Intraspecific competition of hybrids using mixtures of pollinator lines for hyb...
Rocha Eberhardt, Paulo Eduardo; Schuch, Luis Osmar Braga; Mondo, Vitor Vaz; Franco, Daniel Fernandez; Medeiros, Letícia Ramon de; Radke, Aline KlugThe aim of this study was to evaluate the use of pollinator seed mixture to obtain hybrid rice seeds. The study was performed at Embrapa Clima Temperado, in the harvests of 2015/2016 and 2016/2017. Seeds of hybrids H7 and BRS AH 703 CL and the pollinator, Puitá INTA-CL cultivar were used in the proportions of 0.00%, 0.75%, 1.50%, 3.00%, 6.00%, 12.00% and 24.00% in the first year and 0.00%, 0.75%, 1.50%, 3.00%, ...
Efeitos de regulador de crescimento, controle de doenças e densidade de semeadu...
Sofiatti, Valdinei; Schuch, Luis Osmar Braga; Pinto, Jonas Farias; Cargnin, Adeliano; Leitzke, Luciane Nolasko; Hölbig, Letícia Dos SantosO objetivo foi avaliar o efeito da aplicação do regulador de crescimento ethephon visando à uniformidade de floração e maturação e o controle de doenças de final de ciclo da cultura do arroz. Foi utilizado o fungicida tebuconazole e a avaliou-se a qualidade industrial de grãos das cultivares IRGA 417 e El Paso L 144, em duas densidades de semeadura. O experimento consistiu de uma combinação fatorial (2x2x4) de ...
Influence of seeds vigor in the attributes of soybean yield
Struker, Steven; Carvalho, Ivan Ricardo; Szareski, Vinícius Jardel; Barbosa, Maurício Horbach; Souza, Velci Queiroz de; Conte, Giordano GelainThis study aimed to evaluate the influence of three levels of seeds vigor in the attributes of soybean yield when cultivated in the state of Rio Grande do Sul. The experiment was conducted in the crop season of 2017/2018, in the city of Condor, located in the state of Rio Grande do Sul, Brazil. The experimental design was random blocks organized in factorial scheme being two soybean genotypes (NA 5909 RG and BM...
Anthracnose severity in common bacterial blight in bean under different spacing...
Schuch, Luis Osmar Braga; Antunes, Irajá Ferreira; Ludwig, Marcos Paulo; Oliveira, Sandro de; Lemes, Elisa SouzaThe beans (Phaseolus vulgaris L.) has great economic and social importance in Brazil as part of the basic food. The incidence of leaf diseases cause damage to crops. The objective was to evaluate the severity of Anthracnose and Bacterial blight common in bean under different spacing and plant populations. The experiments were conducted in the experimental area of Agricultural Center of Palma, the Federal Univer...
Morphophysiological performance of medium cycle soybean cultivars under flooding
Ludwig, Marcos Paulo; Oliveira, Sandro de; Schuch, Luis Osmar Braga; Vernetti Junior, Francisco Jesus; Seus, Rogério; Lemes, Elisa SouzaThe increase in soybean cultivation in Brazil has reached areas previously used for other purposes, such as in regions of lowland soils, thus being subject to possible soil flooding. This study aimed to evaluate morphophysiological changes in medium cycle soybean cultivars, under soil flooding conditions, in the vegetative and reproductive stages to recommend cultivars. The experiments were conducted at the Est...
Calidad fisiológica de semillas y variabilidad entre plantas en una población d...
Schuch, Luis Osmar Braga; Kohls, Igor; Almeida, Andreia da Silva; Deuner, Cristiane; Cavalcante, Jerffeson AraujoLa calidad fisiológica de la semilla podría afectar el rendimiento de granos de arroz. Las diferencias en la calidad fisiológica de las semillas pueden causar la reducción y desuniformidad de la emergencia en el campo, acarreando una diferencia en el crecimiento inicial de las plantas, y consecuentemente afectando el cultivo y su rendimiento. Se realizo un experimento con el objetivo de evaluar la distribución ...
