ABSTRACT
Soils of southeast Nigeria are predominantly acidic, sandy, and physically fragile. They are also deficient in organic mailer, nitrogen and basic callous. Because of unavailability, imbalanced nutrition and other problems associated with use of chemical fertilizers, it is necessary to intensify studies into locally available, adoptable organic soil management strategies to stabilize and improve physical conditions of the soils, their chemical fertility and productivity. Hence three field experiments were carried in two sites Umudike (in the rainforest zone) and lgbariam (in the derived savanna zone) to study the separate and combined effects of wood ash and residues of leguminous food crops on soil physical and chemical properties, growth and yield of maize (Zea inays). 'l'he first experiment involved the died of crop residues on soil pr0pec1ies. 'l]ie treatments consisted of residues of groundnut (Arachis hypogea L), cowpea (Vigna ungulculala M. Waip), soybean (Glycine max (L.) Merr.), 'akidi' (Vigna ungulculala sub- species dekintiana) and natural fallow. In the second experiment, the effect of different levels of wood ash (0, 2, 4, 6 and 8 t had) was investigated. In third experiment, the effect of separate and combined inputs of wood ash and groundnut residue, and 300 kg ha NI'K I 5 -- IS — IS fCrtilizcr was studied. Treatments were replicated three times in a randomized complete block design and experiments were conducted lr two years.
