“…is notable for its social and economic importance and it is a strategic crop for global food security. It is cultivated in tropical and subtropical regions, in an area of 4.8 million ha, with an average fruit yield of 19 t ha -1. , and world production reaches 91.2 million metric ton (Furlaneto et al, 2011). Banana cultivation has a strategic role in the world food production, which is justified by its peculiar nutritional characteristics and yield potential, which can reach 100 t ha -1 .…”

The banana (Musa sp.) crop is notable for its social and economic importance in tropical and subtropical regions of world. In Brazil, despite being a main banana producer, its production is considered low, mainly due to water and nutrient shortages in soils. This fact motivated this study; so, it aimed to evaluate chlorophyll and macronutrients content in leaf tissue of banana 'Prata-Anã' (AAB) under fertigation with doses of nitrogen and potassium. It were evaluated chlorophyll a, b and total and leaf contents of nitrogen (N), phosphorus (P), potassium (K), magnesium (Mg) and calcium (Ca) in banana trees grown in an Ultisol on the coastal tablelands of Sergipe State, Brazil. The experiment was conducted in the field, in a 4 2 factorial with four randomized blocks. Two factors with four levels were tested: nitrogen (0; 350; 700 and 1050, in kg ha-1 of N, as urea) and potassium (0; 400; 800 and 1200, in kg ha-1 of K 2 O, as potassium chloride). Increasing N applied through irrigation enhances leaf nitrogen until approximately 631.08 kg ha-1 of N, while chlorophyll total remains constant after 250 kg ha-1. Phosphorus and calcium are increased due to high doses of N, however, magnesium and potassium in the leaves are reduced. High doses of K increase leaf content of K until estimated dose of 698.07 kg ha-1 and reduce calcium and magnesium of banana 'Prata-Anã'.

“…The high participation of manual operations in the TOC from the production phase (second year) is due to the crop needs in its production process, having high demand for labor, mainly for the harvest of fruits and culture treatments. According to Furlaneto et al (2011), manual operations accounted for about 20% of the TOC after the formation of the banana plantation in the region of Paranapanema, São Paulo.…”

Economic analysis of fertilization management in ‘Prata-Anã’ Gorutuba banana plants

et al. 2022

Brazilian banana farming is one of the most important agricultural activities in the national scenario and can be highly productive and economically profitable for producers who invest in technology. The objective of this work was to compare the economic viability of two different fertilization managements in the cultivation system of 1st -cycle ‘Prata Anã’ Gorutuba bananas. The conventional fertilization treatment (CM), adopted by the producer (control), was compared with the alternative treatment: conventional management + 3 soil conditioners + 1 biostimulant (CM + 3SC + 1B). The four products selected for the alternative treatment were oyster shell limestone, Celtonite, Lithothamnium calcareum and Acadian. The application of the four products in the CM + 3SC + 1B treatment provided satisfactory results on crop performance, mainly due to the increase of 4.032 tons ha-1. The CM+3CS+1B alternative management was more economically viable than CM, as the total operational cost (1st + 2nd year) of the alternative management was 6.71% higher compared to the conventional management; however, the alternative treatment productivity was 28.08% higher. The cost to produce one ton of bananas was R$ 2.456,91 in the conventional treatment and R$ 2.047,07 in the alternative treatment, which represents a 16.68% reduction in the average cost, indicating the economic feasibility of this treatment.

“…Desse modo, o aumento da área produtiva e a identificação de sistemas de produção mais eficientes sob o ponto de vista econômico são primordiais para o aumento da lucratividade do produtor (FURLANETO;MARTINS;ESPERANCINI, 2011). No entanto, a expansão da área produtiva como uma estratégia financeira, se contrapõe ao fato da região do Vale do Ribeira ser considerada uma das prioridades no contexto da conservação da fauna e da flora mundial.…”

Autorizo a reprodução e divulgação total ou parcial deste trabalho, por qualquer meio convencional ou eletrônico, para fins de estudo e pesquisa, desde que citada a fonte. Considerando (1) a importância da bananicultura no Vale do Ribeira, (2) o destaque da Mata Atlântica no contexto da conservação da fauna e flora mundial, (3) a necessidade da adoção de práticas agrícolas alternativas mais eficientes do ponto de vista ambiental e econômico, (4) o papel dos hormônios etileno, acido indol-3-acético (AIA) e ácido abscísico (ABA) no contexto das respostas dos vegetais a diferentes condições ambientais e nos atributos de qualidade da banana, (5) a falta de metodologias otimizadas para a extração de compostos fenólicos solúveis totais (CFST) em bananeiras e (6) a importância do estudo da relação entre os CFST e fatores de estresse, o presente trabalho teve como objetivo avaliar a influência da proximidade do fragmento florestal de Mata Atlântica com a área de cultivo da banana (Musa acuminata AAA cv. Nanicão) sobre o amadurecimento da fruta e os CFST em folhas de bananeiras, além de otimizar uma técnica para a extração destes últimos. Foi observado que bananas colhidas próxima ao fragmento florestal apresentam vidaverde (período compreendido entre a colheita do fruto e o início do seu amadurecimento) maior quando comparados a frutos com a mesma idade fisiológica, porém colhidos em áreas sem a influência da floresta nativa. Este fato pode ser explicado, pelo menos em parte, pela diferença nos perfis de etileno, ABA e AIA ao longo do amadurecimento das bananas provenientes das diferentes áreas, que também influenciam no metabolismo amido-sacarose. Quanto aos CFST nas folhas, foi observado que a utilização de acetona 80% em água (v/v) e posterior emprego de hexano para a remoção do excesso de clorofilas é capaz de obter um bom rendimento de extração de CFST, sem extrair compostos que interferem significativamente no método de Folin-Ciocalteu. Além disso, a utilização da metodologia otimizada mostrou que bananeiras podem apresentar diferenças na sua composição de fenólicos quando influenciadas ou não pela presença de biodiversidade. Assim, a avaliação dos CFST em folhas pode fornecer informações importantes sobre as condições ambientais da planta. Considering (1) the importance of banana production in Ribeira Valley, (2) the Atlantic Rainforest in the context of fauna and flora conservation, (3) the need for the adoption of more sustainable agricultural practices, (4) the ethylene, indole 3-acetic acid and abscisic acid responses in acclimation mechanisms of plants and in the quality attributes of the banana, (5) the lack of methodologies optimized for the extraction of total soluble phenolics compounds (TSPC) in banana leaves and (6) the importance of the relationship between the TSPC content and stress factors, the present work aimed to evaluate the influence of the Atlantic Forest fragments proximity in the banana (Musa acuminata AAA cv. Nanicão) crop area on fruit ripening and leaves TSPC levels, using a optimized me...
