Abstract

The objectives of this research were to find out the efficacy of metsulfuron methyl
herbicide to weeds of unproductive yet oil palm, to find out the growing weeds
composition change after application, and to findout the influence. This research was
conducted in randomizedgroup design with 8 treatments of metsulfuron methyl
dosages of 15, 20, 25, 40, and 50 h.ha-1
, mechanical weeds removal, with control, and
4 repetitions. Variance homogeneity was tested with Bartlett test and data addition
was tested with Tukey test. Differences in median tested using Least Significant
Differenc (LSD) level 5%. The results showed that: (1) 15 to 50g.ha-1
metsulfuron
methyl dosages were effective to oppress total weed scovering, total weeds toxicity
anwide leaf weeds dry weight12 weeks after application (WAA), grass type weeds dry
weight at particular dosages to 4 (WAA) and dry weight of dominant weeds including
Cynodon dactylon, Commelina benghalensis and Centro semapubescens; (2) various
dosages to test caused composition changes of weeds types in observation 2 to 12
(WAA); (3) weeds controlling in various dosages to test did not poison leafs and roots
of unproductive yet oil palm.

Keywords: Metsulfuron methyl, weeds, unproductive yet oil palm.
