Resumo: The quantification of the spatial variability of forage biomass production, vegetation indices and soil properties can help in pasture management practices such as rotation, nutrient management and yield forecast. The objective of the present work was to estimate the biomass of winter pastures through the Normalized Difference Vegetative Index (NDVI) obtained with an active proximal sensor. The experiment was conducted in the field, 2019 harvest in the municipality of Vacaria, Rio Grande do Sul, in the experimental area of Campus 2 of the University of Caxias do Sul. Weekly assessments were carried out to monitor pasture growth, measuring height using a graduated ruler and NDVI readings using a Flexum, Falker terrestrial equipment. Seven treatments were tested, namely: T1: Azevem LE 284; T2: Azevem KLM 138; T3: Azevem Winter Star; T4: Oat IAPAR 61; T5: Supreme Oats; T6: Milton oats; T7: Oat and ryegrass intercropping. The experimental design was in randomized blocks, with four replications of each treatment. The evaluated variables were determination of biomass through the NDVI index and height. The results showed a positive linear correlation between NDVI and height. In the regression analysis, a coefficient of determination R² of 0.3785 was found between NDVI and height. The results indicated that the use of the NDVI index with the active proximal sensor can be a promising tool in estimating the biomass of winter pastures, up to the first cut.

O objetivo do presente trabalho foi estimar a biomassa de pastagens de inverno através do Índice Vegetativo da Diferença Normalizada (NDVI) obtido com sensor proximal ativo. O experimento foi conduzido a campo, safra 2019 no município de Vacaria, Rio Grande do Sul, na área experimental do Campus 2 da Universidade de Caxias do Sul. Foram realizadas avaliações semanais para acompanhamento do crescimento das pastagens, realizando-se medições da altura por meio de régua graduada e leituras de NDVI através de equipamento terrestre Flexum, Falker. Foram testados sete tratamentos, sendo eles: T1: Azevem LE 284; T2: Azevem KLM 138; T3: Azevem Winter Star; T4: Aveia IAPAR 61; T5: Aveia Suprema; T6: Aveia Milton; T7: Consórcio de aveia e azevem. O delineamento experimental foi em blocos casualizados, com quatro repetições de cada tratamento. As variáveis avaliadas foram determinação de biomassa através do índice de NDVI e altura. Os resultados demonstraram correlação linear positiva quando entre NDVI com altura. Na análise de regressão encontrou-se coeficiente de determinação R² de 0,3785 entre NDVI e altura. Os resultados indicaram que a utilização do índice NDVI com o sensor proximal ativo pode ser uma ferramenta promissora na estimativa de biomassa de pastagens de inverno, até o primeiro corte.porUniversidade Federal de Santa MariaColégio Politécnico da UFSMPrograma de Pós-Graduação em Agricultura de PrecisãoUFSMBrasilAgronomiaAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessPecuária de precisãoForragemSensoriamento remotoPrecision livestockFodderRemote sensingCNPQ::CIENCIAS AGRARIAS::AGRONOMIAUso do NDVI para estimativa da biomassa de pastagens de inverno no município de Vacaria-RSNDVI use for estimation of winter pasture biomass in Vacaria, RSinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisSanti, Antônio Luishttp://lattes.cnpq.br/6223011493102530Vian, André LuisBueno, Marcio Eduardo Boeirahttp://lattes.cnpq.br/9921958301011591Lima, Caroline Silveira de50010000000960060060060060026e69663-7809-4435-8e7a-419ac889c5f3097e8daa-b996-4b95-813e-20b6e72a8b2c0f9f02b7-bbc3-4f88-ad0e-8c5f5c49b0c7571da25a-977c-47c6-8d3c-dc3d27e11529reponame:Manancial - Repositório Digital da UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALDIS_PPGAP_2023_LIMA_CAROLINE.pdfDIS_PPGAP_2023_LIMA_CAROLINE.pdfDissertação de mestradoapplication/pdf781646http://repositorio.ufsm.br/bitstream/1/30610/1/DIS_PPGAP_2023_LIMA_CAROLINE.pdfe42c05e4f001268373fd5cd7df9206ebMD51LICENSElicense.txtlicense.txttext/plain; charset=utf-81956http://repositorio.ufsm.br/bitstream/1/30610/3/license.txt2f0571ecee68693bd5cd3f17c1e075dfMD53CC-LICENSElicense_rdflicense_rdfapplication/rdf+xml; charset=utf-8805http://repositorio.ufsm.br/bitstream/1/30610/2/license_rdf4460e5956bc1d1639be9ae6146a50347MD521/306102023-11-21 16:24:26.922oai:repositorio.ufsm.br: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ório Institucionalhttp://repositorio.ufsm.br/PUBhttp://repositorio.ufsm.br/oai/requestopendoar:39132023-11-21T19:24:26Manancial - Repositório Digital da UFSM - Universidade Federal de Santa Maria (UFSM)false
