Resumo: | ABSTRACT This study aimed to evaluate the contents of macronutrients (NPK and S) and the growth of ‘Potiguar’ corn fertigated with human urine, cassava wastewater and their associations with NPK. The experiment was set up in greenhouse located on Campus I of Universidade Federal de Campina Grande. A completely randomized experimental design was used, consisting of eight treatments, corresponding to fertigation with mineral fertilizer NPK formula; organic, composed of yellow water, cassava wastewater and human urine associated with cassava wastewater; organomineral, composed of human urine associated with phosphorus and potassium, cassava wastewater associated with nitrogen and phosphorus and human urine associated with cassava wastewater and phosphorus, with five repetitions. At 50 days after sowing (DAS), plants were evaluated for the leaf NPK and S concentrations and growth variables: number of leaves, plant height, stem diameter, leaf area, fresh and dry mass of leaves, mass of stem and shoots. Nitrogen and phosphorus concentrations and the growth variables number of leaves, plant height, fresh and dry mass of leaves, mass of stem and of shoot were influenced by fertigation with human urine, cassava wastewater concentrations and their associations with NPK. In the leaves of corn cultivar Potiguar the accumulated concentrations of N, P and K, at 50 DAS, varied in the sequence N &gt; K &gt; P. Human urine has potential as source of N in fertigation of corn and cassava wastewater can be used if associated with other sources of nutrients.
