Abstract
Weed control in the immature phase of oil palm cultivation is very
important to ensure optimal growth in the future. This study aims to evaluate
the effectiveness of 150 g/L ammonium glufosinate herbicide in controlling
weeds in immature oil palm plantations and its impact on the main crop. The
study was conducted in Garut, West Java, using a Randomized Block Design (RBD)
with seven treatments and four replicates. The treatments consisted of five
levels of ammonium glufosinate dosage (1.5, 2.0, 2.5, 3.0, and 3.5 L/ha),
manual weeding, and control. The parameters observed included vegetation
analysis (SDR), dry weight of weeds at 4, 8, and 12 WAA, and symptoms of
phytotoxicity in oil palm plants. The results showed that the application of
ammonium glufosinate at a dose of 1.5–3.5 L/ha was effective in controlling
total weeds, dominant broadleaf weeds (Stachytarpheta jamaicensis) and
grass weeds (Digitaria sanguinalis) for up to 12 WAA. A dose of 2.5 L/ha
was identified as the most optimal dose in suppressing total dry weight of
weeds and providing efficacy equivalent to or better than manual weeding. All
herbicide doses tested did not cause phytotoxicity symptoms on the stems,
leaves, or fronds of oil palms, making them safe for use in the immature phase.
In conclusion, ammonium glufosinate 150 g/L herbicide is an effective and
efficient alternative for weed control without damaging the main crop.
