Caramel INIAP-382). For its development, a Completely Random Block Design (DBCA) was used with five treatments and four repetitions, with a total of 20 experimental units. The treatments were the following: Control; T1 (3 Tn/ha Nutrisano+100 l/ha NutriBiol); T2 (6 Tn/ha Nutrisano+150 l/ha NutriBiol); T3 (9 Tn/ha Nutrisano+200 l/ha NutriBiol) and T4 (12 Tn/ha Nutrisano+250 l/ha NutriBiol); the variables to be evaluated consisted of phenology, growth variables, and yield. For the statistical analysis of data, the InfoStat software was used using analysis of variance (ANOVA), for the statistical differences a 95% Tukey test was used, a 95% Pearson correlation and in turn the benefit ratio was calculated. -cost. The variables that presented significant statistical differences were: emergence (92.80%), plant height (45.66 cm), root length (21.15 cm), aerial dry biomass (326.33 g), dry biomass root (19.45 g), number of pods per plant (27.75), number of seeds per pod (2.68), pod length (2.99 cm) with T4 treatment; stem diameter (7.08 mm), number of branches (10.85), weight of 100 pods with seeds (195.04 g), weight of 100 seeds (76.19 g), pod diameter (1.72 cm), seed length (1.69 cm), seed diameter (1.10 cm) and yield (2.23 Tn/ha) with the T3 treatment. Regarding the benefit-cost analysis, the Control treatment obtained a value of 1.09, proving to be profitable, while the other treatments presented values ​​less than 1.

The treatments were the following: Control; T1 (3 Tn/ha Nutrisano+100 l/ha NutriBiol); T2 (6 Tn/ha Nutrisano+150 l/ha NutriBiol); T3 (9 Tn/ha Nutrisano+200 l/ha NutriBiol) y T4 (12 Tn/ha Nutrisano+250 l/ha NutriBiol); The variables to be evaluated consisted of phenology, growth variables and yield. For statistical data analysis, InfoStat software was used applying of variance (ANOVA), a Tukey test at 95%, a Pearson correlation at 95%, was used for statistical differences and in turn, the benefit-cost was calculated. The variables presented statistically significant differences were: emergence (92.80%), plant height (45.66 cm), root length (21.15 cm), aerial dry biomass (326.33 g), root dry biomass (19.45 g), number of pods per plant (27.75), number of seeds per pod (2,68), pod length (2,99 cm) with T4 treatment; stem diameter (7.08 mm), number of branches (10.85), weight of 100 pods with seeds (195.04 g), weight of 100 seeds (76.19 g), pod diameter (1.72 cm), seed length (1.69 cm), seed diameter (1.10 cm) and yield (2.23 Tn/ha) with T3 treatment. Regarding the benefit-cost analysis, the Control treatment obtained a value of 1.09 and as a result to be profitable, while the other treatments presented values were lower than 1.
