“…The present study revealed findings very different from the reports of Fonseca et al (2016). In their work on soybean in pots of 4.5 L, the fresh mass of the root system showed a 28.11 % rise in response to the application of a single 100 mL dose of manipueira.…”

“…The lowest manipueira dose used in this study (436.32 mL) applied to 10 L pots. It became clear that in proportion to the pot volume, this dose was nearly 50 % higher than the one employed by Fonseca et al (2016). Thus, the manipueira doses used in the cowpea crop by organo-mineral fertilization may have been too high and, possibly, damaging to the crop.…”

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.

Processing of cassava roots into flour or starch results in different waste products, which include a yellowish liquid referred to in Brazil as manipueira. This wastewater contains large quantities of cyanide formed from the hydrolysis of cyanogenic glycosides, which acts as natural plant defence. Studies conducted in Brazil over the past 30 years have looked into the possible applications of cassava wastewater in agricultural processes such as pest management. A number of studies have demonstrated its potential as a pesticide against nematodes, fungi and arthropods. Therefore, this byproduct of cassava production holds potential as a natural pesticide. Here we describe the cyanogenic glycosides of cassava and the factors that affect their content and cyanogenic potential in the plant and the chemical composition of cassava wastewater; we also review what is known about the effects of this effluent as a pesticide against arthropods and pathogens. Challenges for broader use and new avenues for further research on this topic are also proposed.
