The sowing of seeds during different seasons, characterized by distinct environmental conditions, can result in different agronomic characteristics and production rates of agricultural crops. Considering the lack of information on the effect of climatic variations on the agronomic performance of snap bean (Phaseolus vulgaris), it is important to evaluate the productivity and nutrient content when sown at different times of the year. Thus, the study aimed to evaluated plant productivity, and seed mineral and phenolic compound composition in different genotypes and cultivars of bush snap bean UEL 1, UEL 2, Isla Macarrão Baixo, Isla Manteiga Baixo, and Feltrin Macarrão Napoli sowed in the spring and autumn. The number of pods per plant, seeds per pod, seeds per plant, and seed yield were evaluated. Chemical composition of the seeds was determined by measuring the amounts of crude protein, calcium, magnesium, potassium, phosphorus, sulfur, iron, zinc, manganese, and total phenolic compounds present. The joint analysis of variance of the experiments was performed, with means compared by the Tukey test, at 5%. The interaction between genotype and sowing season affects the number of seeds per plant, seed productivity, and the seed concentrations of crude protein, zinc, and manganese. Spring sowing favored seed yield in the Isla Manteiga Baixo cultivar, the number of pods per plant, and the accumulation of phosphorus and iron in the seeds. Autumn sowing resulted in an increase in the seed-concentrations of potassium and total phenolic compounds. Seed-concentrations of calcium and manganese varied by genotype.
