Percobaan lapang telah dilakukan di Kebun Percobaan Pekuwon, Bojonegoro, 1992, untuk mcmpelajai sifat-sifat agronomis dan kimiawi tembakau pada berbagai waktu tanam sorgum pada sistem tumpangsai tembakau + sorgum. Percobaan disusun dalam rancangan acak kelompok dengan enam ulangan. Perlakuan terdiri dai 5 taraf waktu tanam sorgum yaitu 4 dan 2 minggu sebelum tanam tembakau, bersamaan dengan waktu tanam tembakau, 2 dan 4 minggu setelah tanam tembakau. Ukuran petak 10.8 m x 12.0 m. dengan 240 tanaman tembakau per petak dan 720 tanaman sorgum per petak. Analisis N, P, K, nikotin, dan gula beturut- turut dengan Kyeldhal, Spektrofotometi, Flamefotometi, Titrasi dengan NaOH dan Luff-Schroll. Hasil percobaan menunjukkan bahwa dengan mempcrcepat waktu tanam sorgum dari 4 minggu setelah tanam tembakau menjadi 4 minggu sebelum tanam tembakau sangat menurunkan pertumbuhan, hasil dan mutu. Scbaliknya perlakuan tersebut meningkat¬ kan kadar N-total, P, dan K, dan hasil sorgum tumpangsai, serta tidak berpengaruh pada kadar nikotin, gula, nisbah/nikotin, dan N/nikotin tembakau. Pada keadaan kering yang dialami oleh percobaan ini walaupun hasil tembakau rendah namun mutu hasil masih dalam kisaran yang baik dan persaingan dikuasai oleh tanaman sorgum.Kata kunci: Nicotiana tabacum, sorgum bicolor, tumpangsai, waktu tanam ABSTRACTAgronomics and chemicals properties of tobacco under different planting dates ofsorghum in tobacco -Horghum intercropping systemThe ield expeiment was conducted at Pekuwon Expeimental Station, Bojonegoro, in 1992, to study the agronomic and chemical propeties of tobacco grown under diferent planting dates of sorghum in tobacco+sorghum intercropping system. The expeiment was arranged in randomized block design, with 6 replications. The treatment consisted of 5 levels of sorghum planting, 2 and 4 weeks ater tobacco planting. Plot size was 10.8 m x 12.0 m, with 240 and 720 plants of tobacco and sorghum respectively. The methods for analyses N, P, K, nicotine and sugar analyses were Kyeldhal, Spectrophotometry, Flame photometry, Titration with NaOH, and Luf-Schroll, respectively. The growth, yield, and quality of tobacco were decreased sharply, but the N, P, K contents of the leaves were increased by accelerating planting date of sorghum from 4 weeks ater to 4 weeks before tobacco planting. The content of nicotine, sugar, sugar/nicotine. N/nicotine of the leaves were not afected by this treatment. In dry condition, although the yield of tobacco was low, but the quality was in good category, and the competition in tobacco ♦ sorghum intercropping system was dominated by sorghum.Key words : Nicotiana tabacum, sorghum bicolor, intercropping, planting date

Effect of KS, AS, and urea Compositions and N-dosages on quality of Besuki cigar tobaccoThe experiment was conducted on loamy soil at Ajung, Jember from June 1999 to March 2000. The objective was to study the effect of Kalk Salpetcr (KS), ammonium sulphates (AS), and urea compositions and N-dosages on quality of Besuki cigar tobacco. The treatment consisted of two factors i.e. fertilizer composition and N dosages. The first factor was 5 levels of fertilizer composition, i.e. KS; KS(50%)+AS (50%); AS; KS(50%)+urea (50%) and uea. The second factor was 3 level of N-dosages, i.e. 60, 90 and 120 kg N/ha. The treatments were arranged in factorially randomized block design with 3 replications. Planting space was double row (100+70) cm x 40 cm wiUi a population of 168 plants per plot. Results showed thai AS or urea as side dressing fertilizer was not significantly different from KS fertilizer on the percentage of warpper (dekblad) and binder (omblad) quality, leaf thickness, and burning capacity. But especially on organolcptic AS or urea as side dressing fertilizer decreased organoleptic quality, i.e. the taste was bitter and irritating, less aromatic, bad smell, ash color changed from white to black, and decreased ash resistance. All of those characteristics were not desirable in cigar factory. Based on organolcptic quality we suggest the following : (I) AS and urea should be used as a starter only not as side dressing fertilizer, (2) KS fertilizer still perform Ihe best result (3) recommended N-dosage was 60 kg N/ha.

Evaluation of hybrid resultedrom crossing ofMadura and oriental tobaccoProductivity and quality of tobacco could be improved by improving genetical traits through crossing Oiental tobacco was used as donor parent due to high number of leaves and aromatic that was able to enhanced the yield and quality of Madura tobacco. The exploits of heterosis in hybrid were expected to short cut the time of research The experiment was conducted in some villages i.e. [«bbek and Klompang Barat (District of Pamekasan). Por-dapor and Guluk-guluk (District of Sumenep) during 1997 season. The treatments consisted of four hybrids and Prancak-95 as the standard variety Hie purpose of the experiment was to find out the potency of hybrids and their improvement compared to Prancak-95. Sliced tobacco yields of all treatments were not different, except Ft Prancak-95x Ismir produced 0.701 Mia. closed to Prancak-95, i.e. 0.703 Mia Genotype x environment interaction affected on grade index, but this hybrid still the best one in Lebbek. K lompang Barat. and Por-dapor. Its standard heterosis was 43% while standard heterosis for crop index was 31.41%.

Pada awalnya tembakau cerutu ditanam di wilayah Jember Utara. Tetapi karena berbagai masalah tembakau cerutu berkembang ke Wilayah Tengah dan Selatan Perkembangan ke wilayah baru belum diikuli oleh penyesuaian tcknologi Akihatnya mutu belum sesuai dengan yang diharapkan. Penelitian tahun 1998 dan 1999 dilakukan di Kabupaten Jember dengan tujuan untuk memperoleh informasi tentang sifat klimatologi, lanah, kcragaan hasil dan mutu, kcragaan teknologi dan prefcrensi pasar Informasi ini akan digunakan sebagai dasar untuk perbaikan-pcrbaikan tcknologi. Penelitian dilakukan dengan metode survei. Daerah pengembangan lembakau cerutu di Jember dibagi liga wilayah, I Hara, Tengah. dan Selatan. sesuai dengan pembagian yang telah disetujui oleh masyarakat pctcmbakauan di Jember. Lima desa contoh diambil untuk mewakili liap wilayah. Penetapan contoh bcrdasar tipe tanah Icrluas dan selanjulnya ditclapkan desa dengan areal tembakau cerutu terluas untuk masing-masing tipe lanah Informasi pasar diperoleh dari wawancara dengan enam eksportir terkemuka Hasil penelitian menunjukkan bahwa semua wilayah menghadapi masalah tanah berat yang sulit diolah, dan kandungan bahan organik, nitrogen dan fosfor tanah yang rendah Makin ke Selatan iklim semakin kering, bentuk lahan semakin datar, semakin linggi ketersediaan air di musim kemarau, kebutuhan pupuk nitrogen makin tinggi, dan peluang mendapatkan tembakau pembalut makin linggi. Harga tembakau wilayah Selatan tetinggi dari ketiga wilayah Untuk mempermudah pengelolaan disarankan agar wilayah dibagi dua yaitu wilayah Utara dan wilayah Tengah bagian Selatan dengan lahan bcrgelombang sebagai penghasil utama tembakau iller dan pembungkus dan wilayah Tengah bagian Selatan dan wilayah Selatan dengan lahan datar dan terscdianya air cukup, sebagai penghasil tembakau pembalut dan pembungkus.Kata kunci: Nicotiana tabacum, lembakau cerutu, karaktcrisasi lahan, evaluasi lahan ABSTRACT Characterization and evaluation of development region of besuki cigar tobaccoIhe beginning of cigar tobacco cultivation was in North Region of Jember Regency But due to several problems, the cultivation of cigar tobacco expanded to the Middle and South Region. In the new area, the technology of cigar tobacco was not yet adapted. So the tobacco quality did not match their expectation The research was conducted in 1998 and 1999 in Jember Regency, to get information about the characteistics of climate and soil, yield and quality performance, technology display, and market preference. This information should be used as basic knowledge to improve technology for besuki cigar tobacco. The research used survey method The tobacco cultivation was divided into three regions. Five villages were taken as sampling to represent for each region. Determining samples were based on the village has largest area of cigar tobacco located in largest area of soil type of each region. Market information was achieved from interview with six expoters. The result of this research showed thai Ihe more region lo Ihe Soudi was earlier planning date, flatter land, higher water available and nitrogen fertilization, and greater opportunity to get wrapper tobacco All region faced soil problems, were soil hardly cultivated, and low of organic matter, N, and P content of soil To make management of cigar tobacco cultivation easier, il was proposed lhai the area of cigar tobacco should be divided into two regions i.e. North Region and Middle Region of Southern part with wavy land for tobacco produce iller and binder tobacco, and Middle of Nothern part and South one for tobacco produce wrapper binder tobacco.Key words : Nicotiana tabacum, cigar tobacco, land characterization, land evaluation
