“…In irrigated fruit-growing areas in semiarid regions of Brazil, using water-saving irrigation strategies is critical to an environmentally sustainable production (SANTOS et al, 2019). This is particularly important for bananas, which need a constant, large supply of water throughout the year (TURNER et al, 2007).…”

“…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.…”

“…In semiarid conditions, a higher plant density prevents plants from damages caused by strong winds and excessive radiation, decreases weed population and herbicide use, improves cooling within banana plantations, reduces water evaporation from the soil, and increases WUE (DONATO et al, 2015;SANTOS et al, 2019). Additionally, increasing plant density contributes to the decrease in incidence of Black and Yellow Sigatokas and the fungicide use associated with them because Sigatokas are less severe under decreased sunlight ambient (CAVALCANTE et al, 2014).…”

“…However, plant responses to increased plant density are site-specific and related to interactions between soil, water, genotype and environment. Thus, studies on combining irrigation strategies with high plant population densities are needed for bananas grown in semiarid regions (SANTOS et al, 2019).…”

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.

“…Na maioria das plantações de banana, são as chuvas que fornecem a água requerida à manutenção das plantas, entretanto são cada vez mais frequentes os sistemas de irrigação, objetivando aumentar a produção e potencializar o plantio em áreas até então inadequadas (COLTRO;KARASKI, 2019;MWAURA;MUWANIKA, 2018;SANTOS et al, 2019). Ressalta-se que as mudanças climáticas podem ocasionar variação na qualidade e na quantidade de frutas produzidas, uma vez que alterações de temperatura e de sazonalidade das chuvas e aumento na frequência de intempéries climáticas, como vendavais, furacões e tornados, podem influenciar no cultivo da banana (SABIITI et al, 2017;SALVACION, 2019;SALVACION et al, 2019).…”

A banana é a segunda fruta mais consumida no mundo. Seu cultivoproduz grandes quantidades de resíduos lignocelulósicos, descartadosmajoritariamente de maneira inadequada. Muitas vezes esses resíduos sãopotenciais meios de proliferação de vetores, além de contribuir, mediantedecomposição, para a geração de gases que ocasionam o efeito estufa.Assim, buscou-se identificar, por meio de uma pesquisa sistemática em basesde dados (Periódicos Capes, Science Direct e Springer Link), alternativas paraa reutilização e consequente valorização desses resíduos. Propôs-se realizaruma análise temporal quantitativa e qualitativa dos artigos selecionados,identificando o número de publicações por ano e os periódicos em queforam publicados. Identificou-se crescente número de artigos publicados naúltima década, na maioria em periódicos de alto impacto (índice SCImago).Dessa forma, constatou-se que a produção de compósitos, biocombustíveise compostos adsorventes são as principais alternativas para se atribuirmaior valor agregado aos resíduos da bananicultura e, consequentemente,promover seu reaproveitamento.

The objective of this study was to assess the effect of planting densities, irrigation levels and bunch trimming on yield, fruit grading and water-use efficiency (WUE) of ‘Prata-Anã’ banana plants. The following factors were combined in a randomized block design: three irrigation levels (IL), 50, 75 and 100% crop evapotranspiration (ETc); four planting densities (PD)- 1,666; 2,083; 2,666 and 3,333 plants ha-1; and two bunch trimming treatments (BT), removal of either one or two hands from the bunch. The treatments were arranged in a split-split plot design. Irrigation level was assigned to main plots, PD to subplots and BT to sub-subplots, with four replicates. Measurements were made in the first production cycle. Removing two hands increased number of leaves, leaf area, leaf area index, fruit weight, fruit diameter, total hand weight and mean hand weight of ‘Prata-Anã’ banana plants. A plant density population of 3,333 plants ha-1 combined with an irrigation level at 75% ETc improves plant development and yield while maintaining fruit size and saving water, regardless of removal of one or two hands from the bunch.
