Abstract

A screen house experiment conducted in Rivers state university teaching and research farm and crop/soil science laboratory, to evaluate the effect of different organic lime materials as an amendment for an acid potting soil for maize (Zea mays) nursery. The lime materials used were egg shell, snail shell, oyster shell, wood ash. Calcium carbonate was used as a basis for comparison and no lime was used as control for all the limes. Results showed that all the different lime materials used appreciably raised the soil pH. Application of the different lime materials showed no significant different among the lime materials but with no lime having the lowest pH value OF 6.2, when compared to the of value pH of the other treatments. The lime materials positively affected all the plant parameters measured. Result showed that white maize variety had the highest percentage germination (89.6%), when compared to the two improved varieties (oba 98 and oba super6); 85.4%, with the yellow local variety having the least % germination of 66.7%. Generally, the combined effect of the different lime materials and maize varieties, showed significant differences (P< 0.05) among plant parameters measured; across the four weeks. Results also showed the effect of the liming varied with both the type of liming materials and the crop variety.
