    The purpose of this study was to analyze the efficiency of a hand tool for weeding and ridging in corn (Zea mays L.) cultivation in Nero, Azuay, for which three specific objectives were established. First, soil characteristics before crop establishment (AEC) and after hilling (POST/AP) were compared to evaluate any significant changes caused by the use of the hand tool. Secondly, phenological behavior was evaluated at three planting densities, d1(0.50m), d2(0.75) and d3(1m) between rows, to determine the influence of this on crop development. Finally, production costs were estimated, using the manual tool T2 (furrower), compared to traditional tools T1 (hoe), to evaluate the economic viability and efficiency of the use of this tool. The results showed that, for seven parameters of the physical-chemical properties of the soil evaluated, the %MO was the only variable that presented significant statistical differences in relation to the treatments T1 and T2, on the other hand, the densities d3 presented significant differences in plant height, number of leaves and stem thickness as opposed to d1 and d2, so T2 had greater time efficiency compared to T1, in relation to production costs. Analyzing this study allows opting for alternatives to improve labor productivity in the cultivation of corn (Zea mays L.) in Nero, Azuay
