This studyaimed to determine the influence of giving Sinabung volcanic ash about dendang
rice plant variety growth and production on the peat soil. This study used anon-factorial
randomized block designwithtreatmentV0(without volcanic ash), V1 (250 g/10 kg wet peat),
V2 (500 g/10 kg wet peat), V3 (750 g/10 kg wet peat), V4 (1000 g/10 kg wet peat), V5 (1250
g/10 kg wet peat), V6 (1500 g/10 kg wet peat) withthreereplications. The result showedthat
thegiving of Sinabung volcanic ash obviously able to increase pH, Electrical Conductivity,
Cation Exchange Capacity, Exchangeable Cations (Na, K, Ca, Mg), and P-available on
the peat soil and obvious influential about the plant growth and production.
Penelitian ini bertujuan untuk mengetahui pengaruh dari pemberian debu vulkanik Sinabung terhadap pertumbuhan dan produksi tanaman padi varietas dendang pada tanah gambut. Penelitian ini menggunakan Rancangan Acak Kelompok non faktorial dengan perlakuan V0 (tanpa debu vulkanik), V1 (250 g/10 kg Gambut Basah), V2 (500 g/10 kg gambut basah), V3 (750 g/10 kg gambut basah), V4 (1000 g/10 kg gambut basah), V5 (1250 g/10 kg gambut basah), V6 (1500 g/10 kg gambut basah) dengan 3 ulangan. Hasil penelitian menunjukkan bahwa pemberian debu vulkanik Sinabung secara nyata mampu meningkatkan kemasaman tanah (menurunkan pH), DHL, KTK, Basa-basa Tukar (Na, K, Ca, Mg), P-tersedia pada tanah gambut dan juga meningkatkan pertumbuhan dan produksi tanaman.
