Abstract

A study was designed to investigate the effect of cassava effluent on Okada environment. Two sets of same five plant species were germinated and watered with cassava effluent for 10 days at alternate days. One part of the effluent had read palm oil in it from processing while a part of it had non. Significant results were obtained from the one without red palm oil. Only Chlomolaena odoratasurvived out of the five plant species. The survival was 5% in 100% effluent concentration, 20% survival in 75% effluent concentration, 35% survival in 50% effluent concentration. While the control had 100% survival. Results from the effluent with red palm oil was not significant. Bad odour was perceived for a mean distance of 90.3 m from the point of discharge of cassava effluent. This is an indication of air pollution. The interview with ethno inhabitants showed that goats, sheep, die when they drink cassava waste water. There was no negative effect in respect of cat, pig, fowl and Turkey. Soil analysis showed that fungi were obliterated. The benefit from mycorrhizal association which enhances plant growth was lost. The study concluded that cassava effluent had negative effect on the Okada environment.  Enlightenment campaign, detoxifying cassava effluent in accordance with FEPA standard, appropriate method(s) of disposal of both solid and cassava waste water are recommended for safe and healthy Okada environment.         

Key words: Cassava effluent, Okada environment, mycorrhizal association, FEPA standard.
