Plastic mulch (200 p,rnI0.2 rom thick) and 4- CPA interaction on growth and yield of African eggplant (Solanum aethiopicum L.) cultivar 'Legon Prolific' were investigated in the field during two summer seasons, 1994 and 1995. Four mulch treatment; black, black and white (white on the upper surface), transparent and control and three 4-CPAconcentrations; 0 ppm, 15 ppm and 30 ppm were used. Plant height (cm) was highest in the transparent mulch treatment and lowest in the control in both years. Plastic mulch and 4-CPA independently had significant effects (P 0.05) on fruit yield and number of eggplants. Significant differences between plastic mulch x 4-CPA interaction were observed in fruit yield, number and fruit size. Plants treated with transparent mulch and 4- CPA produced the highest fruit yield and number in both years. The experiment indicated that eggplant productions is best under the combination of plastic mulch and 4-CPA hormone application. The combination of transparent mulch and the low rate (15 ppm) of 4- CPA produced the highest fruit yield.
