Granulated and Biosolid Fertilizers on the Quality of Schinus terebinthifolius Raddi Seedlings

Abstract

The objectives of this study were to evaluate substrates produced from the peach-palm agroindustry waste and sewage sludge as a source of nutrients for the production of Brazilian Peppertree seedlings (Schinus terebinthifolius Raddi), and to compare the performance of these substrates under various levels of slow release fertilizer for this species. Four levels of fertilizer were tested (0, 2.0, 4.0 and 6.0 g dm-3) in three types of substrates: BIOCPI = Sewage sludge + Peach-palm bark (1:1 v:v); BIOCPII = Sewage sludge + Peach-palm bark (1:2 v:v) and BIOCPIII = Sewage sludge + Peach-palm bark (1:3 v:v). Plant height, stem diameter, dry matter (shoot and root), height/diameter ratio, Dickson quality index and N, P, K, Ca, Mg, and S contents in the shoot were measured. The use of the substrates BIOCPII and BIOCPIII proved to be viable for the production of Brazilian Peppertree seedlings. Doses above 4.0 gdm-3 of granular fertilizer are recommended for better results.

Sewage sludge as substrate in Schinus terebinthifolia raddi seedlings commercial production

“…Seedlings produced with SS as substrate responded to CRF rates only for height in the present study, which can be considered unusual. The variation between the SS batches can explain the differences observed between the present study and others that tested SS as a substrate for tree seedlings 8 , 23 , 45 . The SS's physical, chemical, and biological characteristics are decisive in indicating its use as a substrate or not.…”

“…Other studies on Schinus terebinthifolia recommended CRF rates of 9.48 kg m −3 13-06-16 plus micronutrients 45 , 3 kg m −3 15-09-12 plus micronutrients 23 and above 4 kg m −3 15-09-12 8 . From the economic perspective, it is assumed that a rate of 3.0 kg m −3 of a CRF 09-15-12 with micronutrients would be adequate to produce Schinus terebinthifolia seedlings in the CS, reaching recommended values of height and diameter at 110 days after sowing.…”

“…Solid waste from sewage treatment is known as sewage sludge (SS) and has been tested and approved as a substrate for seedling production of forest species 7 , 8 . This material is being used in the Rio de Janeiro State Water and Sewage Company (CEDAE) nurseries, which produced more than 1,000,000 seedlings between 2015 and 2019 9 .…”

Decomposed Babassu Biomass: New Substrate for the Production of Jacaranda mimosifolia D. Don Seedlings

“…SH may be used as an estimate of the prediction of initial growth in the field (Gonçalves et al, 2014). Thus, it happened for DNH, which is, generally, observed in the evaluation of seedling survival capacity in the field (Silva et al, 2019). These results possibly occur due to the increase in the levels of nutrients that act in the growth and development of plants, playing a role in the physiological processes (Oosterhuis et al, 2013).…”

A Mixture of Arbuscular Mycorrhizal Fungi Favors Brazilian Pepper Seedlings Under an Intermediate Level of Soil Phosphorus

“…This species is naturally found in the Atlantic Forest (ARATO et al, 2017) and Caatinga regions (COSTA et al, 2015), and presents high decomposition rates of leaf litter (ARATO et al, 2017) as well as leaf structural aspects of xerophilic plants, such as multiple epidermal layers, a thick cuticle, and an abundance of hair and stomata, which prevent excessive drying (AZEVEDO; QUIRINO; BRUNO et al, 2015). These factors have stimulated seedling production experiments for the regrowth of native deforested areas in Brazil (SILVA et al, 2019), where S. terebinthifolius has shown high survival rates (RESENDE et al, 2015).…”
