| Disgrifiad: | Introduction. The use of biostimulants has emerged as a promising strategy to enhance common bean productivity. Objective. To evaluate the effect of different chemical fertilization levels combined with foliar application of VIUSID® Agro on the morpho-productive variables of bean, as well as analyze their relationships through a multivariate approach. Materials and methods. Between December 2021 and March 2022, in Sancti Spíritus, Cuba, an experiment was conducted using a randomized complete block design with a 3 × 2 factorial arrangement and five replications. Three levels of chemical fertilization (Fq1 = 50 %, Fq2 = 75 %, and Fq3 = 100 % of the recommended rate) were combined with two doses of VIUSID® Agro (V1 = 0.25 and V2 = 0.50 L ha⁻1) to evaluate the morpho-productive variables of the crop. Data were analyzed using two-way analysis of variance, Pearson correlation analysis, and principal component analysis. Results. The application of V₂, compared with V₁, increased plant height by 14, 11, and 7 %, leaf area by 22, 15, and 11 %, fresh biomass by 17, 15, and 18 %, and dry biomass by 12, 13, and 18 % under Fq₃, Fq₂, and Fq₁, respectively. In contrast, V₁ outperformed V₂ in reproductive performance, increasing the number of pods by 32, 25, and 15 %, seed mass by 13, 8, and 10 %, and grain yield by 17, 15, and 18 % under Fq₃, Fq₂, and Fq₁, respectively. Yield was positively correlated with seed mass (r = 1.00) and number of pods (r = 0.74), while the first two principal components explained more than 70 % of the total variability, indicating an integrated response of the production system. Conclusions. The application of VIUSID® Agro decreased fertilization by 25 % and increased bean productivity. |
