Abstract

The growth of oil palm seedlings (Elaeis guineensis Jacq.) by the application of rice husk andfrequency of watering in the main nursery. This research aims to study aimed to determine thegrowth of oil palm seedlings to rice husk and watering frequency on the main nursery. This researchwas conducted in Greenhouses in the Faculty of Agriculture, University of North Sumatera, Medanwith ± 25 m altitude above sea level in January 2013 to April 2013 using a factorial randomizedblock design with two factors: Media planting rice husk (0:0, 2: 1, 1:1, 1:2) and watering frequency(1, 2, 3 days) parameters measured were plant height, stem diameter, number of leaves, total leafarea, fresh weight of seedlings, seedling dry weight. The results showed that treatment of rice huskgrowing media influence is not obvious to all treatment parameters. Watering frequency treatmentssignificantly affected stem diameter parameter 2 and 6 MST with the highest yield obtained in thetreatment of the frequency of watering every other day. Both treatment interaction effect was notsignificant on all treatments.Keywords: palm oil, rice husk, watering

Abstract

ABSTRACT This research was conducted to obtain dose of chicken manure and cow urine which can improve the growth and production of the shallot. The research was conducted at experimental field of Agricultural Faculty of Sumatera Utara University, Medan which about ± 25 metres above sea level, begun from May until August 2015 using factorial randomized block design with two factors, i.e: doses of chicken manure (no chicken manure, 1.9 kg/plot, 2.9 kg/plot and 3.9 kg/plot) and doses of cow urine (no cow urine, 500 ml/plot, 600 ml/plot, 700 ml/plot). Parameters observed were plant lenght, number of tillers per clump, diameter of the bulbs per sample, wet bulb weight per plot, and dry bulb weight per plot. The results showed that aplication of chicken manure significantly affected plant length at 3 - 7 weeks after planting, number of tillers per clump at 3 - 7 weeks after planting, dry bulb weight per sample, wet bulb weight per plot, and dry bulb weight per plot. Aplication of cow urine not significantly affected on all parameters of observation. Interaction between aplication of chicken manure and cow urine not significantly affected on all parameters of observation.Keywords : shallot, chicken manure, cow urine  ABSTRAK Penelitian ini bertujuan untuk mendapatkan dosis pemberian pupuk kandang ayam dan urine sapi tertentu yang dapat meningkatkan pertumbuhan dan produksi bawang merah. Penelitian dilaksanakan di lahan percobaan Fakultas Pertanian Universitas Sumatera Utara, Medan dengan kepanjangan ± 25 meter di atas permukaan laut, pada bulan Mei hingga Agusutus 2015. Metode penelitian menggunakan rancangan acak kelompok faktorial dengan dua faktor, yaitu: pupuk kandang ayam (tanpa pupuk kandang ayam, 1.9 kg/plot, 2.9 kg/plot dan 3.9 kg/plot) dan pemberian urine sapi (tanpa urine sapi, 500 ml/plot, 600 ml/plot, dan 700 ml/plot). Parameter yang diamati adalah panjang tanaman, jumlah anakan per rumpun, diameter umbi per sampel, bobot basah umbi per plot, dan bobot kering jual umbi per plot. Hasil penelitian menunjukkan bahwa pemberian pupuk kandang ayam berpengaruh nyata terhadap parameter panjang tanaman umur 3 - 7 MST, jumlah anakan per rumpun umur 3 - 7 MST, diameter umbi per sampel, bobot basah umbi per plot, bobot kering jual umbi per plot. Pemberian urine sapi berpengaruh tidak nyata terhadap semua parameter pengamatan. Interaksi antara pemberian pupuk kandang dan urine sapi berpengaruh tidak nyata terhadap semua parameter pengamatan. Kata kunci : bawang merah, pupuk kandang ayam, urine sapi
