Abstract
To facilitate estimating plant leaf area of maize (Zea mays L.) for researchers working on this crop, two tables were prepared for direct leaf area estimation. Tables prepared were put into two groups of maize cultivars, namely, cultivars of 14 + 1 functional leaf per plant and cultivars of 11 + 1 functional leaf per plant. To get plant leaf area directly from these tables, the reader needs the length of the leaf located directly below ear leaf of his cultivar, and find plant leaf area opposite to the leaf length. The first table was for cultivars have 14+1 leaf per plant, while the second table for cultivars have 11 + 1 leaf per plant. The first table relied on a formula to estimate plant leaf area = 0.65×L2 ,and the second table on formula that plant leaf area = 0.75×L2, when the L2 = length of leaf below ear leaf. Using these tables will facilitate maize plant leaf area estimation and make it much faster to the researchers.
