“…As for the efficiency of P use, some plants have a greater capacity to redistribute and reuse nutrients from an older, senescent organ for biomass production (ROZANE et al, 2007). 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 these authors, very tall and thin stems in potted gerbera may not have suffi cient support and cause tipping. Santos et al (2017) obtained a stem length for potted gerbera ranging from 17.6 to 23.3 cm, in an experiment in which organic fertilization from agribusiness waste and mineral fertilization were used.…”

“…Gerbera (Gerbera jamesoni) is commercially cultivated as a cut flower or in pots, and has high acceptance in the market of flowers and ornamental plants in Brazil, for presenting flowers with great diversity of colors, good durability and resistance to transportation (MOTA et al, 2014;LUDWIG et al, 2015;SANTOS et al, 2017). In the cultivation of potted gerbera, it is important to look for a high number of flower stems; inflorescences with large diameter; small size; and adequate leaf branching, to form a balanced set between the vegetative and reproductive part (LUDWIG et al, 2010).…”

“…An adequate fertilization, both mineral and organic, favors the production and quality of flowers and, with the expansion of the commercial production of flowers and ornamental plants in Brazil, there is a need for more studies on fertilization for this group of plants (LUDWIG et al, 2008;MOTA et al, 2014;SANTOS et al, 2015;SANTOS et al, 2017). In addition, in Brazil, it is common for farmers to manage fertilization empirically, supplying large amounts of nutrients, which are often not required by plants, without following agronomic criteria (LUDWIG et al, 2010;GUERRERO et al, 2013).…”

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.

“…At the end of the composting process, organic composts with high electrical conductivity (EC) of 5.63; 8.29; 3.63; and 5.46 dS m -1 , for treatments 2, 3, 4, and 5, respectively, were generated, limiting their use as substrates for the production of potted gerbera. Thus, the dilution of organic composts in water presents a way of supplying the nutritional needs of gerbera's culture, as well as adjusts the EC (Santos et al, 2017). Then, a dilution of the organic compost in order to use only the liquid fraction of fertigation for culture was performed.…”

The objective of this work was to evaluate the production of gerbera inflorescences under the influence of pH and the electrical conductivity of the solution of the substrates irrigated with liquid organic fertilizers. The experimental design was of randomized blocks, with four replications and five treatments. Treatments were defined according to fertilization source, which were mineral (NPK) and organic. Organic fertilization was obtained by diluting four organic compounds from agroindustry residue (reproductive poultry bedding, hatchery waste, flotation sludge, sausage skins, coal from boilers, truck wash residue solid fraction and sugar cane bagasse) in composting process in water. After compounds obtainment, water dilution was performed, adjusting nutritive solution electrical conductivity values. Substrate solution electrical conductivity (EC) and pH determination was held at 1, 14, 28, 42, and 56 days after acclimatization in a 1:5 dilution (m/v). Potted gerberas inflorescences were evaluated at 56 days after acclimatization. Number of inflorescences (NI), inflorescence dry matter (IDM), stem height (SH), head diameter (HD), and stem diameter (SD) were determined. The electrical conductivity of the solution of the substrate in the mineral fertilizer is above indicated for gerbera culture, reflecting the lower inflorescence stem height. The pH values obtained from the solution of the substrates are within the range for the development of potted gerberas.Additional keywords: Gerbera jamesonii; liquid organic fertilizers; salinity. ResumoO objetivo do trabalho foi avaliar a produção de inflorescências de gérbera sob a influência do pH e da condutividade elétrica da solução dos substratos irrigados com fertilizantes orgânicos líquidos. O delineamento experimental foi o de blocos casualizados, com quatro repetições e cinco tratamentos. Os tratamentos foram definidos de acordo com a fonte de fertilização, mineral (NPK) e orgânico. Adubação orgânica foi obtida por meio da diluição de quatro compostos orgânicos diluídos em água, obtidos de resíduos agroindustriais (cama de frango, resí-duos de incubadora, lodo de flotador, tripa celulósica de salsichas, carvão de caldeiras, fração sólida do dejeto suíno e bagaço de cana), no processo de compostagem. Após a obtenção dos compostos orgânicos, realizou-se a diluição com água, ajustando os valores de condutividade elétrica na solução nutritiva. A determinação na solução do substrato da condutividade elétrica (CE) e de pH foi realizada em 1; 14; 28; 42 e 56 dias após a aclimatização em 1:5 (m/v). As inflorescências das gérberas envasadas foram avaliadas aos 56 dias após a aclimatação. Foram determinados número de inflorescências, matéria seca de inflorescências, altura da haste, diâmetro do coleto e diâmetro da haste. A condutividade elétrica na solução do substrato no adubo mineral apresenta-se acima do indicado para a cultura de gérberas, refletindo na menor altura de haste das inflorescências. Os valores de pH medidos na solução dos substratos estão dentro d...

Vegetative tissue analyses might help to diagnose nutritional status of a crop. Foliage diagnosis is an effective method to set up balanced fertilization procedures. The current work aims to evaluate nutrient contents of two gerbera leaf sampling periods as a cut flower cultivated in pots with different doses of nitrogen (N) and calcium (Ca) under greenhouse conditions. The experiment was carried out in a protected environment, shelter type, in a container containing substrate in a 3x3+1 factorial scheme. Three doses of N (0.07, 0.15 or 0.2 g L-1) or three doses of Ca (0.02, 0.03 or 0.04 g L-1) were applied every 15 days. Control plants did receive neither N nor Ca. The substrate was analyzed before and after cultivation, and at the end of production years, as well as completely expanded leaves were collected for nutrient analyses. There was not significant interaction between N and Ca doses. Regarding the sampling period or doses of N and Ca, the determined macronutrient concentrations were in the following order of N>K>Ca>P>S>Mg. The micronutrient concentrations were in the following order of Fe>Mn>B>Zn>Cu. Except for K, all the other nutrient concentrations were in the recommended range for gerberas production.
