For the last six years in a row, the yield of peanut in Indonesia had encountered the decreasingyield problem. In case of that, the using chicken manure as organic material and NPK (15:15:15)fertilizer were aimed to increase growth and yield of peanut. The research has been conducted at theexperimental fields of Agriculture Faculty, Universitas Sumatera Utara, Medan from October 2013until February 2014. This research used factorial randomized block design with two factors, i.e.doses of chicken manure (0; 25; 50; 75 g/polybag) and doses of NPK (15:15:15) fertilizer (0; 0,625;1,25; 1,875 g/polybag). Parameters observed were number of branches, flowering age, gynophoresformed, pods per sample, pods per plot, seed weight per sample, dry weight of 100 seeds, freshweight of biomass, and dry weight of biomass. The results showed that the treatment of usingchicken manure significantly influenced the parameters of branches, gynophores formed persample, pods per sample, pods per plot, seed weight per sample, wet weight biomass per sample anddry weight biomass per sample. The treatment of NPK (15:15:15) significantly influenced theflowering age and dry weight of 100 seeds. The interaction between the both of treatmentsignificantly influenced dry weight of 100 seeds.Keywords : peanut, chicken manure, NPK (15:15:15) fertilizer

Palm oil is one of the major and prime agricultural commodities in Indonesia. Better palm oilseedling growth depend on nutrient and organic matter availability that can be fullfilled by usingpalm oil mill effluent (POME) and NPKMg (15:15:6:4) fertilizer. The objectives of the researchwere to study growth response of palm oil pre nursery seedling to aplication of POME and NPKMg(15:15:6:4) fertilizer. The research was held at screen house of Agricultural Faculty USU (±25 m asl) in April to July 2014 using a factorial randomized block design with two factors and threereplications. The first factor were POME (0; 1.5; 3.0; 4.5 l/seedling) and the second factor wereNPKMg (15: 15: 6: 4) fertilizer (0; 2.5; 5.0; 7.5 g/seedling). Data were analyzed with ANOVA andcontinued with Duncan multiple range test. The Parameters observed were plant height, stemdiameter, leaves number, total leaf area, leaves greenness, fresh and dry root and upper part weight.The results obtain were the effect of POME until dose L (3.0 l/seedling) were increase for allparameters except leaves greenness, fresh and dry root. The effect of NPKMg (15:15:6:4) fertilizeruntil dose P22 (5.0 g/seedling) increase for all parameters except stem diameter. The interaction ofthese two factors until L3Pwere increase leaves number, leaves greenness, fresh root weight, freshand dry upper part weight.Keywords: palm oil mill effluent, NPKMg (15:15:6:4) fertilizer, palm oil seedling 3

Pomegranate seed requires dormancy breaking treatment to encourage germination. One of dormancy breaking treatments that can be done is soaking on sulphuric acid (H2SO4). This study aimed to determine the effect of concentration and duration of soaking sulphuric acid (H2SO4) on the viability of pomegranate seeds. This research was conducted at the Laboratory of Seed Technology Faculty of Agriculture, University of Sumatra Utara, Medan with a height of ± 25 meters above sea level, in April 2015, using a completely randomized design with 10 degree factor dormancy breaking treatments that seed soaking treatment with H2SO4 (25%, 50%, 75%) with duration of soaking (10 minutes, 15 minutes, and 20 minutes). Parameters measured were tetrazolium test (%), germination rate (day), normal seedling (%), abnormal seedling (%), seed that has not grown (%), vigor index, fresh weight seedling (g), dry weight seedling (g). The results showed that seed soaking treatment with 75% H2SO4 for 10 minutes increased the percentage of germination rate (day), normal seedling (%),vigor index, fresh weight seedling (g), dry weight seedling (g), but not to tetrazolium test (%).Keywords: pomegranate seeds, viability, dormancy, sulphuric acid

Penelitian ini bertujuan untuk mengetahui pengaruh populasi dan pemberian pukan ayam terhadap pertumbuhan dan produksi bawang merah (Allium ascalonicum L.). Penelitian dilakukan di lahan penduduk, Kota Medan pada Agustus sampai November 2015. Penelitian ini menggunakan Rancangan Petak Terpisah dengan 2 faktor yaitu dosis pukan ayam sebagai petak utama (0, 12.5 dan 25 ton/ha) dan populasi tanaman sebagai anak petak (25, 50, 75 dan 100 tanaman/m2). Parameter yang digunakan adalah panjang tanaman, jumlah daun, jumlah anakan, bobot basah per sampel, bobot kering per sampel, bobot basah per plot, bobot kering per plot dan diameter umbi. Hasil penelitian menunjukkan pemberian pukan ayam berpengaruh nyata pada panjang tanaman, jumlah anakan, bobot basah umbi per plot dan bobot kering umbi per plot. Interaksi antara keduanya berpengaruh nyata pada parameter panjang tanaman dan jumlah anakan. Berdasarkan bobot kering umbi per plot yang terbaik (1287.92 g ) maka perlakuan terbaik adalah pukan ayam 25 ton/ha, sedangkan jumlah populasi berpengaruh tidak nyata terhadap semua perlakuan.
