Efikasi Herbisida Metil Metsulfuron Terhadap Gulma pada Pertanaman Kelapa Sawit (Elaesis guinensis Jacq.) yang Belum Menghasilkan (TBM)
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-1metsulfuron 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.
