Soybean crop productivity on saline land affected by the input that is given to the provisionof mycorrhizal plants. For which a research field trials have been conducted in the village ofTanjung Rejo District Percut Sei Tuan Deli Serdang regency (± 1.5 m asl.) In May-July 2012.Experimental was conducted using a factorial randomized block design that is mycorrhizalwith standard treatment (M0 = No provision of mycorrhizal and mycorrhizal granting M2 =10 g / plant), the treatment was repeated six times. The data were analyzed using variance(ANOVA) and continued with HSD.The analysis of data showed that administration ofmycorrhizae improve plant height at age 5 MST, the number of branches, number of podsand cropping, as well as accelerate the age of flowering plants.Key words: salinity, mycorrhizal

Generative propagation of mucuna produces low germination percentage and requires long time togerminate due to seed dormancy which is caused by the seed coat that is impermiable to oxygenand/or water. This study is aimed to find out the effect of the treatment of chemical compund ondormancy realease of mucuna seed. This study was held in the Laboratory of Plant BreedingAssociation at Agriculture Faculty of University of North Sumatera (USU) (± 25 m asl) from Mayto June 2013 by using random block design with 8 treatments. Each treatment was replicated 3times. The treatments were without treatment (A1), the seed coat scarification and soaking in waterfor 30 minutes (A2), soaking in 1% of H2SO4 for 10 minutes (A3), soaking in 1% of H2SO4 for 15minutes (A4), soaking in 1% of KNO3 for 12 h ours (A5), soaking in 1% of KNO3 for 24 hours(A6), soaking in 300ppm of GA3 for 3 hours (A7), and soaking in 300ppm of GA3 for 5 hours(A8). The parameters were moisture (%), germination capacity (%), germination speed (% / etmal),dormancy intensity (%). The results show that dormancy release has significant effect on moisture(%), germination capacity (%), germination speed (%/etmmal), and dormancy intensity (%). Thetreatment of soaking in 1% of H2SO4 for 10 minutes (A3), soaking in 1% of KNO3 for 24 hours(A6), and soaking in 300 ppm of GA3 for 5 hours (A8) were the treaments that were able to releaseMucuna seed dormancy with germination capacity >80%; treatments A3 and A6 each produces91.67% and A8 produces 86.67%. The best dormancy release was produced by treatment A6 that issoaking in 1% of KNO3 for 24 hours compared with H2SO4 and GA3.Keywords: Mucuna, dormancy, dormancy breaking

The objectives of this research was to produce the large seed size of several black soybean varietiesselected based on seed size. The research was conducted on Pasar 1 Tanjung Sari, District MedanSelayang, Medan with a height of ± 25 meter above sea levelon. It was started on Februari until Mei2013 by using Split Plot Design of Two Factors which are varieties and seed size with 4replications. Varieties was researched are Detam1, Detam2, Cikuray and Mallika. The seed sizewas researched are large seed size and small seed size. The result showed that Mallika varietiesshowed the best growth on plant height (34,85 cm) and number of branches on main branches (4,33branches ). The highest production is Detam1 (32,65 g) in production per plant parameter. Theplants from the large seed size showed the best growth on plant height (31,91 cm) and number ofbranches (3,88 branches). The plants from the small seed size produced more medium seed sizewith range 41.92 % - 58.88 %. The plants from the large seed size produced more medium seed sizewith range 41.07 % - 51.55 % except on Detam 2 which from the large seed size produced morelarge seed size. Interaction between varieties and seed size that showed the best growth is oninteraction between Detam 2 varieties with large seed size (V2U2) on plant height parameter (20,35cm). interaction between Detam 1 with small seed size (V1U1) showed the best productioncompare with the others on production per plot (535 g).Key words : black soybean, varieties, seed size

The aim of the research was to evaluate the response of latex production at various times application in multiple clones rubber plant to giving several sources hormone ethylene. The experiment was conducted in October 2013 to March 2014 in Sungei Putih Rubber Research Institute, Galang Subdistrict , Deli Serdang regency. Three-Stage Nested Design was applied with three replications. The first step was time application, i.e., a first application, a second application, a third application, and a fourth application, the second step was clones treatment, i.e., IRR 118 clones, PB 260 clones, IRR 42 clones, IRR 39 clones and the third step was stimulants treatment, i.e., without stimulants, ethrel, SP1, banana peel extract and extract of pineapple skin. Observed parameters was the latex volume. The study showed that time application had no significant increased on latex production, and clones treatment at various times application had no significant to produce on latex production, whereas stimulant treatment in multiple clones at various times application significantly increased latex production. IRR 39 clones were clones that experienced the highest increase in producing due to the provision treatment of stimulants. SP1 was a stimulant that increases the production of the highest latex. Ethrel, banana peel extract was a stimulant that can increase the production of latex higher than without stimulants. Pineapple peel extract resulted in clumping of latex flow on tapping grooves and a low yield of latex productionKeywords: Latex Production, Time Applications, Clones, Stimulants

Kedelai merupakan komoditas pangan penting karena banyak dibutuhkan untuk bahan pangan, pakan ternak dan industri. Kebutuhan kedelai mencapai 2 juta ton, sedangkan produksi hanya 1,2 jt ton. Untuk memenuhi kebutuhan tersebut dilakukan usaha intensifikasi dan ekstensifikasi. Usaha ekstensifikasi dengan memanfaatkan tanah-tanah marginal. Salah satu tanah marginal adalah tanah salin. Di indonesia diperkirakan luas lahan salin 440.300 ha. Tujuan penelitian ini adalah untuk mengevaluasi karakter pertumbuhan dan produksi tanaman kedelai hasil persilangan pada tanah salin. Penelitian ini dilakukan di rumah plastik buatan dalam rumah kasa Fakultas Pertanian USU (± 25 meter dpl) pada bulan April sampai bulan Agustus 2015. Benih F2 diperoleh dari penelitian sebelumnya dengan menggunakan benih hasil persilangan varietas anjasmoro dengan genotipa kedelai tahan salin. Hasil penelitian menunjukkan bahwa untuk karakter tinggi tanaman, jumlah daun, jumlah cabang, umur berbunga, jumlah polong berisi, jumlah polong hampa, bobot biji, jumlah biji, dan umur panen tidak bersidtribusi normal, memiliki tingkat segregasi yang tinggi dengan adanya pengaruh gen aditif epistasis dan masih dipengaruhi oleh banyak gen.
