This research was conducted in Pembangunan street Subdistrict Medan Selayang, began from May to September 2016. This research used factorial randomized block design with two factors. The first factor was lady finger varieties were Red burgundy and Garibar. The second factor was application of organic fertilizer with four treatment (without organis fertilizer, compost 22,5g/10kg soil, vermicompost 30g/10kg soil, and chicken manure 75g/10kg soil). Garibar variety different on plant length, number of leaves, number of fruit, and fruit weight with Red burgundy. Chicken manure treatment can increase plant length, number of leaves, number of fruit, and fruit weight. Interaction between varieties and organic fertilizer treatment can increase plant length.

Elaeidobius kamerunicus introduced to Indonesia in Palm Research Center, Marihat. It is one pollinator to pollinate palm. Genetic changes in these insects cause a decline in palm oil production. The purpose of this study to determine the genetic diversity of it based molecular analysis techniques AFLP using three primers. Primers used are HEX (EcoR1 ACA - Mse1 CTT), FAM (EcoR1 AGG - Mse1 CAG) and FAM (EcoR1 AGG - Mse1 CTT). Analysis of genetic diversity using the MEGA program version 6. Phylogenetic tree using 'Neighbor-Joining Tree'. AFLP amplification product to 42 samples of genomic it and 3 Sitophilus oryzae genomic sample as a control showed a high diversity. The analysis showed that itgenetically grouped separately with S. oryzae. It contained in districts in North Sumatra has two large groups : group A1 and A2. Group A1 consisting of Ajamu, Bah Birong Ulu, Binanga, Bukit Sentang, Marihat, Padang Madarsah and PT. TPS Sibolga while the Group A2 consists of two regions, namely Marihat and Bah Birong Ulu while S. oryzae contained in Medan form their own group.

Pengembangan bawang merah di tanah pasir kuarsa pedalaman di luar musim atau musim hujan merupakan hal baru. Tujuan penelitian ini mendapatkan varietas bawang merah yang adaptif ditinjau dari parameter pertumbuhan, produksi, dan kualitas. Rancangan percobaan menggunakan RAK4x3 (Rancangan Acak Kelompok) dengan 4 perlakuan varietas (Maja Cipanas, Tajuk, Bauji dan Bima Brebes), setiap perlakuan diulang tiga kali. Hasil penelitian menunjukkan bahwa bobot isi tanah meningkat dengan makin dalamnya tanah, namun kadar air tanah sebaliknya makin menurun. Pada parameter pertumbuhan nampaknya Tajuk terbaik dan berbeda nyata dibandingkan Bima Brebes. Pada parameter produksi ternyata Maja Cipanas, Bauji dan Bima Brebes memiliki berat 10 g lebih, sedangkan Tajuk hanya 6,79 g. Produksi varietas Bauji adalah terbaik dengan produksi kering sebesar 22,4 t/ha meskipun tidak berbeda nyata dengan Maja Cipanas 18,49 t/ha. Pada parameter kualitas maka Bima Brebes cukup baik ditinjau dari parameter kekerasan umbi dan Total Padatan Terlarut (TPT) berturut-turut 4,9 kg/cm2 dan 16,42 %.

This experiment aimed to determine the growth response and the protein content of antioxidants in the seeds melinjo age of 3 months after administration of the compound NaCl to salt stress condition. Research using a completely randomized design (CRD) with one factor different concentrations of NaCl, 0 mM NaCl; 25 mM NaCl; 50 mM NaCl; 75 mM NaCl and 100 mM NaCl. The parameters observed plant growth, total soluble protein content, activity of antioxidant proteins and protein banding pattern. The results showed that the growth parameters of seedlings melinjo showed no significant with the provision of NaCl except in wet weight, dry weight and chlorophyll content in total, while the total content of protein and antioxidant activity decreased on treatment of 25 and 50 mM NaCl concentration, then climbed back on treatment 75 and 100 mM, namely the 100 mM obtained total protein content of 3.33 mg / g, 78.7% ABTS reduction activity with IC50 values of 0.8 mg / mL). The pattern of protein bands showed different band patterns in the treatment of 100 NaCl. Keywords: Melinjo, NaCl, Protein, Antioxidant Activity.

Land evaluation is estimation process of the potensial land for a variety of alternative uses optimally by considering physical and socioeconomic factors as well as conservation of environmental resources for sustainable use. This study aimed to evaluate the suitability of rice paddy (Oryza sativa L.) in Village Sukorejo Subdistric Sei Balai Distric Batubara. It can be obtained 2 (two) Land Mapping Unit (SPL) which is determined base on the overlay result from the map of topography, map of soil types and map of land use with scale of 1 : 20.000 that is Sawah Ultisol SPL 1A and 1B and Sawah Inceptisol SPL 2A and 2B. This study used survey method and the class assessment of land suitability was done by matching based on criteria astablished by Peraturan Mentri Pertanian No.79 (2013). The results showed that the land suitability classes of actual rice paddy (Oryza sativa L.) in SPL 1A, 1B and 2A is Marginally Suitable/ S3nrxs by a nutrient retention and sulfidic material barrier factor while in SPL 2B is Marginally Suitable/S3nr by a nutrient retention barrier factor. The land suitability calasses potential rice paddy (Oryza sativa L.) for l SPL (1A, 1B dan 2A) is suitable/ S2nrxs by a nutrient retention and sulfidic material barrier factor while in SPL 2B is suitable/ S2nr by a nutrient retention barrier factor.

Classification of soil is a process to select the soil according to the characteristic and their ability. Classification gives a description of the physical properties, chemistry, and minerals of land owned which can then be used as a basis for management for land users. The study aim to classify the soils on orders, sub orders, great groups and sub groups. The location at Village Sukorejo Subdistrict Sei Balai District Batubara, that start from September 2016 until Januari, 2017. Soil morphology was description of soil profiles to know soil properties, horizons and diagnostic horizon. Soil samples were taken from each horizon for laboratory analysis of soil texture, bulk density, pH (H2O), pH (KCl), P2O5, organic carbon, exchangeable cations (Ca2+, Mg2+, K+, Na+), Total Fe, Al can be exchange, base saturation and cation exchange capacity (CEC) in Socfindo, Asian Agri, and Chemistry and Soil Fertility Laboratories Agriculture Faculty University of North Sumatera. The results shows that type of soil SPL 1A and 1B are Ultisols, Aquults, Albaquults, dan Typic Albaquults. For SPL 2A and 2B are Inceptisols, Aquepts, Endoaquepts, dan Aquandic Endoaquepts. Keywords : Lowland rice, soil classification, soil taxonomy 2014

The cocoa farmers mostly practice conventional pest control that can be harmful to the environment, therefore integrated pest management has been developed. This research aimed to know diversity of insects in cocoa plantations affected by integrated pest management (IPM) and conventional (non IPM) techniques. This research was conducted in two villages in Biru-Biru District, Deli Serdang Regency and in Plant Pests Laboratory, Faculty of Agriculture, Universitas Sumatera Utara, Medan from June until September 2016. This research used four insect traps (sweep net, pitfall trap, light trap, and yellow trap), and repeated five times. The results showed that insects caught on cocoa plantations with IPM were 12 orders and 44 families, the highest relative density value was 27.49%, the lowest was 0.07%, the index value of insect diversity Shannon-Weiner (H') was 2.90 (moderate) and the index value of insect evenness (E) was 0.76 (high) whereas on cocoa plantations with non IPM were 10 Orders and 39 families with the highest relative density value was 25.27%, the lowest was 0.10%, the index value of insect diversity Shannon-Weiner (H') was 2.76 (moderate) and the index value of insect evenness (E) was 0.75 (high). Keywords: biodiversity, cocoa, insects, integrated pest management
