Abstract
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
