Effect of Vigortem® on sweet potato clone INIVIT B-2000 (Ipomoea batatas (L.) Lam.) under dryland conditions

Abstract

The work was carried out in the municipality of "El Salvador", Guantánamo province, from March to June 2024, on a soft sialitic brown soil with carbonates. The objective was to evaluate different doses of Vigortem® on the sweet potato clone INIVIT B-2000 under dryland conditions. Four treatments were used, replicated five times each. The experimental design was randomized blocks. Stem length, number of leaves, number of tubers, tuber weight, and yield were evaluated. An analysis of variance (ANOVA) was performed on the obtained data, and differences between treatments were determined using Duncan's multiple range test (p<0.05) with the STATGRAPHICS PLUS version 5.1 statistical package. Among the evaluated doses, treatment 4 (5 L. ha⁻¹ of Vigortem®) obtained the best values, generating profits of $28,809.61.
