“…After 150 days in the nursery, only plants produced with 7.5, 10.0 and 12.5 kg m -3 of CRF would be suitable for field planting considering parameters established for other species (Binotto et al 2010, Silva et al 2014, Brito et al 2018, Cabreira et al 2019. CRFs provide nutrients to plants slowly, enabling the reduction of losses and ensuring essential elements according to the need in each phase of seedlings production in the nursery (Santos et al 2020). However, results obtained up to 30 days after the CRF application indicate that there is time until plants adapt after the picking and nutrients release is established so that seedlings start to grow properly.…”

In this study, we aimed to evaluate growth and quality of Berberis laurina seedlings submitted to increasing doses of controlled-release fertilizer (CRF). Each treatment was elaborated with different doses of CRF Basacote ® Plus 9M: 0.0, 2.5, 5.0, 7.5, 10.0, and 12.5 kg m -3 . Seedlings were measured at 15, 30, 60, 90, and 150 days in height and stem diameter. At 150 days, we evaluated aerial dry biomass, root dry biomass, height/ diameter ratio, and Dickson quality index. Plants without CRF did not show significant growth in height even after 150 days and treatments with 7.5, 10.0, and 12.5 kg m -3 CRF provided the best results. At dose 12.5 kg m -3 , there was a tendency to decrease height and diameter curves, indicating toxic amounts of FLC to plants growth in nursery. Considering better use of resources, we recommend 7.5 kg m -3 of CRF for the production of B. laurina seedlings.

“…Biomass accumulation in seedlings is an important indicator of seedling growth as it directly reflects the positive result of photosynthesis energy balance (Santos et al 2020). Biomass distribution, in turn, is closely related to the seedling establishment and initial growth in the field (Binotto et al 2010).…”

“…According to the remineralizer producer, the batch of remineralizer used in our experiment had the following nutritional contents: 1.54% Al; B < 10 ppm; 1.22% Ca; 4.32% Fe; 0.11% 66 studies indicate that the use of controlledrelease fertilizers (CRF) ensures efficiency in nutrients availability throughout seedling production process, reducing losses due to leaching or damage due to excess of nutrients in substrates (Stüpp et al, 2015;Van Eerd et al, 2018;Cabreira et al, 2019). In addition, the use of CRF in seedlings production demonstrates a balance between plant physiological demands, according to the availability of nutrients (Santos et al, 2020;Cabreira et al, 2019;Brito et al, 2018). Regarding M. scabrella, studies indicate high salinity resistance (Avrella et al, 2019a) and a positive response to fertilization with CRF (Stüpp et al, 2015).…”

Contextualization: M. scabrella is a native tree species of the Brazilian Mixed Ombrophilous Forest, with a high ecological importance and economic potential. Knowledge gap: There is a lack of information about the use of resources that favour the seedlings production of this species. Purpose: This study aimed to determine the most appropriate doses of controlled-release fertilizer (CRF) combined with the addition of remineralizer for production of M. scabrella seedlings. Methodology: Seedlings were produced using four doses of CRF (0, 4, 8, and 12 kg m-3) and four doses of remineralizer (0 %, 10 %, 20 %, and 30 %), in a 4 x 4 factorial scheme. At 180 days of seedling production, growth in height and stem diameter, shoot (SDB), root (RDB) and total biomass (TDB), and Dickson quality index (DQI) were evaluated. Results and conclusions: The use of remineralizer provided an increase in density and water retention capacity of substrates, as well as a reduction of macroporosity and total porosity. Combined with doses of 4 and 8 kg m-3, CRF contributed to the increase of biomass and DQI. The addition of 10 % remineralizer, associated with 4.0 kg m-3 CRF, provides adequate growth to produce M. scabrella seedlings. Above this percentage of remineralizer and CRF dose, species growth rate is reduced.

“…Among the available nutrients, studies show that yerba mate has a higher requirement for P>N>K>Mg>Ca, showing higher growth when using fertilizers that combine these nutrients [6,17]. In addition to the composition, the use of controlled-release fertilizers (CRF) has demonstrated for several species a better synchronization between plant physiological demands and nutrients availability [18][19][20][21][22][23], allowing for better use and lower leaching rate [24,25].…”

Given the lack of information on the use of controlled-release fertilizers in yerba mate seedlings production, this study aimed to evaluate growth and morphological characteristics of seedlings produced with two controlled-release fertilizers applied at different doses. We used seeds from a clonal seed orchard, which were sown in a commercial substrate based on peat and vermiculite, with Osmocote ® MiniPrill 3M (CRF 3M) and Basacote ® Plus 9M (CRF 9M) fertilizers, both in doses of 0, 2, 4, 6, 8, 10, and 12 kg m -3 . Seedling height and stem diameter were measured at 60, 90, 120, and 180 days after sowing and, at 180 days, shoot, root, and total biomass, tube withdrawal ease, and root aggregation. From these data, we calculated Dickson's quality index, technical efficiency, Height/Stem diameter ratio, and maximum technical efficiency dose. We verified values statistically superior to control treatment (0 kg m -3 ) in all variables in response to controlledrelease fertilizer 3M and 9M, demonstrating the viability of yerba mate seedling production using controlledrelease fertilizers. This is also evidenced through results obtained for growth in height and stem diameter. Although CRF 3M favored seedling growth, CRF 9M showed similar efficiency. The Osmocote ® MiniPrill 3M is more efficient than Basacote ® Plus 9M in most of the variables analyzed and has a lower input required to HIGHLIGHTS• Yerba mate seedlings are growth with controlled-release fertilizer.• Use of controlled-release fertilizer reduces the production costs.• The fertilizer 3M has a lower input required than fertilizer 9M.
