“…Duarte et al (2012) obtained a maximum plant dry biomass of 4.86 g plant -1 at a dose of 45 m 3 ha -1 of cassava effluent on lettuce. Dantas et al (2015) achieved the minimum (18.35 g plant -1 ) and maximum (56.80 g plant -1 ) accumulation of dry biomass in sunflower with the application of the smallest and largest doses of the cassava residue, respectively, which is in accordance with the results achieved in the this study. However, Santos et al (2012) found no significant difference in dry biomass of crambe with the application of increasing doses of K 2 O.…”

“…However, they can be efficiently used in agriculture to promote soil fertility and treat nutritional deficiency, because they are rabidly absorbed by plants (Nobile & Mussi, 2013;Magalhães et al, 2014). Dantas et al (2015) evaluated the growth of sunflower using cassava effluent and found that the factors related to plant growth increased with greater applied doses of this effluent. Magalhães et al (2014) investigated the use of the same effluent to promote the development of corn, confirming that it can be used as a source of fertilizer whose efficiency depends on the use of appropriate doses of the residue.…”

This study aimed to evaluate the effect of applying increasing doses of biofertilizer obtained by the anaerobic digestion of cassava effluent on the development of crambe plants. The experiment was conducted in a protected environment at the Federal University of Paraná (UFPR), Palotina Sector, between April and August 2015. A completely randomized design was used, and five different treatments with the following doses were applied in five replicates: 0, 40, 80, 120, and 160 kg ha-1 of K2O. The following parameters related to plant development were evaluated: final height, stem diameter, number of branches, dry shoot and root biomass, mass of the grains, and oil content. The 160 kg K2O ha-1 dose was found to have the best influence on the plant development, because all the measured parameters reached their highest values at this dose, except for oil content, which attained the highest percentage in the case of the control treatment (0 kg ha-1 of K2O). This study proved that the biofertilizer obtained by anaerobic digestion of cassava effluent can be used as an alternative to regular fertilizers in cultivating crambe.

“…From this perspective, the waste which would otherwise be dumped and negatively affect the environment, can find use as a nutrient source in the community, assisting small farmers, and enriching the local production. In Brazil, cassava is primarily used as alternative source of fertilizer for crops, animal feed, as well as a control measure of plant diseases and pests (Gonzaga et al, 2008;Dantas et al, 2015;Santos Filho et al, 2015). This concept of profitably utilizing waste has grabbed considerable attention as a method of minimizing the negative environmental impacts caused by the disposal of waste.…”

The use of manipueria (the organic wastewater from the cassava flour manufacturing process) is a promising management strategy in agriculture because it is a rich nutrient source for plants. Thus, this study aimed at evaluating the use of manipueria as a fertilizer for sunflower cultivation. The field experiment was carried out in a randomized complete block design with 6 treatments (doses of cassava: 0, 8.5, 17, 34, 68 and 136 m 3 ha -1 ) and four replications, using the sunflower cultivar Helio 250. The experiment was collected at 90 days after sowing. We evaluated the shoot fresh and dry mass, achenes and oil yield, nitrogen, phosphorus and potassium content in leaves, stem, chapter and achenes. Data were initially submitted to analysis of variance at 5% significance level and then to regression analysis. The manipueira wastewater application significant increased fresh and dry mass accumulations in shoot, content of nutrients such as nitrogen, phosphorus and potassium in plant, as well grain and oil yields. The dose of 136 m 3 ha -1 resulted in the highest fresh and dry mass production in shoot and greater macronutrient accumulation supplying enough nitrogen, phosphorus and potassium to the plant, confirming the potential as an organic fertilizer. The 4562.52 and 1965.19 kg ha -1 in achene and oil, respectively, obtained with the use of manipueira wastewater,yields are above the sunflower national and international average production.

“…Quanto ao uso agrícola da manipueira, Dantas et al (2015) objetivando, avaliar o crescimento do girassol fertilizado com manipueira, concluíram que o uso do efluente proporcionou um desenvolvimento mais adequado das plantas e recomendaram seu uso como fonte de nutrientes para a cultura estudada. Duarte et al (2012) e Santos et al (2010), analisaram o uso da manipueira no cultivo da alface e concluíram que o efluente serviu como fonte de adubação para a cultura.…”

RESUMOUso agrícola de águas amarelas e manipueira é uma opção atrativa do ponto de vista econômico, em razão da ciclagem dos nutrientes e redução de custos com aquisição de fertilizantes minerais. Este trabalho objetivou avaliar a produção da alface Crespa Cristina cultivada em substrato fertirrigado com urina humana e manipueira tratadas por processo de digestão anaeróbica, como fonte alternativa de fertilizante. O experimento foi conduzido em casa de vegetação, o delineamento experimental foi o inteiramente casualizado, composto por oito tratamentos e três repetições. Os tratamentos consistiram por apenas o substrato (Testemunha); e o substrato fertirrigado com solução mineral composta por NPK, urina humana, manipueira, urina humana mais manipueira, duas vezes a dose de urina humana, duas vezes a dose de manipueira e duas vezes a dose de urina humana mais manipueira. O substrato foi composto por solo e esterco bovino não curtido na proporção de 2: 1 v/v. Aos 38 dias após o transplantio foram avaliadas número de folhas, altura de plantas, diâmetro caulinar, massa fresca da parte aérea, massa fresca comercial, massa seca da parte aérea e raízes da alface. A análise estatística indicou que só não houve diferença estatística significativa para a variável altura de planta. As maiores médias foram obtidas através do substrato fertirrigado com urina humana mais manipueira, duas vezes manipueira e duas vezes as doses de urina humana mais manipueira, respectivamente. Concluiu-se que tanto as doses duplas de manipueira e a associação dos dois efluentes apresentam potencial fertilizador para a cultura da alface, podendo ser utilizados como fonte de nutrientes.
