The aim of the research was to identify the effect on gamma ray irradiation on vegetative growthand production of local onion (Allium ascalonicum L.) Var. samosir. The research was conducted atJl. Pancing, Medan, North Sumatera, with a height of 25 m above sea level began from April up toJuly 2014. Bulbs of onion were exposed to various doses of gamma irradiation (0, 2, 4, 6, 8, 10, 12and 14 Gy) using Co60 source. Parameters observed were shoot length, leaves number, tillersnumber, harvesting age, bulb fresh weight, bulb dried weight, bulb diameter and average weight perbulb. The results showed significant difference between irradiated and unirradiated plants (control)growth and production. All parameter observed were lower than control. Irradiated plants 6 weeksafter planting at doses 6,8,10 12 Gy reduced shoot length 24.5%, 35.4%, 54.07%, 64.19%; leavesnumber 36.30%, 46.54%, 45.28%, 69.74%, respectively compared to control. There was no plantsustein alife at doses of 10, 12 and 14 in 7 weeks after planting. Irradiated plants at doses of 6 and 8Gy also reduced bulb fresh weight 56.40%, 70.85%, bulb dried weight 58.61%, 76.15%, bulbsdiameter 31,09% , 44.12%, average weight per tuber 59.6%, 78.45% respectively compared tocontrol.Keywords: onion, var. samosir, gamma ray irradiation

Abu vulkanik yang mengandung hara penyubur tanah untuk pertanian sebenarnya baru bisa dimanfaatkan sekitar 10 tahun setelah peristiwa meletusnya gunung, namun teknologi percepatan pelapukan abu vulkanik dapat dilakukan dengan mencampur bahan organik. Salah satu bahan organik yang mampu untuk melepaskan hara yang terikat dari abu vulkanik yaitu arang sekam padi. Penelitian ini bertujuan untuk mengidentifikasi respons pertumbuhan dan produksi tanaman bawang merah (Allium ascalonicum L.) terhadap pemberian abu vulkanik Gunung Sinabung dan arang sekam padi. Penelitian dilaksanakan di lahan percobaan Fakultas Pertanian USU mulai bulan Mei ˗ Agustus 2014, menggunakan rancangan acak kelompok faktorial dengan dua faktor yaitu pemberian abu vulkanik (0, 5, 10, 15 ton/ha) dan arang sekam padi (0, 10, 20 ton/ha). Peubah yang diamati adalah jumlah anakan, bobot basah per sampel, bobot basah per plot, bobot kering per sampel, dan bobot kering per plot. Hasil penelitian menunjukkan bahwa pemberian arang sekam padi belum kelihatan mempercepat pelapukan abu vulkanik. Pemberian abu vulkanik dan arang sekam padi berpengaruh tidak nyata terhadap semua peubah amatan, tetapi interaksi keduanya berpengaruh nyata terhadap jumlah anakan pada 3 MST. Kombinasi perlakuan tanpa abu vulkanik dan arang sekam padi 10 ton/ha menghasilkan jumlah anakan per rumpun terbanyak.Kata kunci : abu vulkanik, arang sekam padi, bawang merah

The aim of the research was to identify the effect of GA3 concentration and soaking period on the seed yield of shallot. Research was conducted at Hatoguan Village, Palipi Subdistrict, Samosir from February up to July 2014, carried out by using randomizes block design with two factors, replicated three times. The first factor was GA3 concentrations (50 ppm; 100 ppm; 150 ppm; 200 ppm; and 250 ppm) and the second was soaking period (30; 60; and 90 minutes). Parameters observed were the number of plant producing flowers per plot, the number of umbel per plot, seed weight per umbel, and seed weight per plot. The results showed that among all parameters observed, only the number of plants producing flowers per plot and seed weight per umbel were affected by GA3 concentration. The highest number of plants producing flowers and seed weight per umbel were produced by G4 (200 ppm GA3) i.e 10,780 plants (43,12 %) and 0,202 g respectively. Meanwhile, only seed weight per umbel was significantly affected by soaking period. The correlation between soaking period and seed weight per unbel showed positive linear regression.Key word: GA3 consentration, soaking period, shallot

The aim of the research was to identify the influence of GA3 Concentration and Dose of Boron on the seed yield of Samosir Shallot Sagala accesion. The research was conducted at Hatoguan Village, Subdistrict Palipi, Samosir, began from February until July 2014, using factorial randomized block design with two factors, replicated three times. The first factor was GA3 concentration (0, 50, 100, 150, 200 and 250 ppm) and the second was dose of boron (0, 1.5, 3 and 4.5 kg/ha). Parameters observed were percentage of flowering plants per plot, umbels number per plot, seeds weight per umbel and seeds weight per plot. The results showed that the percentage of flowering plants per plot was significantly affected by GA3 concentration, and seed weight per umbel by dose of boron. The highest percentage of flowering plants per plot was 41,27% produced by G4 (200 ppm GA3), and the corelation between dose of boron and seed weight per umbel showed positive linear regression. However all other parameters were not significantly affected by both treatments.Kata kunci : GA3 Concentration, Dose of Boron, Shallot

The aims of the research was to analize the growth and yield response of shallots (Allium ascalonicum L.) on the doses of phospate fertilizer and humic acid. The research was conducted at Jl. Pasar 1 Ringroad Medan from August to November 2014, using a factorial randomized block design with two factors replicated three times. The first factor is the doses of phosphate fertilizers (90, 72, 54, 36 kg / ha) and the second is the doses of humic acid (0, 1.5, 3 kg / ha). Parameters observed were number of leaves, number of tillers, wet weight per sample, dry weight per sample, the rate of net assimilation, the rate of relative growth, and the rate of plant growth. The result showed that only number of leaves 4 week after planting was significantly affected by the interaction between fosfate fertilizers and humic acid, which the most number of leaves was 19.67 produced by combination of 36 kg/ha phosphate fertilizer and 3 kg/ha humat acid and at 5,6 and 7 week after planting was significantly affected by humic acid. Meanwhile, all other parameters observed were not significantly affected by all treatments.Keywords: Fosfate fertilizer, humic acid, shallots

The aim of the research was to identify the influence of several types of organic fertilizer on the growth and yield of three shallot varieties on the land exposed by Sinabung volcanic ash. The research was conducted at the experimental field of Agricultural Faculty, Sumatera Utara University which about ± 25 metres above sea level, begun from April up to August 2014. The experimental design was randomized block design with 2 factors, replicated three times. The first factor was three shallot varieties i.e : V1 (Bima Brebes), V2 (Crok Kuning), V3 (Samosir) and the second was several types of organic fertilizer i.e : P0 (without fertilizer = control), P1 (palm oil fruit bunch), P2 (rice husk ash), and P3 (cow manure). Parameters observed were shoot length, leaves number, tillers number, clove number, harvesting age, and fresh and dried weight bulb per sample. The results showed that all parameters observed were significantly affected by three shallot varieties, meanwhile only harvesting age, and wet and dry weight bulb per plot were significantly affected by several types of organic fertilizer. There was no interaction between both treatments.Keywords: varieties, organic fertilizer, volcanic ash, shallot

The aim of this research was to identify the morphological characteristics of several local Samosir shallot which was conducted in Bakti Raja, Humbang Hasundutan district i.e. Siunong-unong Julu, Marbun Dolok, Simamora, Marbun Toruan, Sinambela-Simanulang and Simangulampe start from July till August 2015. This research was implemented by using randomized block design non factorial with 3 replicants. The parameters observed were time flowering, leaves colour, bulbs shape, bulbs colour, plant length, leaves number, tillers number per clump, wet bulbs weight, dry bulbs weight, bulbs number per clump, diameter of bulbs, 100 bulbs dry weight, wet-dry bulbs weight decrease. The result of research showed local Samosir shallot in six accession in Bakti Raja districts have narrow kuantitative related. The morphological differentiator characteristic of the accessions was wet bulbs weight. The potential yields of each accession shown that the shallot from Marbun Toruan has the highest yields potential i.e 15,20 ton/ha then Siunong-unong Julu i.e 12,00 ton/ha, Simangulampe i.e 11,93 ton/ha, Simamora i.e 11,76 ton/ha, Sinambela-Simanulang i.e 11,36 ton/ha and Marbun Dolok i.e 11,07 ton/ha wet bulbs.
