The purpose of this analysis was to determine the independent variables which most affected the dependent ones as crops index and leaf nicotine contain, so that it could reduce the number of independent variables. The agronomical characteristics consist of leaf number/plant, seventh and fiteenth leaf area, dried slice leaf/ha, grade index and crop index obtained from fetilizer experiment on three Virginia tobacco lines at Pekuwon Experimental Garden Bojonegoro, from May to October 2002.

Beberapa musuh alami juga telah ditemukan, terutama semut yang bcrfungsi sebagai predator bagi Helopeltis spp. Akhir-akhir ini ketiga jenis serangga tersebut sering bcrada bersamaan dalam satu tanaman. Oleh sebab itu penelitian ini bertujuan untuk mengetahui pcranan semut dan intcraksinya dengan Helopeltis spp. dan S. indecora. Penelitian dilaksanakan di Dusun Sambik Rindang dan Sambik Jengkel, Lombok Barat dai bulan Mei sampai dengan Nopember 2003 Penelitian tcrdiri atas 3 kegiatan yang satu sama lain saling menunjang, yaitu (a) penelitian lapang, (b) penelitian semi lapang, dan (c) penelitian rumah kaca/pot. Pada penelitian lapang keadaan lingkungan tidak dikendalikan. pengamatan dilakukan dengan penarikan contoh. Penelitian lapang ditunjang oleh penelitian semi lapang, yaitu hanya salah satu faktor lingkungan yang dikendalikan (faktor populasi semut : 0, 5, dan 10 koloni per 5 tanaman). Penelitian semi lapang kemudian ditunjang oleh penelitian rumah kaca/pot. Pada penelitian ini tiga faktor dikendalikan/diperlakukan yaitu populasi semut, populasi Helopeltis dan populasi Sanurus indecora. Hasil pengamatan menunjukkan bahwa hama utama yang dominan di Dusun Sambik Jengkel berbeda dengan hama utama yang dominan di Dusun Sambik Rindang. Di Sambik Jengkel, Helopeltis lebih dominan dibandingkan dengan i'. indecora, walaupun S. indecora ditemukan tapi tidak sebanyak serangan Helopeltis. Di Sambik Rindang terjadi sebaliknya, 5. indecora lebih dominan bila dibandingkan dengan Helopeltis. Semut cukup berperan dalam mengendalikan populasi Helopeltis.

Tidak demikian yang terjadi dengan ,S'. Indecora, populasi nimfa dan imagonya tidak dipengaruhi oleh kehadiran semut. Pada kelompok tanaman yang dibei perlakuan semut, populasi S. indecora justru lebih banyak. Namun demikian, jumlah bunga yang diserang S. indecora lebih banyak pada pucuk yang tidak ada semutnya.

The treatment consisted of two factors, i.e. basal dressing (NPK compound fetilizer and SP36 + urea) and side dressing (urea, CN, CN + CPN, CN + PN, and CSN). The treatments were arranged in a factoially randomized block design with 3 replications. Planting space was double row (110 cm + 90cm) x 35 cm, 200 plants per plot. Tobacco vaiety was H382. The results of the experiment showed that the effect of NPK fetilizer was not s","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":"77871485","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}

The data were analyzed using multiple linear regression and two stage least square (2 SLS) estimation method. The result of analysis revealed that the factors affecting pepper supply from Indonesia were international market, world price, pepper production, exchange rate, and the last export volume. The supply export of pepper of each major pepper producing counlircs showed similar characeristics, i.e. die expot of pepper of the countries, including Indonesia was affeclcd signiicantly by the national pepper production. When the price changed, the supply would change with the percentage higher than that of the price change. The demand for pepper import at the elasticity coeicient value smaller than one (0.144 -0.680) meant that it was inelastic. The elasticity coeficient value of the Indonesian pepper supply in the short and long terms was 1 168 and 4.037 respectively. It meant that they were elastic, if the price changed, the supply would change with the percentage higher than thai of the price change. The implication to Ihe pepper industry in Indonesia were (a) the decrease in Ihe pepper price in the international market did not affect the national pepper production, and (b) the exchange rale affect the volume of the pepper export.","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":"74932358","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}
