Background: The aguaymanto has aroused great interest in both the national and international markets for its different uses: aesthetic, medicinal, nutritional and gastronomic. However, agronomic management strategies for this crop with commercial potential are unknown, resulting in low yields and profitability. Objective: To evaluate the effect of different doses of Biogen 1 biostimulant (Bg) and planting distances (PD) on the production and economic analysis of aguaymanto. Methodology: Two factors were evaluated: planting density and dose of biostimulant, resulting in 6 treatments: T1- control (250 ml Bg/200 L + 1m x 1m); T2 (250 ml Bg/200 L + 1.5m x1.5m); T3 (500 ml Bg/200 L + 1m x 1m); T4 (500 ml Bg/200 L + 1.5m x 1.5m); T5 (750 ml Bg/200 L + 1m x 1m) and T6 (750 ml Bg/ 200 L + 1.5m x 1.5m), using a randomized complete block design. The following production parameters were evaluated: number of fruits per plant-NFP, fruit weight-FW (g), fruit diameter-FD (cm), yield per plant-YPP (kg/plant), yield per hectare-YPHA (kg ha-1). Results: T6 had the best yields per plant; however, in the yield per hectare and in the economic analysis, T5 performed better. The correlation in NFP was positive on FD, YPP and YPHA; also, FW with respect to FD and YPP. FD was positively correlated with YPP. However, YPP presented a very weak correlation with YPHA. Implications: Proper use of biostimulants and planting distance increases crop yields. Conclusion: The T6 treatment improved the parameters evaluated per plant, and T5 improved YPHA and the B/C ratio. This positive correlation indicates the directly proportional effect between the parameters
