RINGKASAN
Tujuan penelitian ini adalah apakah ada Pengaruh jarak tanam dan tinggi pangkasan Terhadap kuantitas dan kualitas produksi. Dalam percobaan ini varietas tembakau yang digunakan adalah varietas Kasturi GG, yang diperoleh dari Dinas Perkebunan Kabupaten Dati II Jember. Percobaan dilakukan di Dusun Brumbun, Desa Lamongrejo, Kecamatan Alqimbang, Kabupaten Lamongan. Jenis tanah asosiasi regosol klabu dan latosol coklat, pH tanah netral (6,3). Rata-rata curah hujan selama berlangsungnya percobaan adalah 107 mm/bulan dan rata-rata hari hujan 8,3 hari. Percobaan dilaksanakan pada akhir april 2017 sampai dengan Oktober 2017. Penelitian ini menggunakan rancangan acak kelompok faktorial dengan dua faktor yaitu jarak tanam dan tinggi pangkasan. Faktor jarak tanam terdiri dari tiga tingkat, yaitu J1 (Jarak tanam 90 x 40 cm), J2 (Jarak tanam 90 x 50 cm), J3 (Jarak tanam 90 x 60 cm). Sedangkan pemangkasan dari 4 tingkat F1 Â (hanya karangan bunga yang dipangkas), F2 (karangan bunga + dua daun dibawahnya dipangkas), F3 (karangan bunga + empat daun dibawahnya dipangkas), F4 (karangan bunga + enam daun dibawahnya dipangkas). Hasil percobaan menunjukkan bahwa kecuali dalam hal warna krosok, baik jarak tanam maupun tinggi pangkasan berpengaruh sangat nyata terhadap kuantitas dan kualitas produksi. Kecuali dalam hal tebal daun dan warna krosok, pada umumnya terdapat interaksi yang sangat nyata antara jarak tanam dan tinggi pangkasan.
