Resumen

Biostimulants are environmentally friendly products that improve plant metabolism and stimulate the plant by increasing its capacity to absorb nutrients from the soil. However, biostimulants present different responses in the plant. In order to evaluate the effect of the application of biostimulants on the yield of paprika bell pepper, a randomized complete block design with four treatments and four replications was applied. The treatments were: T1 (control without application), T2 (amino acids), T3 (humic acids) and T4 (Ascophyllum nodosum) at a dose of 1 L ha-1. Tukey’s test was used for the comparison of means. The results showed that Treatment 4 presented statistical significance (p < 0.10) with greater plant height (56.2 ± 0.42 cm), fruit length (19.2 ± 0.34 cm) and fruit diameter (3.48± 0.03 cm). Regarding the number of fruits per plant, the treatments T4, T2 and T3 obtained statistically similar means (22.5, 20.8 and 20.5 fruits, respectively), likewise, T4 presented higher fresh weight (601.42 ± 33.01 g plant-1), dry weight (143.19 ± 7.86 g plant-1) per plant and higher total yield (7.64 ± 0.42 t ha-1). It was concluded that the application of the biostimulant based on Ascophyllum nodosum extract at a dose of 1 L ha-1 had a greater significant effect on the yield of paprika bell pepper.
