| ABSTRACT: The use of larger seeds may improve the initial development, plant stand, and mass productivity in forage crops. The present study aimed to evaluate the effect of the size of seeds of Sudan grass (Sorghum sudanense L.), standardized on density, on parameters of physiological quality and crop productivity. Seeds were processed in a gravitational table in order to become uniform in terms of density and then submitted to sieves with apertures of 1.75 or 2.00 mm. Three different treatments (seeds without size classification, seeds with diameter between 1.75 mm and 1.99 mm, and seeds with diameter above 2.00 mm) were compared. This study consisted of a laboratory stage for the analysis of physiological variables of seed, and a stage in field plots... |

| ABSTRACT Currently, the domestic agricultural sector has become increasingly professionalized; therefore, measures aimed at safety in the workplace and monitoring of environmental risks have been gaining major importance in this scenario. Thus, this study aimed at assessing internal environmental conditions of four soybean processing plants (SPPs) operating with a screen-air machine, densimetric table and with or without spiral separator. These plants are in the state of Rio Grande do Sul (Brazil), being assessed on site considering every feature related to machinery and equipment, as well as technological level. Field evaluations comprised measurements of noise, illuminance and suspended dust. Results showed that none of the SPPs is in full accordance... |

| ABSTRACT This study aimed to evaluate the quality of soybean seeds with high level of mechanical damages from different processing stages and stored with and without fungicide treatment. Collections of seed samples were performed during the processing at the following points: hopper, pre-cleaning, dryer, cleaning, spiral, sieve-classifier and the gravity table. The experimental design was completely randomized in a 9 x 2 factorial scheme, with 9 collection points and two seed treatments, in four replicates. The seeds were then evaluated immediately after processing and after six months of storage. The processing progressively improved the attributes of soybean seed quality throughout the different stages in which the gravity table plays an important role... |
