“…Taub, Dutra et al (2016) observed similar responses for height, root dry mass and total dry mass, for which maximum growth occurred at the doses of 5.3, 7.7 and 8.5 g dm -3 and, later, such doses had their mean values dropped. Berghetti et al (2016) verified the effect of Osmocote® doses (15-09-12) on Cordia trichotoma seedlings, and also observed equivalent results to the present study, since the dose range which provided the best performance for the evaluated parameters oscillated between 6.1 and 5.4 g dm -3 .…”

Slow release fertilizers have become an alternative for better efficiency in substrate fertilization for seedlings production, however, there are not many studies approaching the use of such fertilizers in the production of native forest species seedlings. This work aimed to evaluate the effect of different doses of a slow release fertilizer (SRF) on the development and quality of the Inga heterophylla seedlings. The experiment was conducted in a vivarium with 50% of shade for a 150-day period. Randomized blocks were the chosen experimental design, constituted of four treatments and four replications, with twenty plants per experimental unit. The treatments were four doses of Osmocote® FLL (0, 4.1, 8.2 and 12.3 g dm-3) in NPK 15-09-12 formulation, with evaluated variables being the height of the seedling (H), collar diameter (CD), number of leaf pairs (NLP), leaf area (LA), aerial part dry mass (APDM), root dry mass, total dry mass (TDM) and Dickson quality index (DQI). All the evaluated parameters responded significantly to the SRF doses and fit the positive quadratic polynomial model. For all of the analyzed variables, results show that the best averages were obtained by using the doses between 5.7 and 6.5 g dm-3, but due to the quadratic response they presented a decrease in the mean values after doses which were superior to the maximum performance point of each characteristic.

“…Therefore, the dose of 2.0 g L -1 allowed greater growth in height and diameter at 240 DAT. Concerning robustness, a similar result of this study (Table 3) was obtained by Berghetti et al (2016), with Cordia trichotoma seedlings, a significant difference in RI was found only for recipient size (110 cm 3 and 180 cm 3 ) 210 days after sowing. CRF was able to supply the species nutritional demands through the evaluated period, which was showed as the absence of statistical difference between 1.8 L and 2.2 L recipients for DQI (Table 3).…”

The objective of this work was to evaluate seedlings quality of the tree species Agonandra brasiliensis under different doses of the controlled release fertilizer (CRF) Osmocote® and recipient volumes. The experiment was set up in a factorial design for two recipient volumes (1.8 L and 2.2 L) and five CRF doses (0.0; 0.5; 1.0; 2.0; and 3.0 g L-1 of substrate). Four repetitions of one plant each were used. After transplanting seedlings, stem height, stem collar diameter, and the robustness index (RI) were measured in a monthly basis during eight months. The highest seedlings growth was observed with the CRF Osmocote® dose of 2.0 g L-1 and recipients of 2.2 L. The treatment with CRF dose of 2.0 g L-1 in 240 days presented higher initial accumulated growth in height of A. brasiliensis seedlings (mean = 31.38 cm). Seedlings under the dose of 2.0 g L-1 presented 85.90% increase of stem height in relation to the control (substrate without CRF). CRF Osmocote® had positive effect on growth of A. brasiliensis seedlings. Growth was influenced by the different CRF doses and recipient volumes, both for the variables stem height and stem collar diameter and for the RI. The dose 2.0 g L-1 allowed greater accumulated growth in height and diameter in 240 days.

“…Incorporating slow-release fertilizer in addition to water-soluble fertilizers produced greater root biomass and root volume, compared to applying water-soluble fertilizers only, which is coincident with the results reported by Cortina et al [32], who noted that root growth in fertilized plants commonly increases when the phosphorus and nitrogen availability also increase, improving the ability of the plants to absorb water. Several authors have examined the favorable effects that increasing the dose of nutrients may have on growth and other desirable plant characteristics, both in the nursery and in the field [34,[62][63][64]. Controlled-release fertilizers minimize the loss of nutrients by leaching, due to their potential to supply nutrients in synchrony with the needs of the plant [65] and in this work the plant responses, expressed in morphological and physiological quality indices, confirmed these effects ( Table 3 and Figure 2).…”

Rooting substrate and fertilization are key components in the production of containerized seedlings, as they can influence the morphological and physiological characteristics of the plants, which in turn can impact outplanting performance. The objective of the study was to evaluate the effect of four substrates based on mixtures of peat moss (PM), composted bark (CB) and raw pine sawdust (PS), combined with two doses of controlled release fertilizer (CRF) and one non-fertilized control, on the growth of Pinus cembroides Zucc. in the nursery. The treatments were: M1: 50+25+25, M2: 25+25+50, M3: 25+50+25 and M4: 50+50+0 of PM+ CB+ PS (% by volume), respectively. Fertilizer treatments used a controlled release fertilizer (Multicote®): F1: 3 kg m−3 and F2: 6 kg m−3 and a control (WF: with no added fertilizer). The treatments were distributed in a randomized complete block design, with a factorial arrangement of 4 × 3 and six replications. The variables evaluated were: height, seedling diameter, dry biomass, Dickson Quality Index, N, P and K content. Regardless of the substrate, the high fertilizer dose (6 kg m−3) improved most morphological variables. In addition, the high fertilizer dose resulted in foliar N, P and K concentrations within recommended ranges for all substrates. The substrate containing only peat moss and composted bark (M4 + F1 and M4 + F2) had the best growth response. However, the substrate composed of 25% peat moss, 50% composted bark and 25% raw pine sawdust with the high fertilizer dose (M3 + F2) resulted in acceptable seedling growth, and may be preferred if the cost of the substrate is a concern to nursery manager.
