Resumo: Currently great emphasis is given for seed metering that assist rigorous demands in relation to longitudinal distribution of seeds, as well as to the index of fails in spacing laws, breaks and double seeds. The evaluation of these variable demands much time and work of attainment of data and processing. The objective of this work went propose to use of graphs of normal probability, facilitating the treatment of the data and decreasing the time of processing. The evaluation methodology consists in the counting of broken seeds, fail spacing and double seeds through the measure of the spacing among seeds, preliminary experiments through combinations of treatments had been carried through whose factors of variation were the level of the reservoir of seeds, the leveling of the seed metering, the speed of displacement and dosage of seeds. The evaluation was carried through in two parts, first through preliminary experiments for elaboration of the graphs of normal probability and later in experiments with bigger sampling for evaluation of the influence of the factors most important. It was done the evaluation of seed metering of rotating internal ring, and the amount of necessary data for the evaluation was very decreased through of the graphs of normal probability that facilitated to prioritize only the significant factors. The dosage of seeds was factor that more important because factor (D) have greater significance.

A avaliação destas variáveis demanda muito tempo e trabalho, tanto para obtenção de dados como para processamento. O objetivo deste trabalho foi propor a utilização de gráficos de probabilidade normal para facilitar o tratamento dos dados relativos aos fatores que possivelmente influem na qualidade de distribuição e diminuir o tempo de processamento dos dados de distribuição das sementes em semeadoras. A metodologia de avaliação constitui-se na medida dos espaçamentos entre sementes e contagem de sementes quebradas, espaçamentos falhos e sementes duplas. Foram realizados experimentos por meio de combinações de tratamentos cujos fatores de variação foram: o nível de sementes no reservatório, o nivelamento transversal da semeadora, a velocidade de deslocamento e a dosagem de sementes. Uma avaliação de semeadora provida de anel interno rotativo foi realizada em duas partes primeiramente com experimentos para construção dos gráficos de probabilidade normal e posteriormente em experimentos com maior amostragem de sementes para avaliação da influência dos fatores mais importantes detectados pelos gráficos de probabilidade normal. Verificou-se que a quantidade de dados necessários para a avaliação da semeadora é menor por meio da utilização dos gráficos de probabilidade normal, pois estes possibilitam priorizar os fatores significativos. A dosagem de sementes foi o fator que mais interferiu nas avaliações propostas, pois o fator (D) obteve maior significância.UEL2012-05-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionpesquisa empírica de campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/622210.5433/1679-0359.2012v33n2p507Semina: Ciências Agrárias; Vol. 33 No. 2 (2012); 507-518Semina: Ciências Agrárias; v. 33 n. 2 (2012); 507-5181679-03591676-546Xreponame:Semina.
