In the department of Nariño, the area cultivated in cereals has no rotation alternatives that allow farmers to improve their incomes, in addition to breaking pathogen cycles and diversifying their production systems. A possible option could be shrub pea. In SENA's Lope Farm sectional Nariño, the effect of sowing season and training systems on five genotypes of shrub pea was evaluated. The sowing season corresponded to march (season I), april (season II) and may (season III). A randomized complete block design was used in each period in divided plots. The main plot corresponded to vertical training system (TV), horizontal training system (TH) and any training system (ST), and the subplots to five genotypes of shrub pea. The variables evaluated were: days at flowering, days at harvest in green, pod weight, number of pods per plant, yield and percentage of healthy pods. The viability of the treatments was determined using the partial budget analysis. The results indicated higher yields in seasons II and III. The TV and TH systems exceeded the ST in percentage of healthy pods (%VS). Lines UN6651 and UN5174 stood out in pod green weight and yield. UN6651 got the best response for % VS. The greatest economic viability at seasons I and III was for the any training system and at season II for the systems vertical training and horizontal training.
