Bean (Phaseolus vulgaris L.) is a crop of great importance in the country and in the state of Paraná, being a source of income for small farmers. However, it presents a high cost of production, from the acquisition of seeds and the handling of the crop, which is very sensitive. With this, many producers in an attempt to reduce the cost of production with the purchase of certified seeds end up opting to reserve part of the grain crop to be used as seeds in the next harvest. But they do not take into account that the biggest losers are themselves, without knowing what the real performance of the seeds will be in establishing them in the field, where they can end up losing in productivity. Thus the objective of this work was to evaluate the physical and physiological quality of bean seeds saved by rural and commercial producers produced in the southwestern region of Paraná, in order to characterize the adoption of this practice regarding its technical viability. Four lots of seeds of the cultivars ANfc 9 and IPR Tangará were collected, being two lots from companies owning RENASEM and two lots of seeds saved, acquired with farmers who saved part of their grain production to implant the next harvest of bean. After the seeds were collected, seeds were taken to UTFPR seed laboratory, Campus Pato Branco / PR, where the following tests were carried out to evaluate the physical and physiological quality of the seeds: weight of one thousand seeds, germination test and accelerated aging. Data were submitted to analysis of variance and compared by Tukey's test, at 5% probability. The physical and physiological quality presented a distinct quality standard between lots of saved and commercial seeds. All commercial lots met the quality standards required by the legislation. However, the seed lots saved for both cultivars were below that required by the legislation. With this, the grain yield will be influenced by the origin of the lots and the quality of the seeds. |
