The nutrition of onion grown in a no-tillage system with compost requires
research to provide alternatives to mineral fertilizers. Our objective was to
evaluate the effect of compost rates on the nutrient content in the tissue of
onion grown in a no-tillage system. We conducted a field experiment with
the following treatments: 0, 10, 20, 30, and 60 Mg ha&#8722;1 of compost and
mineral fertilization. We applied these treatments in 2018, 2019, and 2020
for onion cultivation. We used a 3 × 6 factorial scheme (year x treatment) and
four replications. We evaluated the bulbs and whole plant nutrient contents
of N, P, K, Ca, Mg, S, Fe, Mn, Zn, Cu, and B. In 2020, nutrient content in the
bulb from 10 Mg ha&#8722;1 of compost was similar to the mineral fertilizer?s
treatment. Therefore, compost can replace mineral fertilizers to supply 
nutrients to the onion. However, the continuous application of compost requires
soil monitoring due to nutrient accumulation.
