-Introduction. Fruit green-life is a major postharvest attribute on which conservation on commodity chains depends. For climacteric fruits such as banana, green-life must be optimized to fit the transport and market requirements. Calcium was assumed to strengthen cellular tissue and increase the green-life of fruits. Materials and methods. In our study, we tested the effect of preharvest and postharvest calcium applications on attributes of banana fruit for two cultivars (Musa spp., AAA group, cv. Cavendish Grande Naine and Flhorban920 cultivar, AAA group). Results and discussion. Extra calcium in fertilization of Flhorban920 cv. did not significantly affect the green-life of fruits (36 days) or the hardness and thickness of the Flhorban920 cv. skin (63.7 N and 3.94 mm, respectively). The field calcium applications, by fertilization or spraying, did not alter pulp or peel chemical composition. For postharvest treatments, the green-life of Cavendish and Flhorban920 banana was not significantly altered by the presence or absence of calcium, or by the type of application, 45 and 26 days for the Cavendish and Flhorban920 cultivars, respectively.

“…Por isso, pode ser necessária sua suplementação, que é feita por pulverização dos frutos com sais de cálcio, para garantir melhores características destes, já que o cálcio se associa às substâncias pécticas da lamela média e as membranas celulares, preservando as características de permeabilidade da membrana celular (Poovaiah et al, 1988), o que confere maior rigidez ao tecido e, também, diminui a ocorrência de doenças e distúrbios fisiológicos em pós-colheita, como a lanosidade (Conway et al, 1994;Maganaris et al, 2005;Elmer et al, 2007), pois os novos tecidos são formados com o cálcio recém-absorvido, devido às dificuldades de sua remobilização a partir da folha.…”

RESUMO -Na região Sul do Brasil, as aplicações foliares de cálcio têm sido usadas durante o ciclo produtivo do pessegueiro. Entretanto se carece de conhecimentos sobre o teor de cálcio e de outros nutrientes na folha, usada para estimar o estado nutricional da planta, no fruto, utilizado como referência para definir a ocorrência de distúrbio fisiológico e na produção. O trabalho objetivou avaliar o efeito de pulverizações foliares de diferentes fontes de cálcio no seu teor e de outros nutrientes nas folhas, nos frutos e na produção. O trabalho compreendeu dois experimentos e foi conduzido na safra agrícola de 2003/2004, em um pomar comercial de pessegueiro da cultivar Chimarrita, em Pinto Bandeira-RS, sobre um Cambissolo Húmico. O experimento 1 consistiu de uma, duas e três pulverizações foliares de cloreto de cálcio nas concentrações de 0 (água); 0,5; 1,0 e 2,0%. O experimento 2 compreendeu uma, duas e três pulverizações foliares de nitrato de cálcio nas concentrações de 0 (água); 0,5; 1,0 e 2,0%. O delineamento experimental usado nos dois experimentos foi de blocos ao acaso, com três repetições e três plantas por parcela, que foram distribuídas ao longo da linha de plantio. Nas plantas dos dois experimentos, foram coletadas folhas completas (limbo+pecíolo) do terço médio dos ramos do ano, nos diferentes lados da planta, secas, moídas e preparadas para a análise dos teores de cálcio, nitrogênio, potássio e magnésio. Na maturação completa, os frutos foram colhidos e determinados a massa, a produção e os teores de cálcio, nitrogênio, potássio e magnésio. Os resultados mostraram que as aplicações foliares de cloreto de cálcio e nitrato de cálcio durante o ciclo produtivo do pessegueiro aumentaram o teor de cálcio na folha. Porém, não afetaram o teor de nitrogênio, potássio e magnésio na folha, o teor de cálcio, nitrogênio, potássio e magnésio no fruto e na produção.

FOLIAR APPLICATION OF CALCIUM IN PEACH IN SERRA GAÚCHA: EVALUATION OF CONTENT OF NUTRIENTS IN THE LEAF, FRUIT AND YIELDABSTRACT -Foliar application of calcium in Peach tree in the Southern Brasil is used during productive cycle, without any information about calcium content and other nutrients in the leaves, fruits and yield. Two experiments were carried out in 2003/2004 to evaluate the effect of foliar application of different sources of calcium in its content and other nutrients in the leaf, fruit and yield of peach trees, Chimarrita cultivar, at an Haplumbrept soil in Southern Brazil, Pinto Bandeira city. The treatments in the experiment 1 were three foliar applications of calcium chloride, concentrations 0 (water), 0.5, 1.0 and 2.0%.Experiment 2 were three foliar applications of calcium nitrate, concentrations 0 (water), 0.5, 1.0 and 2.0%. A randomized block experimental design was used with three replications and three plants for treatment. Leaves were collected, oven-dried and analyzed total calcium, nitrogen, potassium and magnesium. In the maturation, fruits were collected...

“…The proper programs of foliar nutrition and/or biostimulation should also have positive effects on yield and its storage. It is noticed that, applications of these biostimulators during the pre-harvest period may naturally protect fruits from skin damages, evaporation, fungal (Elmer et al 2007), bacterial, or physiological diseases as well as delay senescence during storage (Favaro et al 2017). For the improvement of the quality and postharvest stability of citrus fruits, foliar nutrition with K and Ca can be applied.…”

IT is well known that, sustainable agriculture is an important part of sustainable development. This sustainable agriculture should lead to achieve food security and maintain the biodiversity of natural ecosystems. Sustainable agriculture also should have definitely a global perspective. The conservation of both soil and water resources, therefore, is considered an essential prerequisite as well as the efficient use of mineral and organic fertilizers. This could be achieved by improving agro-technology and better understanding of the essential processes in soils. Foliar application of agrochemicals including fertilizers should be improved seeking for the sustainability of agriculture. The present review will focus on the effects of foliar application of nutrients for plant nutrition and its biofortification. Proper timing of foliar application, endo-, exogenous and environmental factors affecting foliar nutrition, influence of mineral fertilizer nutritional quality of staple food crops and finally nano-foliar nutrition as well as postharvest quality of crops will be also highlighted.
