Resumo: | This study aimed to evaluate the growth and development of soybean cultivars submitted in different spatial arrangements associated with weather temperature elements and solar radiation, and also the contribution of temperature elements, solar radiation, precipitation and the thermal time the duration of the development phases. The cultivars used were BMX Ativa RR, BMX Turbo RR e BMX Potência RR and the spatial arrangements were 45, crossed, 20, 20x40, 20x60 and 20x80 cm. Two field experiments were conducted in the experimental area of Agroclimatology Laboratory of the Federal University of Santa Maria, campus Frederico Westphalen/RS in the growing seasons of 2012/2013 and 2013/2014. During the crop cycle asked the following ratings: weekly count of the number of nodes; growth analysis; and monitoring of phenological scale. From these data, there was obtained plastochron, the conversion efficiency and regression models for the phenological stages. In the growing seasons 2012/2013 the plastochron cultivar BMX Turbo RR in spatial arrangement of 20 cm and the lowest BMX Potência RR, in the arrangement of 20x80 cm. In the growing seasons 2013/2014 the plastochron cultivar BMX Ativa RR in the cross arrangement and the lowest this cultivar in the arrangement of 20x40 cm. For all cultivars the only spatial arrangement which differed in both years, was to 20x40 cm which had lower plastochron values in the second year. The arrangement of 20x40 cm is favored by the approach of the internal lines of 20 cm, the best use of solar radiation by the rapid closure of these lines. The external lines of 40 cm favor the development, and facilitate the application of phytosanitary treatments. Higher conversion efficiencies of cultivars are obtained in paired arrangements. Paired arrangements and 20 cm, for having the highest leaf area index and possibly increased interception of diffuse radiation increase the conversion efficiency and productivity of the cultivars BMX Ativa RR and BMX Turbo RR. The thermal time in different phenological stages of soybean cultivars varies according to the growing seasons, and is determining the duration and follow-up phases. It is the factor that most influenced at all stages of development of cultivars, contributing over 95% in the regression models. Meteorological data associated with phenology identify the different weather conditions which culture is exposed and demonstrate the plasticity that this species has. |

As cultivares utilizadas foram BMX Ativa RR, BMX Turbo RR e BMX Potência RR e os arranjos espaciais de 45, cruzado, 20, 20x40, 20x60 e 20x80 cm. Conduziram-se dois experimentos a campo na área experimental do Laboratório de Agroclimatologia da Universidade Federal de Santa Maria campus Frederico Westphalen/RS nos anos agrícolas 2012/2013 e 2013/2014. Durante o cultivo foram feitas as seguintes avaliações: contagem semanal do número de nós, análise de crescimento semanal e acompanhamento da escala fenológica. A partir destas, obteve-se o plastocrono, a eficiência de conversão e os modelos de regressão para as fases fenológicas. No ano agrícola 2012/2013 o maior plastocrono foi da cultivar BMX Turbo RR no arranjo espacial de 20 cm e o menor na cultivar BMX Potência RR no arranjo de 20x80 cm. No ano agrícola 2013/2014 o maior plastocrono foi da cultivar BMX Ativa RR no arranjo cruzado e o menor nesta mesma cultivar, no arranjo de 20x40 cm. Para todas as cultivares o único arranjo espacial que diferiu nos dois anos, foi o de 20x40 cm onde obteve menores valores de plastocrono no segundo ano. O arranjo de 20x40 cm é favorecido pela aproximação das linhas internas de 20 cm, pelo melhor aproveitamento da radiação pelo rápido fechamento destas entrelinhas. As entrelinhas externas de 40 cm favorecem o desenvolvimento, além de facilitarem a aplicação dos tratamentos fitossanitários. Maiores eficiências de conversão das cultivares são obtidos nos arranjos pareados. Os arranjos pareados e 20 cm, por ter o maior índice de área foliar e possivelmente maior interceptação da radiação difusa aumentam a eficiência de conversão e a produtividade das cultivares BMX Ativa RR e BMX Turbo RR. A soma térmica acumulada nas diferentes fases fenológicas de cultivares de soja varia de acordo com o ano agrícola, e é determinante na duração e seguimento das fases. É o fator que mais influenciou em todas as fases de desenvolvimento das cultivares, contribuindo com mais de 95% nos modelos de regressão. Os dados meteorológicos associados a fenologia identificam as diferentes condições meteorológicas as quais a cultura é exposta e demostram a plasticidade que esta espécie apresenta.Coordenação de Aperfeiçoamento de Pessoal de Nível Superiorapplication/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em Agronomia - Agricultura e AmbienteUFSMBRAgronomiaGlycine maxTemperaturaSoma térmicaRadiação solarModelagem agrícolaTemperatureThermal sumSolar radiationAgricultural modelingCNPQ::CIENCIAS AGRARIAS::AGRONOMIAPlastocrono, eficiência de conversão e estimativa de duração das fases fenológicas na cultura da sojaPlastochron, conversion efficiency and duration of estimating the phases phenological in soybean cropinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisCaron, Braulio Otomarhttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4768041E3Sentelhas, Paulo Cesarhttp://lattes.cnpq.br/3064521898263661Paula, Gizelli Moiano dehttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4253599P7Cocco, Carinehttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4712359P8http://lattes.cnpq.br/0528539115922118Rockenbach, Ana Paula50010000000940030030030030030016170bb9-b076-4758-83e8-78cf6774f83b8e9bb201-8a48-4b40-b774-e3708aa36b0e69f69690-329c-4fa1-9414-e8d779c5a1efde16b133-2a2f-43cc-b974-fa5b9dd8ad3a62ebd310-04b8-4566-953a-8f1acdff2648info:eu-repo/semantics/openAccessreponame:Manancial - Repositório Digital da UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALROCKENBACH, ANA PAULA.pdfapplication/pdf1405234http://repositorio.ufsm.br/bitstream/1/4936/1/ROCKENBACH%2c%20ANA%20PAULA.pdff0e84305605de9fce802dd30e849fb0cMD51TEXTROCKENBACH, ANA PAULA.pdf.txtROCKENBACH, ANA PAULA.pdf.txtExtracted texttext/plain134332http://repositorio.ufsm.br/bitstream/1/4936/2/ROCKENBACH%2c%20ANA%20PAULA.pdf.txt3d0393d5a5c290cd1c283dc182dd6b99MD52THUMBNAILROCKENBACH, ANA PAULA.pdf.jpgROCKENBACH, ANA PAULA.pdf.jpgIM Thumbnailimage/jpeg4844http://repositorio.ufsm.br/bitstream/1/4936/3/ROCKENBACH%2c%20ANA%20PAULA.pdf.jpgbde70e592ce131e9d81a9f3bcaeb2627MD531/49362022-07-06 12:51:23.274oai:repositorio.ufsm.br:1/4936Repositório Institucionalhttp://repositorio.ufsm.br/PUBhttp://repositorio.ufsm.br/oai/requestopendoar:39132022-07-06T15:51:23Manancial - Repositório Digital da UFSM - Universidade Federal de Santa Maria (UFSM)false |
