Strawberry crop is part of the world market as an important alternative to agricultural diversification. The mineral nutrition is closely related to production quality, but there are some questions on plant nutrition and strawberry fruit quality relationship. Thus, studies related to strawberry plants mineral nutrition contribute to a better understanding about this crop. In this sense, the current study aimed to evaluate the effects of nitrogen and potassium fertigation in strawberry crop under field conditions on chemical properties and fruit external color rates. The experiment was carried out at UFLA, Lavras, MG, Brazil, using a randomized blocks experimental design, replicated three times, in a 4x4 factorial scheme. Four nitrogen doses (100, 200, 300 and 400 kg ha-1) and four potassium doses (150, 300, 450 and 600 kg ha-1 of K2O) were applied using urea and potassium chloride as respectively sources of nutrients. Strawberry plants from cultivar Aromas were used. Our results shown that strawberry fruit chemical properties and fruit external color rates are influenced by both, nitrogen and potassium fertigation, varying according to the studied property.
