    One of the alternative methods for weed control is soil mulching. Mulches influence weed germination and growth by blocking the daylight. Soil surface can be mulched by different materials. Such as organic materials. The objectives of this experiment were to evaluate the effect two organic mulches Pueraria javanica and the palm oil stem compost (Elaeis guenensis) on Borreria alata. In this study with thicknesses (2.5, 7.5 and 12.5 cm) and an unmulched. The observed data was analyzed using Analysis of Variance (ANOVA) and the significant differences among the treatment means were determined using Duncan’s Multiple Range test with probability level of P=0.05. The results showed that all organic mulches lessen weed germination and growth. Mulch of Pueraria javanica with thickness 2.5 cm reduced weed germination as 76.29% and growth as 44.26%. Palm oil stem compost (Elaeis guenensis) with thickness 2.5 cm had the strongest influence on the decrease of weed germination i.e 86.60% and growth i.e 32.79%. The 7.5 cm and 12.5 cm thickness mulching with Pueraria javanica and Palm oil stem compost (Elaeis guenensis) didnot germinate weeds
