Abstract

This study evaluated the effect of a bioactivator applied to seeds on the germination and early growth of INIAP 543-QPM corn seedlings. The experiment was conducted under controlled conditions in the plant science laboratory of the Manuel Félix López Higher Polytechnic School of Agriculture and Livestock in Manabí, located in Calceta, Manabí, Ecuador. A completely randomized design was used with three treatments: seeds pre-hydrated and treated with a bioactivator (T1), dry seeds treated with a bioactivator (T2), and a control without hydration or bioactivator (T3), with seven replicates and two independent evaluation cycles. The following parameters were analyzed: germination percentage, emergence, germination rate index, emergence rate index, seedling length, root length, and dry mass. The treatments with bioactivator significantly increased germination, with average values of 97.00% in T1 and 95.2 % in T2, higher than the control. T1 showed the best overall performance, with higher emergence percentages and consistent increases in germination rate, emergence rate, seedling length, root length, and dry weight in both cycles. Although T2 also outperformed the control, its response was lower than that obtained with pre-hydration. The results show that pre-hydration enhances the effect of the bioactivator; however, the scope of the study is limited to controlled conditions and the early stages of the crop, this practice may contribute to improving the uniformity, speed, and early vigor of maize.
