The second factor was the of NPK fertilizer (0, 100 and 150 kg.ha-1) which consist  of nine treatments combination. The observed parameterswere  the height of the plant (cm),  the days of flowering (days), the days of harvesting (days), the  fruit length (cm), the fruit diameter (cm), the number of fruits per plant (fruit), the fruit weight per fruit (g), the fruit weight per plant (g) and the fruit weight with plot (g). The data  in this research was analyzed in using variance and followed by Duncan's multiple distance test at 5% level.  The results showed that tofu waste compost and NPK fertilizer increased the growth of eggplant such as  the height of the plant,  the days of flowering, the days of harvesting, the number of fruits per plant, the fruit length, the fruit weight per fruit, the fruit weight per plant and the fruit weight with plot and does not increase fruit diameter. The giving tofu waste compost at a dose  20 ton.ha-1  and NPK fertilizer 150 kg.ha-1  gave the best eggplant growth and production until the plants were 90 DAP
