Pemanfaatan Mulsa Organik Pueraria javanica dan Kompos Pelepah Kelapa Sawit Terhadap Penghambatan Perkecambahan dan Pertumbuhan Anakan Gulma Borreria alata (Aublet) DC

Abstract

The objectives of this research is to evaluate the effect of two organic mulches of Pueraria javanica and the palm oil
stem compost with different thickness on seed germination and growth of Borreria alata. The observed data were
analyzed using Analysis of Variance (ANOVA) and the significant differences among the treatment means were determined
using Duncan’s Multiple Range test with test level 5%. The results showed that all organic mulches decreased B. alata
germination and growth germination and growth. Mulch of Pueraria javanica with thickness of 2.5 cm reduced weed
germination as much as 76.29% and growth 44.26%. Palm oil stem compost with thickness of 2.5 cm gave the significant
effect 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 P. javanica and palm oil stem compost gave no germination of weeds.
