% WW plus 25% TGW; T3—50% WW plus 50% TGW; T4—25% WW plus 75% TGW and T5—0% WW plus 100% TGW. During the experiment it was analyzed the attributes of plant height, number of tillers, number of leaves, stem diameter and total fresh and dry matters. With the results, it was observed that the exclusive irrigation with TGW (T5) promoted better millet development. As the concentrations of TGW increased in dilutions, also increased plant height, number of leaves and tillers. The rise in the number of leaves is associated to the rise in height and tillers, and those are associated to the rise in stem diameter and fresh matter, resulting in better accumulations of dry matter and showing the viability of gray water use to improve forage production and increasing potable water availability to multiple uses.

“…No que diz respeito ao aporte nutricional, em plantas de arroz vermelho irrigada com água residuária doméstica, Brito et al (2014) verificaram um aumento significativo na concentração de todos os nutrientes avaliados com o aumento da concentração de água residuária aplicada (Figura 8). Estes resultados mostram que as plantas absorvem grandes quantidade de nutrientes oriundos das águas residuárias.…”

Agricultura irrigada no Brasil: recursos hídricos e sustentabilidade

2022

View full text Add to dashboard Cite

A demanda global por produtos agropecuários não deixa de crescer e a expectativa de uma população mundial de cerca de 9,8 bilhões de pessoas em 2050 exige um planejamento relacionado a oferta de alimentos. Neste cenário, a agricultura irrigada apresenta importante papel para a agricultura no país, seja para aumentar a oferta de produtos, seja para melhorar os níveis de produção, produtividade, renda e emprego. Por outro lado, existe a preocupação com a disponibilidade dos recursos hídricos para dar suporte ao crescimento da agricultura irrigada. Esta análise e busca de solução passam inexoravelmente pela disponibilidade de informações técnicas e científicas que possam dar suporte ao processo, informações essas de estudos e caracterizações dos recursos hídricos superficiais e subterrâneos. Integra-se neste tema a questão de produzir sempre com base na sustentabilidade que envolve as áreas de meio ambiente, social e econômica. O tema de recursos hídricos e sustentabilidade é abordado dentro das diferentes abordagens da agricultura irrigada no Brasil, desenvolvido por profissionais de diversos setores dessa área, constituindo uma importante contribuição para o desenvolvimento sustentável da agricultura irrigada brasileira e mundial.
