Macronutrientes em cultivares de gérbera sob dois níveis de fertirrigação

Abstract: Macronutrients in gerbera cultivars under two fertigation levelsPotted gerbera is known world-wide as an ornamental plant; althought there is a reduced volume of information on its cultivation, specially nutrition and fertilization, essential factors for profits in the productive quality. In the present work the content and accumulation of macronutrients was evaluated in four gerbera cultivars under two levels of fertigation. The experiment was carried out in a greenhouse, from May to July, 2006. The experimen… Show more

“…Para níveis de CE semelhantes ao utilizado na presente pesquisa, Beckmann-Cavalcante et al (2010) obtiveram valores semelhantes de fitomassa seca da parte aérea. As inflorescências são consideradas drenos de assimilados, e assim sua remoção, no início do desenvolvimento, resulta em contínuo acúmulo de fitomassa nos tecidos vegetativos (Woodson e Boodley, 1983), importante para flores envasadas (Ludwig et al, 2010).…”

“…O K foi o nutriente absorvido em maior quantidade pelas plantas de crisântemo, o qual concorda com a alta exigência de K pelas plantas da família Asteraceae, tais como gérbera (Ludwig et al, 2008), áster (Camargo et al, 2005) e crisântemo (González e Bertsch, 1989). …”

“…According to these authors, P leaf contents in gerbera in the experiment ranged from 2.4 to 5.7 g kg -1 . In an experiment with different cultivars of potted gerbera and two nutrient solutions as nutrient sources, Ludwig et al (2008) obtained an average content of 2.6 g kg -1 P in the plant leaf tissue. For the commercialization of potted gerbera, plant height must be from 14 to 30 cm (IBRAFLOR, 2016).…”

“…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).…”

“…After this period, the solution was filtered and only the liquid phase, called liquid organic fertilizers (LOF), was used. The dilution of compounds was based on potassium element, according to the indication Ludwig et al (2008). The LOF's were chemically characterized.…”
