The correct sampling of seeds during beneficiation is essential for them to adequately represent the entire population of the lot from which they were extracted. The sampling procedure can be performed manually, with insertion nozzles or by automatic methods, depending on the legislation, the species and the available structure. The objective of the work was to evaluate different methodologies for sampling soybean seeds, during the packaging process and their influence on their physical and physiological qualities, prior to their storage. The experiment was carried out at the Seed Processing Unit of the Cooperativa Agropecuária Tradição, in Pato Branco / PR, in 2019. The design was completely randomized, with four replications. The sampling methods tested were: continuous automatic; with flow interruption; with 180X4.0 cm nozzle and; with 120X2.5 cm nozzle, applied during the seed packing process. After the collections, the seeds were submitted to physical and physiological quality analyzes at the UTFPR Didactic Seed Analysis Laboratory, Câmpus Dois Vizinhos. The data were subjected to analysis of variance and compared by Tukey, at 5% probability. The sampling methods tested did not interfere with the results of the physiological quality attributes for soybean seeds. The double-type nozzles affected the results of physical purity of the sampled lots, due to the breaking of the seeds at the time of simple collection. The percentage of broken seeds did not disqualify the lots in accordance with current legislation. |
