Resumo: | The tung (Aleurites fordii) has received attention in recent years as a promising source of raw material for biodiesel production. For this crop to start production after three years of planting, appears in the first year of planting tung the possibility of growing oleaginous in tree-based intercropping (TBI). Crops such as crambe, sunflower and peanuts have the potential to use in TBI. The biodiesel generated from these oilseeds is a renewable fuel that the CO2 emitted in combustion was previously set in photosynthesis during plant growth whithout any net emissions of this gas. However, emissions of greenhouse gases (GHG) occur during cultivation of oilseeds, aspect that can reduce the positive effect of the use of biodiesel on GHG emissions into the atmosphere. The objective of this study was to quantify the emissions of N2O and CH4, yield and oil and partial (p) and total (t) global warming potential (GWP) in system with oleaginous cutlived in TBI with tung. Four cropping systems were evaluated: crambe/sunflower/crambe (AB/SU/AB) fertilized with organic manure (FOM) to base in poultry litter (PL); crambe/sunflower/crambe (AB/SU/AB) fertilized with mineral fertilizer (FMF); oat + vetch / peanut / oat + vetch (O+V / PE /O+V), grown without of the use of fertilizer; and fallow / fallow / fallow (F). Emissions of N2O and CH4, GWP and yield were evaluated. The different cropping systems in TBI with tung had accumulated emission of N2O-N higher in 240-307% compared to treatment F. The different N sources (urea and CF) did not influence the cumulative emissions of N2O-N. The grain yield of AB and SU did not differ between treatments with FOM and FMF. The PE showed grain yield 1.4 times the SU+FMF and SU+FOM. When the GWP was performed considering each crop, it is observed that the AB and SU crops with FMF showed the highest values of GWPp compared to other crops. In these systems the emissions of N2O-N and mineral fertilizer (NPK) were the main sources of CO2 eq. for the GWPp. In all systems was observed reduction in soil C stocks after 1.4 years of conducting the experiment. Thus the C soil was the largest contributor to GWPt on all systems, followed by N2O. The cropping systems with AB and SU fertilized with FOM and FMF showed lower values of the GWPt and smaller ratios GWPt per unit of produced grains and oil, indicating that these systems have potential for use in TBI with tung. |

Por essa cultura iniciar a produção após três anos do plantio, surge nos primeiros anos do plantio do tungue a possibilidade do cultivo de oleaginosas intercalares em sistema agroflorestal (SAF). Culturas como o crambe, girassol e amendoim apresentam potencial para compor esses sistemas. O biodiesel gerado a partir dessas oleaginosas é um combustível renovável em que o CO2 emitido na combustão foi previamente fixado na fotossíntese durante o crescimento da planta não havendo desta forma emissões líquidas desse gás. No entanto, emissões de gases de efeito estufa (GEE) ocorrem durante o cultivo das oleaginosas, aspecto que pode diminuir o efeito positivo do uso do biodiesel sobre a emissão de GEE para a atmosfera. O objetivo deste estudo foi quantificar as emissões de N2O e CH4, o rendimento de grãos e o potencial de aquecimento global (PAG) parcial (p) e total (t) em sistemas de culturas oleaginosas intercalares ao tungue em solo Argissolo. Foram avaliados quatro sistemas de cultivo: crambe/girassol/crambe (CR/GI/CR) fertilizados com adubação mineral (ADM); crambe/girassol/crambe (CR/GI/CR) fertilizados com adubação orgânica (ADO) a base de cama de frango (CF); aveia+ervilhaca/amendoim/aveia+ervilhaca (A+E/AM/A+E), cultivados sem o uso de fertilizante; e pousio/pousio/pousio (P). Foram avaliadas as emissões de N2O, CH4, PAG e o rendimento de grãos. Os diferentes sistemas de cultivo nas entrelinhas do tungue apresentaram emissão acumulada de N-N2O superior em 240 a 307% em relação ao tratamento P. As diferentes fontes de N (CF e ureia) não influenciaram nas emissões acumuladas de N-N2O. O rendimento de grãos do CR e GI não diferiram entre os tratamentos com ADO e ADM. O AME apresentou rendimento de grãos 1,4 vezes superior ao GI+ADM e GI+ADO. Quando o PAG foi realizado considerado cada cultivo, observou-se que o CR e o GI cultivados com ADM apresentaram os maiores valores de PAGp em relação aos demais cultivos. Nesses sistemas as emissões de N-N2O e a fertilização mineral (NPK) foram as principais fontes de CO2 eq. para o PAGp. Em todos os sistemas foi observado redução dos estoques de C no solo após 1,4 anos de condução do experimento. Com isso o C do solo foi o maior contribuidor para o PAGt em todos os sistemas, seguido pelo N2O. Os sistemas de cultivo com CR e GI fertilizados com ADO e ADM apresentaram os menores valores de PAGt e as menores relações de PAGt por unidade de grãos e óleo produzidos, indicando que esses sistemas apresentam potencial para uso em SAF com o tungue.Coordenação de Aperfeiçoamento de Pessoal de Nível Superiorapplication/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em Ciência do SoloUFSMBRAgronomiaGases de efeito estufaPotencial de aquecimento globalOleaginosasBiodieselGreenhouse gasesGlobal warming potentialOilseedsBiodieselCNPQ::CIENCIAS AGRARIAS::AGRONOMIA::CIENCIA DO SOLOEmissão de gases de efeito estufa e potencial de aquecimento global em sistemas de culturas intercalares ao tungue (Aleurites fordii)Greenhouses gas emission and potential of global warming in intercropping crop systems of tung (Aleurites fordii)info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisGiacomini, Sandro Joséhttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4794885J2Vieira, Frederico Costa Beberhttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4762866H8Souza, Eduardo Lorensi dehttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4711989Z2http://lattes.cnpq.br/0432603862453233Ramires, Maiara Figueiredo500100100005400500300300500419b5a2f-20df-408a-a156-d652293f4a737c4b9b8e-6916-4a99-a515-550707219f9aae163f56-99be-4eb6-bb00-10deaa26ee8a962d0006-3050-449b-bac4-1dd7959e1a13info:eu-repo/semantics/openAccessreponame:Manancial - Repositório Digital da UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALRAMIRES, MAIARA FIGUEIREDO.pdfapplication/pdf1644570http://repositorio.ufsm.br/bitstream/1/5591/1/RAMIRES%2c%20MAIARA%20FIGUEIREDO.pdfcad0c4e1f23a2f3e18bb91e66e3810a4MD51TEXTRAMIRES, MAIARA FIGUEIREDO.pdf.txtRAMIRES, MAIARA FIGUEIREDO.pdf.txtExtracted texttext/plain169109http://repositorio.ufsm.br/bitstream/1/5591/2/RAMIRES%2c%20MAIARA%20FIGUEIREDO.pdf.txt9131849c4a5c851fa53212ed5e99418bMD52THUMBNAILRAMIRES, MAIARA FIGUEIREDO.pdf.jpgRAMIRES, MAIARA FIGUEIREDO.pdf.jpgIM Thumbnailimage/jpeg5361http://repositorio.ufsm.br/bitstream/1/5591/3/RAMIRES%2c%20MAIARA%20FIGUEIREDO.pdf.jpg23b052e1e9c275d17922bd9462d6351aMD531/55912017-07-25 11:17:31.387oai:repositorio.ufsm.br:1/5591Repositório Institucionalhttp://repositorio.ufsm.br/PUBhttp://repositorio.ufsm.br/oai/requestopendoar:39132017-07-25T14:17:31Manancial - Repositório Digital da UFSM - Universidade Federal de Santa Maria (UFSM)false |
