Resumo: | Sesame is considered the oldest oilseed in use by mankind. It is a culture of high complexity Morphophysiological with great variability in growth habit. Knowledge about factors involved in the growth and nutrition of plants allows producers proper planning of culture, contributing to a more efficient use of production area aiming to increase productivity becoming the study of the growth and accumulation of nutrients in the ground sesame seeds, but they are still few studies in the Northeast with culture. The purpose of the research was to evaluate the growth and accumulation of nutrients in sesame cultivars during their development. Two experiments were performed in Horta Didactics at UFERSA Mossoro-RN, from November 2014 to February 2015 and from April to July 2015. The experimental delineation in each experiment was a randomized complete block design with four replications. The treatments were arranged in a split plot where each experimental plot was represented by sesame cultivars: CNPA G2, CNPA G3 and CNPA G4 and the subplots consisted of the collection times, the first being conducted 21 days after sowing and the following at intervals of 14 days (35, 49, 63, 77, 91 and 105 DAS). The growth analysis characteristics evaluated were: plant height, stem diameter, leaf area, dry matter accumulation in leaves, stems, fruits and plant, leaf area index, duration of leaf area, leaf area ratio, rate absolute growth, growth rate cultivation, thousand seed weight, number of fruits per plant and grain yield. In relation to the accumulation of chemical analysis were: nitrogen, phosphorus and potassium. The homogeneity of the variances was made for all variables, except for dry weight of the leaf, making it possible to carry out a joint analysis of the experiments. Independent of the cultivation period, sesame plants presented slow growth until 35 DAS, and for the time I growth intensified up to 91 DAS and for the time II until 77 DAS, where the CNPA G4 revealed higher response regarding the cultivars in two harvest time. The total accumulation of nutrients to the cycle of the final followed the decreasing order of N> K> P in the two growing seasons, where period of increased demand for nutrients occurred between 77 and 105 DAS. In relation to the cultivars, the CNPA G3 had higher accumulations at the time I, while the CNPA G4 at the time II |

É uma cultura de elevada complexidade morfofisiológica, com grande variabilidade no hábito de crescimento. O conhecimento sobre os fatores envolvidos no crescimento e nutrição de plantas permite aos produtores o planejamento adequado da cultura, contribuindo para uma maior eficiência na utilização da área de produção visando à maior produtividade, tornando-se o estudo do crescimento e acúmulo de nutrientes no gergelim fundamental, porém ainda são escassos os estudos na região Nordeste com a cultura. O objetivo da pesquisa foi avaliar o crescimento e o acúmulo de nutrientes em cultivares de gergelim durante seu desenvolvimento. Dois experimentos foram conduzidos na Horta Didática da UFERSA em Mossoró-RN, no período de novembro de 2014 a fevereiro de 2015 e de abril a julho de 2015. O delineamento experimental em cada experimento foi em blocos casualizados completos, com quatro repetições. Os tratamentos foram dispostos em parcelas subdivididas, onde as parcelas foram representadas pelas cultivares de gergelim: CNPA G2, CNPA G3 e CNPA G4 e as subparcelas consistiram das épocas de coletas, sendo a primeira realizada 21 dias após a semeadura e as seguintes em intervalos de 14 dias (35, 49, 63, 77, 91 e 105 DAS). As características de análise de crescimento avaliadas foram: altura média de plantas, diâmetro caulinar, área foliar, acúmulo de massa seca nas folhas, caule, frutos e planta, índice de área foliar, duração da área foliar, razão da área foliar, taxa de crescimento absoluto, taxa de crescimento de cultivo, peso de mil sementes, número de frutos por planta e rendimento de grãos. Com relação às análises químicas de acúmulo foram: nitrogênio, fósforo e potássio. A homogeneidade das variâncias foi aceita para todas as variáveis, exceto para massa seca da folha, possibilitando a realização de uma análise conjunta dos experimentos. Independentes da época de cultivo, as plantas de gergelim apresentaram crescimento lento até os 35 DAS, sendo que para a época I o crescimento intensificou-se até 91 DAS e para a época II até 77 DAS, onde a cultivar CNPA G4 mostrou resposta superior em relação às cultivares estudadas nas duas épocas de cultivo. O acúmulo total de nutrientes ao final do ciclo obedeceu a ordem decrescente de N > K > P nas duas épocas de cultivo, onde período de maior demanda de nutrientes ocorreu entre 77 e 105 DAS. Em relação as cultivares, a CNPA G3 obteve maiores acúmulos na época I, enquanto que a CNPA G4 na época IICoordenação de Aperfeiçoamento de Pessoal de Nível SuperiorUniversidade Federal Rural do Semi-ÁridoBrasilUFERSAPrograma de Pós-Graduação em FitotecniaSilveira, Lindomar Maria da88207340444http://lattes.cnpq.br/2988333573887017Barros Júnior, Aurélio Paes02835623400http://lattes.cnpq.br/783468674101327103853222323http://lattes.cnpq.br/4618854331888919Grangeiro, Leilson Costa02108750460http://lattes.cnpq.br/1788174638876714Silveira, Lindomar Maria da88207340444http://lattes.cnpq.br/2988333573887017Ribeiro, Rayanne Maria Paula2017-03-21T15:05:08Z2016-02-26info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfapplication/pdfRIBEIRO, Rayanne Maria Paula.
