The experiment was designed as a completely randomized, arranged factorially in three replications. The pepper variety used for the experiment was Lampung Daun Lebar. The disc distance of pepper decorticator in this experiment was set at 3.5 cm based on the preliminary experiment. Results showed that the optimal disc diameter and nibber elasticity was 20 cm and 7.74 N/mm respectively. Decorticator performance on the optimal condition were : decorticated pepper 97.25%, white pepper damage as pepper defect 2.46% and as broken pepper 1.98% respectively and the capacity of decorticator was 42.27 kg/hours.

Perlakuan disusun secara faktorial dalam rancangan petak terbagi dengan tiga ulangan Perlakuan petak utama terdiri atas macam klon rami. yaitu Pujon 10 dan Jawa Timur, sedangkan anak petak berupa pembeian ZPT, PPC. dan ZPT ' PPC tcrdii atas scmbilan macam yang meliputi : (1) 60 N + 20 P,Oj * 60 KjO ' 10 ton pupuk kandang sapi, (2) 60 N • 20 P20, • 60 KjO - 10 ton pupuk kandang sapi • ZPT 1 (kons 1 ml/1), (3) 60 N • 20 PjO, + 60 K20 > 10 ton pupuk kandang sapi • ZPT 2 (0 5 ml/I); (4) 60 N * 20 P20, ♦ 60 KjO ♦ 10 ton pupuk kandang sapi * PPC 1 (3 g/l); (5) 60 N • 20 P20, - 60 K20 t 10 ton pupuk kandang sapi • PPC 2 (0.65 gl); (6) 60 N < 20 P205 + 60 K20 + 10 ton pupuk kandang sapi ♦ ZPT 1 + PPC I, (7) 60 N + 20 P2Os + 60 K20 r 10 ton pupuk kandang sapi t ZPT1 + PPC 2, (8) 60 N - 20 P2O5 * 60 KjO 1 10 ion pupuk kandang sapi + ZPT 2 + PPC 1 dan, (9) 60 N + 20 P2Oj + 60 K20 t 10 ton pupuk kandang sapi + ZPT 2 l- PPC 2. Ukuran petak 3 6 m x 6 m, jarak tanam 60 cm x 40 cm. Hap lubang ditanam satu stck rhi/.om panjang 8 cm Hasil percobaan menunjukkan bahwa pembeian ZPT 1 * PPC 2 dan ZPT 2 * PPC 2 dengan pemupukan NPK melalui lanah dapat meningkatkan pertumbuhan vegetatif dan hasil serat dibanding dengan pemupukan melalui tanah saja. Peningkatan hasil serat panen II • III masing-masing mencapai 58% (dari 565 2 kg/ha tanpa ZPT - PPC menjadi 895.0 kg/ha) dan 61% (dai 565.2 kg/ha tanpa ZPT + PPC menjadi 908.5 kg/ha). Potensi hasil klon Pujon 10 lebih besar dibandingkan dengan klon Jawa Timur.Kata kunci : Boehmeria nivea, ZPT, PPC, pupuk kandang ABSTRACT Effect of growth regulators and liquid fertilizers on the growth and yield of ramie in WonosoboCrop removal of ramie plant it very high because it is harvested every 60 days A ield experiment was carried out at Sedayu, Sapuran, Wonosobo since April 2001. Ihe type of soil and climate was brown latosol and Bl respectively. The objective of the expeiment was to study effect of plant regulators, liquid fertilizers (PPC), and its combinations on accelarating vegetative growth on two clones of ramie. The experiment was arranged in split plot design with three replicatins The main plots were two clones of ramie (Pujon 10 and Jawa Timur) and the sub plots were nine treatments consist of plant regulators, liquid fertilizer, and its combination were tried as sub treatment (I) 60 N > 20 P2Oj » 60 K20 + 10 tons manure of cow waste; (2) 60 N * 20 P2Os * 60 K20 I 10 tons manure of cow + ZPT I (kons I ml/1); (3) 60 N « 20 P2Os • ","PeriodicalId":17774,"journal":{"name":"Jurnal Penelitian Tanaman Industri","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89017711","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lincat is a disease caused by a complexinvasion of three pathogens i.e. Meloidogyne spp. (root-knot nematode),Ralstonia solanacearum (bacteria) and Phytophthora nicotianae (fungus).Hybridization between variety Sindoro 1 (moderately resistant to R.solanacearum but susceptible to Meloidogyne spp. and highly susceptibleto P. nicotianae) and virginia tobacco (resistant to these three pathogens)has resulted in six lines. These lines were planted in three locations for 3years and were evaluated for their yield, grade index, crop index, andresistance intensity to these three pathogens, using randomized blockdesign with 3 replications. Two promising lines were resulted from thisevaluation i.e. (1) Line A, that has productivity of tobacco sliced : 0.880ton per hectare, grade index: 40.28 crop index: 35.47 and nicotine content:5.52%.
