“…Under these conditions, energy is transferred for the purpose of osmotic adjustment, what may compromise certain physiological processes and reduce plant growth (Brady & Weil 2013, Taiz et al 2017). This effect is more evident and worrisome in plants in the early stages of development (Brady & Weil 2013) and in systems where minimum drainage is adopted (Beckmann-Cavalcante et al 2010), as occurred in the present study. Furthermore, it is important to note that, although the pH solution varied as a function of electrical conductivity (Table 1), the values were within the appropriate range for nutrient solutions.…”

“…The benefits of this technique are a better fertilizer distribution in the container and the ability to increase the number of fertilizer applications, improving the nutrient absorption by plants (Duenhas et al 2005). For citrus seedlings, fertilization via fertigation was found to be more efficient than slow-release fertilizers at providing the recommended amount of nutrients (Boaventura 2003). Fertigation is a technical and economically viable process commonly used for coffee crops (Fernandes et al 2007), but it has yet to be studied for the production of coffee seedlings.…”

The use of quality seedlings is important in establishing a productive coffee crop. However, the most widely used method to produce coffee seedlings is time consuming (6-12 months) and lacks new production technologies. This study aimed to assess the use of fertigation and a growth regulator in the production of coffee seedlings, in order to develop a system faster than the conventional method. For that, Topázio coffee cultivar seeds were pre-germinated and planted in tubes filled with substrate (composted pine bark), in a protected nursery. A randomized block design was used, in a 4 x 2 (fertigation levels x the use or not of growth regulator) factorial scheme, with four replications. Daily fertigation positively influenced all the growth variables evaluated. The foliar spraying of the growth regulator had little effect on seedling growth. When compared to the conventional system described in the literature, the coffee seedling production system described here reduced, by around 60 days, the production time and enables a large-scale production.

“…G. L. Souto et al Durante o período da lixiviação do solo, as plantas dos tratamentos com drenagem foram irrigadas diariamente com cada tipo de água e o volume aplicado foi registrado. No dia da lavagem, aplicavase paulatinamente, com auxílio de proveta graduada, o volume de cada tipo de água até o início da drenagem do solo; em seguida adicionava-se mais 10% do total aplicado, referente à fração de lixiviação (AYERS; WESTCOT, 1999) para promover a lixiviação dos sais do solo de cada vaso (CAVALCANTE et al, 2010).…”

“…This is mainly due to the reduced cycle of potted crops and the nutrients provided by readily available mineral fertilization (Castro et al, 2010;Beckmann-Cavalcante et al, 2010). However, there is a growing interest among producers and consumers for the production of alternative forms that are less harmful to the environment, necessitating the development of studies regarding organic nutrition.…”

Growth Analysis of Potted Gerbera Conducted With Mineral Fertilization and Organic Fertigation

et al. 2016

(1):111-120. Potted gerbera is an ornamental plant that is widely commercialized in Brazilian markets. However, information on cultivation techniques is needed to meet growing demand, especially with regard to fertilization. This study was carried out to assess the growth of potted gerbera, Florist Red Black cultivar, with mineral and organic fertilization. The experiment was conducted in a greenhouse located at UNIOESTE -Cascavel Campus -PR. The experimental design was composed of randomized blocks with four replicates and five treatments. Treatments were defined according to the fertilization source, which were mineral (NPK) and organic. Organic fertilizers were obtained by diluting in water four organic composts from agroindustrial-waste composting processes. After obtaining composts, water dilution was performed, adjusting the nutritive solution electrical conductivity values. Gerbera plants were assessed fortnightly (0, 14, 28, 42, and 56 days after acclimatization) for leaf area and shoot dry matter, which were adjusted for time using the ANACRES program to obtain the leaf area ratio (LAR), relative growth rate (RGR), and net assimilation rate (NAR). Fifty-six days after acclimatization, plants were assessed for number of leaves, plant diameter, leaf area, leaves and inflorescences dry phytomass, stem height, head diameter, and stem diameter. The highest relative growth rates were obtained in plants grown with organic compost in treatment 3. However, the net assimilation rate, which indicates dry matter conversion efficiency, was highest in plants with chemical fertilization (treatment 1).
