Tujuan penelitian adalah untuk mendapatkan nomor harapan jambu mente (Anacardium occidentale I..) yang toleran terhadap cekaman air, khususnya pada fase pembibitan Percobaan dilaksanakan di rumah kaca Balai Penelitian Bioteknologi Tanaman Pangan dan Laboratorium Balai Penelitian Tanaman Rempah dan Obat, dari bulan Mei-Agustus 2001. Rancangan faktorial dengan dua faktor dan tiga ulangan disusun dalam rancangan acak kelompok. Faktor pertama adalah empat nomor harapan jambu mente yaitu : F2-8, III 4/2, P 293 dan B 02, dan sebagai faktor kedua adalah enam tingkat cekaman air yaitu : 50%, 55%, 60%, 65% 70% dan 75% kapasitas lapang (KL) Parameter yang diamati meliputi: pertumbuhan bibit (tinggi, jumlah daun, luas daun), bobot kering bibit (batang, daun dan akar), seta analisis kandungan prolin bebas. Hasil percobaan menunjukkan bahwa intcraksi nomor harapan dengan perlakuan cekaman air berbeda nyata terhadap kandungan prolin bebas. Kandungan prolin bebas tertinggi terdapat pada nomor B 0-2 pada cekaman air 50% KL, tetapi tidak berbeda nyata dengan F2-8, sedangkan kandungan prolin terendah didapatkan pada nomor III 4/2 dengan cekaman air 75% KL. Faktor tunggal nomor harapan berbeda nyata terhadap pertumbuhan bibit dan bobot keing bibit jambu mente. Dari empat nomor harapan yang diuji didapatkan bahwa nomor F2-8 mempunyai pertumbuhan bibit (tinggi, jumlah daun) dan bobot keing bibit yang paling tinggi dibandingkan nomor lainnya, sedangkan nomor B 0-2 mempunyai petumbuhan bibit (tinggi dan jumlah daun) dan bobot keing bibit yang paling rendah. Faktor tunggal tingkat cekaman air berbeda nyata terhadap pertumbuhan dan bobot keing bibit. Dai enam tingkat cekaman air didapatkan bahwa sampai cekaman air 70% KL pertumbuhan bibit (tinggi, jumlah daun, luas daun) tidak berbeda nyata, akan tetapi pada cekaman air 65% KL pertumbuhan dan bobot keing bibil berbeda nyata Berdasarkan petumbuhan bibit dan kandungan prolin bebas, dapat dikemukakan bahwa nomor F2-8. lebih toleran terhadap cekaman air dibandingkan dengan nomor lainnya.Kata kunci: Anacardium occidentale L, cekaman air, petumbuhan, fase bibit ABSTRACT Effect of water stress on the growth offour cashew line seedlings Water shortage during the seedling growth stage cashew is one of the limiting factors.

Hasil jagung pada tahun petama tanpa kenaf dan satu kali tanam kenaf sebelum jagung, masing-masing sebesar 3.70 dan 4 47 ton/ha.Kata kunci: Kenaf, rotasi tanaman, padi, jagung, irigasi, kesuburan tanah ABSTRACTEffect of kenaf rotation on paddy and corn yieldThe fetility status of soil could be improved through the application of organic matter, fresh green plant or crop rotation practices. An experiment on kenaf-paddy-com rotalion was conducted ai Canggu Village, Pare Sub District, Kediri District from 1992/1993 to 1994/1995 on grey brown regosol. The altitude was 70 m above sea level, and the climate type was C3 according to Oldeman classiication. The purpose of the study was to know the effect of kenaf rotation on paddy and com yields and some soil characteristic change ater kenaf planting in irrigalcd land. The cxperimenl was arranged in a randomized block design with three replications. All treatments consisted of 12 kinds of rotations. Plot size was 14 m x 10 m. The variety of paddy, com, and kenaf used in this experiment were IR-64, CPI and He G4 respectively. The plant spacing were 20 cm x 20 cm; 75 cm x 30 cm and 20 cm x 15 cm respectively. The result indicated that the frequency of growing kenaf enhanced C- organic, Total-N and CEC status. Paddy yield in the irst year of growing none, once and two times of kenaf before paddy obtained 5.19; 5.25 and 6.24 ton/ha respectively. Paddy yield in the irst ","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":"83896195","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}

Rancangan yang digunakan adalah rancangan acak kelompok dengan tiga ulangan. Perlakuan tcrdiri dari 12 galur harapan yaitu SI.14, SI.16, SI.18, SI 20, SI.21, SI.24, SI.25, SI.26, S1.28, SI.31, SI.13, SI.40, dan sebagai pembanding digunakan 2 varietas komersial yaitu Sumberrejo 1 dan Sumberrejo 2. Hasil penelitian menunjukkan bahwa terdapat 4 galur unggul yaitu galur SI.14, SI.16, SI.18, SI.24 potensi hasil sama dengan varietas Sbr. I mempunyai adaptasi luas (galur stabil). Empat galur lainnya dapat bcrproduksi tinggi apabila ditanam pada kondisi lingkungan sesuai (spesifik lokasi). Galur SI. 21 dan SI 25 sesuai untuk daerah Nganjuk dan Sragen, galur SI 20 untuk daerah Bojonegoro dan Nganjuk, dan SI 28 untuk daerah Lumajang.Kata kunci : Wijen, Sesamum indicum L., galur, hasil, spesifik lokasi ABSTRACT Yield Stabibity of Sesame LinesThe experiment was conducted at four locations of sesame development area, viz. Lumajang, Bojonegoro, Nganjuk and Sragen districts, in 2003 planting seasons. The aim of this experiment was to find out the sesame lines having high productictivity and suitable for the development areas. Twelve promising lines, namely SI.14, SI.16, SI.18, SI.20, SI.21, SI.24, SI.25, SI.26, SI.28, SI.3I, SI.13, SI.40, and two control varieties (Sumberrejo 1 and Sumbenejo 2) were evaluated in randomized block design with three replications. The result of this experimental found out 4 superior lines (SI 14, SI 16, SI 18, and SI 24) that have the same potential as Sbr I variety, gave broad adaption to all locations (stable lines). Nevertheless the other four lines evaluated showed as the specific location lines. Those lines arc SI 21 and SI 25 that are appropriate for nganjuk and Sragen; SI 20 that is appropriate for Bojonegoro and Nganjuk, and SI 28 that is appropriate for Lumajang.Key words : Sesame, Sesamum indicum L., line, yield, specific location","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":"85263928","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}
