“…The deficiency or excess of some nutrients can directly affect the fruit yield and quality. Nitrogen and potassium, for example, are nutrients that significantly affect the quality of fruit; they are applied in optimal ratios and amounts to the culture and may enhance the physical and chemical characteristics of fruit [19].…”

The use of organic fertilisers in vegetable cultivation is important in the pursuit of increased production to improve the physical, chemical and biological characteristics of the soil, to promote plant growth, and to achieve economically viable productivity for farmers of small-and mediumsized farms. This study aimed to evaluate the development and productivity of eggplant after its fertilisation with a biofertiliser that was composed of sugar and alcohol waste and a bacteria growth promoter for plants. The Ciça genotype of eggplant plants werewas distributed in 20 pots with a Original Research Article capacity of 10 L for each pot. The experiment was conducted using a completely randomised design with four treatments and five repetitions. The following treatments were analysed: control (without any fertiliser), chemical fertiliser (NPK), manure and biofertiliser. The analysed parameters included height, stem diameter, weight and number of fruit. The treatments that received some type of fertiliser (chemical or organic) showed higher plant height, and the 'bio-fertiliser' treatment showed better results than the remaining treatments for all parameters. The results for growth in height, stem diameter and number of fruit demonstrated that eggplant adequately responded to fertilisation with biofertiliser in the experimental conditions and about the assessed conventional fertilisers.

“…A firmeza é uma das características de qualidade que condiciona o grau de resistência a danos mecânicos e determina o tempo de conservação e vida útil de prateleira dos vegetais (REIS et al, 2017). Estudando esta variável, Chaves et al (2014), observaram que a qualidade pós-colheita de melões cantaloupe 'Caribbean Gold' cultivados em diferentes doses de nitrogênio e potássio, ocorreu um decréscimo significativo nos valores de firmeza de polpa durante armazenamento à 5 ºC aos 21, 25 e 29 dias seguido de exposição à temperatura de 20 ºC.…”

Assim como a maioria das frutas, o melão (Cucumis melo L.) enfrenta diversos problemas de conservação pós-colheita, por se tratar de um alimento perecível e possuir alta atividade de água, além das perdas nas etapas de transporte, distribuição, armazenamento e comercialização. O objetivo do estudo foi avaliar a interferência de indutores de resistência na conservação e qualidade pós-colheita de Cucumis melo var. Cantalupensis. Os frutos foram submetidos aos tratamentos com Bion®, Ecolife®, AgroSilício® e como testemunha apenas água destilada. As análises foram realizadas aos 0, 3, 6, 9 e 12 dias de armazenamento, sob temperatura de 25 ±2ºC. Ao final de cada período de armazenamento foram realizadas as seguintes análises: perda de massa fresca, firmeza e cor da casca e da polpa, pH, sólidos solúveis (SS), acidez titulável (AT), relação SS/AT e ácido ascórbico. Os tratamentos não interferiram significativamente sobre as variáveis de pH, parâmetros (a* e b*) da casca, luminosidade (L*) da polpa e sólidos solúveis totais nos frutos de melão (Cucumis melo var. Cantaloupensis), no período de 0 a 12 dias de armazenamento. O AgroSilício proporcionou uma menor perda de massa fresca, acidez e da razão entre sólidos solúveis e acidez titulável (SS/AT). Os maiores teores de vitamina C foram obtidos de frutos de melão tratados com Ecolife, ao final do período de armazenamento.

Conservation and postharvest quality of 'cantaloupe' melon treated with resistance inducer ABSTRACT: Like most fruits, melon (Cucumis melo L.) faces several post-harvest conservation problems, because it is a perishable food and has a high water activity, in addition to losses in the stages of transport, distribution, storage and commercialization. The objective of the study was to evaluate the interference of resistance inducers on the conservation and postharvest quality of Cucumis melo var. Cantalupensis. Cantalupensis. The fruits were submitted to treatments with Bion®, Ecolife®, AgroSilício® and as a control only distilled water. Analyzes were performed at 0, 3, 6, 9 and 12 days of storage, at a temperature of 25 ±2ºC. At the end of each storage period, the following analyzes were performed: loss of fresh mass, skin and pulp firmness and color, pH, soluble solids (SS), titratable acidity (AT), SS/AT ratio and ascorbic acid. The treatments did not significantly affect the variables of pH, parameters (a* and b*) of the skin, luminosity (L*) of the pulp and total soluble solids in the fruits of melon (Cucumis melo var. Cantaloupensis), in the period from 0 to 12 storage days. AgroSilicon provided a lower loss of fresh mass, acidity and the ratio between soluble solids and titratable acidity (SS/AT). The highest levels of vitamin C were obtained from melon fruits treated with Ecolife, at the end of the storage period. Keywords: Acibenzolar-S-methyl; storage; citrus extract; physicochemical; silicon.

“…Experiments carried in Brazil with different doses of N and K allowed determining that the increase of N decreased the pulp firmness even though it favoured the increase in the number and total mass of fruits, being this effect independent of the doses of K (Silva, Rodrigues, Medeiros, Aquino and Silva, 2007) However, different results were found by Chaves et al, (2014). In this work, the fruits submitted to treatment with doses of 666 kg ha -1 of N and 0 kg ha -1 of K 2 O showed higher firmness than fruits treated with doses of 38 kg ha -1 of N and 83 kg ha -1 of K 2 O.…”

summaryThe aim of this work was to study the effect of potassium and calcium in combination with nitrogen upon the yield and fruit quality of outdoor-grown melon (Cucumis melo L.). Two experiments were simultaneously performed through the use of two cultivars: 'Honey Dew Green Flesh' (Inodorus group) and 'Sivan' (Charentais group). A completely randomized experimental design was used with nine treatments resulting in a factorial arrangement of 3 x 3 due to the use of three doses of K and three doses of Ca. Doses were administered through fertigation with the injection of the fertilizers into a drip irrigation system, ) was measured as well as fruit quality attributes: firmness (kg); pulp or mesocarp thickness (mm) and rind thickness (mm); and total soluble solids (%). Differences were observed between the two varieties. The application of K showed the greatest effect on the quality and yield of the harvested fruit. However, this effect was not observed with Ca.
