Growth of maize (Zea mays L.) and changes in some chemical properties of an ultisol amended with brewery effluent

Abstract

A greenhouse studies was conducted at the University of Benin, Benin City, Nigeria to evaluate the effect of brewery effluent on some soil chemical properties and growth of maize. The experiment, which was organised in a completely randomised design, had three replications with 0, 25, 50, 75 and 100% effluent concentration in a 2 kg soil. Results showed that organic carbon, N, P, Na, and Mg concentration in the soil were reduced while K, Ca, C/N ratio, soil pH were increased. There were no changes observed in the soil textural class. The growth of maize plant as well as chlorophyll content was enhanced with brewery effluent treatments when compared with the control.
