Resumo: | The agro-industrial residues have great potential for providing silicon (Si) and other nutrients for crops. The objective of this work to assess the supply of silicon for organic waste agribusiness, and to evaluate the influence of this nutrient in the accumulation of nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg ) and sulfur (S) in maize. We analyzed the accumulation of silicon in the leaves and stems of the plant and the effect of these sources in stem diameter, the height and mass of dry corn plant, as well as the accumulation of N, P, K, Ca, Mg and S in corn leaves provided by agro-industrial residues and by levels of silicon used. The experiment was conducted in a greenhouse in a completely randomized design (4x3) + 1. We evaluated three sources organic agribusiness (bagasse ash from sugar cane filter cake rotary sugarcane and rice hulls), and for the supply of silicon also evaluated the mineral source (calcium silicate PA); three strengths of SiO2 (175 kg ha-1, 350 kg ha-1 and 700 kg ha-1) and additional treatment (control), which received no SiO2. The sources and doses of SiO2 did not affect the mass of dried corn plants. However, the addition of SiO2 dose provided an increase in the diameter of stem of the maize plant. The rice hulls was more efficient among all treatments in Si supply to the corn crop. The supply of Si favors the absorption and consequent accumulation of potassium and phosphorus from the corn plant. There was no relationship between the supply of Si and Mg and S uptake by corn plant. Finally, there was no relationship between the accumulation of Si and the reduction of leaf N in corn plants. |

Objetivou-se, com esse trabalho, avaliar o fornecimento de silício por resíduos orgânicos agroindustriais, e avaliar a influência desse nutriente no acúmulo de nitrogênio (N), fósforo (P), potássio (K), cálcio (Ca), magnésio (Mg) e enxofre(S) na planta de milho. Foi analisado o acúmulo de silício nas folhas e nos colmos da planta e o efeito dessas fontes no diâmetro do colmo, na altura e na massa da planta de milho seca, assim como o acúmulo de N, P, K, Ca, Mg e S nas folhas de milho proporcionado pelos resíduos agroindustriais e pelas doses de silício utilizadas. O experimento foi instalado em casa de vegetação no delineamento experimental inteiramente casualizado (4x3) + 1. Foram avaliadas três fontes orgânicas agroindustriais (cinza de bagaço de cana-de-açúcar, torta de filtro rotativo de cana-de-açúcar e casca-de-arroz carbonizada), e para o fornecimento de silício também avaliou-se a fonte mineral (silicato de cálcio P.A.); três dosagens de SiO2(175 Kg ha-1, 350 Kg ha-1 e 700 Kg ha1) e o tratamento adicional (testemunha), o qual não recebeu SiO2. As fontes e doses de SiO2 não influenciaram a massa das plantas secas de milho. Entretanto, o acréscimo das doses de SiO2 proporcionou o aumento no diâmetro de colmo da planta de milho. A casca-de-arroz carbonizada mostrou-se mais eficiente entre todos os tratamentos no fornecimento de Si para a cultura do milho. O fornecimento de Si favoreceu a absorção e consequente acúmulo de P e K pela planta de milho. Não se observou relação entre o fornecimento de Si e a absorção de Mg e S pela planta de milho. Por fim, não houve relação entre o acúmulo de Si e a redução do N foliar nas plantas de milho.Financiadora de Estudos e Projetosapplication/pdfporUniversidade Federal de São CarlosPrograma de Pós-Graduação em Agroecologia e Desenvolvimento Rural - PPGADR-ArUFSCarBRAgriculturaBagaço de canaTorta de filtroCinza de casca de arrozZea maysCasca-de-arroz carbonizadaCinza de bagaço de cana-de-açúcarTorta de filtro rotativo de cana-de-açúcarCarbonized rice husksBagasse ash from sugar caneFilter cake rotary sugarcaneCIENCIAS AGRARIASResíduos agroindustriais como fonte de silício para a cultura do milhoAgroindustrial subproducts as silicon source to corn cropinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesis-1-19af1cd22-8643-4a51-a4e4-186d385d1db0info:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFSCARinstname:Universidade Federal de São Carlos (UFSCAR)instacron:UFSCARORIGINAL5305.pdfapplication/pdf946081https://repositorio.ufscar.br/bitstream/ufscar/153/1/5305.pdf81e4f5bc1df570d2fc2c0af3a06d0f34MD51TEXT5305.pdf.txt5305.pdf.txtExtracted texttext/plain0https://repositorio.ufscar.br/bitstream/ufscar/153/4/5305.pdf.txtd41d8cd98f00b204e9800998ecf8427eMD54THUMBNAIL5305.pdf.jpg5305.pdf.jpgIM Thumbnailimage/jpeg10501https://repositorio.ufscar.br/bitstream/ufscar/153/5/5305.pdf.jpg0faff1ea0fa4455a9446e34e1a34aaffMD55ufscar/1532023-09-18 18:30:36.035oai:repositorio.ufscar.br:ufscar/153Repositório InstitucionalPUBhttps://repositorio.ufscar.br/oai/requestopendoar:43222023-09-18T18:30:36Repositório Institucional da UFSCAR - Universidade Federal de São Carlos (UFSCAR)false |
