    Abstract: The agricultural reuse of wastewater is already a reality in several countries of the world. The objective of this work was to evaluate the growth of hybrid corn AG 1051 grown in fertilized soil via the foundation and fertirrigation with the combination of human urine and treated cassava and NPK in protected environment.The experiment was conducted at the Federal University of Campina Grande, Campina Grande, Paraíba. The experimental design was the completely randomized one with 14 treatments and four replications, being two experiments, one fertilized via foundation and the other via fertigation. The treatments were as follows: T1 (NPK), T2 (470 mL), T3 (670 mL), T4 (870 mL), T5 (1070 mL), T6 (1270 mL), T7 (1470 mL) applied via fertilization of fertirrigado, and the same dosages applied via fertirrigation corresponding to T9 mineral fertilization, and T10, T11, T13 and T14 the different doses of organic fertilization. There was an average increase of 17.32% in the Index of Emergency Speed for the seeds that were cultivated in soil fertilized with T3 and T4 in relation to the one fertilized with NPK (T1), the soil fertilized with T3 was the one that presented the highest %E (Emergency Percentage) with 98, 81%. At 15 days after the emergency (DAE), the chemical fertilization through the foundation promoted greater leaf area gain differently than at 65 DAE. The organic fertilization via fertigation promoted the highest gains for absolute and relative growth rates of plant height stem diameter and number of leaves.

    Abstract: RESUMO Este trabalho objetivou avaliar os teores dos macronutrientes (NPK e S) e o crescimento do milho ‘Potiguar’ fertigado com urina humana, manipueira e suas associações com NPK. O experimento foi instalado em casa de vegetação localizada no Campus I da Universidade Federal de Campina Grande. Utilizou-se delineamento experimental inteiramente casualizado, composto por oito tratamentos, correspondentes a fertigação com fertilizante mineral na fórmula de NPK; orgânica composta por urina humana, manipueira e água amarela associada à manipueira; organonomineral composta por urina humana adicionada de fósforo e potássio, manipueira mais nitrogênio e fósforo e urina humana associada à manipueira mais fósforo, com cinco repetições. Aos 50 dias após a semeadura (DAS) foram avaliados os teores foliares de NPK e S e as variáveis de crescimento: número de folhas, altura de planta, diâmetro caulinar, área foliar, massa fresca e seca das folhas, massa do caule e da parte aérea. Os teores de N e P, e as variáveis de crescimento: número de folhas, altura de planta, massa fresca e seca das folhas, massa do caule e da parte aérea foram influenciados pela fertigação com urina humana, manipueira e suas associações com NPK. Nas folhas do milho ‘Potiguar’ os teores acumulados de N, P, K e S, aos 50 DAS, variaram na sequência N 〉 K 〉 P 〉 S. A urina humana tem potencial como fonte de N na fertigação do milho e a manipueira pode ser utilizada se associada a outras fontes de nutrientes.

    Abstract: Chemical fertilizers have been increasingly used in agriculture. The application of these nutrients via irrigation water has been evaluated in order to obtain productive results in agricultural yield. The objective of this research was to evaluate the effect of nitrogen (N) doses, applied by fertigation and associated with different types of basal fertilization, on the growth and production of beet. The experiment was conducted at the Federal University of Campina Grande (UFCG), in a protected environment belonging to the Academic Unit of Agricultural Engineering (UAEA). The adopted statistical design was completely randomized blocks, with three replicates, and the factors were arranged in a 5 × 3 factorial scheme, corresponding to five N doses (0, 50, 100, 150 and 200 mg dm-3 of soil), and three types basal fertilization (soil without fertilizer, earthworm humus, earthworm humus + NPK). At 45 days after transplanting, the number of leaves per plant, plant height, stem diameter, leaf area, green intensity, bulb diameter, stem length, bulb fresh weight, bulb dry weight and total soluble solids (°Brix) were quantified. Both Soil basal fertilization significantly influenced beet growth and production, and the treatment with earthworm humus and earthworm humus + NPK led to the best results for the analyzed variables. The highest N dose promoted the best performance for stem diameter and content of total soluble solids (°Brix).
