Penelitian ini bertujuan untuk mengetahui pengaruh debu vulkanik gunung Sinabung dan pupuk kompos jerami padi terhadap pertumbuhan tembakau Deli. Penelitian ini dilaksanakan di Balai Penelitian Tembakau Deli (BPTD) Sampali, Kecamatan Percut Sei Tuan, Kabupaten Deli Serdang, Provinsi Sumatera Utara pada ketinggian tempat + 15 meter diatas permukaan laut. Penelitian ini dilaksanakan pada bulan Mei sampai dengan Juli 2015. Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Kelompok Non Faktorial yang terdiri dari 6 perlakuan top soil: debu vulkanik : kompos jerami padi yaitu: M0 (15 kg: 0 kg: 0 kg), M1 (13 kg: 2 kg: 0 kg), M2 (13 kg: 1.5 kg: 0.5 kg), M3 (13 kg: 1 kg: 1 kg), M4 (13 kg: 0.5 kg: 1.5 kg), M5 (13 kg: 0 kg: 2 kg). Hasil penelitian menunjukkan bahwa perbandingan debu vulkanik dengan pupuk kompos jerami padi berpengaruh nyata terhadap diameter batang pada 18 hari setelah pindah tanam (HSPT) – 46 HSPT dan jumlah daun per tanaman pada umur 46 hari setelah pindah tanam (HSPT). Perbandingan debu vulkanik dan kompos jerami padi tidak berpengaruh nyata terhadap tinggi tanaman, panjang daun pasir (Z), panjang daun kaki I (VA), lebar daun pasir (Z), lebar daun kaki I (VA), berat segar daun pasir (Z) dan berat segar daun kaki I (VA).
The purpose of the study was to determine the effect of planting media top soil, Sinabung volcanic ash and straw compost on the growth of Deli tobacco. The research was conducted at Balai Penelitian Tembakau Deli (BPTD) Sampali, Sub District Percut Sei Tuan, District Deli Serdang, Province North Sumatera with the height of + 15 metres above sea level, began from Mei until July 2015. The research was arranged with a non-factorial randomized block design which is consisting of 6 treatments ratio of top soil : volcanic ash : straw compost that is M0 (15 kg: 0 kg: 0 kg), M1 (13 kg: 2 kg: 0 kg), M2 (13 kg: 1.5 kg: 0.5 kg), M3 (13 kg: 1 kg: 1 kg), M4 (13 kg: 0.5 kg: 1.5 kg), M5 (13 kg: 0 kg: 2 kg). The result showed that volcanic ash and straw compost significantly affected to stem diameter at 18-46 days after planting and number of leaf at 46 days after transplanting. Volcanic ash and straw compost did not significantly affected to plant height, sand leaf length (Z), feet leaf I length (VA), sand leaf width (Z), feet leaf I width (VA), fresh weight of sand leaf (Z) and fresh weight of feet leaf I (ZA).
