“…Thus, it is assumed that the low level of calcium in the organic solutions did not affect the antioxidant capacity of the organic melons that were produced. There is evidence that the application of different levels of the macronutrient nitrogen via fertigation does not affect the phenolic content of melon fruits obtained under open field conditions (Ferrante et al, 2008). Other researchers have reported that the production of nitrogen-containing compounds, such as amino acids, proteins and alkaloids, increases in crops under production systems with a sufficient nitrogen supply (Hallmann and Rembiałkowska, 2012).…”

“…An alternative that has been used to manipulate the synthesis of antioxidants and phytochemical compounds in vegetable produce is the application of organic fertilizers (Benavides-Mendoza, 2002), including organic nutrient solutions, such as compost and vermicompost teas (PreciadoRangel et al, 2011). Moreover, it is known that the most efficient practice for supplying fertilizer is through the irrigation water (fertigation) as a nutritional solution (Ferrante et al, 2008). However, these nutritive solutions must be diluted to avoid phytotoxicity, thereby reducing the nutrient supply, which may represent an additional stress for growing plants.…”

Consumption of fruits and vegetables provides natural antioxidants in the human diet that are capable of preventing diseases resulting from the action of free radicals. The aim of the current study was to evaluate the effect of organic nutrient solutions on the nutraceutical quality of hydroponic cantaloupe melon (Cucumis melo L.) produced under greenhouse conditions. The applied organic solutions consisted of compost and vermicompost teas and vermicompost leachate, while Steiner nutrient solution was used as a control. Analytical tests were run to determine the antioxidant capacity and total phenolic content of the melon fruits. The nutraceutical quality (antioxidant capacity and phenolic content) of the fruits fertilized with the organic solutions was higher than that of melons fertilized using Steiner solution. Treatment with vermicompost leachate led to the highest antioxidant capacity and phenolic content among all of the treatments, resulting a 46.1% higher in antioxidant capacity (DPPH + method) and a 29.3% higher phenolic content compared with inorganically fertilized fruits. Vermicompost solutions (leachate and tea) are viable alternatives for use as a nutrient source in the production of hydroponic cantaloupe melon with improved nutraceutical quality under greenhouse conditions.

“…The results suggest that the fruit quality was affected adversely by excess N, resulting in fruits with a large seed cavity and therefore with small edible parts and greater skin thickness. The N application and N content in the fruit and whole plant were not correlated with the flesh firmness or TSS, in agreement with Ferrante et al (2008). Rodríguez et al (2005) found no changes in the sugar content of Galia melon when they increased N fertilizer from 80 to 240 mg L -1 and Kirnak et al (2005) stated that N application generally has little or no effect on the TSS.…”

The need to reduce nitrogen (N) fertilizer pollution strengthens the importance of improving the utilization efficiency of applied N to crops. This requires knowledge of crop N uptake characteristics and how fertilization management affects it. A three-year field experiment was conducted from May to September in central Spain to investigate the influence of different N rates, which ranged from 11 to 393 kg ha -1 , applied through drip irrigation, on the dynamics of N uptake, nitrogen use efficiency (NUE), fruit yield and quality of a 'Piel de sapo' melon crop (Cucumis melo L. cv. Sancho). Both N concentration and N content increased in different plant parts with the N rate. Leaves had the highest N concentration, which declined by 40-50% from 34-41 days after transplanting (DAT), while the highest N uptake rate was observed from 30-35 to 70-80 DAT, coinciding with fruit development. In each year, NUE declined with increasing N rate. With N fertilizer applications close to the optimum N rate of 90-100 kg ha -1 , the fruits removed approximately 60 kg N ha -1 , and the amount of N in the crop residue was about 80 kg N ha -1 ; this serves to replenish the organic nutrient pool in the soil and may be used by subsequent crops following mineralization.Additional key words: Cucumis melo; fertilization; N distribution; N use efficiency; N removal; N in crop residues. ResumenInfluencia de la fertilización nitrogenada en la dinámica de absorción de nitrógeno, producción y calidad del melón 'Piel de sapo'La necesidad de reducir la contaminación procedente de la aplicación de fertilizantes nitrogenados refuerza la importancia de mejorar la eficiencia de utilización del nitrógeno aplicado a los cultivos. Durante tres años se realizaron ensayos de campo al aire libre en los meses de mayo a septiembre en la zona centro de España para investigar la influencia de distintas dosis de N, en la dinámica de absorción de N, eficiencia del uso del N (NUE), producción y calidad de un cultivo de melón (Cucumis melo L. cv. Sancho) 'Piel de sapo'. Las dosis de N variaron desde 11 a 393 kg ha -1 y se aplicaron a través del riego por goteo. Tanto la concentración como el contenido de N aumentaron en las distintas partes de la planta a medida que la dosis de N aumentó. La hoja fue el órgano con la mayor concentración de N, decreciendo un 40-50% a partir de los 34-41 días después del transplante (DAT). La tasa de absorción de N más alta se observó desde los 30-35 hasta los 70-80 DAT, coincidiendo con el desarrollo del fruto. En cada año, el NUE descendió con el incremento de la dosis de N. Con aplicaciones de N cercanas a la dosis óptima de 90-100 kg ha -1 , los frutos extrajeron aproximadamente 60 kg N ha -1 , y la cantidad de N en el residuo del cultivo estuvo alrededor de 80 kg N ha -1 . Este residuo sirve para rellenar la reserva de nutrientes orgánicos del suelo y puede ser usado por los cultivos posteriores después de su mineralización.Palabras clave adicionales: Cucumis

“…Other authors have found no significant effect of N in antioxidant activity of other crops, such as melons (FERRANTE et al, 2008) and watercress (KOPSELL et al, 2007). Nevertheless, Ibrahim et al, (2012) have reported the reduction of antioxidant activity of leaves, stems, and roots from a medicinal plant (Labisia pumila Blume) with an increase in N supply.…”

-Tomatoes are an important component of the human diet because they are rich in minerals and antioxidants that sequester free radicals in cells, preventing various disorders that affect human health. Here, we aimed to evaluate the effects of different nitrogen sources and concentrations on antioxidant capacity and physical and chemical quality of tomato fruit. The experiment was conducted in Vitória da Conquista, state of Bahia, Brazil, in the experimental field of Universidade Estadual do Sudoeste da Bahia. The experimental setup included a randomized block design with four replicates in a factorial layout of 3 × 3 + 1 (control), for a total of 40 plots. The three treatments comprised different nitrogen sources (calcium nitrate, urea, and ammonium sulfate), applied in three doses (140, 280, and 420 kg ha -1 ). We evaluated firmness, pH, titratable acidity -TA, soluble solid -SS, SS/TA ratio, ascorbic acid, carotenoids, flavonoids, phenolic compounds and DPPH inhibition, were evaluated after samples were harvested. However, increasing concentrations of N adversely affected the acidity and led to an increase in the SS/TA ratio. Increasing the N concentration also reduced the content of bioactive compounds. excluding carotenoids, which consequently impaired antioxidant activity.Keywords: Solanum lycopersicum L..

QUALIDADE E ATIVIDADE ANTIOXIDANTE DE TOMATE CULTIVADO SOB DIFERENTES FONTES E DOSES DE NITROGÊNIORESUMO -O tomate é um importante componente da dieta humana, pois é rico em sais minerais e compostos antioxidante que sequestram os radicais livres presentes nas células do organismo, evitando vários distúrbios na saúde humana. O presente trabalho teve o objetivo de avaliar os efeitos de fontes e doses de nitrogênio sobre a capacidade antioxidante e a qualidade físico-química dos frutos do tomateiro. O experimento foi realizado na cidade de Vitória da conquista -BA, no campo experimental da Universidade Estadual do Sudoeste da Bahia. O delineamento experimental utilizado foi em blocos casualizados, com quatro repetições em esquema fatorial 3 × 3 + 1 (testemunha), totalizando 40 parcelas. Os tratamentos foram compostos por três fontes de Nitrogênio (nitrato de cálcio, ureia e sulfato de amônio) e três doses (140, 280 e 420 kg ha -1 ). Após a colheita foram avaliados os atributos da qualidade do fruto: firmeza, pH, acidez titulável, sólidos solúveis, ratio, ácido ascórbico, DPPH, compostos fenólicos, carotenoides, flavonóides. Os níveis crescentes de N influenciaram negativamente nos conteúdos de acidez titulável, por outro lado, proporcionou aumento na relação SS/AT. Os incrementos de N também reduziram o conteúdo de compostos bioativos, exceto carotenoide, consequentemente prejudicou a atividade antioxidante.
