Linear measurements of the length and maximum width of terminal leaflets of mungbean (Vigna radiata (L.) Wilczek) were made to estimate the whole trifoliate leaf area. The linear measurements were compared with the areas of leaflets and whole trifoliate leaves, determined using a leaf area meter. Five varieties were used in the study. Varieties differed in leaf shape and size, and equations were generated for each of the varieties to estimate the leaf area as a function of the product of the length and maximum width of the terminal leaflets, thus providing a means of nondestructive estimation of leaf area.
