“…Substrates used in that study presented different characteristics according to proportions of components added to commercial substrate. Therefore, the characteristic of particles that compose them, such as size and shape, was one of the main factors that directly interfered with the arrangement of mixtures (Fermino et al, 2018).…”

Yerba mate is a Brazilian native species; its importance is due to cultural, environment, and economic factors. Species seedlings production needs to be improved, evaluating alternative substrates and containers. Therefore, we evaluated growth and quality of yerba mate seedlings produced on organic waste-based substrates in biodegradable and non-biodegradable containers. Commercial substrates based on pine bark (CS) and components based on sewage sludge (SS) and coal residue (granulometry from 1 to 3 mm - CR) were used. For each container, were prepared treatments with different substrate components: 75CS/25CR, 50CS/50CR, 25CS/75CR, 75CS/25SS, 50CS/50SS, 25CS/75SS, and CS. Substrates were submitted to physical and chemical analysis. The containers used were 110 cm³ polypropylene tubes, 500 cm³ polyethylene plastic bags, 460 cm³ paperpot®, and 460 cm³ TNT (non-woven fabric). Total height, stem diameter, shoot, and root dry biomass at the end of the seedlings production period were measured and total dry mass, Dickson quality index and height/diameter ratio were calculated. All containers used with commercial substrate provided satisfactory seedlings growth. The substrates showed distinct physical and chemical characteristics due to the addition of sewage sludge and coal residue, which resulted in higher pH and lower seedlings growth. Physical and chemical characteristics of substrates influenced growth and quality of yerba mate seedlings and the alternative substrates used in this study are not suitable to produce seedlings of the species on these conditions. The containers did not influence the variables used in this study.

“…Agricultural and industrial practices produce large amounts of wastes that can be rich in nutrients or have essential properties (aeration space, porosity and water availability) for plant cultivation (Vieira, 2014). Research is currently investigating sustainable and low-cost alternatives for seedling production (Mieth et al, 2018;Fermino et al, 2018). Thus, studies have focused on reusing waste for substrate formulation to recycle their nutrients and mitigate adverse environmental impacts (Araujo et al, 2017).…”

“…The seed is one of the residues from the industrial processing of peach, consisting of an almond used to extract cosmetic oil and has a high calorific value, while the pericarp is used as material for power generation (Diniz et al, 2004). Mieth et al (2018) and Fermino et al (2018) studied the peach kernel as a substrate component, as when crushed, it can be used to improve the substrate physical characteristics while reducing costs.…”

This study aimed to evaluate different container sizes and substrates formulated with agro-industrial residues to produce Handroanthus heptaphyllus and Schinus terebinthifolius seedlings. The experiment had a completely randomized design with four replications (48 seedlings each), in a factorial scheme (containers × substrates), with two containers (110 and 180 cm 3 ) and ten substrates (agro-industrial residues (crushed peach pits and peel rice) mixed with organic compost). Carbonized and hydrolyzed rice husk (CRH and HRH, respectively) were used. At 90 and 108 days after the emergence of the S. terebinthifolius and H. heptaphyllus seedlings, the morphophysiological attributes were evaluated. Considering the attributes evaluated in this study, the 180 cm 3 container promoted more significant seedling growth for both species. Substrates containing up to 20% CRH, HRH, or crushed peach pits (CPP) are indicated for S. terebinthifolius, and those with up to 30% CRH or 10% HRH or CPP are indicated for H. heptaphyllus.

“…An efficient substrate must contain the physical, chemical, and biological characteristics for plant development in a restricted environment, as well as meet the practical requirements of the production system in which it is inserted (Barrett et al, 2016). Substrate quality determines the management of other factors, such as irrigation and nutrition, and also influences the seedling production cycle in a variety of ways (Fermino et al, 2018).…”

“…Such characteristics are important as they determine the distribution of air, water and solid particles in substrates(Pascual, 2018).Despite the differences in physical and chemical characteristics, all materials used in this experiment could potentially be used as substrate components to produce seedlings of yerba mate, as all of them fitted in parameters used by other authors as adequate for seedlings production(Trigueiro & Guerrini, 2014;Kratz et al, 2017;Pascual, 2018). However, it is important to consider the ratio of the materials used as substrates components because different particle sizes and shapes of the substrate components may interfere with the arrangement of the mixtures and, consequently, in their physical characteristics(Fermino et al, 2018). Therefore, the decomposition and carbonization processes directly influenced the physical and chemical characteristics of the yerba mate residue and, consequently, altered the substrates in which these residues were used.Adding DYM to the substrate compositionGabira et al (2020) Industrial residues as substrate components... increases its density and, when in mixes with CF, microporosity also increases Simões et al (2012).…”

Ilex paraguariensis is an important forest species in Brazil. Recently, the development of new products has increased seedlings demand and consequently, the interest in new products to use as substrates like residues from industries. We aimed to evaluate the viability of using industrial residues as substrates to produce yerba mate seedlings. We formulated thirteen substrates with coconut fiber, carbonized and decomposed yerba mate industrial residues in different ratios, which were compared to two commercial substrates, in a completely randomized design. The stratified seeds were placed in 110 cm³ tubes filled with the substrates. Plants were kept in a greenhouse for 135 days, shade house (70%) for 30 days, and rustification area in full sunlight for 15 days, under fertigation after 30 days of sowing. We evaluated montlhy the survival, height, and stem diameter, and at the end of the production period, we evaluated shoot and root dry mass. From the data obtained, we calculated the total dry mass and ‘Dickson quality index’. The substrates formulated with coconut fiber and decomposed yerba mate industrial residue can be used to produce yerba mate seedlings, but it depends on the ratio of the substrate components. Substrates with higher total porosity and microporosity provided seedlings with biometric characteristics similar to those produced in commercial substrates. The carbonized yerba mate residue reduced seedling growth when used in a percentage equal to or higher than 50% in the substrate.
