Abstract

Observations at Ile-Ife (7o28’N 4o33’E and 244m above sea level) in the rainforest ecology of South-Western Nigeria suggest that the global climatic change has resulted in the shortening of the growing season for maize (Zea mays L.)… Several newly developed late maturing varieties are available but had not been evaluated under the late season conditions of the rainforest ecology as typified by the Teaching and Research Farm of Obafemi Awolowo University, Ile-Ife. This study was conducted to evaluate 36 recently developed varieties of maize under the late season conditions of the rainforest ecology. The varieties were planted September 3, 2006; August 8, 2007 and September 13, 2007. For purposes of comparison, a fourth trial was planted on May 20, 2008 under early season conditions. Each trial was laid out in a 6 × 6 lattice design with three replications. Mean yield was 1.6 tons/ha for the two September plantings (Late seasons), 1.8 tons/ha for August planting (Late season) and 3.4 tons/ha for May planting (Early season). Mean squares for environment, varitety and Variety × environment interaction were statistically significant for ear number, ear weight and yield per plot. The highest yielding variety across all environments was LNP-WXLNTPF1 (2.91 tons/ha).The best varieties for August planting are TZLCOMP.IC4 (3.31 tons/ha), LNP-WXLNTPF1 (2.89 tons/ha) and the widely grown variety TZB-SR (2.46 tons/ha).. It was concluded that planting of the late maturing varieties of maize should not be delayed beyond the last week in August for optimum yield.
