title: Uji Lanjutan Fitotoksisitas dan Efikasi Herbisida Aminosiklopiraklor pada Kelapa Sawit (Elaeis guineensis Jacq.) Belum Menghasilkan creator: Anissa Indra Wati, 1014121073 subject: description: Penelitian dilakukan untuk mengetahui gejala keracunan herbisida aminosiklopiraklor, tingkat keparahan keracunan herbisida aminosiklopiraklor pada beberapa taraf dosis herbisida, pengaruh herbisida aminosiklopiraklor terhadap pertumbuhan tanaman, dan efektivitas herbisida aminosiklopiraklor dalam mengendalikan gulma pada piringan kelapa sawit. Penelitian dilaksanakan di Kelurahan Rajabasa, Bandar Lampung dan Laboratorium Ilmu Tanaman Fakultas Pertanian Universitas Lampung pada bulan Oktober 2013 – Januari 2014. Penelitian disusun dalam Rancangan Kelompok Teracak Sempurna dengan 9 perlakuan dan 4 ulangan. Susunan perlakuan: aminosiklopiraklor 7,5; 15; 30; 60 g ha-1, glifosat 729 g ha-1, aminopiralid + triklopir 115,2+64,8 g ha-1, 2,4-D 1297 g ha-1, pengendalian mekanis, dan kontrol. Homogenitas ragam diuji dengan uji Bartlet, aditivitas diuji dengan uji Tukey, dan perbedaan nilai tengah diuji dengan uji Beda Nyata Terkecil taraf 5%. Hasil penelitian: (1) aminosiklopiraklor 15 – 60 g ha-1 menyebabkan gejala keracunan tanaman kelapa sawit belum menghasilkan dari 2 – 10 MSA; (2) aminosiklopiraklor 60 g ha-1 menyebabkan tingkat keracunan tertinggi dibandingkan aminosiklopiraklor 7,5 – 30 g ha-1, setara dengan ketiga herbisida pembanding; (3) herbisida aminosiklopiraklor dan herbisida pembanding menyebabkan pelepah daun tanaman teracuni, menurunkan tingkat hijau pelepah daun tetapi tidak menekan penambahan tinggi tanaman; (4) aminosiklopiraklor 15 – 60 g ha-1 menekan panjang pelepah daun setara dengan aminopiralid+triklopir 115,2+64,8 g ha-1 dan 2,4-D 1297 g ha-1. Aminosiklopiraklor 60 g ha-1 menghambat pertumbuhan akar tanaman; (5) herbisida aminosiklopiraklor tidak menekan bobot kering gulma total, tetapi aminosiklopiraklor 30 dan 60 g ha-1 menekan persentase penutupan gulma total pada 4, 8, dan 10 MSA. Aminosiklopiraklor 60 g ha-1 mengendalikan Asystasia gangetica pada 2, 4, dan 8 MSA. Kata kunci: aminosiklopiraklor, efikasi, fitotoksisitas, kelapa sawit belum menghasilkan This research was tested to determine aminocyclopyrachlor herbicide poisoning symptoms, the severity of toxicity of aminocyclopyrachlor herbicide in immature oil palm as affected by different doses of herbicide, the effect of aminocyclopyrachlor herbicides on the plant growth, and the effectiveness of aminocyclopyrachlor herbicide in controlling weeds in immature oil palm. The research was conducted from October 2013 – January 2014 in Rajabasa Village, Bandar Lampung and Plant Science Laboratory, Faculty of Agriculture, University of Lampung. The research was arranged in Randomized Completely Block Design with 9 treatments and 4 replications. The treatments: 7,5; 15; 30; 60 g ha-1 aminocyclopyrachlor, 729 g ha-1 glyphosate, 115,2 + 64,8 g ha-1 aminopyralid + trichlopyr, 1297 g ha-1 2,4-D, mechanical control, and control. The homogeneity of variance was tested by Bartlett’s test, additive was tested by Tukey's test, and differences in the value being tested with Least Significant Difference test at 5% level. The results: (1) aminocyclopyrachlor 15 – 60 g ha-1 cause poisoning symptom on immature oil palm from 2 – 10 Weeks After Application; (2) aminocyclopyrachlor 60 g ha-1 cause the highest level of toxicity compared to aminocyclopyrachlor 7,5 – 30 g ha-1, but is equivalent with three others comparator herbicides; (3) aminocyclopyrachlor and three others comparator herbicides cause poisoning symptom in leaf midrib, decrease the levels of green leaf midrib but not suppress the addition of plant height; (4) aminocyclopyrachlor 15 – 60 g ha-1 suppress the leaf midrib length equivalent to aminopiralid + trichlopyr 115,2 + 64,8 g ha-1, and 2,4-D 1297 g ha-1. Aminocyclopyrachlor 60 g ha-1 inhibit root growth of plant; (5) aminocyclopyrachlor herbicide cannot suppress the total dry weight of weeds, but aminocyclopyrachlor 30 and 60 g ha-1 suppress the percentage of the total weeds cover at 4, 8, and 10 WAA. Aminocyclopyrachlor 60 g ha-1 controls the Asystasia gangetica at 2, 4, and 8 WAA.
