Post-harvest characterization of ‘Prata’ banana cultivar grown under different nitrogen and potassium fertilization

Abstract

There are several banana cultivars resistant to Black Sigatoka disease and to Panama disease, but due to the lack of information regarding post-harvest characteristics, many are rejected in the market. Nitrogen and potassium fertilization may help to improve the sensory characteristics of ripe banana, but there is lack of studies on its effects on banana cultivation, especially those resistant to diseases. The aim of this study was to evaluate the post-harvest characteristics of ‘Prata-Anã’, ‘BRS Platina’ and ‘PA94-01’ banana cultivars at four N and K2O fertilization levels (NK0: no fertilization, NK1: 175 and 285 kg ha-1 year-1, NK2: 350 and 570 kg ha-1 year-1, NK3: 525 and 855 kg ha-1 year-1, respectively) in three production cycles. It could be concluded that N and K doses adopted in this work did not influence the post-harvest physicochemical characteristics of ‘Prata-Anã’, ‘BRS Platina’ and ‘PA94-01’ banana cultivars. Regardless of N and K doses, ‘Prata-Anã’, ‘BRS Platina’ and PA94-01’ banana cultivars presented differences regarding post-harvest physicochemical characteristics. Production cycles did not influence the physical characteristics but differed in post-harvest chemical characteristics in ‘Prata-Anã’, ‘BRS Platina’ and ‘PA94-01’ banana cultivars.

Extraction of aromatic compounds from silver banana peel (Musa sapientum): qualitative and sensory approach

“…Brazilians consume, on average, 25.0 kg of bananas per year, and Brazil is the fourth largest banana producer in the world. About 70.0 % of this production corresponds to the silver banana (NOMURA et al, 2019). The silver banana (Musa sapientum) is originally from Southeast Asia, a product of the cross between Musa acuminata and Musa balbasiana, and belongs to the Musaceae family.…”

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

“…According to Salomão et al (2016), due to the importance of this agricultural activity for the Brazilian trade balance, with generation of jobs and source of income for small and large producers, fertilization studies with the objective of productivity gains have been carried out with banana trees of the 'Prata' subgroup (AAB), the most accepted by consumers in the national market (NOBRE et al, 2018;NOMURA et al, 2019;SANTANA JÚNIOR et al, 2020;SANTOS et al, 2017).…”

“…The profitability of an agricultural enterprise is related to the market, product sales price, total production costs and productivity. Proper fertilization management can provide improvements in the vegetative and reproductive development of plants, increasing production per area and, consequently, the business profitability, provided that this increase in productivity exceeds the costs of inputs (NOMURA et al, 2019;RODRIGUES et al, 2018).…”

“…One of the most important Brazilian banana production regions is located in the state of Minas Gerais, especially in the northern region, covering bananagrowing municipalities located 100 km from the capital to neighboring regions such as the banana production region of Bahia in the southwestern state and in the São Francisco River Valley (SALOMÃO et al, 2016). The northern region of the state of Minas Gerais stands out for producing basically the 'Prata-Anã' cultivar (QUEIROZ et al, 2019), especially its clone, known as 'Prata Anã' Gorutuba (FERNANDES et al, 2019;NOMURA et al, 2019).…”
