The green onion is one of the condiments species most used in the world, and the growth is mostly done by family farmers. The work was done in the municipality of Jandaia do Sul, in the state of Parana, on the Angelina farm, located in the rural area of amizade road. This work aimed to evaluate the productivity of the crop with the fertilizers through different nutrient sources, comparing which would bring better results. A complete randomized design was used with five treatments and five repetitions. The treatments were composed by control, fertilizing with cattle manure, poultry manure, triple overdoses and potassium chloride. Using five plant beds of 13,5 m long and 1 m wide each. The spacing utilized was of 25 cm among plants and 20 cm among rows, totaling 4 rows with a population of 40 plants in each block. The cutting of the plants was done when they reached their maximum plant growth (90 days). Fresh weight, dry weight and length were evaluated. The growth with organic fertilizers brought positive results and the most satisfactory was the treatment with cattle manure where the plants gained higher height and higher weight of fresh mass and dry mass compared to the other treatments. At the beginning of growth with poultry manure the plants took time to adapt due the acidity of the compound, but after they stabilized there was a fast initial growth. The treatments with sources of phosphorus and potassium did not brought positive results in any evaluation.
