Abstract

Fertigation system by using drip irrigation is one of the famous method or technique that will use in agriculture especially for chili, and also leafy vegetable. Rainfall is the natural water source that comes from water cycle from the water on surface to sky and from sky back to surface as called rainfall. Due to waste of vegetable and also waste of food consumption at home, the combination of waste by rainfall water can be used as bio-fertilizer or plant booster by process of fermentation to overcome the waste and rainfall water problems. This study intends to analyze the different physical properties changes in between treated with bio-fertilizer and untreated on lettuce Lactuca sativa growth performance. Result show the application bio-fertilizer + chemical fertilizer is showing more positive in growth performance compare to T1 (Control- soil + chemical fertilizer +rainfall). Statistically, there is significant different was observed between treatments with high different showing effect each treatment. This study suggested positive effects of bio-fertilizer + chemical fertilizer + rainfall on growth performance of lettuce and recommend that much studies should be conducted to broaden the scope of study.
