Soil Classes and Regional Organic Residues Affect Nutrition, Morpho-Physiology and Quality of Copaiba Seedlings

Abstract

HIGHLIGHTS Copaiba seedlings show better growth response on substrate with carnauba residue. Higher volume of in natura or carbonized rice husks and goat manure such as seedlings. The classes of soils Gleissolo and Latossolo are more indicated in the formulation of the substrate. The mix of organic residues and soil classes increase the amounts of P, K, Ca and Mg in the aerial part.

ORGANIC RESIDUES IN THE COMPOSITION OF SUBSTRATES ENRICHED WITH BOKASHI BIOFERTILIZER FOR THE SUSTAINABLE PRODUCTION OF Copaifera langsdorffii SEEDLINGS

“…de Wit, Amaral et al seedlings (2016) they observed similar results for the height of plants produced in substrate with approximately 62% of this organic residue in its composition. Also, Damasceno et al (2019) observed increases in the height and quality of seedlings in which carnauba residue was used. The best results observed for plants cultivated in a substrate with carnauba residue in its composition reflect the greater wealth of nutrients present in this residue (Table 1).…”

Container volume and doses of maximum technical efficiency of controlled-release fertilizer on the morphological quality of Cordia alliodora seedlings in Roraima

“…According to Damasceno et al (2019), shoot dry mass indicates the rusticity of a seedling, and the highest values, obtained in plants grown in the 2.2 L container, with the DMTE of 5.82 g L 1 of CRF (Fig. 3A), represented more lignified and rustic seedlings, with greater guarantee for establishment and sur vival in the field.…”

Initial growth of zinnia seedlings in substrate with different proportions of biosolid

“…Shoot dry mass (SDM), root dry mass (RDM) and total dry mass (TDM) exhibited a quadratic response on the regression analysis, with maximum increments in dry biomass of 66.84%, 52.54% and 63.42% respectively, with the increase of biosolid in the substrate (Figures 2A,2B and 2C,respectively). According to Damasceno et al (2019), shoot dry mass is an indicator of hardiness in a seedling and the higher efficiency obtained in solar energy uptake by this trait for photosynthesis and photoassimilate production results in a higher total dry weight (Souza et al, 2020) Based on the results obtained for the root length (Figure 1C) correlated with the RDM (Figure 2B), it is possible to understand that there were a greater production in number of root apices by the plant, being in agreement with what was proposed by Afonso et al (2012), who report that roots with greater amount of dry mass tend to show a greater number of root apices, mainly as a result of the nutritional richness present in the substrate. Furthermore, Pêgo et al (2019) when evaluating the vigor and quality of Zinnia elegans seedlings produced in alternative substrates in trays of different cell sizes, found that the substrate obtained by composting agricultural waste provided the greatest increment in dry mass for the seedlings.…”
