Resumo: | ABSTRACT The objective of this study was to evaluate the performance of the common bean crop grown with application of osmoprotectants based on algae of the genus Durvillaea potatorum in the winter crop season, with occurrence or not of water suppression. The experiment used a randomized block design, in split plots, arranged in a 4x7 factorial scheme, in which the plots were composed of four treatments - periods of water suppression (7, 14, 21 days and the control treatment: 100% of field capacity throughout the crop cycle) and the subplots consisted of seven types of osmoprotectants. The treatments with osmoprotectants was applied during the full flowering of the common bean. Three days after application of osmoprotectants, the treatments with suppression of irrigation were established. The use of osmoprotectants based on algae of the genus Durvillaea does not affect the variables plant height, stem diameter, stem and pod dry matter, first pod height, number of pods per plant and number of grains per pod in common bean plants cultivated with occurrence of water suppression. Common bean plants under water restriction conditions have lower leaf and shoot dry matter and lower 100-grain weight. Common bean grain yield was influenced by the type of osmoprotectants and the water suppression period.
