The zucchini is used mainly for consumption in fresh fruit; it is rich in vitamins and minerals. For its production, high amounts of chemical fertilizers (CF) are applied, which increase production costs and cause ecological damage. In general, CF present low efficiency that could be increased with the use of products such as zeolite. As far as Apatzingan Michoacán, it was planted in zucchini field in December of 2017, to determine the effect of the application of zeolite (Z) as a percentage of the CF dose on production and economic profitability. The treatments were evaluated: 100CF, 25Z + 75CF, 50Z + 50CF, 75Z + 25CF, 100Z, 0Z + 0CF (the values represent percentages). It was found that the time to occur of the phenological stages was not modified by the treatments, the emergence occurred nine days after sowing (dds), flowering at 39 days, the first cut of fruits at 48 days and at 71 days the last cut. The supply of zeolite in mixtures with CF did not reduce plant height, stem diameter and number of leaves compared to the full dose of CF. The mixture that generated the highest yield of fresh fruit (37.8 t ha-1) and gain per peso invested ($3.44) was 25Z + 75CF. So, in zucchini the application of zeolite allows to reduce the dose of CF with the consequent increase in yield and economic profitability.
