“…In detail, in 2009, control plants yielded 18%, 17% and 26% less than trees supplied with aqueous extract enriched with FeSO 4 , aqueous extract alone and Fe-chelate, respectively; whereas in 2010, the losses were estimated at 8%, 16% and 23%, respectively. The reduction in fruit load in untreated trees may be associated with the decrease of fruit number induced by Fe deficiency during flower development and fruit set, as reported also in other studies (see Tagliavini and Rombolà 2001;Pestana et al 2003;Á lvarez-Ferná ndez et al 2006Á lvarez-Ferná ndez et al , 2011, for reviews). Á lvarez-Ferná ndez et al (2006) reported that Fe-deficiency affects fruit number more than fruit size, while an increase in fruit weight is described in moderate chlorotic peach and pear trees and a decrease is reported only in heavily chlorotic plants (Á lvarez-Ferná ndez et al 2011).…”

“…Fe chlorosis in crops occurs mainly as a consequence of a scarce solubility of mineral Fe sources in the soil and of a reduced Fe uptake by the symplast, induced by the soil active lime fraction (Tagliavini and Rombolà 2001). Fe-deficiency decreases leaf photosynthetic pigment concentrations, especially chlorophyll (Chl) (Abadía and Abadía 1993).…”

“…Furthermore, recent findings pointed out physiological alterations of leaf morphology, stomatal control, xylem vessel morphology, leaf hydraulic conductance and leaf water potentials of chlorotic peach leaves, indicating that Fe deficiency implies pronounced disturbances in leaf water relations (Ferná ndez et al 2008;Eichert et al 2010). Fe chlorosis depresses yield and fruit quality, decreases tree vigor and shortens orchard productive lifetime (see Tagliavini and Rombolà 2001;Á lvarez-Ferná ndez et al 2006 for reviews).…”

“…is adopted as rootstock, pear is one of the species most susceptible to Fe chlorosis (Rombolà and Tagliavini 2006). Although synthetic Fe-containing compounds such as Fe-chelate (e.g., Fe-EDDHA) are usually effective in overcoming Fe-deficiency disorder (Lucena 2003(Lucena , 2006, they induce a short-lasting re-greening effect, are expensive (Tagliavini and Rombolà 2001) and represent a risk of water table contamination. In fact, soil-applied Fe-chelates are scarcely degradable (Nö rtemann 1999), easily leached out of the root zone (Rombolà et al 2002) and may induce toxic effects in soil microorganisms (i.e., mycorrhiza) (Grčman et al 2001).…”

The aim of this study was to evaluate the effectiveness of soil-applied aqueous extract of Amaranthus retroflexus L. in preventing lime-induced iron (Fe) chlorosis of pear trees (Pyrus communis L.). Tree growth, nutritional status, yield and fruit quality were also assessed. The aqueous extract was obtained by soaking dried and ground canopy (epigeal part) of spontaneous A. retroflexus plants in tap water. A. retroflexus extract was chosen because of its ability to solubilize Fe from calcareous soil, which was found to be 100-fold higher than deionized water alone. Two experiments were carried out (controlled environment and commercial field conditions) where soil-applied aqueous extract of A. retroflexus alone or mixed with iron sulfate (FeSO 4 ) was compared with synthetic Fe-chelate and an untreated control. Soil-applied aqueous extract of A. retroflexus increased shoot length, leaf SPAD and total plant biomass in controlled environment. In the commercial orchard control trees showed severe leaf Fe-chlorosis symptoms effectively prevented by Fe-chelate. The supply of A. retroflexus aqueous extract improved Fe nutrition of trees, particularly when enriched with FeSO 4 . Fe-chelate increased tree yield but decreased fruit weight, leaf potassium (K) and manganese (Mn) concentration. At harvest, all strategies raised fruit soluble solid concentration compared to the untreated control. Results showed that soil-applied A. retroflexus aqueous extract improved Fe nutritional status of pear trees, probably because of the natural Fe chelating capacity of the compounds released by its tissues.

RESUMONa região de Janaúba, norte de Minas Gerais, não obstante as altas produtividades alcançadas pela bananicultura da região no contexto de uma agricultura altamente tecnificada, com uso intenso de fertilizantes e controle sistemático de doenças e pragas, são comuns os relatos de produtores expressando preocupação com a queda de produtividade, particularmente quando se irriga com água de poços tubulares. Em razão disso, estudou-se o efeito de águas de irrigação provenientes de poços e do rio Gorutuba sobre propriedades químicas de solos sob bananais, onde foram coletadas amostras até 100 cm de profundidade em áreas adjacentes de sequeiro e irrigadas. Observou-se que o uso de águas de poços, de qualidade marginal, causou elevação do pH e dos teores de Ca 2+ e Na + dos solos, elevando as relações Ca/Mg e Ca/K, que se distanciaram da faixa ideal para a cultura da banana. Nos solos irrigados com água de poços houve aumento dos teores de P extraído com H 2 SO 4 , resultante da precipitação do P com o Ca veiculado com a água. Os valores de pH do extrato de saturação do solo foram mais elevados que aqueles registrados na análise de rotina, e a concentração de sais solúveis na solução do solo ocorreu em camadas intermediárias do perfil devido à lixiviação, com destaque para a camada de 30-40 cm dos solos irrigados com água de poços.Termos de indexação: qualidade da água, salinidade, irrigação da bananeira.
