Sá,Mariangela Facco de; Gonçalves,Ricardo Aymay; Marder,Cristiana; Baldissera,Matheus Dellamea; Oliveira,Camila Belmonte de; Noll,Jessica Caroline Gomes; Silva,Filipe; Monteiro,Silvia Gonzalez.
ABSTRACT: Liquid pig manure (LPM) is widely used as a compost fertilizer for vegetable crops destined for human consumption. However, these wastes may contain parasites eggs, such as the nematode Ascaris suum, that pose serious health risks to humans. We attempted to determine the most appropriate technique for recovering A. suum eggs from LPM compost. Samples were collected from two waste sources during composting, including 23 samples containing LPM, sawdust, and wood shavings, and 14 samples of LPM alone-both in triplicate. Samples were analyzed using several different recovery methods. Recovery of eggs by the modified Bailenger method with adaptations was significantly more effective and recovered 57% more eggs than by the modified Bailenger method...

Allelopathic Activity of Crop Residue Incorporation Alone or Mixed Against Rice and its Associated Grass Weed Jungle Rice (Echinochloa colona [L.] Link) Chilean J. Agric. Res.
Khaliq,Abdul; Matloob,Amar; Ata Cheema,Zahid; Farooq,Muhammad.
Weed suppression is one of the several benefits achieved by soil incorporation of crop residues and such suppression is believed to be allelopathic in nature. The allelopathic potential of different crop residues: viz. sorghum (Sorghum bicolor [L.] Moench), sunflower (Helianthus annuus L.), brassica (Brassica campestris L.) was evaluated in rice (Oryza sativa L.) and jungle rice (Echinochloa colona [L.] Link). Chopped crop residues were soil-incorporated alone and mixed at 6 g kg-1 soil (12 t ha-1) and compared with a control without residues. Soil incorporation of residues substantially delayed germination of jungle rice. The time to start germination, time to 50% emergence, mean emergence time, emergence index, and final germination percentage were all...

Allelopathic Effect of Some Associated Weeds of Wheat on Germinability and Biomass Production of Wheat Seedlings Planta Daninha
ZOHAIB,A.; TABASSUM,T.; ANJUM,S.A.; ABBAS,T.; NAZIR,U..
ABSTRACT: Weeds associated with crops may impose their phytotoxic effects on crop plants through the release of their allelochemicals and hence seriously reduce crop productivity. The present study was conducted to investigate the allelopathic effect of water soluble phenolics of weeds associated with wheat crop (Vicia sativa, Trigonella polycerata, Lathyrus aphaca, Medicago polymorpha, Melilotus indica) on germinability and biomass production of wheat seedlings by using their water extracts at 2.5% (w/v) and 5% (w/v) concentrations and residues of the same weeds with 0, 15 and 30 d decomposition periods at 2% (w/w) concentration. The results showed that the water extracts of M. indica and V. sativa at 5% concentration imposed the most inhibitory effect on...

Allelopathic effects of Rhynchosia capitata on germination and seedling growth of mungbean Planta Daninha
Ali,H.H.; Tanveer,A.; Nadeem,M.A.; Javaid,M.M.; Kashif,M.S.; Chadhar,A.R..
Experiments were conducted to evaluate the allelopathic influence of Rhynchosia capitata on germination and seedling growth of mungbean (Vigna radiate) along with identification of the phytotoxic substances responsible for this activity. Water extracts of root, shoot, leaf, fruit and whole plant were prepared by soaking them in water in a ratio of 1:20 (w/v) for 24 h. All the extracts affected germination and seedling growth of mungbean, but higher inhibition was seen with R. capitata leaf water extracts. A linear decrease in the germination characteristics of mungbean was observed with the decrease in the concentration of leaf extract from 5% to 1%. The soil-incorporated residues (1-4% w/w) of R. capitata stimulated the growth of root and hypocotyl at low...

Allelopathic Influence of Residues from Sphagneticola trilobata on Weeds and Crops Planta Daninha
HERNÁNDEZ-ARO,M.; HERNÁNDEZ-PÉREZ,R.; GUILLÉN-SÁNCHEZ,D.; TORRES-GARCIA,S..
The allelopathic effect studied in many cultures has currently generated great expectations that displayed a natural and environmentally friendly tool for weed management using bioherbicides. The objective of this work was to assess allelopathic influence of residues of S. trilobata on the germination and growth of weeds, as well as their relation with some crops and effects on soil properties. Results show that residues from S. trilobata have inhibited the germination of weeds (31.6 - 72%), increasingly with the applied dose. All residue doses of this specie have inhibited dicotyledonous germination, but only maximum concentration has affected monocotyledons. The residues did not affect onion germination, but stimulated it in radish and tomato, while the...

Bacillus thuringiensis production using cassava liquid waste (manipueira) as a fermentation substrate. Repositório Alice
MORAES, I. O.; CAPALBO, D. M. F.; MORAES, R. O.; BIANCHI, V. L. del; CONTI, H. H..
In developing countries the search for inexpensive substrates to grow useful microorganisms is a desirable way to get new and safe products to protect man against insect pest losses. Bacillus thuringiensis is an entomopathogenic bacteria, which by fermentation produces endo- or exotoxins to be used against Lepidoptera or Diptera, resp. These are insect pests of economic importance in developing countries, mainly in Brazil, where 60% losses in agriculture are caused by this type of pest. Our research group has been working with B. thuringiensis since 1970; and many papers have been published on the processes, culture media composition and available substrates, culture and operational conditions, equipment and so on. Many residues and waste waters were tried...

Characterization and use of swine deep bedding ashes in cementitious composites REA
Oliveira,Débora C. G. de; Rodrigues,Michelle S.; Santos,Sérgio F. dos; Savastano Junior,Holmer.
The deep bedding is a swine alternative production, especially in the finishing phase, whose byproduct can be recycled, reducing the environmental impact. The objectives of this study were to characterize the ash coming from the controlled burning of the swine deep bedding (SDBA) based on rice husk, and to evaluate their performance in composites as a partial substitute for Portland cement (PC). To measure the differences between SDBA and rice husk ash (RHA) as a reference, we have characterized: particle size distribution, real specific density, x-ray diffraction, electrical conductivity, scanning electron microscopy, chemical analysis and loss on ignition. Samples were prepared for two experimental series: control, and another one with the partial...

Chemical composition of flours made of residues from the king palm (Archontophoenix alexandrae) industry BABT
Vieira,Manoela Alano; Podestá,Rossana; Tramonte,Karina Cardoso; Amboni,Renata Dias de Mello Castanho; Simas,Karina Nunes de; Avancini,Sandra Regina Paulon; Amante,Edna Regina.
Residues from King palm (Archontophoenix alexandrae) processing were used for the production of flours, which were then chemically characterized. The protein content in these flours ranged from 3.62 to 9.75 g/100g and was higher in sifted leaf flour (SLF). The dietary fiber contents varied from 64 to 72 g/100g. These values were high when compared to those of flours used in human nutrition. Analysis of anti-nutritional factors showed phytate contents to be below the levels that affected the bioavailability of minerals in human diet. Tannin contents were compatible with those found in legumes, between 0 and 2000 mg/100g. These flours showed high mineral content, which suggested a possibility for them to be used as food supplement. However, the...

DESTINO DE RESÍDUOS DE INCUBATÓRIOS DA AVICULTURA NO ESTADO DE SÃO PAULO: ADEQUAÇÃO À LEGISLAÇÃO E POSSIBILIDADE DE USO ECONÔMICO AgEcon
Kobashigawa, Estela; Murarolli, Rafael Azevedo; Gameiro, Augusto Hauber.
Em decorrência do contínuo crescimento da avicultura no Brasil, tanto de corte quanto de postura, ocorre concomitantemente um aumento de alojamento de matrizes e, portanto, dos resíduos formados pela incubação de ovos férteis. Em contrapartida no Estado de São Paulo criou-se, recentemente, a Lei no 12.300, de 16 de março de 2006, obrigando os incubatórios a dar um destino adequado aos seus resíduos. Devido ao custo de manejo dos resíduos, tem-se a oportunidade de se estudar novas alternativas, que possam eventualmente agregar valor ao produto, possibilitando sua comercialização. Objetivou-se neste estudo analisar quais os destinos dados aos resíduos de incubatórios no Estado de São Paulo. Um grupo de cinco empresas representativas foi entrevistado....
