Nutrição mineral e qualidade do fruto de algumas frutíferas tropicais: goiabeira, mangueira,bananeira e mamoeiro

Fruit quality is the result of the action of several factors, in particular the individual and combined effect of mineral nutrients. The proper evaluation of mineral nutritional requirements causes that fruit plants can express all their genetic potential. Thus, a research has been conducted in tropical fruit, for evaluating the influence of mineral nutrients on fruit quality; however, they appear dispersed. The objective of this review was to compile and report the effects of mineral nutrients on fruit quality of guava, mango, banana and papaya. Consequently, information about the influence of the essential elements in color, flavor, shape, size, appearance, penetration resistance, physiological disturbs disease incidence, physicochemical characteristics and lifetime of post - harvest fruit are presented.

Extração e exportação de nutrientes pelo feijoeiro adubado com nitrogênio, em diferentes tempos de implantação do sistema plantio direto

Common bean grown in no-tillage (NT) systems has increased markedly in Brazil. Thus, to optimize the fertilizer recommendations, it is important to know the nutritional requirements of this crop when grown under new and established NT systems, which can change the nutrient availability and crop response to nitrogen (N) fertilization. The objective was to evaluate the extraction and exportation of nutrients by common bean as function of N fertilization on soil under new and established NT systems. The experiment was carried out in two agricultural years, on a Red Nitosol (Alfisol) in Botucatu, São Paulo State, Brazil. A randomized complete block design was used in a split-plot scheme with four replications. The plots consisted of areas under NT systems after different periods of adoption and the subplots of four forms of N application to common bean (T0: control, without nitrogen; T1: 60 kg ha-1 before sowing; T2: 60 kg ha-1 sidedressed at V4 stage; and T3: 60 kg ha-1 before sowing + 60 kg ha-1 sidedressed). The following properties were evaluated: shoot dry matter, nutrient concentration and accumulation in the shoot, grain yield, and nutrient concentration and exportation in the grains. The NT age did not affect common bean yield, nutrition and response to N management. Nitrogen application, especially before sowing, led to higher dry matter and nutrient accumulation by common bean. The nutrient concentration in grains was little influenced by N fertilization. Grain yield and nutrient exportation were highest after double N application (before sowing and sidedressed) or only sidedressed at V4.

Absorção de nutrientes em cultivares de gérbera cultivada em vaso

The analysis of the uptake of nutrients is important for understanding the nutritional requirements of a cultivar during its development and identifies periods of increased demand, which allows scheduling fertigation. Nevertheless, the information is limited for gerbera. Thus, the present study was conducted to determine the uptake of potted gerbera cultivars Cherry and Red conducted in substrate in a crop cycle in the period August-October 2008. The experiment was carried out in a greenhouse in a randomized block split plot with four replications. The plots were composed by cultivars and subplots by dates of collection. During the development of the plants, the content and accumulation of macro and micronutrients was assessed in plant tissue of the shoots. The macronutrients were accumulated in the following order: K>N>Ca>Mg>P>S (524, 334, 119, 47, 42, 21 mg plant-1). The micronutrients were accumulated in the following order: Fe>Mn>B>Zn>Cu (7897, 1505, 801, 384,63 µg plant-1). The reproductive was the period of greatest uptake of nutrients, except for Fe.
