The Response of Growth and Yield of Four Soybean Varieties (Glycine max L.) to The Shading Levels,The aim of the study was to obtain the effect of soybean seed size on the shading levels for growth and yield of soybean (Glycine max L.) The study was conducted at Tanjung Selamat village at 57 metres above sea level, from April to July 2012. The split plot design was used two treatment, namely shading level a N0 (no shading), N1 (shading 20%), N2 (40% shading), and N3 (60% shading) as main plot and four varieties V1 (Anjasmoro), V2 (Burangrang), V3 (Wilis), and V4 (Rinjani) as sub plot. The results showed that shading level significantly affected germination percentage, plant height 2-5 Weeks After Planted, number of branches, number of chlorophyll, total leaf area, number of fill pods, and production per twelve plants. The soybean varieties significantly affected plant height ages 2-5 Weeks After Planted, number of chlorophyll, number of branches, flower initiation, number of fill pods, production per twelve plants, and weight of 100 seeds. Interaction of two treatments significantly affected production per twelve plants. Keywords: soybean, shade, and varieties

The objective of this research were to find out the influence of gamma ray radiation to mungbean that planted in saline condition, in vegetative and generative phase. This research was conducted in plastic house of Agriculture Faculty, University of North Sumatera, Medan with ± 25 meter altitude above sea level, wich was held in March 2012 to June 2012, using Randomized Block Design, with two factors that were radiation dosages (0, 10, 20 and 30 krad) and NaCl concentrations (0, 2, 4 and 6 g/l). Data were analyzed with ANOVA, and if the ANOVA showed significantly different, the analysis were continued with HSD. The results showed that radiation were significantly influence to plant height (4 and 5 weeks after planted) and harvesting age, salinity were significantly influence to leaf width, ratio of root-canopy dry weight, and root volume, while the interaction of radiation and salinity were not significantly influence to whole parameters. Key word : mungbean, radiation, salinity, production

ABSTRACT One way to effort increase rice production is to expend the cultivation area of rice on saline soil, so it needs to test of some varieties in order the varieties can adaptation. This research aims to obtain varieties of rice (Oryza sativa L.) that can be adapted to saline soil. The research was conducted in the Desa Serdang, North Sumatera at ± 1 m altitude above sea level and 1.5 – 2 km from the beach. The research was carried out in May until October 2011. The design of the experiment was randomized block design with 18 varieties that carried out a preliminary test before, in order get 5 varieties that can adapted to saline soil. The results showed that 5 varieties can adapted to the saline soil is Banyuasin, Siakraya, Martapura, Dendang, and Margasari. Martapura was better than the other varieties on plant height, number of tillers, number of productive tillers, panicle length, wet weight of roots and grain productions parameter. Key words : rice, varieties, saline

The Ability of Parasitoid Apanteles flavipes Cam. (Hymenoptera: Braconidae) on Sugarcane Stem Borer (Chilo sacchariphagus Boj.) (Lepidoptera: Pyralidae) in the Laboratory, The sugarcane stem borer Chilo sacchariphagus Boj. (Lepidoptera: Pyralidae) is one of pest that attack sugarcane crop in North Sumatera. The objectives of this research were to study the ability of parasitoid Apanteles flavipes Cam. (Hymenoptera: Braconidae) to control C. sacchariphagus. The research was conducted at the Laboratory of Sugarcane Research and Development Sei Semayang, Binjai, Medan, North Sumatera from Mei to July 2012. This method used Randomized Complete Design Factorial with two factors. The first factor was age of A. flavipes (control, 0, 1, 2, 3, 4 days) and the second factor was number of C. sacchariphagus (1, 3, 5, 7 larvae) with three replications. The results showed that the percentage of parasitation depend on age of A. flavipes and number of C. sacchariphagus. The result showed that the highest percentage of parasitation (48.02%) on 0 day A. flavipes and the lowest (11,11%) on 4 days A. flavipes. The highest percentage of parasitation (61,11%) in number of host was 1 larvae C. sacchariphagus and the lowest (9,53%) in 7 larvae C. sacchariphagus. Sex ratio of male and female was 1: 1.99.

Puar tenangau is a herbal plant of Zingeberaceae that from Thailand. The Plant has a big potential as pharmacy and traditional medicines, but the spread of this plant was unknown well in Indonesia even so needed a conservation for this plant. In vitro conservation is a one of alternative. In in vitro method, adding plant growth regulator is needed like Auxine and cytokinine. Napthtalen-3-Acetid is kind of auxine that good to root growth and Benzil amino purin is kind of cytokinin to shoot growth. The research aimed to know the influence of Benzylamino purine (BAP) and Napthtalen-3-acetid acid (NAA) concentration on the growth of puar tenangau.The research was carried out in the Tissue Culture Laboratory, Agriculture’s Faculty of Nort Sumatera University from March to June 2012. This research used Completely Randomized Design with two factors. First factor was BAP concentration consist of four levels:0 mg/l; 2 mg/l; 4 mg/l; 6 mg/l. The second factor was NAA concentration consist of three levels are 0 mg/l; 1.5 mg/l; 3 mg/l. The results showed that BAP concentration give effect significantly only on leaves number in 12 weeks after planting, but it have no effect significantly on the percent of living explant, plantlet height, leaves number on 4 and 8 weeks after planting. NAA and interaction of BAP and NAA have no effect significantly to living explant, plantlet height, leaves number on 4,8 and 12 weeks after planting. Keywords: puar tenangau, BAP,NAA, In vitro.

ABSTRACT Growth of plant is affected by some factors; among other things are plant media and auxin application. A research had been conducted at Pasar II Setiabudi, Kelurahan Tanjung Sari, Medan (± 25 m asl) in March – August 2012. The objective of the research was to know response of plant media and auxin naphtalene acetic acid application on the growth of sugar palm seed. The research that use Randomized Block Design with two factor that plant media of (top soil + sand + compost), (top soil + husk charcoal + compost), (top soil + sand + husk charcoal + compost) and auxin application were of 0 ppm, 50 ppm, 100 ppm and 150 ppm. The parameters observed were increase seed height, leaf sum, leaf klorofil and steam diameter. The result of research showed that the response plant media and auxin naphtalene acetic acid application on sugar palm nursery with interaction between plant media and auxsin application were not significantly to all the parameters observed. Keywords : plant media, auxsin application, sugar palm

The aim of the research was to studyseed viability of rosela (Hibiscus sabdariffa L.) during 3 months storage on various levels of initial seed moisture content and storage seed packaging. It was conducted in the Laboratory of Seed Technology, Faculty of Agriculture USU about 25 m sea level rise on Mei to September 2012 by using randomized block design with two factors. The first factor was various levels of initial moisture content(7%, 9% and 11%) and the second one was storage seed packaging(aluminium foil, polyethylene plastic and paper). Variables measured include moisture content, germination rate, grow potential, germination percentage and vigor index. The results showed that initial seed moisture contentshowed only significant effects on moisture content and storage seed packaging showed significant effects on moisture content, grow potential, and germination percentage. Interaction of both treatments showed non significant effect on all parameters. Key words : Rosela seed, moisture content, storage seed packaging and seed viability.
