Agricultural utilization of yellow waters associated with cassava wastewater is a sustainable technique, since it allows reduction of costs related to acquisition of industrialized fertilizers and minimizes the environmental pollution caused by the inadequate disposal of these effluents. In this context, this study evaluated the macronutrient macronutrient content and growth of cowpea fertigated with yellow water associated with cassava wastewater and NPK as source of nutrients. The experiment was set up in a greenhouse located at Campus I of the Federal University of Campina Grande. The experimental design was completely randomized, composed of five treatments characterized by: fertigation with mineral fertilizers, in the form of NPK; organic fertigation composed of human urine, cassava wastewater, human urine plus cassava wastewater; and organo-mineral fertigation composed of urine, cassava wastewater and mineral phosphorus, with four replicates. At 36 days after sowing, the following parameters were determined: contents of nitrogen, phosphorus, potassium, sulfur and the variables number of leaves, plant height, stem diameter, leaf area, shoot fresh matter and shoot dry matter. The use of yellow waters promotes significant increases for growth and production variables for nitrogen and potassium contents mainly, as well as for growth and production variables. The contents of nitrogen, phosphorus and potassium were higher than the levels considered as adequate for the cowpea crop. The use of human urine and cassava wastewater have potential to meet the needs for the main macronutrients required by cowpea and the irrigation via fertigation with these biofertilizers positively influences the development of cowpea.

O delineamento experimental foi inteiramente casualisado com quatorze tratamentos e quatro repetições, totalizando 56 parcelas. Os tratamentos foram: T1 (NPK), T2 (470 mL), T3 (670 mL), T4 (870 mL), T5 (1070 mL), T6 (1270 mL), T7 (1470 mL), T8 (F - NPK), T9 (F - 470 mL), T10 (F – 670 mL), T11 (F – 870 mL), T12 (F – 1070 mL), T13 (F – 1270 mL) e T14 (F – 1470 mL). Os volumes aplicados foram a combinação de urina humana + manipueira tratadas como adubação de fundação e fertirrigação (F). Foram avaliadas as variáveis de pigmento (clorofilas A, B, total e carotenóides), SPAD e °Brix. O tratamento T1 promoveu incremento de 43,94% no índice SPAD em relação ao T2. Mariores incrementos na concentração de sólidos solúveis totais foram obtidos para T1, T5, T7 e T8. O tratmento T13 promoveu valores máximos de clorofila A e total de 3843,703 e 5479,152 μgg-1 respectivamente. E para T14 os rendimentos máximos foram para as variáveis clorofila B e carotenoides (2805,197 e 333440,042 μgg-1). Os tratamentos influenciam positivamente todas as variáveis fisiológicas.

PHYSIOLOGICAL PARAMETERS OF CORN CULTIVATED UNDER ORGANIC FERTILIZATION OF NPK, YELLOW WATER AND CASSAVA WASTEWATER 2 ABSTRACT The aim of this study was to evaluate the physiological parameters of the hybrid corn AG 1051 grown in a protected environment in soil fertilized with human urine and treated cassava wastewater. The experimental design was completely randomized with fourteen treatments and four replications, thus totaling 56 experimental units. 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), T8 (F - NPK), T9 (F - 470 ml), T10 (F - 670 ml), T11 (F - 870 ml), T12 (F - 1070 ml), T13 (F - 1270) and T14 (F - 1470). The volume applied is the combination of human urine + cassava wastewater treated as foundation fertilization and fertigation (F). The production of chlorophylls A, B, total and carotenoids, SPAD and °Brix were evaluated. The T1 treatment promoted an increase of 43.94% in the SPAD index in relation to T2. Height increases in total soluble solids concentration were obtained for T1, T5, T7 and T8. The T13 treatment promoted maximum values of chlorophyll A and total of 3843.703 and 5479.152 μgg-1 respectively. For T14 the maximum yields were for the variables chlorophyll B and carotenoids (2805.197 and 333440.042 μgg-1). Treatments positively influence all physiological variables. Keywords: eco sanitation, human urine, liquid biofertilizer, reuse agriculture.

“…Among the residues, yellow water or human urine, stand out, since this liquid contains nitrogen, phosphate and potassium in the dissolved form in reasonable concentrations to meet the nutritional demands of the fertilized crops (Richert et al, 2010;Karak;Bhattacharyya, 2011;Botto et al, 2017). It accounts for approximately 56% of total phosphorus and 80% of total nitrogen found in domestic wastewater (Spångberg et al 2014;Chipako;Randall, 2020).…”

Most of the nutrients that are essential for crops, mainly nitrogen, phosphorus and potassium, are found in human urine in sufficient quantities, and in most cases, they are more adequate and sustainable even when compared to commercial chemical fertilizers. This work evaluated the growth of sunflower (Helianthus annuus L.) and coriander (Coriandrum sativum) submitted to the use of human urine as a biofertilizer. A treatment was carried out in the urine using the storage method, as a way to decontaminate pathogens. The experimental design used was a randomized block, with 5 treatments and 4 replicates, which were: T1 -only water; T2 -water + 15% urine; T3 -water + 30% urine; T4 -water + 45% urine; and T5 -water + 60% urine for sunflower cultivation. In relation to coriander, it was used in T1 -only water; T2 -water + 5% urine; T3 -water + 10% urine; T4 -water + 15% urine; and T5 -water + 20% urine. The experiment evaluated for sunflower and coriander the following: stem diameter (SD); Plant Height (PH); Leaf number (LN), Root length (RL) and Total Dry Mass of the Plant (PDM). The T1 and T2 treatments in sunflower cultivation showed higher mean values of SD, PH, LN and PDM. The T2 treatment in the cultivation of coriander showed greater development in relation to the variables SD, PH, LN and PDM. Thus, the results indicate that the crops were able to absorb the nutrients contained in human urine, demonstrating that it is possible to replace chemical fertilizers, causing a reduction in their consumption.
