      Abstract
      Kehadiran gulma memberikan dampak negatif. Pengendalian gulma yang tepat ditentukan atas dasar dominansi gulma dan kuantitasnya pada lahan perkebunan kelapa sawit. Penelitian yang dilakukan bertujuan untuk mengetahui adakah interaksi keragaman gulma pada beberapa kondisi lahan diberbagai kedalaman dan menguji efikasi herbisida. Analisis vegetasi dan seed bank yang dilakukan di daerah dengan ketinggian lahan yang berbeda. Ketinggian lahan yang diuji yaitu diketinggian 8 mdpl (genangan), ketinggian 12 mdpl (normal) dan ketinggian 21 mdpl (terasan). Kedalaman tanah yang diuji 0-10 cm, 10-20 cm dan 20-30 cm. Herbisida yang digunakan yaitu Glifosat merek A dan merek B. Hasil penelitian menunjukkan bahwa berdasarkan uji statistik terdapat interaksi antara ketiga kondisi lahan dengan ketiga kedalaman tanah. Aplikasi herbisida merek A dan merek B tidak beda nyata terhadap penurunan bobot gulma. Secara umum herbisida merek B memberikan pengaruh penurunan bobot gulma yang diinginkan lebih baik, sedangkan herbisida merek A memberikan pengaruh lebih baik dalam penurunan bobot gulma yang dapat diterima dan tidak diinginkan.
       
      Weeds have a negative impact on crop. Appropriate weed control is determined on the base of weed dominance and quantity in oil palm plantations. The research conducted aims to determine whether there is an interaction of weed diversity in several land conditions at various depths and test the efficacy of herbicides. Vegetation and seed bank analysis were conducted in areas with different land elevations. The land elevation tested was at 8 masl (inundation), 12 masl (normal) and 21 masl (terrace). Soil depth tested was 0-10 cm, 10-20 cm and 20-30 cm. Herbicides used were glyphosate brand A and brand B. The results showed that based on statistical tests there was an interaction between the three land conditions with the three soil depths. The application of brand A and brand B herbicides had a not significant difference on weed weight reduction. In general, brand B herbicides have a better effect on reducing the weight of desirable weeds, while brand A herbicides have a better effect on reducing the weight of acceptable and undesirable weeds.
