Abstract

Gulma yang tumbuh ke permukaan tanah berasal dari simpanan biji gulma di dalam tanah. Terdapat banyak propagul gulma yang tersimpan di dalam tanah sawah. Penelitian ini bertujuan untuk mengidentifikasi propagul gulma pada berbagai jenis tanah sawah. Penelitian dilakukan sejak Februari hingga Mei 2019 di rumah kaca Fakultas Pertanian Universitas PGRI Yogyakarta. Percobaan disusun dalam rancangan acak lengkap (RAL) faktorial dan diulang tiga kali. Faktor pertama adalah jenis tanah sawah terdiri atas empat macam, yaitu: tanah pasir pantai, vulkanik, latosol, dan regosol. Faktor kedua adalah kedalaman tanah terdiri atas enam aras, yaitu: 0-5, >5-10, >10-15, > 15-20, >20-25, dan >25-30 cm. Hasil penelitian menunjukkan bahwa jumlah jenis gulma tertinggi pada tanah regosol, kemudian menurun pada tanah pasir pantai dan terendah pada tanah vulkanik dan latosol. Jumlah propagul gulma tertinggi terdapat pada tanah regosol di kedalaman >10-15 cm. Temuan penelitian menunjukkan bahwa ada perbedaan nyata jumlah propagul gulma antar jenis tanah maupun antar kedalaman tanah sawah. Kami menyarankan bahwa untuk pengendalian gulma agar berhasil maksimal, maka perlu disesuaikan dengan jenis tanah sawah untuk budidaya padi.
