“…Ferreira et al (2015) suggest the use of agro-industrial residues in the composition of substrates for producing seedlings of forest species. This is aimed at reusing the nutrients contained in these materials and reducing the production cost, while also reusing these residues in order to minimize the impact caused by their disposal into the environment (Araújo et al 2017, Krause et al 2017.…”

The availability of single assai palm (Euterpe precatoria) seedlings with good quality is a fundamental requirement to expand the cultivation of the species. This study aimed to assess the use of fruit agro-industry residues as substrate for producing single assai seedlings. The experiment was carried out under nursery conditions, in a completely randomized design, with four replications and eight plants per plot. Fifteen treatments were evaluated: a commercial substrate, four dry and crushed agro-industrial residues (Brazil nut shell, acerola pit, assai pit and cupuassu peel) and ten combinations of these materials in the proportion of 1:1. The following variables were also measured: shoot height; stem diameter; number of leaves; shoot, root and total dry mass; and Dickson Quality Index score. The substrate formulated with Brazil nut shell + acerola pit stood out for promoting a higher growth and dry biomass, resulting in seedlings with a better quality. The pure assai pit residue was not efficient for producing seedlings, but it showed a good potential when mixed in equal proportion with other materials (e.g. Brazil nut shell and cupuassu peel).

“…Conclui-se que o sistema fechado é uma boa alternativa para a produção de tomate e preservar os recursos envolvidos no processo (como água e fertilizantes), reduzindo a poluição. of the most cultivated vegetables due to its profitability and its consumption (Krause et al, 2017).…”

“…Hydroponics is a technique used to grow plants in a combination of water and nutrients called nutrient solution (NS). This technology may have mechanical support for the plant, generally an artificial medium (substrate) that provides appropriate physical and chemical characteristics for plants (Steiner 1984;Krause et al, 2017). The use of hydroponics to produce vegetables in greenhouses is highly efficient in water use since losses due to evaporation and percolation are lower (Grewal et al, 2011, López et al, 2011.…”

The amount of water and fertilizers used in the production of vegetables, specifically tomatoes, is high. This study was carried out to determine water and fertilizers use efficiency in closed and open hydroponic systems for tomato production under greenhouse conditions. Two treatments with eight replications were assessed; each replication consisted of 67 pots with two plants each. One treatment was a closed hydroponic system (with nutrient solution recirculation), and the other was an open hydroponic system (with non-recirculating nutrient solution). We quantified the amounts of water and fertilizers applied, as well as the losses (drained nutrient solution), in the two treatments during the entire cycle of tomato. In the nutrient solution (NS) we also measured electric conductivity (EC), pH, volume applied, and volume drained, and total weight of fruits (25 pickings). There were no significant differences between the two treatments on fruit production. Water use efficiency was 59.53 kg/fruit/m3 for the closed system and 46.03 kg/fruit/m3 in the open system. In comparison to the open system, the closed system produced 13.50 kg more fruit per cubic meter of water, while 10.31 grams less fertilizers per kilogram of fruit produced were only applied. Water and fertilizers use efficiency were higher in the closed system, by 22.68% and 22.69%, respectively. More efficiency was obtained in the closed system, regarding the open system. We concluded that the closed system is a good alternative to produce tomato and preserve the resources involved in the process (like water and fertilizers), thus reducing pollution.

“…Within the production chain of fruit and vegetables, a decisive factor for obtaining quality seedlings is the type of substrate used. The substrate must provide adequate air and water supply to the root system (SANTOS JÚNIOR et al, 2014), as well as providing sufficient nutrient content and good cation exchange capacity (OLIVEIRA; HERNANDEZ; ASSIS JÚNIOR, 2008), and being easy to handle, of low cost and of high availability (KRAUSE et al, 2017).…”

Production of Cucumber Seedlings in Alternative Substrates With Different Compositions of Agricultural Residues

et al. 2018

Studies on the use of agricultural residues as an alternative to commercial substrates have become fundamental tominimising the risk of environmental contamination resulting from inadequate disposal, as well as reducing seedling production costs. This research involved an evaluation of growth variables and quality of cucumber seedlings produced in substrates with different compositions of agricultural waste with a view to providing substitutes for commercial substrate. The experiment was based on a completely randomised design, with six treatments and ten replicates. There were five treatments with increasing proportions of moinha/decreasing proportions of carbonized rice husk (0/40, 10/30, 20/20, 30/10 and 40/0%) and fixed proportions of coconut fibre (15%), eggshell (5%), pine bark (40%), and one commercial substrate treatment as the control (Bioplant®). The variables evaluated were: electrical conductivity of the substrate, plant height, stem diameter, number of leaves, Dickson quality index (DQI) and dry matter of roots and above ground parts. Results show that alternative substrates can replace commercial substrate without impairing the quality of cucumber seedlings. However, the substrate containing 40% of moinha, 0% of rice husk, 15% of coconut fibre, 5% of eggshell and 40% of pine bark resulted in the highest values for all evaluated variables and appears to be the most promising alternative substrate for the production of cucumber seedlings.
