“…The pH values observed in the 10 to 20 cm layers are in agreement with those obtained by Barreto et al (2013), Duarte et al (2013), Dantas et al (2014) and Magalhães et al (2015), when studying the pH response on the application of increasing doses of cassava wastewater in different soils, observed a positive linear effect on the pH values. On the other hand, Cabral et al (2010) did not observe a significant difference of pH with the application of doses (0 to 600 m 3 ha -1 ) of cassava wastewater in the layers of 0.5 to 10 and 10 to 20 cm.…”

“…Barreto et al (2013) also found a positive linear effect for exchangeable potassium in the soil when doses of up to 216 m 3 ha -1 of tap water were applied. Duarte et al (2013) observed an increase in the exchangeable potassium concentration in the soil with an increase of doses of cassava wastewater from 0 to 65 m 3 ha -1 , a tendency similar to the results of studies by Melo et al (2005) and Magalhães et al (2015).…”

“…Similar results were found by Duarte et al (2013), which showed an increasing linear effect for the available phosphorus concentration of a Neosol after the application of increasing doses of cassava wastewater. Barreto et al (2013) and Magalhães et al (2015) also reported an increase in available phosphorus of about 60% in the soil due to the increase of cassava wastewater.…”

There is a worldwide concern regarding the management of agroindustrial residues, involving sustainable practices that contribute to taking advantage of the residues as inputs in productive processes, allowing greater efficiency in the integration of agricultural activities and mitigating their adverse effects on the soil. Therefore, the objective of this study was to assess the effects of application of cassava wastewater on the chemical attributes of the soil cultivated with Brachiaria brizantha cv. Marandu. The experimental design was in randomized blocks with five treatments (0, 15, 30, 60 and 120 m³ ha-1 of cassava wastewater) and four repetitions. To characterize soil chemical attributes soil samples were collected at depths 0 to 10 and 10 to 20 cm, for determination of the concentrations of soil organic matter, available phosphorus, exchangeable potassium, sodium, calcium and magnesium before and after cassava wastewater application were determined. The application of cassava wastewater increases available phosphorus and exchangeable potassium concentrations, decreases exchangeable calcium, magnesium and organic matter contents of the soil cultivated with Marandu grass. Cassava wastewater can be used as organic fertilizer for pastures of Marandu grass with doses of up to 120 m³ ha-1.

“…With the application of the total dose (second cut), this effect became more evident, with higher LAI and mass of leaf blades. Magalhães et al (2015) observed reduction in the mass of leaf blades with high doses of wastewater in the maize crop, because this plant, with greater availability of nutrients, entered more rapidly in the reproductive stage, a behavior not observed in the 'Marandu' grass. According to Magalhães et al (2016), cassava wastewater doses from 75.6 m 3 ha -1 on cause toxic effect on maize plants, with burning of leaf tips due to the high potassium content.…”

“…Authors such as Marini and Marinho (2011), Dantas et al (2017) and Magalhães et al (2015) evaluated the use of manipueira as a source of nutrients in agricultural crops. However, there are few comparative studies between manipueira as organic fertilizer and chemical fertilizers, involving cowpea bean.…”

The alarming increase of utilization of chemical fertilizers for crops has stimulated the quest for organic residues with the potential for enhancing agricultural products. The manipueira is a liquid residue produced in the process of making flour or starch from cassava (Manihot esculenta Crantz.) with potential for use as agricultural fertilizers because of its rich macronutrient (K, N, Mg, P, Ca and S, in the quantitative order) content and with sufficient contents of all micronutrients except molybdenum. Thus, the objective of this work was to evaluate the initial development of cowpea bean (Vigna unguiculata (L.) Walp., cv. Corujinha) fertilized with mineral fertilization and manipueira. The research was performed between January and February 2017, in a greenhouse located in the city of Campina Grande (7º 13'50" S, 35º 52'52" W, 551 m asl), state of Paraíba, Brazil. The experimental design was completely randomized, involving 8 treatments and 3 replicates, totally 24 experimental units. The treatments included applying mineral fertilization using phosphorus; potassium; phosphorus and potassium in combination; organo-mineral fertilization with phosphorus and manipueira; and phosphorus combined with manipueira in different proportions (25, 50, 75 and 100 % of the manipueira recommended doses). Stem diameter, plant height, number of leaves, fresh shoot biomass and dry biomass of the aerial parts of the plant, fresh root biomass and dry root biomass were determined at 15 days after sowing. Data were subjected to the analysis of variance by F-test and the averages were compared by Tukey's test (p < 0.05). The results showed significant differences between the treatments evaluated. The most significant increases in bean growth and phytomass accumulation were occurred upon mineral fertilization with phosphorus on stem diameter, plant height, fresh shoot biomass and fresh and dry root biomass. Plants subjected to fertilization with phosphorus and different doses of manipueira exhibited a negative effect on the initial development stage of the cowpea (V4 stage) and it is not recommended as a substitute for the mineral fertilization for this culture in this period.
