Autores: Hauth,Michele R.; Botelho,Fernando M.; Hoscher,Renata H.; Botelho,Sílvia de C. C.; Oliveira,Gabriel H. H. de.
ABSTRACT The knowledge of physical properties of grains is important for the optimization of postharvest operations. Thus, this study aimed to evaluate the effect of moisture content over physical properties of different cultivars of soybean. Soybean of cultivars NS7901RR, TMG1180RR, P98Y70 and TMG132RR were used, with initial moisture content of 0.32, 0.27, 0.25 and 0.21 dry basis (d.b.), respectively. In order to dry the samples, an oven of forced air circulation was used. Samples were dried at temperature of 50 °C, being the drying procedure stopped when the moisture content of soybean was equal or inferior than 0.15 (d.b.). During drying, for interested moisture contents, physical properties were determined: bulk density, equivalent diameter,...

Autores: Smaniotto,Thaís A. de S.; Resende,Osvaldo; Marçal,Kaique A. F.; Oliveira,Daniel E. C. de; Simon,Gustavo A.
Propôs-se, neste trabalho, avaliar a qualidade fisiológica das sementes de soja ao longo do armazenamento durante 180 dias em diferentes teores de água e em duas condições de temperatura. Foram utilizadas sementes de soja, cultivar CD 242 RR com teores de água iniciais de 12, 13 e 14% (b.u.). As sementes foram adquiridas com o teor de água de 11,0% (b.u.); em seguida, foram umedecidas em câmara BOD a 20 ºC e 85% de umidade relativa, homogeneizadas e acondicionadas em sacos plásticos de polipropileno; as embalagens foram mantidas em dois ambientes distintos. Com vista à avaliação das sementes ao longo do armazenamento foram realizadas as análises de teor de água, germinação, primeira contagem da germinação, índice de velocidade de germinação e condutividade...

Provedor de dados: 91
Autores: Coradi,Paulo C.; Lemes,Ângelo F. C.
ABSTRACT This study aimed to verify the capacity of silo-dryer-aerator prototype equipment operating as a silo-storage-aerator for soybean quality analysis. Soybeans with water content of 17% (wet basis – w.b.) were dried and stored in a silo-dryer-aerator system that was designed using a drying chamber, four independent storage cells, and a static capacity of 164 kg. Another batch of grains was stored in a silo-storage-aerator with a capacity of 1,200 kg. The experiment was set up in a completely randomized factorial 5 × 4 experimental design including five grain batches stored after being dried at 30, 40, and 50 °C (mixed grains were dried at three temperatures) in the silo-dryer-aerator cells and one mixed grain batch stored in the silo-storage-aerator...

Provedor de dados: 91
Autores: Baron,Felipe A.; Corassa Junior,Geomar M.; Fioresi,Dejales; Santi,Antônio L.; Martini,Renan T.; Kulczynski,Stela M.
ABSTRACT Yield potential of agricultural fields associated with plant spatial arrangement could determine the physiological quality of soybean (Glycine max L.) seeds. Thus, this study aimed to evaluate the physiological quality of soybean seeds from different yield environments and plant densities. Experiments were carried out in Boa Vista das Missões-RS, Brazil, during the 2014/2015 growing season. Yield environments were delineated by overlapping yield maps from the 2008, 2009/2010 and 2011/2012 growing seasons. The experimental design was a randomized complete block in a 2 x 5 factorial arrangement with two yield environments (low and high) and five plant densities, with four replicates. Two varieties were tested: Brasmax Ativa RR (10, 15, 20, 25 and 30...

Spatial arrangements and fertilizer doses on soybean yield and its components
Provedor de dados: 91
Autores: Duarte,Tiago C.; Cruz,Simério C. S.; Soares,Guilherme F.; Sena Júnior,Darly G. de; Machado,Carla G.
ABSTRACT The aim with this study was to evaluate the effects of single- and twin-row spatial arrangements associated with different doses of fertilization on soybean yield and its components. The experiment was carried out at Federal University of Goiás, Campus of Jataí, in a split-plot randomized block design with 10 treatments and four replicates. Each plot corresponded to a dose of P and K fertilization (0, 50, 100, 200 and 400% of the recommended dose) and the subplots to two types of spatial arrangements: single and twin rows. The yield components evaluated were plant final population, number of pods and seeds per plant, number of seeds per pod, weight of a thousand grains and yield. The increase in fertilization dose, even at doses two and four times...

Provedor de dados: 124
Autores: Silva,Hernani Alves da; Moraes,Anibal de; Carvalho,Paulo César de Faccio; Fonseca,Adriel Ferreira da; Dias,Carlos Tadeu dos Santos.
The adoption of no-till system (NTS) combined with crop-livestock integration (CLI) has been a strategy promoted in Brazil, aiming to maximize areas yield and increase agribusiness profitability. This study aimed to evaluate grains yield and phytotechnical attributes from maize and soybean culture by CLI system under NTS after winter annual pure and diversified pastures with the absence or presence of grazing animals. The experiment was installed in Castro (Paraná State, Brazil) on in a dystrophic Humic Rhodic Hapludox with a clay texture, using experimental design of randomized complete blocks in 4 x 2 factorial scheme with three replications. Treatments included four pasture combinations (diversified or pure) and animal categories (light and heavy)...

Gray scale of radiographic images in the assessment of degree moisture in soybean seeds
Provedor de dados: 109
Autores: Trujillo,Heiber Andrés; Guilhien Gomes-Junior,Francisco; Rondinel-Mendoza,Natalie Verónika; Trujillo,Carlos Humberto.
Abstract The moisture degree is one of the most important factors in choosing procedures for obtaining high quality seeds. In most quality control programs, the degree of moisture is determined by laboratory tests, based on the maximum removal of water when the seed is subjected to the application of heat under controlled conditions. The radiographic image is characterized by the generation of images with different levels of gray after the interaction of X-rays with the seed tissues. The objective of this research was to determine the gray scale values of radiographic images of soybean (Glycine max (L.)) seeds with different levels of hydration, aiming to establish relationships with the conventional method of moisture determination. Radiographic images of...
