“…In the seedling stage the plants require adequate agricultural substrates and protection against the climate, as well as appropriate management of irrigation, nutrition and pest control. Studies of substrates for the formation of coffee seedlings have been performed by ANDRADE NETO et al (1999), CUNHA et al (2002); FAVARIN et al (2008), MARANA et al (2008), , while studies with protected environments were conducted by CARELLI et al (1999), BRAUN et al (2007) and TATAGIBA et al (2010).…”

ABSTRACT:The production of high-quality seedlings is a critical factor for successful implementation of a determined crop in the field. In order to evaluate the production of coffee seedlings, experiments were conducted with different substrates and in different protected environments. Treatments consisted of evaluation of the following substrates: 50% cattle manure + 50% commercial substrate, 50% cattle manure + 50% vermiculite, 50% commercial substrate + 50% vermiculite, 1/3 cattle manure + 1/3 commercial substrate + 1/3 vermiculite, 50% cattle manure + 50% sand, 1/3 sand + 1/3 cattle manure + 1/3 commercial substrate and 50% commercial substrate + 50% sand. These substrates were tested in different protected environments: agricultural greenhouse, mesh screen with 50% shading, aluminized screen with 50% shading, black screen with 30% shading, black screen with 70% shading, nursery with a buriti straw roof and full sunlight. In each environment, the experiments were conducted in a completely randomized design with five replicates of four plants each followed by joint analysis. The substrates containing 50% cattle manure associated with vermiculite or the commercial substrate may be indicated for production of coffee seedlings. Screened environments with 30, 50 and 70% shading resulted in the highest quality seedlings.

“…Thus, the knowledge of the best nutritional management strategy will ensure economic gains and quality seedlings. Another advantage of growing coffee seedlings in smaller containers (50 cm 3 or 120 cm 3 ) is a greater plant adherence to the substrate, which does not break up during planting (Favarin et al 2008). However, when comparing the root data obtained here in 50 cm 3 tubes (root length = 12.7 cm; root dry mass = 0.23 g) with those reported by Marana et al (2008) in 120 cm 3 tubes (root dry mass = 0.24 g) and data from studies that used larger containers, such as 180 mL tubes (Der Vliet et al 2009; root dry mass = 0.72 g) and 18 cm x 4 cm bags (Melo & Maciel 2014; root length = 18.9 cm; root dry mass = 0.74 g), it can be inferred that smaller containers may restrict root growth.…”

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.

“…A maioria dos trabalhos realizados com substratos comerciais na formação de mudas de cafeeiro enfoca, predominantemente, aspectos químicos do material, como a dose a ser aplicada, sua composição em nutrientes, a solubilidade da fonte e o tempo de liberação dos nutrientes (Favarin et al, 2008). Entretanto, são escassos trabalhos referente ao uso do gesso agrícola na produção de mudas cafeeiras.…”
