1. Composition and mineralization of organic compost derived from composting of fruit and vegetable waste
ABSTRACT Fruit and vegetable waste can be used for the production of organic compost, which when mineralized can increase the availability of nitrogen. The objectives of this study were: (a) to produce compost from different ratios of fruit and vegetable waste, rice husk and poultry manure that meets the legislation on organic fertilizers and (b) to assess t

2. Sowing depth of annual ryegrass seed on different substrates as a vigor test
Resumo: Sementes de azevém com baixa qualidade fisiológica têm resultado em pastagens com inadequado estande de plantas para a cobertura do solo e, sobretudo, para a exploração forrageira. Neste sentido, o presente trabalho teve como objetivo propor um teste de vigor para sementes de azevém anual. Foram testadas profundidades de semeadura (0,5; 1,0; 1,

3. Economic and Financial Analysis of Tree Seedling Production Using Composted Biosolids Substrate
ABSTRACT The aim of this study was to evaluate production profitability of Croton urucurana and Cytharexyllum myrianthum seedlings produced in substrates composed of mixtures of composted biosolids and carbonized rice husk in different concentrations of nutrient solution. Seedlings were subjected to three doses of fertigation solutions. In order to check qua

4. Efficiency of the On-Farm Mycorrhizal Inoculant and Phonolite Rock on Growth and Nutrition of Schinus terebinthifolius and Eucalyptus saligna
ABSTRACT: The production of tree seedlings with high survival rate and growth is influenced by the substrate, which may be composed of biological and non-biological materials that help plant growth. The objective of this study was to evaluate the efficiency of a mycorrhizal inoculant on farm and the use of a potassic rock (phonolite) on growth and nutrition

5. Enraizamento adventício de justícia vermelha e sanquésia usando ácidos indolbutírico e húmico
Plant regulators, as well as bioactive fractions of the organic matter, can accelerate the development and increase the efficiency of adventitious rooting in ornamental plants. We evaluated rooting in the Brazilian red-cloak (Megaskepasma erythrochlamys) and sanchezia (Sanchezia nobilis) cuttings in response to application of indole-butyric acid (IBA) and hu

6. DISPONIBILIDADE HÍDRICA NA PRODUÇÃO DE GIPSOFILA (GYPSOPHILA PANICULATA) EM VASOS COM SUBSTRATO DE CASCA DE ARROZ CARBONIZADA / WATER AVAILABILITY ON GIPSOFILA (GYPSOPHILA PANICULATA) GROWING IN POTS WITH SUBSTRATE RICE HUSK CARBONIZED
Ornamental plants in general are highly susceptive to water deficiency, principally to the elevated soil water level variation that effects at a precarious and uneven final product development. The study was conducted on greenhouse at the Universidade Federal de Santa Maria, RS. It aimed to observe if rice husk ash substrate offers limitation to the pot cult

7. The effects of arbuscular mycorrhizal fungi inoculation on Euterpe oleracea Mart. seedlings.
With the objective of verifying the response of Euterpe oleracea Mart. seedling to seven arbuscular mycorrhizal fungi species, an experimental trial was carried out under greenhouse conditions. Seeds of E. oleracea were sown in carbonized rice husk. Germinating seeds were initially transferred to plastic cups, containing fumigated Reddish Yellow Quartz Sand

9. Extrato pirolenhoso no cultivo de orquídeas
The use of pyroligneous extract in the cultivation of plants is improvement of development. The effect of the use of different shot of pyroligneous extract in vegetative of two orchids of the gender Cattleya was studied in greenhouse. Used plants Cattleya intermedia Lindl and Cattleya loddigesii Lindl, grown in pots containing substrate composite coconut fib

10. Potencial de enraizamento de estacas lenhosas de espÃcies florestais da mata ciliar / Potential for rooting of wood cutting species from riparian forest
The bioengineering has been used for the containment of slopes and ravines on the banks of watercourses. One of its tools is the use of hardwood cuttings planted directly in the field, but this requires that species have local adaptation with large capacity for rooting. Thus, this study had the objective of study the propagation by cuttings of native woody f

11. Substratos alternativos ao xaxim para o cultivo de espécies do gênero Cattleya (Orchidaceae)
The use of alternatives beds for xaxim on culture of ornamental plants is a mean to contribute on environmental preservation, but it depends of studied vegetal specie and kind of ambience. Present work had the purpose to evaluate efficiency of different beds by vegetal origin, to grow species of orchids (Orchidaceae). Seedlings of Cattleya loddigesii, Cattle

12. Development of embryos and plantlets of Coffea arabica L. by direct Somatic Embryogenesis / Desenvolvimento de embriÃes e plÃntulas de (Coffea arÃbica L.) oriundas de embriogÃnese somÃtica direta
Coffee breeding programs have incorporated, by means of artificial crossings, genetic benefits for productivity and other characteristics of agronomic interest. The introduction of biotechnology methods to aid genetic breeding programs has demonstrated to be very much useful, mainly in perennial cultures, as it is the case with the coffee species. An importa
