Interfer?ncia de Bidens pilosa no crescimento e fisiologia do cafeeiro (Coffea arabica L.) submetido a aduba??es fosfatadas. 2019. 62 p. Disserta??o (Mestrado em Produ??o Vegetal) ? Programa de P?s-Gradua??o em Produ??o Vegetal, Universidade Federal dos Vales do Jequitinhonha e Mucuri, Diamantina, 2019.http://acervo.ufvjm.edu.br/jspui/handle/1/2381?rea de concentra??o: Produ??o Vegetal.A fase inicial de crescimento do cafeeiro (Coffea arabica L.) ? considerada uma das mais sens?veis ? interfer?ncia das plantas daninhas. Condi??es de estresse e defici?ncia nutricional podem possibilitar maior aproveitamento de recursos e crescimento das plantas daninhas em compara??o as plantas de caf?, devido a sua rusticidade, sendo assim, fatores que busquem maior vantagem para o cafeeiro como a disponibiliza??o lenta e eficiente dos fertilizantes pode beneficiar seu crescimento diante da competi??o. Objetivou-se avaliar a interfer?ncia de Bidens pilosa no crescimento e fisiologia do cafeeiro submetido a diferentes formas de libera??o das aduba??es fosfatadas. O experimento foi conduzido em casa de vegeta??o da UFVJM no delineamento em blocos casualizados dispostos em esquema fatorial 4 x 6, com quatro repeti??es. Foram utilizadas mudas de caf? cultivar Rubi MG 1192 em competi??o com quatro n?veis de infesta??o (nulo?cafeeiro livre da competi??o, baixo?uma planta/vaso, m?dio?duas plantas/vaso e alto?quatro plantas/vaso), combinadas com fontes de P2O5 (Super Simples, MAP Convencional, Organomineral Farelado, Organomineral Peletizado, MAP Revestido com pol?mero e tratamento Controle sem aduba??o) em doses de 100% equivalente a aduba??o mineral de f?sforo para o plantio do cafeeiro. Realizou-se a semeadura de B. pilosa aos 30 dias ap?s o transplantio do caf?, convivendo no mesmo vaso por 90 dias. As plantas de caf? sob competi??o com B. pilosa, reduziram o crescimento e teor de f?sforo foliar, sendo essa redu??o intensificada com o aumento da densidade da competi??o. Para a fisiologia das plantas de caf?, a fluoresc?ncia da clorofila e os teores de clorofila a e b foram influenciados, com preju?zos no aparelho fotossint?tico do cafeeiro. As fontes de fertilizantes com a tecnologia Organomineral Farelado, Organomineral Peletizado e MAP revestido com pol?mero proporcionaram maior aproveitamento do nutriente das plantas de caf?, por promoverem libera??o lenta, com menor competi??o da B. pilosa.Submitted by Jos?

Pesquisa do Estado de Minas Gerais (FAPEMIG)Disserta??o (Mestrado) ? Programa de P?s-Gradua??o em Produ??o Vegetal, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2019.The early growth phase of coffee (Coffea arabica L.) is considered one of the most sensitive to weed interference. Conditions of stress and nutritional deficiency may enable greater resource utilization and weed growth compared to coffee plants, due to their rusticity, thus, factors that seek greater advantage for coffee as the slow and efficient availability of fertilizers can benefit. Its growth in the face of competition. The objective of this study was to evaluate the interference of Bidens pilosa on the growth and physiology of coffee submitted to different forms of phosphate fertilizer release. The experiment was conducted in a UFVJM greenhouse in a randomized block design arranged in a 4 x 6 factorial scheme with four replications. Rubi MG 1192 coffee seedlings were used in competition with four levels of infestation (null ? free competition coffee, low ? one plant / pot, medium ? two plants / pot and high ? four plants / pot), combined with seedlings. P2O5 (Super Simple, Conventional MAP, Bran Organomineral, Pelleted Organomineral, Polymer Coated MAP and Control Treatment without Fertilization) at doses of 100% equivalent to phosphorus mineral fertilization for coffee planting. B. pilosa was sown at 30 days after coffee transplantation, living in the same pot for 90 days. Coffee plants under competition with B. pilosa reduced growth and leaf phosphorus content, which was intensified with increasing competition density. For the physiology of coffee plants, the chlorophyll fluorescence and chlorophyll a and b contents were influenced, with damage to the coffee photosynthetic apparatus. Fertilizer sources with Bran Organomineral, Pelleted Organomineral and polymer-coated MAP technology provided better utilization of coffee plant nutrients by promoting slow release, with less competition from B. pilosa.porUFVJMA concess?o da licen?a deste item refere-se ao ? termo de autoriza??o impresso assinado pelo autor, assim como na licen?a Creative Commons, com as seguintes condi??es: Na qualidade de titular dos direitos de autor da publica??o, autorizo a Universidade Federal dos Vales do Jequitinhonha e Mucuri e o IBICT a disponibilizar por meio de seus reposit?rios, sem ressarcimento dos direitos autorais, de acordo com a Lei n? 9610/98, o texto integral da obra disponibilizada, conforme permiss?es assinaladas, para fins de leitura, impress?o e/ou download, a t?tulo de divulga??o da produ??o cient?fica brasileira, e preserva??o, a partir desta data.info:eu-repo/semantics/openAccessInterfer?ncia de Bidens pilosa no crescimento e fisiologia do cafeeiro (Coffea arabica L.) submetido a aduba??es fosfatadasInterference of Bidens pilosa on growth and physiology of coffee (Coffea arabica L.) subjected to phosphate fertilizersinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisCaf?Competi??oF?sforoLibera??o lentaCoffeeCompetitionPhosphorLenta releasereponame:Repositório Institucional da UFVJMinstname:Universidade Federal dos Vales do Jequitinhonha e Mucuri (UFVJM)instacron:UFVJMTEXTcaroline_maira_miranda_machado.pdf.txtcaroline_maira_miranda_machado.pdf.txtExtracted texttext/plain136579http://acervo.ufvjm.edu.br/jspui/bitstream/1/2381/6/caroline_maira_miranda_machado.pdf.txt68d31787255128a158d8a6e5dcb16eb3MD56LICENSElicense.txtlicense.txttext/plain;
