Grain yield and quality of common bean cultivars cultivated in the water and winter seasons
In Brazil, the common bean is growing in three seasons, with each one requiring different technological levels to obtain high yields. However, studies to evaluate the season effect on grain yield and quality in bean cultivars are scarce. The objective of this study was to evaluate the performance of common bean cultivars of the commercial group from ‘carioca’, regarding the agronomic and technological characteristics of the grains, cultivated in the waters and winter seasons, as well as indicate the best genotypes to be cultivated in each season. The experimental design was a randomized complete block design, with 20 treatments, with 10 cultivars of bean and 2 seasons, in three replications. The agronomic attributes were evaluated: number of pods per plant, number of grains per pod, mass of 100 grains and grain yield, and grain technological attributes, such as cooking time, hydration ratio and time to maximum hydration of the grains. The yield and hydration ratio of the bean cultivars were higher in the winter season. The winter season presented a longer time for the maximum hydration of the grains than waters season, however the time for cooking of the grains was not affected. In the experimental conditions, for the winter season it is recommended BRS MG Requinte cultivar and for the waters season BRS MG Horizonte cultivar. The BRS MG Talismã cultivar is recommended for crop cultivation in the two seasons.
