“…Studies have been carried out investigating irrigation strategies and deficit irrigation techniques (COELHO et al, 2019;SANTOS et al, 2019) in bananas. Increased water-use efficiency (WUE) may be achieved by associating yield-improving practices with water-saving irrigation strategies.…”

Yield-improving and water-saving techniques assume great importance in the cultivation of banana plants under semiarid regions, prone to greater climate variability. The objective of this study was to evaluate yield and water-use efficiency (WUE) response of ‘Prata-Anã’ banana plants to combinations of plant densities and irrigation levels: three irrigation levels, 50, 75 and 100% crop evapotranspiration (ETc), and four plant densities, 1,666 (3.0 x 2.0 m), 2,083 (3.0 x 1.6 m), 2,666 (3.0 x 1.25 m) and 3,333 (3.0 x 1.0) plants ha-1, evaluated in two production cycles. The treatments were laid out in a randomized block design with four replicates. Increasing plant density up to 3,333 plants ha-1 induced reductions in number of leaves at harvest and some yield components; also, longer cycles, and increased yields were observed while maintaining fruit marketable size, regardless of the irrigation level used. Using an irrigation level at 50%ETc and a plant density of 3,333 plants ha-1 led to an increase in WUE of 313.92% in the first cycle and 295.27% in the second cycle compared with 1,666 plants ha-1 irrigated at 100% ETc. Higher yields and WUE can be achieved by using a plant population density of 3,333 plants ha-1 and irrigation levels below 100%ETc.

“…From 1960 to 2015, irrigated areas in Brazil increased substantially, from 462 thousand hectares to 6.95 million hectares (Mha), and can expand more than 45% until 2030, reaching 10 Mha 3 . However, in both public and private irrigation projects, the consumption of water without technical criteria by farmers has negatively contributed to water resources sustainability 5 , 6 . Thus, these scenarios point to the urgent search for strategies of rational use of water in irrigated agriculture, especially considering that irrigation uses about 70% of all the freshwater consumed in the world 7 .…”

“…Thus, these scenarios point to the urgent search for strategies of rational use of water in irrigated agriculture, especially considering that irrigation uses about 70% of all the freshwater consumed in the world 7 . The partial root-zone drying (PRD) technique has been showing as an alternative to increase crop water productivity (crop yields divided by the amounts of water supplied 8 ) when compared to the conventional methods of irrigation management 6 , 9 – 13 . PRD consists of alternating the root system's irrigated side, i.e., while one part of the roots is irrigated, another part is exposed to soil drying 9 .…”

“…Additionally, orange orchard subjected to irrigation depths of 50% and 100% of crop evapotranspiration (ETc), with the lowest irrigation depth applied in the PRD regime, increased fruit yield by 20% and 10% in 2013 and 2014, respectively 16 . Moreover, research carried out with banana cultivation, regardless of the soil type, showed that the interval of alternation of the irrigated side was decisive in reducing the volume of water applied, so that frequencies of 14 and 21 days caused substantial reductions in banana yield compared to 7 days 6 .…”

This study aimed to evaluate in the papaya Tainung genotype, the effects of partial root-zone drying (PRD) technique on soil water regimes by using different frequencies of shifting irrigation-side of plant row and the effects of PRD technique on (1) crop agronomic performance, (2) titratable fruit acidity (TA), (3) total soluble solids (TSS), and TSS/TA ratio. Also, we analyze the spatial dynamic of papaya condition using normalized difference vegetation index (NDVI) from different satellite images. The study was conducted in the semi-arid region of Bahia (BA) and Minas Gerais (MG), Brazil. The combination of 100% (Full irrigation—FU), 50%, and 35% in the irrigation depth (WID) and frequencies of shifting plant-row side irrigation of 0 (Fixed Irrigation—FX), 7, 14, and 21 days were applied. Nine treatments were studied in BA and five in MG. The water available in the soil was reduced to 44% for frequencies of shifting plant-row side irrigation of 7 days, 50% for 14 days, and 85% for 21 days, compared to the soil water availability at field capacity. Partial water deficit in the soil through the PRD technique did not significantly reduce the total root length, effective root depth, and root effective horizontal distance of the papaya Tainung genotype. However, PRD treatments showed leaf abscission, which resulted in reduced leaf area and NDVI values, especially in the MG experiment. Papaya yield and fruit quality were not affected. However, except for PRD 21 35%, irrigation water depth reduced to 50 and 35% under PRD increased crop water productivity (CWP) in papaya plants. Thus, the PRD technique may save 35% of WID using the alternation of lateral shift irrigation of crop row every 7 days under water scarcity in semi-arid regions. The NDVI index was important to compare the papaya canopy vigor between the experimental areas studied. We also confirmed the potential of NDVI to monitor the vigor of papaya canopy, since we could notice the sensibility of NDVI to identify water stress in papaya in higher vapor pressure deficit (VPD) conditions occurred in October 2016 and January 2017 in Bom Jesus da Lapa-BA. Therefore, the PRD strategy can be a useful tool to save water in papaya cultivation under semi-arid conditions.

“…Na cultura da bananeira, estudos com uso da RDI ainda são escassos. Por outro lado, com PRD, Coelho et al (2019) verificaram que as produtividades sob irrigação lateralmente alternada com frequência de 7, 14 e 21 dias, com 50% da evapotranspiração da cultura, promove uma redução na produtividade no segundo ciclo, comparada à produtividade da bananeira sob irrigação plena, no entanto, no primeiro e segundo ciclo, a eficiência de uso da água é maior sob condição de déficit hídrico.…”

A bananeira, cultivar BRS Princesa tem apresentado tolerância a déficit hídrico, sendo de boa aceitação no mercado. A constante instabilidade do regime pluviométrico em todas as regiões do Brasil indica a necessidade de uso mais eficiente de água na agricultura. Objetivou-se com este trabalho, avaliar características de crescimento e de produção da bananeira 'BRS Princesa' sob irrigação com déficit controlado. O delineamento experimental foi o inteiramente casualizado com sete tratamentos e três repetições. O ciclo da cultura foi dividido nas seguintes fases: fase I, do primeiro ao quinto mês; fase II do quinto ao sétimo mês e a fase III, do sétimo ao décimo segundo mês. Os tratamentos consistiram nas aplicações de 60% e 30% da evapotranspiração da cultura em cada fase do primeiro ciclo. A irrigação com déficit hídrico controlado não ocasionou alterações na altura de plantas, diâmetro do pseudocaule, número de folhas e área foliar da bananeira. Os valores médios de redução da produtividade foram maiores para aplicação do déficit hídrico na fase de floração, seguido da fase de crescimento de frutos e pela fase de crescimento vegetativo. Na fase vegetativa, a aplicação de 60% da lâmina total aplicada no ciclo não influenciou a produtividade.
