EFFECTS OF CASSAVA MILL EFFLUENT ON THE GROWTH OF PUMPKIN PLANTS | Journal of Global Agriculture...
Cassava processing mill wastes are typically dumped uncontrollably into the environment, posing major environmental risks. The goal of this study was to examine the effects of cassava mill effluent on soil microbiological quality as well as the effects of polluted soil on plant growth. Effluent from a cassava mill. Soil samples that were not polluted were collected and microbiologically tested. Pumpkin plant germination and growth were also studied using soil samples polluted with various amounts of cassava mill effluent. Staphylococcus aureus, Bacillus spp, Streptococcus spp, Pseudomonas aeruginosa, Aspergillus spp, and Candida spp were found in the effluent microbial population. The fungal count was 1.1x103cfu/ml, while the bacterial count was 1.4x104cfu/ml. The effluent had a considerable effect on the physicochemical and microbiological properties of the soil, according to the results of the tests of the unpolluted soil and the effluent polluted soil samples. For bacteria, the overall microbial count grew from 2.2x105cfu/g to 4.6x105cfu/g, while fungi climbed from 1.6x104cfu/g to 3.3x105cfu/g. The microorganism diversity was higher in the polluted soil. At greater amounts of wastewater, the polluted soil also impeded plant germination. Irrigation of healthy developing plants with 100 percent effluent concentration resulted in the plants wilting within a few days. The effluents from cassava processing mills have considerable influence on the physicochemical and microbiological qualities of the surrounding soils, as well as negatively affecting plant growth on these soils, according to this study. As a result, it was proposed that this effluent be appropriately treated before being discharged into the environment.
