No. of bitstreams: 2 Dissertação - Eloene Rodrigues Godoy - 2016.pdf: 2017416 bytes, checksum: 606092ba846fd0631f779cc9e9fc7264 (MD5) license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5) Previous issue date: 2016-12-02 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES / This study aimed to evaluate the performance of six peanut lines and two cultivars based on production indicators, in an organic system of transition in the region of Jataí – GO. The experiment was conducted at Universidade Federal de Goiás - Campi Jataí, and implemented on November 30th, 2015. The experimental design has happened with randomized blocks (RBD) with eight treatments (2012-38, 2012-71; 2013-293, 2013-415; 2013-413 OL; 2013-415 OL), and with the commercial varieties Runner IAC 886 and IAC 505 in four replications. The characteristics evaluated are divided into two categories: (a) Productivity, measured by weighing the parcel; and (b) Weight of 100 pods; weight of seeds in 100 pods and the weight of 100 seed. After the sowing time, period of 88, 119 and 140 days, the weighing of fresh and dry matter of fruit, stem and roots have been made. During the cycle of the plants, there were photographic records for the growth and coverage factor analysis. The manual harvesting process of the crop, on April 28th, 2016 (corresponding to 140 days after sowing), happened when 60% to 70% of the pods presented brown color pigments inside. Through linear regression, it was possible to estimate the fruiting period by subtracting the days of maturity (harvest) from the fruiting ones. The evaluated strains differ statistically with a emphasis on the lineage 13-425OL productivity. Based on the parameters studied, the strains have the potential to be cultivated through the organic system. Fungal diseases caused significant losses on the coverage factor. / Nessa pesquisa objetivou-se avaliar o desempenho de seis linhagens de amendoim e duas cultivares, com base em indicadores produtivos, em sistema de transição orgânico na região de Jataí- GO. O experimento foi conduzido na Universidade Federal de Goiás - Regional Jataí, e implantado no dia 30 de novembro de 2015. O Delineamento experimental foi em Blocos Casualizados (DBC) com oito tratamentos (2012-38; 2012-71; 2013-293; 2013-415; 2013-413 OL; 2013- 415 OL), e com as variedades comerciais Runner IAC 886 e IAC 505 em quatro repetições. As características avaliadas se dividem em duas categorias: (a) Produtividade: avaliada através de pesagens do peso de vagens das parcelas, e (b) peso de 100 vagens, peso das sementes em 100 vagens e o peso de 100 sementes; Aos 88, 119 e 140 dias após a semeadura, foram feitas pesagens de matéria fresca e seca de frutos, assim como caules e raízes. Durante todo o ciclo das plantas, houve registros fotográficos para análise de crescimento e fator de cobertura. A colheita realizada, no dia 28 de abril de 2016 (correspondente a 150 dias após a semeadura), aconteceu quando 60% a 70% das vagens apresentavam pigmentos de cor marrom na parte interna. Por meio dos parâmetros de regressão, foi possível estimar o período de frutificação ao subtrair os dias de maturação (colheita) dos dias de frutificação. As linhagens avaliadas diferiram estatisticamente, com destaque maior de produtividade na linhagem 13-425OL. Com base nos parâmetros estudados, as linhagens apresentam potencial para serem cultivadas sob o sistema orgânico. As doenças fúngicas causaram perdas significativas no fator de cobertura.
