Abstract

ABSTRACTThe role of nitrogen in the process of photosynthesis is very important. It affects the growth, development and yield, especially leaves. Lemon grass produces citronella oil that contained in the leaves. One of the efforts to increase leaves yield is by application of N fertilizer. The aims of this research were to obtain optimal N dosage to improve herbage yield and quality of lemon grass. The research was conducted in Manoko Research Station, Lembang West Java from April - December2014. Using randomized block design, with 4 replicates and 6 treatments. The treatments consisted of 0; 2,3; 4,6; 6,9; 9,2 and 11,5 g N/plant. Lemon grass used from G3 accession. Parameters observed included plant growth (height and number of tillers), yield (fresh and dry herbs weight, and oil yield), and quality (yield, oil and citronella content). The results showed that N application significantly increased the growth, yield, and quality of lemon grass. Application of 4,6 g N/plant of N was optimum dosage for plant height and tiller number, total yield of herbage fresh weight (2904.46 g/plant) and leaves dry weight (1574.83 g/plant), yield (1.55%), oil content (2.06%), citronella content (41.59%). The best yield of citronella was obtained from aplplication of 6,9 g N/plant.Keywords: Cymbopogon nardus L., nitrogen, yield, citronella content PENINGKATAN PRODUKSI HERBA DAN MUTU SERAI WANGI DENGAN PENAMBAHAN NITROGENABSTRAKPeranan nitrogen dalam proses fotosintesis sangat penting antara lain berpengaruh terhadap pertumbuhan, perkembangan dan produksi daun tanaman.

Its rhizome has efficacy to curevarious diseases such as disorder on lever, gall bladder and pancreas.There is a tendency that people want to use therapy by natural materials,increases demand of turmeric seed as raw material of medicine industry inIndonesia. This condition provides a chance to farmers as supplier of plantmaterials. However, up to now, the high need of plant materials causes thelimitation of supply so that their alternatives are needed for providing plantmaterials in maximum number. The part of plant material provision in highnumber and in a short time and free from pests and diseases can beconducted through tissue culture technique. However, this technique islimited by the high cost of multiplication, among others the use ofchemical materials. Therefore, the use of growth regulator originated fromnatural material as substitution of synthetic growth regulator need to beassessed, one of them is coconut water. The experiment was carried out atthe laboratory of Tissue Culture, Germ Plasm, and Plant Breeding,Indonesia for Medicinal and Aromatic Crop Research Institute, Bogorfrom May to December 2009. Explants originated from sterile turmericshoots, product of previous multiplication. Media used was Murashige andSkoog (MS) combined with several concentration levels of coconut water( 0; 5; 10; 15, and 20%) as substitution of growth regulator and coconutwater by using millipore. Solid media was used, as comparison on mediaof chemical MS + was BA1.5 mg/l. The experiment was arranged incompletely randomized design with 10 replications. Parameters observedwere the numbers of shoots, leaves and roots. Results showed that withoutchemical component, by addition of coconut water on variousconcentrations on based media of MS, produced shoots, leaves and roots.The highest shoot number obtained on combination of media and additionof coconut water 15% as many as 3.4 shoots, with the number of leaves2.2 leaves at the age of 2 weeks and the highest roots formed on 15 %coconut water as many as 13.2 roots. Whereas on combination of mediawith millipore, the highest shoots were only 2.6 shoots, however it was notsignificantly different from treatment of control MS + BA 1.5 mg/l, itproduced 2.6 shoots,3.6 leaves and 15.4 roots.Key words : Curcuma xanthorrhiza Roxb., in vitro, coconut water,growth regulator, multiplication in vitro

Abstract

ABSTRAKRekomendasi cara pengendalian hama pengisap daun, Amrascabiguttula (ISHIDA) pada  tanaman  kapas masih  mengandalkanpenggunaan kombinasi varietas tahan dan perlakuan benih denganinsektisida kimia sistemik imidakloprid. Namun, tidak jarang petanimelakukan penyemprotan insektisida kimia pada kanopi tanaman yangjuga dapat membunuh serangga berguna, termasuk musuh alami. Tujuanpenelitian adalah untuk mengetahui keefektifan teknik pengendalian A.biguttula pada kapas menggunakan varietas dan insektisida. Penelitiandilakukan di KP Asembagus mulai Januari sampai dengan Nopember2010. Perlakuan petak utama, yaitu teknik pengendalian: (1) perlakuanbenih dengan imidakloprid (PB), (2) tanpa perlakuan benih maupunpenyemprotan kanopi tanaman atau kontrol (TPB), (3) perlakuan benih +penyemprotan kanopi (PBS), dan (4) penyemprotan kanopi (S). Perlakuananak petak adalah tiga galur/varietas kapas, yaitu: (1) galur 98050/9/2/4,(2) KI 645, dan (3) Kanesia 10. Pola tanam yang diterapkan adalahtumpangsari kapas dan kacang hijau yang ditanam di antara baris kapas.Setiap perlakuan disusun dalam rancangan petak terbagi dengan tiga kaliulangan. Ukuran anak petak adalah 10 m x 15 m. Pengamatan dilakukanterhadap (1) populasi nimfa A. biguttula dan predatornya, (2) frekuensipencapaian populasi ambang ekonomi, (3) skor kerusakan tanaman kapas,(4) hasil kapas berbiji dan kacang hijau, dan (5) analisis ekonomiperlakuan. Hasil  penelitian  menunjukkan  bahwa  setiap  teknikpengendalian yang diuji berpengaruh terhadap perkembangan populasi A.biguttula dan predatornya. Rata-rata pencapaian populasi ambangekonomi pada perlakuan benih (PB) dan kontrol lebih rendah (0,5–2 kali)dibandingkan dengan kombinasi perlakuan benih dan penyemprotankanopi (PBS) serta penyemprotan kanopi saja (S) yang mencapai 3–4 kali.Pada galur/varietas kapas yang diuji, pencapaian populasi ambangekonomi paling rendah terjadi pada galur 98050/9/2/4, diikuti oleh Kanesia10 dan KI 645. Perlakuan benih saja (PB) selain menurunkan populasi A.biguttula dan tidak menurunkan populasi predator, juga lebih efisiendibanding perlakuan lainnya dengan nilai marginal rate of return 1,38 danpeningkatan bersih 14,3%. Makna dari hasil yang diperoleh adalahpengendalian A. biguttula pada kapas dengan cara menyemprot kanopilebih baik dihindari apabila benih masih dapat diperlakukan, sedapatmungkin dikombinasikan dengan penggunaan varietas tahan/toleran.Kata kunci : Amrasca biguttula, imidakloprid, ambang ekonomi, galur/varietas, kapas, predator, marginal rate of return (MRR)ABSTRACTEffectiveness and Efficiency of Different ControlTechniques of Cotton Jassid, Amrasca biguttulaRecommendation for controlling jassid (A. biguttula) of cotton still relieson the use of combination of resistant variety and seed treatment(imidachloprid). Farmers, however, often spray chemical insecticides overplant canopy that also kill beneficial insects, including natural enemies.This study was conducted at Asembagus Experimental Station fromJanuary to November 2010. The objective of the study was to find out theeffectiveness and efficiency of control techniques against cotton jassid, A.biguttula. This field study consisted of two factors. First factor consistedof three different control techniques i.e. (1) seed treatment (PB), (2)without seed treatment and foliar application or control (TPB), (3)combination between seed treatment and foliar application (PBS), and (4)foliar application alone (S). Second factor consisted of three cottonvarieties, e.g. 98050/9/2/4, KI 645, and Kanesia 10. Treatments werearranged in a split plot design with three replicates. Cotton intercroppedwith mung bean planted in between cotton rows. Population of A. biguttulaand its predator, economic threshold achievement, score of plant injury,yields of cotton and mung bean were observed. Economic analysis of thetreatments was evaluated at the end of the experiment. Results showed thateach control techniques caused different effect on jassid and its predatordevelopment. The average of economic threshold achievement in seedtreatment application (PB) and control (TPB) were lower (0.5-2.0 times)compared to combination between seed treatment and foliar sprayed(PBS), also only foliar sprayed (3-4 times). Averaged of economicthreshold achievement on 98050/9/2/4 line was the lowest, followed byKanesia 10 and KI 645. Application of seed treatment (PB) not onlyreduced jassid population but also less effective on predator population. Itwas more efficient than other treatments with marginal rate 1.38 and didincrease net income by 14.3%. It means that foliar sprays to control A.biguttula on cotton should be ignored, if applying seed treatment andresistant/tolerant varieties.Key words: Amrasca biguttula, imidachloprid, economic threshold,cotton cultivar/variety, predator, marginal rate of return(MRR)

Abstract

ABSTRAKKontribusi sifat hermaprodit terhadap daya hasil tanaman jarakpagar belum banyak diketahui. Tujuan penelitian adalah mengetahui peranbunga hermaprodit terhadap daya hasil dan mekanisme pewarisannya.Penelitian dilakukan terhadap 60 genotipe jarak pagar di Kebun PercobaanBalittri Sukabumi. Penelitian dilaksanakan mulai bulan Mei 2007 sampaidengan Juli 2010. Jarak tanam 2 m x 2 m, menggunakan 2,5 kg pupukkandang + 20 g Urea + 20 g SP 36 + 10 g KCl per tanaman. Penelitianterdiri dari (1) evaluasi tipe bunga jarak pagar dan (2) pewarisan sifathermaprodit dan kontribusinya terhadap daya hasil. Hasil evaluasimenunjukkan bahwa delapan dari 60 genotipe jarak pagar yang dievaluasimerupakan tanaman tri-monoecious yang menghasilkan bunga jantan,bunga betina, dan bunga hermaprodit, 52 lainnya merupakan tanamanmonoecious yang hanya menghasilkan bunga jantan dan bunga betina.Karakter yang dimiliki oleh delapan genotipe tri-monoecious yangdievaluasi adalah lebih lambat berbunga (mulai berbunga pada umur 120-274 hari) dan berdaya hasil rendah sampai sedang (jumlah buah 23-228per tanaman pada tahun pertama). Kemunculan bunga hermaprodit tidakterjadi sepanjang tahun, tetapi lebih dominan pada tanaman berumur enambulan. Persentase bunga hermaprodit berkisar 6,25-53% dari total bungayang dihasilkan. Persentase fruitset pada tandan bunga hermaprodit lebihtinggi dibanding tandan bunga non-hermaprodit, dengan tingkatkeberhasilan rata-rata 80% (kisaran 56-100%). Pada tandan bunga yangtidak menghasilkan bunga hermaprodit, buah jadi rata-rata sebesar 50%(kisaran 11-100%). Daya hasil tanaman jarak pagar ditentukan olehgenetik tetua. Bunga hermaprodit diwariskan oleh tetua betina maupuntetua jantan. Gen pengendali sifat hermaprodit diduga adalah gensederhana yang bersifat dominan.Kata kunci: Jatropha  curcas,  monoecious,  tri-monoecious,  bungahermaprodit, fruit setABSTRACTHermaphrodite character has been reported in physic nut, its roleand contribution to production process especially to the yield has not beeninvestigated. The objectives of this research were to evaluatehermaphrodite flowers contribution on yield and their mechanisminheritance. The evaluation was conducted at the Experimental Station ofBalittri Sukabumi from May 2007 to July 2010. The spacing was 2 m x 2m with 2,5 kg manure + 20 g Urea + 20 g SP 36 + 10 g KCl/plant. Theexperiment consisted of (1) evaluation of flower type of physic nut and(2) hermaphrodite inheritance and their contribution on yield. Results ofthe experiment indicated eight from 60 physic nut genotypes were tri-monoecious which were capable on producing male, female, andhermaphrodite flowers while as the rest (52 genotypes) were monoeciouswhich produced only male and female flowers. The tri-monoecious weregenerally late flowering (120-274 days after planting) and low to mediumyield (producing 23-228 fruits per plant in the first year). Hermaphroditeflowers generally occurred six months after planting at the amount rangedfrom 6,25-53% of total flowers. Fruit set of inflorescences havinghermaphrodite flowers was higher, average of 80% (ranged from 56-100%) than those with female and male flowers, average of 50% (rangedfrom 11-100%). Yield of physic nut was affected by the genetic potentialof their parents rather than hermaphrodite character. Hermaphrodite flowercharacter was inherited by both female and male parents and might becontrolled by simple-dominant gene.Key words: Jatropha curcas, monoecious, tri-monoecious, hermaphroditeflower, fruit set

Abstract

ABSTRAKSebagai tanaman indeterminit, kapas (Gossypium hirsutum) mem-perlihatkan pola pertumbuhan yang memungkinkan bertahan darikehilangan sejumlah komponen produksi tanpa kehilangan hasil secaranyata. Dengan kata lain tanaman kapas mampu melakukan pemulihan(recovery) dan kompensasi setelah kerusakan akibat serangan hama.Penelitian tentang kemampuan pemulihan aksesi kapas sebagai responterhadap kerusakan oleh kompleks hama penggerek buah secara simulasiini dilakukan di KP Karangploso, Balai Penelitian Tanaman Tembakaudan Serat, Malang, mulai Januari hingga Desember 2009. Tujuannyaadalah untuk mengetahui kapasitas pemulihan aksesi kapas setelahserangan hama dan kemampuan melakukan kompensasi. Sepuluh aksesikapas, yaitu: (1) L57x1124-81-411, (2) M35-5-2, (3) 40727-2xNL-11-1-73-1, (4) HG10x1209-619-9-76, (5) NC-177-16-C2, (6) 731Nx1656-12-76-2, (7) Stoneville 825, (8) 619-998xLGS-10-77-3-1, (9) NMG 1222, dan(10) NMG-5-2 diuji dalam penelitian ini dengan menggunakan rancanganacak kelompok (RAK) dengan tiga kali ulangan. Setiap aksesi kapasditanam dalam kantong-kantong plastik berukuran 10 kg dengan duatanaman per kantong. Satu tanaman diperlakukan dengan cara meng-hilangkan seluruh kuncup bunga yang ada setelah tumbuh 9-13 daun padabatang utama yang dilakukan selama 21 hari dengan interval 3 hari.Sedangkan satu tanaman lainnya dibiarkan tumbuh normal (kontrol).Parameter yang diamati adalah: luas daun, bobot kering tanaman, indekspemulihan, jumlah node, tinggi tanaman, luas daun, jumlah kuncup bunga,hasil kapas, dan persentase kompensasi. Hasil penelitian menunjukkanbahwa tanaman kapas tahan, moderat, dan rentan serangan hama mampumelakukan pemulihan (recovery) dari kerusakan. Berdasarkan luas daun(R L ) dan bobot kering (R B ), setiap aksesi mempunyai indeks pemulihanyang berbeda-beda dan diantaranya ada yang berbeda nyata. Beberapaaksesi dengan kapasitas pemulihan tinggi memiliki tinggi tanaman, jumlahkuncup bunga, dan hasil kapas lebih tinggi dibanding tanaman kontrol.Dampak dari pemulihan juga terlihat pada perbedaan persentasekompensasi.

However, it was unclear to what extent can cotton toleratedamage before and after the onset of fruiting. This field study was carriedout at Karangploso Experimental Station of Indonesian Tobacco and FiberCrops Research Institute (ITOFCRI) Malang from January to December2009. The aim was to know the capacity of cotton accessions to recoverafter damage. Ten cotton accesssions as treatment were planted in polybagand were arranged in randomized block design with three replicate. Tenaccessions of cotton used as treatment were: (1) L57x1124-81-411, (2)M35-5-2, (3) 40727-2xNL-11-1-73-1, (4) HG10x1209-619-9-76, (5) NC-177-16-C2, (6) 731Nx1656-12-76-2, (7) Stoneville 825, (8) 619-998xLGS-10-77-3-1, (9) NMG 1222, and (10) NMG-5-2. Each accessionwas plantation in four polybags with two plants in each polybag. One plantin each polybag was damaged manually by removing all squares (100%)for 21 days at a three-day interval, while another plant was as anundamaged control. Parameters observed in this study were leaf area, dryweight of plant, indices of recovery ( R ), number of main-stem nodes, theaverage of plant height, number of square, and yield of cotton. Resultshowed that all accessions showed their ability to recover after damagedand the recovery indices based on leaf area (R L  ) and dry weight (R w )varied among the accessions tested. Accessions with high recovery abilityperformed better plant height, square formation, and cotton yield than thatof undamaged control. Effect of good recovery was resulting in higherpercentage of plant compensation. NMG-5-2, Stoneville 825, 731Nx1656-12-76-2, 619-998xLGS-10-77-3-1, 40727-2xNL-11-1-73-1, and NMG-1222 were accessions with average compensation percentage was greaterthan 15% : 36.6; 34.5; 31.3; 26.6; 20.4; and 19.2%, respectively whencompared with undamaged control.Key words: Accession, indices of recovery, insect complex, simulation
