Penelitian ini bertujuan untuk mengidentifikasi jenis gulma yang ditemukan pada umur tanaman karet yang berbeda serta menentukan faktor apa saja yang mempengaruhinya. Penelitian dilaksanakan di Desa Pageralang Kecamatan Kemranjen yang dimulai dari tanggal 15 September hingga 28 September 2019. Penelitian ini menggunakan metode survei dengan teknik petak kuadrat, penentuan lokasi penelitian dilakukan secara purposive sampling berdasarkan keberadaan gulma di lapangan. Pengambilan sampel dilakukan pada 4 lahan yang memiliki umur berbeda dengan menggunakan plot berukuran 100x100cm. Hasil penelitian menunjukkan bahwa Keragaman vegetasi gulma yang tumbuh sebanyak 17 jenis gulma dan Gulma dominan yang ditemukan ialah pada kelompok umur muda (5 tahun) : Ageratum conyzoides, kelompok umur remaja (6 tahun) : Cyperus kyllingia, kelompok umur tanaman (11 tahun) : Cyperus kyllingia, kelompok dewasa (13 tahun) : Ottochloa nodosa. Faktor yang mempengaruhi variabilitas gulma adalah faktor internal dan eksternal. Faktor internal meliputi cara gulma berkembang biak, sedangkan faktor eksternal meliputi umur tanaman, cahaya matahari, suhu, kelembaban tanah, letak kebun dan pengolahan lahan.
Kata kunci: gulma, karet, variabilitas, vegetasi.
