“…Seedling morphological characteristics at the time of field planting directly affected their diameter at 24 months; however, substrate characteristics did not affect the initial growth of the seedlings. Seedling size is important for predicting the success of a plantation because it is directly related to the plant's capacity to overcome weed competition and develop new roots (Khanal et al, 2018;Riikonen & Luoranen, 2018). It should be noted that, compared with diameter, height seems to be much more dependent on environmental factors, such as weed competition and plant density (Resquin et al, 2018).…”

The objective of this work was to evaluate the survival and initial growth, in the field, of eucalyptus seedlings produced in different substrates. Eucalyptus benthamii seedlings produced in 36 substrates were evaluated in the field. The substrates consisted of mixtures, at different volumetric proportions, of: carbonized rice husk, charcoal with granulometry between 1.0-3.0 mm, charcoal with granulometry between 3.0-5.0 mm, coconut fiber, semi-decomposed pine bark, fine vermiculite, sewage sludge, and peat moss. At 1, 2, 3, 6, 12, 18, and 24 months after planting, survival, height, and diameter were determined. At 24 months after planting, height increment, diameter increment, transversal area, and basal area were also measured. The seedlings that showed 100% survival after 24 months under field conditions were those grown in the nursery in substrates with a higher proportion of fine vermiculite, sewage sludge, and peat moss, that is, in substrates with a higher microporosity. However, there is no effect of substrate characteristics on seedling initial growth in the field. A significant correlation is observed between the survival of seedlings at 6 months and their diameter at the end of the nursery period, evidencing the importance of this characteristic for the establishment of the plant in the field, regardless of the used substrate.

“…Evaluating the morphological and physiological characteristics of nursery plants provides an estimate of the survival and growth potential of those plants following outplanting [8,9]. Diameter is the morphological variable that most correlates with field survival [10,11], but other important variables are total dry weight and the Dickson quality index [12].…”

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.

“…The success of a forest plantation for commercial production or restoration purposes depends on seedling quality. Highquality seedlings enable rapid establishment with low mortality rates (Riikonen & Luoranen, 2018). Morphological parameters can be indicators of seedling quality, such as diameter, height, shoot and root dry weight, and shoot root ratio (Grossnickle & MacDonald, 2018a;2018b).…”

The success of seedlings establishment for commercial planting and forest restoration depends on the availability of nutrients during seedlings production. The objective was to evaluate the efficiency in controlled-release fertilizer use in Cordyline spectabilis seedlings production and what is the additional cost per seedling produced. Seedling production was performed with doses of 0.0 (control); 2.5; 5.0; 7.5; 10.0 and 12.5 kg m-³ of Basacote ® Plus 9M (16-08-12) controlled-release fertilizer added to the substrate. The experiment was placed in a greenhouse and we evaluated morphological parameters to determine seedlings growth. The dose of 10.7 kg m-3 provided a greater number of leaves (11.4) and leaf length (24.9 cm), higher values of shoot (4.64 g), root (2.32 g) and shoot root ratio (1.99) were obtained above 10.7 kg m-3 fertilizer. We recommend the use of 10.7 kg m-3 controlled-release fertilizer for seedlings production with an increase of R$ 0.05 per seedling produced.
