“…Furthermore, there are also some indications that P interferes with synthesis and deposition of starch in some cultures (Rosen, Kelling, Stark, & Porter, 2014;Zhao et al, 2015;A. P. Oliveira, Silva, Pereira, & Barbosa, 2005); however, this behaviour was not observed in this study.…”

The banana fruits of 'FHIA 18' have sensory properties like the 'Prata' ones. However, there is no information regarding to phosphorus (P) requirement of this hybrid and its effects on postharvest quality. This study aims to evaluate the physicochemical properties of 'FHIA 18' banana fruits submitted to different phosphorus levels under the edaphoclimatic conditions of the municipality of São Manuel, state of São Paulo, during three successive production cycles. Therefore, different levels of Phosphorus (0 [0%], 20 [50%)], 30 [75%], 40 [100%], 50 [125%] and 60 kg ha -1 year -1 P 2 O 5 [150%]) were applied during three production cycles. A completely randomized design and split plot structure was used, the plots consisted of six phosphorus fertilizers doses and three production cycles (2014, 2015 and 2016) in sub plots. For unripe fruits, we evaluated the contents of dry matter, starch, total sugars, reducing sugars and phosphorus. For ripe fruits, we analyzed firmness, peel colour descriptors, total titratable acidity, total soluble solids, maturity index, total sugars and reducing sugars. Results showed that P fertilizer provided an increase in P content in unripe fruits until the application of 100% of the recommended dose; besides an increase in the reducing sugar contents until the application of 61% over the first production cycle. Results also indicated that applying lower phosphorus doses (˂100% of the recommended dose) promoted lower total titratable acidity and higher maturity index (52-53% of recommendation) in ripe fruits. Regardless of P 2 O 5 dose, the contents of dry matter, starch and phosphorus increased in unripe fruits from first to third crop cycle, as well as the firmness, total soluble solids contents, maturity index and sugar content in ripe fruits. ResumoOs frutos da bananeira 'FHIA 18' possuem características sensoriais semelhantes à banana 'Prata', porém, não existem informações sobre as reais necessidades em fósforo (P) deste híbrido e seus efeitos Semina: Ciências Agrárias, Londrina, v. 41, n. 1, p. 33-48, jan./fev. 2020 Bolfarini, A. C. B. et al.na produção e qualidade pós-colheita. O objetivo deste trabalho foi avaliar o perfil físico-químico dos frutos da bananeira 'FHIA 18' submetida à níveis de adubação fosfatada, em São Manuel-SP, durante três ciclos sucessivos. Os níveis de adubação com P 2 O 5 aplicados foram: sem adubação com P (0%); 20 kg ha -1 ano -1 (50%); 30 kg ha -1 ano -1 (75%); 40 kg ha -1 ano -1 (100%); 50 kg ha -1 ano -1 (125%); e 60 kg ha -1 ano -1 (150%). Utilizou-se o delineamento inteiramente casualizado, em arranjo de parcelas subdivididas, sendo as parcelas compostas pelos seis níveis de adubação com fósforo e as subparcelas pelos três ciclos de produção (2014, 2015 e 2016). Foram avaliados nos frutos verdes os teores de matéria seca, amido, açúcares totais, açúcares redutores e de fósforo. Nos frutos maduros avaliou-se a firmeza, os descritores de coloração da casca, acidez titulável total, sólidos solúveis totais, índice de maturação, açúcares totais e açúcare...

“…Essa diferença é explicada pelos 90 dias em que esse cultivar permaneceu no campo, além dos 180 dias do seu ciclo. Esse período a mais ocasionou no consumo do amido pela própria planta, resultando no baixo valor encontrado experimentalmente, pois as condições de umidade, temperatura, precipitação e adubação, além do tempo em que a batata-doce permanece no campo, são fatores que alteram a porcentagem de amido nas mesmas (CEREDA; VILPOUX, 2001;OLIVEIRA et al, 2005).…”

Estudou-se o incremento na produção convencional de etanol de batata-doce [Ipomoea batatas (L.) Lam.] incorporando soro de queijo ao processo e a variação nos teores de proteína bruta dos resíduos sólidos úmidos gerados por esses processos utilizando-se dois cultivares selecionados no estado do Tocantins. O incremento na produção convencional de álcool de batata-doce alcançou um porcentual de 16,6% quando o soro de queijo hidrolisado foi incorporado ao processo, resumidos em até 28,9 litros a mais de etanol por tonelada de raiz. Houve uma variação no teor de proteína bruta nos resíduos sólidos úmidos gerados nos processos substituídos pelo soro de queijo em comparação ao gerado pelo processo testemunha de até 32,1% a mais de proteína. Os resultados obtidos mostram a viabilidade da incorporação do soro de queijo no processo convencional de produção de etanol de batata-doce, possibilitando o reaproveitamento deste coproduto da indústria de laticínio.

“…Positive results from phosphated soil fertilization on sweet potato performance are found in the literature. Oliveira et al (2005b) in studies conducted in Areia-PB evaluating the phosphorus fertilization ranging from 0 to 400 kg ha -1 P 2 O 5 , reported that total (23.5 t ha -1 ) and commercial (18.9 t ha -1 ) production of sweet potato were reached with P 2 O 5 doses 259 and 231kg ha -1 , respectively. Hameda et al (2011) found significant increases in the total sweet potatoe yield from 13.8 t ha -1 , at 15 kg ha -1 of P 2 O 5 to 16.14 t ha -1 when the P 2 O 5 dose was 45 t kg ha -1 , i.e.…”

Mineral nutrition and yield of sweet potato according to phosphorus doses

et al. 2016

The sweet potato is a vegetable with potential for expansion of its production area, due to its versatility of use, as it can be used as food, feed and biofuel. However, there is limited information on the mineral nutrition and performance of this vegetable in response to fertilization, especially phosphorus, which is a nutrient with strong interaction with the soil. Given the above, the aim of the present study was to evaluate phosphorus fertilizer levels on growth, mineral nutrition and sweet potato productivity. An experiment carried out from September 3, 2011 until January 3, 2012, in São Luis-MA, aimed to evaluate phosphorus fertilizer levels on growth, mineral nutrition and productivity of sweet potato plants. The experimental design was a completely randomized blocks with four replications. Harvest took place 123 days after seedling transplantation. Phosphorus doses influenced the P level in the soil, plant aerial and root dry matter, total and commercial productivities, and the accumulation of P in the plant aerial part dry matter, tuberous roots and the total plant. The foliar P content was verified to follow a linear adjustment to the doses of P2O5 whereas total and commercial productivities of roots followed a quadratic adjustment. Maximum productivity (1.68 kg m-2) resulted when the P2O5 dose was 191 kg ha-1. The optimal economical dose was 104 kg P2O5 ha-1, that is, 54% of the dose that resulted in the highest commercial productivity.
