Adubação Foliar Na Qualidade E Produtividade De Abacaxi

Abstract

on 72,000 ha, with a 24.82 t ha -1 yield index (IBGE 2007). São Paulo State has a cultivated area of 3,414 ha and produces 114,000 tons, while Guaraçaí is one of its main producers, with a cropped area of 1,500 ha and 45,000 tons yield (IEA 2008).

Potassium Fertilization on Fruits Orchards: A Study Case from Brazil

“…In this experiment the influence of potassium on the soluble solids content, which values ranged from 13 to 13.50 ºBrix, was not verified. According to observations performed by [78], the soluble solids contents, found in fruits of Smooth Cayenne fruit tree, which varied from 13.74 to 15.50 ºBrix, were also not directly influenced by K 2 O treatments. In a trial performed by [79], the positive effect of potassium fertilization on total soluble solids contents (TSS) was observed, which the application of 490 kg ha -1 K 2 O increased the TSS in about 6%.…”

Leaf fertilization in nutritional supplementation of micropropagated pineapple cultivars

“…A arquitetura, morfologia e anatomia do abacaxizeiro contribuem para a absorção foliar de nutrientes, como por exemplo, a disposição das folhas que surgem em formato de calha. Além disso, a presença de parênquima aquífero nas folhas favorece o armazenamento de líquidos, contribuindo para uma boa retenção dos nutrientes aplicados via foliar (Maeda et al, 2011). Assim, objetivou-se estudar os efeitos de composições de adubo foliar no crescimento e produção de cinco cultivares de abacaxizeiro micropropagadas.…”
