“…For vermiculite, the low performance as a substrate may be related to its high content of magnesium and iron which may have affected the calcium magnesium ratio of the medium and absorption of calcium and other nutrients by the plant. Caldeira et al (2013) suggest that vermiculite needs balancing of essential nutrients and should be used in conjunction with other material, preferably of organic origin, in order to promote aeration and porosity to other less porous substrates, in agreement with the results found in the experiment, where the addition of dry coconut powder to vermiculite promoted better results in the analyzed characteristics when compared to the use of vermiculite substrate without addition of other materials.…”

The transition from heterotrophism to autotrophism in acclimatization is a delicate process for most species. The objective of this work was to evaluate combinations of regional substrates of the Brazilian Northeast in the acclimatization and morphological development of minirose (Rosa chinensis 'Minima') seedlings. The experiment was carried out in a greenhouse using seedlings with 30 days of in vitro culture. The treatments were constituted by: 1) dry coconut powder; 2) 75% dry coconut powder + 25% rice husk; 3) 50% dry coconut powder + 50% rice husk; 4) 75% dry coconut powder + 25% charcoal rice husk; 5) 50% dry coconut powder + 50% carbonized rice husk; 6) 100% vermiculite; 7) 50% vermiculite + 50% dry coconut powder; 8) commercial substrate; 9) 75% sand + 25% dry coconut powder and 10) 50% sand + 50% dry coconut powder. After 21 days, the following characteristics were evaluated: survival percentage, leaf number, shoot height, dry matter of shoot and root and total dry matter. The regional materials tested showed a good choice of substrates to be used in the acclimatization of minirose seedlings. The vermiculite presented the worst results in the characteristics evaluated. Dry coconut powder as substrate should be used in mixtures with other materials to provide better acclimatization conditions. The use of 50% dry coconut powder + 50% rice husk provided a best development and growth of minirose seedlings (Rosa chinensis 'Minima') than other tested substrates

“…This links up the observations of Caldeira CALDEIRA JUNIOR et al, 2009 andCALDEIRA et al, 2013 found that on the field the best results in the survival of eucalyptus seedling are those substrates containing sewage sludge. These authors also noted that 2/1 of GPDM/RDM is a good balance for the growth of plants.…”

Abstract. We examine in this study a possibility of use the biodiesel industry waste as a source of nutrients for the production and development of seedlings seems like a very good option. We added the diatomaceous earth residues of Biodiesel with sludge from urban wastewater treatment or manure to stimulate the activity of soil bacterial. The Dickson Quality Index (DQI) values Eucalyptus Camaladulensis and Morus Alba seedlings growing in test substrates with sewage sludge and diatomaceous earth are all higher than the recommended minimum value of 0.2. The treatments with manure and diatomaceous earth do not meet the desired quality standard. The Eucalyptus Camaladulensis and Morus Alba seedlings have good growth in substrates containing sewage sludge and diatomaceous earth than only the commercial substrate. They can use up to 50% by volume of the substrate without compromising the seedlings quality with a reduction of cost of seedlings production.

“…According to Caldeira et al (2013), the SDM/RDM ratio is lower in environments of lower fertility and may be considered as a strategy of the plant, which invests in root growth instead of shoot growth to absorb as much as nutrients as possible under that condition. The same behavior was observed in this experiment, in which the lowest values of SDM/RDM were found in the treatment with commercial substrate.…”

A B S T R A C TThis study aimed to verify the potential of urban solid wastes as substrate for production of seedlings of Lafoensia pacari. Five treatments were tested, four with solid wastes and one standard substrate, namely: sewage sludge from Alegria Wastewater Treatment Plant (WTP); sewage sludge from Ilha do Governador WTP; sewage sludge from Sarapuí WTP; domestic garbage compost (Fertlurb); and a commercial substrate made of biostabilized pine bark (standard substrate). The wastes received 20% (in volume) of shredded coconut fiber. At 105 days after sowing, the seedlings were evaluated for different quality parameters. Seedlings produced with Sarapuí WTP sewage sludge showed the best results in all the parameters, followed by seedlings produced with sewage sludge from Alegria and Ilha do Governador WTPs, which did not differ. Seedlings produced with domestic garbage compost showed satisfactory results, higher than the ones observed for seedlings produced with commercial substrate. The urban solid wastes with 20% of coconut fiber showed high potential and can be recommended for the composition of substrate in the production of Lafoensia pacari seedlings.Resíduos sólidos urbanos na produção de mudas de Lafoensia pacari R E S U M O Objetivou-se, neste trabalho, verificar o potencial de resíduos sólidos urbanos como substratos na produção de mudas de Lafoensia pacari. Cinco tratamentos foram testados dentre os quais quatro resíduos urbanos e um substrato padrão, sendo: lodo de esgoto da Estação de Tratamento de Esgotos (ETE) Alegria; lodo de esgoto da ETE Ilha do Governador; lodo de esgoto da ETE Sarapuí; composto de lixo urbano (Fertlurb) e substrato comercial à base de casca de pinheiro bioestabilizada (substrato padrão). Foram acrescidos, aos resíduos, 20% em volume de fibra de coco triturada; aos105 dias após a semeadura avaliaram-se as variáveis referentes à qualidade de mudas; as mudas produzidas com substrato à base lodo de esgoto da ETE Sarapuí apresentaram os melhores resultados em todas as variáveis, seguidos pelas produzidas com os lodos das ETE Alegria e Ilha do Governador, que não diferiram entre si. As mudas produzidas com composto de lixo urbano apresentaram resultados satisfatórios e superiores ao observado nas mudas produzidas com substrato comercial. Os resíduos sólidos urbanos acrescidos de 20% de fibra de coco apresentaram potencial elevado podendo ser recomendados para a composição de substratos na produção de mudas de Lafoensia pacari.
