Yield, chemical composition, growth and maturity of ‘Williams’ banana fruit in relation to supply of potassium, magnesium and manganese

Relative importance of location and period of banana bunch growth in carbohydrate content and mineral composition of fruit

“…Climatic conditions, soil composition and cultivation practices are known to influence the chemical composition of fruits [24][25][26][27][28][29]. In our study, we attempted to reduce the impact of certain factors such as water stress [27] and fertilisation [25,26] by irrigating during dry periods and by applying similar types and quantities of fertilisers at all sites.…”

Effects of Black Leaf Streak Disease and Sigatoka Disease on fruit quality and maturation process of bananas produced in the subtropical conditions of southern Brazil

“…The effects of BLSD observed in this study resembled the effects of other cropping stresses on banana fruit growth. Stresses associated with mineral deficiencies, water supply (excess or shortage) and heavy defoliation have a very clear impact on fruit growth rate (Turner and Barkus, 1982;Hegde and Srinivas, 1989;Goenaga and Irizarry, 1998;Chillet et al, 2006). It seems that BLSD causes a greater physiological stress than SD.…”

Estimativa das necessidades nutricionais de bananeiras do subgrupo Cavendish cultivadas no Estado de São Paulo

“…De acordo com Malburg & Lichtemberg (1986), as diferenças devidas às condições de cultivo tendem a diminuir quando a remoção é expressa por tonelada de cachos. Turner & Barkus (1982) observaram em experimento de campo com a bananeira 'Williams' que a concentração de K nos cachos variou pouco em função do teor de K no solo e que a exportação desse elemento seria, portanto, função direta do rendimento.…”

“…Segundo Turner & Barkus (1982), conhecer a composição química dos cachos é importante para estimar a reposição dos nutrientes exportados pela cultura. Para cultivos comerciais, com rendimentos de 50 t ha -1 ano -1 , em solos minerais, e empregandose variedades do subgrupo Cavendish, Lahav (1995) No Brasil, Borges & Oliveira (2000), trabalhando com sete cultivares de bananeira na região Nordeste, estimaram que a exportação foi de 1,9 kg de N por tonelada de cachos; de 0,22 kg t -1 de P e de 5,6 kg t -1 de K. Segundo Malburg & Lichtemberg (1986), a exportação de nutrientes pela cultura, especialmente N, P e K, quando expressa por tonelada de cachos, apresenta pouca variação, ainda que estejam envolvidas diferentes condições ambientais, cultivares ou épocas.…”
