Pertumbuhan Tanaman Jagung Manis Akibat Metode dan Bahan Baku Pembuatan Biochar

Abstrak.Pembuatan biochar menjadi cukup dikenal masyarakat Indonesia namun belum dimanfaatkan sebagai sumber unsur hara pertumbuhan tanaman. Penelitian ini bertujuan untuk mengetahui manfaat dua metode pembuatan biochar  dan dua jenis bahan baku dalam menunjang pertumbuhan tanaman jagung manis. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) pola non factorial dengan lima kombinasi dan tiga kali ulangan. Dengan susunan perlakuan yaitu M0 (tanpa biochar), M1 (bambu apus + metode kon-tiki 10 ton ha-1), M2 (bambu apus + metode soil pit 10 ton ha-1), M3 (kayu pulai + metode kon-tiki 10 ton ha-1), dan M4 (kayu pulai + metode soil pit 10 ton ha-1). Hasil penelitian menunjukkan bahwaperlakuan metode pembuatan biochar bambu apus dan kayu pulai berpengaruh nyata terhadap pertumbuhan tanaman jagung manis.Perlakuan M4 (kayu pulai dengan metode Soil Pit) memiliki nilai tertinggi dari semua  parameter  yang dicobakan.Biochar Production Methods and Variuous Feedstocks Influence Corn GrowthAbstract. The making of biochar is well known to the Indonesian people but has not been used as a source of nutrients for plant growth. This study aims to determine the benefits of two methods of making biochar and two types of raw materials in supporting the growth of sweet corn plants. This study used a non-factorial randomized block design (RBD) with five combinations and three replications. With the treatment arrangement, namely M0 (without biochar), M1 (bamboo apus + kon-tiki method 10 ton ha-1), M2 (bambooapus + soil pit method 10 ton ha-1), M3 (pulai wood + kon-tiki method. 10 ton ha-1), and M4 (pulai wood + soil pit method 10 ton ha-1). The results showed that the treatment of the biochar method of apus bamboo and pulai wood had a significant effect on the growth of sweet corn plants. Treatment of M4 (pulai wood with Soil Pit method) had the highest value of all the parameters tested
