“…From 180 to 360 day of cultivation in pot there was a four-fold increase in nutrient accumulation. Nutrient uptake increases during the reproductive stage of potted gerbera was also observed by Ludwig et al (2008); Guerrero et al (2012) and Ludwig et al (2013). At 360 day of cultivation, the accumulation followed the decreasing order: K > Ca > N > Mg > P > S (1059; 652; 515; 305; 171; and 148 mg per plant), while for micronutrients Mn > Fe > Zn > B > Cu (20.7; 14.9; 3.7; 1.4; and 0.6 mg per plant).…”

Nutrient uptake study is important to understand the plant nutritional requirements during its growth and to identify periods of increased nutrient demand and, thus to establish fertilization program. The objective was to determine the growth and the nutrient uptake by potted foliage anthurium. The experiment was carried out in a greenhouse and the experimental design was completely randomized with ten times of plant sampling (0; 30; 60; 90; 120; 150; 180; 240; 300; and 360 days after transplanting) and five replicates. Anthurium maricense Nadruz & Mayo seeds were germinated in polyethylene trays filled with commercial substrate and the seedlings were transplanted into plastic pots (1.16 L capacity) when reached four leaves. Plant height, leaf number and foliar area were determined every sampling. Blades with petioles, stem, inflorescence and roots were collected and dry mass and nutrients accumulation were determined. Foliage anthurium plants showed initial development but from the 180 days of planting, which corresponds with the beginning of the inflorescence emission, there was a marked increase in height, leaf area, and dry mass and nutrient accumulation. Nutrient accumulation after 360 DAT followed the decreasing order: K > Ca > N > Mg > P > S > Mn> Fe > Zn > B > Cu.

“…Different nutrient demands by cultivars of the same species were observed by Villas Bôas et al (2008) in rose, by Ludwig et al (2013) in gerbera and by Ferreira et al (2012) in chrysanthemum. According to Horn et al (2006) and Rengel & Damon (2008), this difference is due to genetic characteristics and is caused by the variation in the kinetic parameters of nutrient uptake and morphological differences of the root system.…”

Gladiolus is among the most traditional and important cut flowers in Brazil. Silicon (Si) is an element that has increased the production and quality of some ornamental plants. This study aimed at evaluating the production and nutritional status of gladiolus cultivars under greenhouse conditions, according to the Si doses applied to the substrate. The experimental design was randomized blocks, in a 3 x 4 factorial scheme, being three gladiolus cultivars ('White Friendship', 'Rose Friendship' and 'Red Beauty') and four Si doses (0 mg dm-3, 150 mg dm-3, 300 mg dm-3 and 600 mg dm-3), with five replicates. Morphological traits and leaf Si, macro and micronutrients were evaluated. 'White Friendship' and 'Red Beauty' developed taller plants, with a higher diameter and spikes heavier and longer than 'Rose Friendship'. The order of leaf nutrient concentrations for all the cultivars evaluated was the same (K > N > Ca > Mg > S > P > Fe > Mn > B > Zn > Cu), with all of them being classified as Si non-accumulators. Neither the evaluated morphological variables, nor the uptake of the nutrients N, P, K, Ca, Mg, S, B, Cu, Fe, Mn and Zn, were affected by the Si supplementation, suggesting that the addition of Si to the substrate does not enhance the gladiolus production.

“…Santos et al (2017) observed that organic fertilization with industrial waste did not increase shoot and inflorescence diameters of potted gerbera, in relation to mineral fertilization. Ludwig et al (2013) found that P was the fifth macronutrient most required by the Red potted gerbera, and the accumulated amount of nutrient in the plant shoot was 42 mg plant -1 . According to the authors, this value was 12.5; 8.0; and 2.8 times lower than the accumulated amounts of K, N, and Ca by plants.…”

Gerbera can be grown as a cut flower or in pots. However, there is little information on nutrition and fertilization, especially related to phosphorus and the use of organic matter in pots. This study aimed to evaluate the growth and production of potted gerbera under doses of phosphorus and the use of cattle manure. The experiment was carried out in pots, under greenhouse conditions. A randomized block experimental design was used in a 5 x 2 factorial scheme with 4 replications, totaling 40 experimental units. The treatments consisted of 5 P rates: 0, 20, 40, 60 and 80 mg dm -3 P, as triple superphosphate powder and use, or not, of cattle manure. Phosphate fertilization and cattle manure in soil with low P contents did not influence the growth and production of potted gerbera. Phosphorus rates improve the nutritional status of potted gerbera, but do not contribute to the commercial quality of the plants. The use of cattle manure increases the availability of phosphorus in the soil for potted gerbera cultivation without, however, contributing to commercial quality. Potted gerbera is poorly responsive to phosphorus addition, supplied by both mineral and organic fertilizers. Keywords: Gerbera jamesoni, phosphorus, organic manure, nutrients. RESUMO Doses de fósforo e uso de esterco bovino no cultivo de gérbera de vasoA gérbera pode ser cultivada como flor de corte ou em vasos, porém há poucas informações sobre nutrição e adubação, especialmente relacionadas ao fósforo e uso de resíduos orgânicos em vasos. O objetivo do trabalho foi avaliar o crescimento e a produção de gérbera em vaso sob doses de fósforo e uso de esterco bovino. O experimento foi conduzido em vasos, em casa de vegetação. Foi empregado delineamento experimental em blocos ao acaso, em esquema fatorial 5 x 2 e 4 repetições totalizando 40 unidades experimentais. Os tratamentos foram constituídos por 5 doses de P: 0, 20, 40, 60 e 80 mg dm -3 de P, na forma de superfosfato triplo em pó e uso ou não de esterco bovino. A adubação fosfatada e o esterco bovino, em solo com baixo teor de P, não influencia o crescimento e a produção de gérbera de vaso. As doses de fósforo proporcionam melhorias no estado nutricional da gérbera cultivada em vaso, mas não contribuem para a qualidade comercial das plantas. O uso de esterco bovino aumenta a disponibilidade de fósforo no solo para cultivo de gérbera em vaso, sem, contudo contribuir para a qualidade comercial. A gérbera cultivada em vaso é pouco responsiva às adições de fósforo, fornecido tanto por fertilizante mineral como orgânico. Palavras-chave: Gerbera jamesoni, fósforo, adubação orgânica, nutrientes.
