The bean crop (Phaseolus vulgaris L.) has great importance in Brazil as it is a significant source of protein for the population. In Parana this crop has also great importance and the State always ranks among the largest producers in the country. This study aimed to evaluate in different trials the growth and yield of black bean cultivars. Experiments were performed in three trials, with six cultivars in four blocks, totaling 24 plots per trial on a split-plot design where the trial was the mainplot and cultivars was the subplots. It was collected yield and growth data at four growth stages, and also climatic data. There was interaction between trial and cultivar for yield and all yield components analyzed, as well as with a high number of morphological parameters evaluated. In general, the highest yield was observed in the first trial, reducing in the second trial and decreasing even more in the third trial, and the cultivars BRS Esplendor and IPR Uirapuru were in the cultivars group with highest yield at all three trials. The yield component grain number per area, and the growth data harvest index, were the parameters with highest correlation with yield. The climatic data that had most influence on yield were the temperature and radiation, and the rain was negatively correlated with yield. With the results obtained in this study it was found that the cultivars developed with different speed and strength, changing the yield according to the trial, but the cultivars BRS Esplendor and IPR Uirapuru were the most stable and with higher yield, being the most recommended cultivars for seeding in the region of Guarapuava.
