Influence of rice husk dust on exchangeable bases and acidity of an ultisol and maize growth in abakaliki, south eastern nigeria
Journal Title: Scientia Agriculturae - Year 2016, Vol 13, Issue 3
Abstract
An experiment was carried in 2012, 2013 and 2014 cropping seasons at Teaching and Research Farm of Faculty of Agriculture and Natural Resources Management, Ebonyi State University, Abakaliki to evaluate the effects of rice husk dust on exchangeable bases, total exchangeable bases, total exchangeable acidity, effective cation exchange capacity, base saturation and maize growth in Abakaliki South Eastern Nigeria. The experiment was laid out in randomized complete block design (RCBD) with sixteen treatments replicated three times. Data collected were analysed using the General Linear Model of SAS software in RCBD.There was significant (P < 0.05) increase in exchangeable bases, total exchangeable base, effective cation exchange capacity, base saturation, maize growth and a significant (P < 0.05) decrease in total exchangeable acidity in rice husk dust amended plots relative to control. Unburnt rice husk dust significantly increased exchangeable bases than burnt rice husk dust in the amended plots. Equally, Unburnt + burnt rice husk at the rates of 10 and 15t ha-1 gave the highest value of the exchangeable cations. This study recommended that rice husk dust being cheaper than other fertilizers in the study should be used as soil amendments to increase soil productivity.
