Abstract:

The culture of the bean (Phaseolus vulgaris L.) constitutes one of the most important issue in Brazil and much of Latin America, since it is considered the main source of protein in the social layers of smaller purchasing power. This study aims to evaluate the agronomic and physiological quality of bean seeds produced in organic cropping system in the city of Diamante D’Oeste. The genetic material for this work consists of six bean cultivars: Iapar 81, Iapar 31, Juriti IPR, IPR Graúna, IPR Uirapuru and Preto 60 dias. It was used random blocks design with four replications. The experimental plot consisted of six rows spaced 0.50 m and 5 m in length, which we evaluated the four central rows but 0.5 m start and end of each row. The following parameters were evaluated: The plant height, number of nodes on the main stem, total number of mature pods, average number of seeds per mature pods, length of pods, productivity, thousand grain weight, examination of infested seeds, germination, first count of germination test, accelerated aging test and electrical conductivity test. The cultivar IPR Graúna had the best averages for number of pods per plant, pod length and number of seeds per pod. In accelerated aging tests, germination and first count of germination test, stood out with the best averages, the cultivars Iapar 31 and IPR Graúna. Considering only the productivity, it can be recommend any of the studied cultivars organic for cropping in Diamante D’Oeste. Among the characteristics correlated with productivity, only the level of infestation seeds showed significant correlations.
