The purpose of this research was to determinate the growth response of embryogenic callus from some varieties of soybean (Glycine max (L.) Merrill) on hypoxic and in vitro condition. The research was conducted at The Tissue Culture Laboratory of Agriculture Faculty in University of Sumatera Utara on April until December 2016. This research had two stages, induction of embryogenic callus and analysis metabolism of callus after hypoxic condition with t-test. This analysis used factorial Completely Randomized Design with two factors. The first factors were varieties of soybean and the second factors were combination of Plant Growth Regulator (PGR) (5 mg/l 2,4-D + 1 mg/l BAP, 10 mg/l 2,4-D + 1,5 mg/l BAP, and 15 mg/l 2,4-D + 2 mg/l BAP). The result showed the varieties, combination of PGR, and interaction of varieties and PGR give significant effect to weight callus. The result of T-test showed that in hypoxic condition, POD enzyme exercise on Gepak Kuning’s callus in 5 mg/l 2,4-D + 1 mg/l BAP was different before and after hypoxic condition. Keywords : 2,4-D, BAP, embryogenic callus, hypoxic, soybean

The research was aimed to know that accumulation of lead in soil and mustard due to urban waste compost application. The researh was held in gauze house and analyzed in Balai Pengkajian Teknologi Pertanian (BPTP) Laboratory, North Sumatera in April -July 2016. The research used randomized block design factorial with two treatment factors those are the depth of layers of urban waste compost with 3 level of treatment ; S1 (upper layer), S2 (middle layer), S3 (bottom layer) and growing media composition with 5 level of treatment ; M0 (100% soil), M1 (25% compots + 75% soil), M2 (50% compost and 50% soil), M3 (75% compost + 25% soil), M4 (100% compost) with 3 replications. The result showed that giving25% urban waste compost can increase of production of mustard, soil pH, soil C-organic, total Pbsoil and Pb in plants and it’s value exceeds the threshold. The depth of layers of urban waste compost significant effect on total Pb soil and Pb in plants and it’s value exceeds the threshold. Interaction amount of compost and the depth of layers of urban waste compost were not significant increased of production of mustard, but significant increased of soil pH, soil C-organic, total Pbsoil and Pb in plants.

Publisher : Universitas Sumatera Utara

Kedelai merupakan salah satu komoditi pangan yang penting di Indonesia karena dapat digunakan sebagai pangan, pakan, maupun bahan baku industri pengolahan namun angka produksinya masih tergolong sangat rendah yaitu sebesar 1.57 ton/ha. Tujuan penelitian ini adalah untuk mengetahui respons pertumbuhan dan produksi beberapa varietas kedelai terhadap pemberian berbagai sumber hara K. Penelitian ini dilaksanakan di Tanjung Sari, kecamatan Medan Selayang, Medan mulai bulan Juni sampai dengan September 2016. Penelitian ini menggunakan Rancangan Acak Kelompok dengan 2 faktor perlakuan. Faktor pertama adalah varietas yang terdiri dari 3 varietas yaitu varietas Dering-1, Anjasmoro, dan Grobogan. Perlakuan kedua adalah pemberian berbagai sumber hara K yang terdiri dari 4 taraf perlakuan yaitu tanpa hara K (kontrol), KCl 75 kg/ha, abu janjang kelapa sawit 150 kg/ha, dan abu sabut kelapa 180 kg/ha. Hasil penelitian menunjukkan bahwa perlakuan varietas nyata meningkatkan tinggi tanaman pada umur 2-6 MST, luas daun, bobot kering biji/ plot, dan bobot kering 100 biji. Pemberian sumber hara K dan Interaksi antara varietas dengan pemberian sumber hara K berpengaruh tidak nyata terhadap seluruh peubah amatan yang diamati. Kata Kunci : kalium, kedelai, varietas

ABSTRACT Goosegrass (Eleusine indica) on rubber fields at Rambutan estate PTPN III had been sprayed using glyphosate for 28 years continuously. Lately it was reported that the herbicide glyphosate was no longer effective to control E.indica in that area. The objective of this study was to determine the spread and resistance levels of E. indica populations to glyphosate found in 14 Divisions of Rambutan Estates. The 14 populations were compared to a population collected from the University of Sumatera Utara where no herbicides had been sprayed previously. The plants were sprayed with 480 g a.i IPA glyphosate at 4-5 leaf stage. Experiment was arranged using fully randomized design non factorial, with the populations of, ESU0, ESU5.1, ESU5.2, ESU5.3, ESU5.4, ESU5.5, ESU5.6, ESU5.7, ESU5.8, ESU5.9, ESU5.10, ESU5.11, ESU5.12, ESU5.13, and ESU5.14, of which each population was made in 4 replications.Results showed that of 14 populations of goosegrass, 8 populations were “very resistant” and 6 populations were “resistant” to glyphosate. Thus the entire populations have developed to become resistant to glyphosate. Keywords : Distribution, eleusine indica, glyphosate, resistance, rubber estate
