The experimental design was factorial in randomized completely block design with three replications. The result showed the effect of water source to spray vegetables and frequency insecticide spray not significant on the growth vegetables, but significant on Pb contain in vegetables. The maximum Pb (7,97 ppm) in sludge from household and twice insecticide spray.Keywords: Water source, frequency insecticide, Heavy metal Pb, vegetable.
