Pengaruh Lokasi Produksi Dan Lama Penyimpanan Terhadap Mutu Benih Jahe (Zingiber Officinale L.)

Salah satu permasalahan dalam budidaya jahe (Zingiber officinaleL.) adalah masih rendahnya produktivitas dan mutu jahe, yang antara laindisebabkan oleh penggunaan bahan tanaman/benih yang masih asalan/kurang memenuhi persyaratan. Usaha untuk penyediaan benih yangbermutu di antaranya dapat dilakukan dengan penanaman di daerah yangtepat serta menyimpan benih dengan cara yang baik dan benar. Sampaisaat ini informasi mengenai mutu benih jahe dari lokasi produksi(ketinggian tempat, jenis lahan dan jenis tanah) yang berbeda masihterbatas. Oleh karena itu, percobaan ini dilakukan dengan tujuan untukmempelajari mutu fisik dan fisiologik benih jahe dari lokasi produksiyang berbeda selama periode penyimpanan. Percobaan dilakukan di daerahsentra produksi jahe di Dusun Cipanas, Desa Werasari, KecamatanBantarujek, Kabupaten Majalengka, Jawa Barat dari bulan Juli sampaiNovember 2003, dengan menggunakan tiga jenis jahe yaitu: Jahe PutihBesar/JPB (Z. officinale var. officinale), Jahe Putih Kecil /JPK (Z.officinale var. amarum), dan Jahe Merah/JM (Z. officinale var. rubrum).Untuk masing-masing jenis jahe diperlakukan dengan kombinasi lokasiproduksi dan lama penyimpanan. Untuk masing-masing jenis jahepercobaan disusun dalam rancangan petak terbagi (RPT) dengan tigaulangan. Petak utama yaitu asal lokasi produksi benih: (1) Cipanaslingkungan tumbuh dengan tinggi tempat ± 600 m dpl, lahan sawah tadahhujan, tekstur tanah liat berpasir, kemiringan 0-10% dan (2). Cipicunglingkungan tumbuh dengan tinggi tempat ± 800 m dpl, lahan tegalan,tekstur tanah debu berpasir, kemiringan 10-20%. Anak petak yaitu periodepenyimpanan : 0, 1, 2, dan 3 bulan. Parameter yang diamati meliputi kadarair benih, penyusutan bobot benih dan daya tumbuh benih. Hasilpenelitian menunjukkan bahwa untuk masing-masing jenis jahe (JPB,JPK, dan JM) yang berasal dari Cipanas maupun Cipicung, mempunyaimutu fisik (kadar air dan penyusutan bobot rimpang) tidak nyatadipengaruhi oleh interaksi lokasi produksi dan lama penyimpanan, sertafaktor tunggal lokasi produksi, tetapi nyata dipengaruhi oleh faktortunggal lama penyimpanan Setelah tiga bulan penyimpanan kadar airbenih rimpang dari lokasi produksi Cipanas dan Cipicung untuk JPB masih82,43% dan 80,67%, JPK kadar airnya masih 84,16% dan 81,31%, danJM 69,49% dan 65,88%. Penyusutan bobot rimpang untuk masing-masingjenis jahe dari lokasi produksi Cipanas dan Cipicung sebagai berikut : JPB14,44% dan 14,82% ; JPK 17,84% dan 26,11% ; JM 48,40% dan 37 14%.Daya tumbuh benih setelah 3 bulan penyimpanan untuk masing-masingjenis jahe dari lokasi produksi Cipanas dan Cipicung sebagai berikut : JPB92,00- 93,32%, JPK 85,33- 86,67% dan JM 86,67-89,33%. Kadar airbenih/rimpang jahe menurun, sedangkan penyusutan bobot rimpangmeningkat sejalan dengan lamanya penyimpanan. JPB, JPK dan JM yangberasal dari Cipanas maupun Cipicung dapat disimpan selama tiga bulan,tanpa mengalami penurunan mutu fisik dan fisiologik yang berarti

Pengaruh Batang Atas Dan Bawah Terhadap Keberhasilan Penyambungan Jambu Mete (Anacardium Occidentale L.)

Effect of scion and root stock on successful grafting ofcashew plantCashew nut production of Indonesia is lower (350 kg/ha/year)compared to India and Brazil (800 and 1000 kg/ha/year). There are manyfactors causing low production of cashew in Indonesia such as lowcultivation technology, poor quality of seedlings and insufficient of motherplants. The purpose of the research was to find out good quality seedlingsfrom grafting as a basic to establish cashew mother plants gardens. Theexperiment was conducted in Muktiharjo Experimental Garden, CentralJava, in 2001. The experiment was arranged in split-plot design with 3replications. The main plot was 4 kinds of scions namely Gunung Gangsir1, Gunung Gangsir 2, Muktiharjo1 and Muktiharjo 2. The sub plot was 4kinds of root stocks the same as the scions. Variables observed weresuccessful grafting at nursery phase and plant growth such as height ofplants, diameter of trunk, diameter of canopy, and number of primer,secondary and tertiary branches. The results of experiment showed thatgrafting by using clone Muktiharjo 1 as root stock, and Muktiharjo 1 andMuktiharjo 2 as scions produced the highest percentage of successfulgrafting (50%). Grafting by using Gunung Gangsir 1 as root stock and,Muktiharjo 1 and Muktiharjo 2 as scions produced the lowest percentageof successful grafting (38.89%). There were no significant interactionsbetween root stock and scion on the growth of cashew plant. Scion hadsignificant effect on the number of leaves, but, it did not have significanteffect on the plant height, diameters of trunk and diameters of canopy.Grafting by using Gunung Gangsir 1 and Muktiharjo 2 as scions producedbetter plant growth compared to those of Gunung Gangsir 2 andMuktiharjo 1 as scions. Grafting by using Gunung Gangsir 1, GunungGangsir 2 and Muktiharjo 1 as root stocks produced diameter of trunk andheight of plants better than that of Muktiharjo 2 as rootstock. At 3 yearsold after planting, scions did not significantly affect the plant growthneither did their interaction. While rootstock significantly affected thegrowth of cashew plant. As a rootstock, Gunung Gangsir 1, produced thebest cashew plant growth compared to other clones

Pengaruh Umur Panen Terhadap Viabilitas Benih Serta Hubungannya Dengan Produksi Terna Sambiloto (Andrographis Paniculata Nees

The influence of harvesting time on the seed viability andthe relationship with herb yield of king bitter(Andrographis paniculata Nees)One of the main factors influencing the viability of king bitter(Andrographis paniculata Nees) is appropriate harvesting time. Based onthis problem a research was conducted to study the relationship betweenseed maturity and seed viability, and herb yield of king bitter. The researchwas conducted at Cimanggu Experimental Station and in the laboratory ofIndonesian Medicinal and Aromatic Crops Research Institute (IMACRI)from March 2005 to March 2006. The experiment was arranged in arandomized block design with 10 seed maturity stages and 4 replications.Maturity seed tested was 18, 21, 22, 23, 24, 25, 26, 27, 28 and 29 daysafter anthesis. The observations were made on seed quality (percentage ofseed germination, and rate of seed germination), plant growth (plantheight, number of branches) and herb yield (fresh herb weight, leaf dryweight, and stem dry weight). The results of experiment indicated that (1)seed maturity affected seed germination, and rate of seed germination ofking bitter; the highest seed germination and germination rate wereachieved by seeds harvested at 21 and 22 days after anthesis, (2) stage ofseed harvesting affected on the plant height and number of branches at 1month after planting. The highest plant height and number of brancheswere found on the treatments of seeds harvested at 26 and 27 days afteranthesis, they were 39.63 and 36.58 cm and 16.71 and 16.61; (3) seedmaturity also affected herb production, such as wet weight of plants, dryweight of leaf and dry weight of steam at 3 moths after planting. Wetweight of plant, dry weight of leaf and dry weight of stem were achievedat the treatments of seeds harvested at 27 days after anthesis, they were291.25, 28.27 and 28.86 g. The lowest of wet of plant weight, dry weightof leaf and dry weight of stem were found on the seeds harvested at 18days after anthesis. They were 217.09, 22.10 and 20.24 g. Moreover, thestage of harvesting did not influence the number of branches at 3 monthsafter planting

Production of Soybean Varieties Under Saturated Soil Culture on Tidal Swamps

Saturated soil culture (SSC) is a cultivation technology that gives continuous irrigation and maintains water depth constantly and makes soil layer in saturated condition. By keeping the water-table constantly, soybean will be avoided from negative effect of inundation on soybean growth because soybean will acclimatize and improve its growth. The objective of the research was to study the response of soybean varieties under saturated soil culture on tidal swamps. The research was conducted at Banyu Urip of Tanjung Lago Sub District, Banyuasin District, South Sumatera Province, Indonesia from April to August 2009. The experiment was arranged in a split plot design with three replications. The main plot was water depth in the furrow consisted of without watering, 10, 20, 30, 40 cm under soil surface (uss). The subplot was soybean variety consisted of Tanggamus, Slamet, Willis, and Anjasmoro. The result showed that the interaction between varieties and water depth significantly affected growth and seed production, except pod numbers/plant. The values of all variables were higher under SSC compared to those cultivated without watering (control), but varieties responded to SSC differently. The highest seed production was obtained from Tanggamus with 40 cm uss, i.e. 4.83 ton/ha but it was not significantly different from those at water depth 20 (4.63 ton/ha) and 30 cm uss (4.71 ton/ha). However, technically and economically, 20 cm uss was the most appropriate water depth for soybean production on tidal swamps
