Potato (Solanum tuberosum, L.) is one of the most responsive crops to fertilizer application, which drives the
need to rationalize and make the most of nutritional resources in efficient and sustainable management. Based
on the hypothesis that the organomineral is a great alternative to increase potato productivity (Ágata and
Atlantic cultivars) and that it can be indicated as a substitute for mineral fertilizers, this study aims to evaluate
the effect of organomineral doses applied in the planting furrow on potato productivity to identify the best
level of mineral fertilizer replacement. A study was conducted in the city of Cristalina (state of Goiás, Brazil),
evaluating the replacement of 40, 60, 80, and 100% of mineral fertilizer (standard) provided via organomineral
fertilizer in two widely cultivated varieties. The total productivity and the productivity in classes were monitored,
as well as the nutrient contents in the leaves. The results showed that the organomineral is a great alternative to
increase potato productivity and can be indicated as a substitute for mineral fertilizers. For the cultivar Ágata,
an organomineral dose of 80% is recommended concerning mineral fertilization. On the other hand, for the
Atlantic cultivar, the same dose of mineral fertilizer is recommended. In both cultivars, there was an increase in
tuber size with organomineral fertilization, which indicates greater efficiency in tuber productivity.
