The aim of this research was study the effect of soil types and compost to provide nutrients nitrogen and growth of corn plant. Nitrogen is an essential nutrient by the main source of organic material from corn required with high levels at the age of four weeks to optimum product in soils low levels of nitrogen. For it has done a research in the field screen Agriculture Faculty University of Sumatera Utara (± 25 m above sea level) in June-August 2012 by using a factorial Randomized Block Design in two factors: types of soils were entisols, inceptisol and ultisol and compost were control, straw compost + chicken manure, straw compost + cocoa fod compost, cocoa fod compost + chicken manure. Parameters measured were soil pH, soil C-organic, soil N-total, ratio of C/N soil, plant height, plant dry weight, N plant level and N-plant uptake.The results showed that the combination of various organic matter on the three soil types significantly affect to the C-organic, N-total soil, plant height, plant dry weight and N-plant uptake.

The objective of the research is to know the tolerance of M3 soybean generation radiated by gamma ray to salinity. The research was conducted on the Experimental Farm Faculty of Agriculture, University of North Sumatra,, from December 2011 – March 2012. Randomized block design was used with two treatments i.e : population of M3 soybean (0, 10, 20, 30 krad per plant) and NaCl concentration (0, 1500, 3000, 4500 ppm). Parameters measured were plant germination, viability, high of plant, the number of node per plant, the number of branch, root longth, weigh of dry root, weigh of dry leaves, the number of pods per plant, the number of empty pods per plant and weigh of 100 seed. M3 soybeans showed significant diffrent on root longth and weigh of dry root. NaCl concentration affect were significantly to plant germination and viability.The interaction between population M3 soybeans and NaCl concentration were significantly to the number of node per plant, the number of branch, weigh of dry leaves, the number of pods per plant, the number of empty pods per plant and weigh of 100 seed. Key words: tolerance, salinity, M3 generation, soybean

Response on Growth and Yield of Maize (Zea mays L.) Hybrid and Nonhybrid Varieties by Giving Bokashi and Potassium Fertilizer, a research had been conducted at experimental field of Balai Benih Induk Palawija, Tanjung Selamat, Kabupaten Deli Serdang, North Sumatera, Medan (± 57 m asl) in May – August 2012. This research was arranged using randomized block design with treatment; nonhybrid varieties (Bisma) and hybrid varieties (SHS-4), bokashi with level 0 and 180 g/plant, potassium fertilizer with level 0, 1.8, and 3.6 g/plant, treatment was replicated three times, the data were analyzed with ANOVA and continued with HSD. The results showed that potassium fertilizer with 0 grams of Bokashi reached the maximum dose at 2.2 g/plant to nonhybrid varieties (Bisma) and hybrid varieties (SHS-4), while the addition of 180 g bokashi, potassium fertilizer reaches a maximum dose at 1.4 g/plant to nonhybrid varieties (Bisma) and 1.2 g/plant hybrid varieties (SHS-4) for a weight of 100 seeds. In the production of dry shelled potassium fertilizer by 180 g bokashi, nonhybrid varieties (Bisma) reached a maximum dose at 1.9 g/plant and 2.5 g/plant to hybrid varieties (SHS-4). Keywords: nonhybrid, hybrid, bokashi, potassium

The source of liquid waste of tapioca industry from leaching and evaporation. Normally that liquid waste contents rough and soft of suspension solid and organic matter. Accumulation continuously of liquid waste of tapioca industry cause bad taste and odor so can destroy environment. The research executed on 5 tapioka factory at watershed Padang area and aroundabout used a survey method. The research was conducted by water sampling at 3-5 outlets, first from point of exile source of liquid waste to mixed at stream of river-bed. Water sampling used intergrating depth system method, in this researh at water surface of river stream. Water samples were taken three (3) replications for each outlet. Parameters were measured pH, TSS TDS, BOD, COD and velocity of water. The research result to point at stream river waste of tapioca factory outlet PT. Serasi Jaya to point at increase value at some parameters to exceed standard quality class that on pH, TSS, and COD parameters each 4,23, 8,80 mg/L, and 137 mg/L. At stream river water waste of tapioca factory outlet PT. Sumatera Telaga Tapioka find some parameters to exceed standard quality class on parameters value pH, TSS, COD each 4,48, 79,3 mg/L, 1045,2 mg/L. At stream river water waste of tapioca factory outlet PT. Deli Sari Murni find some parameters to exceed standart quality class on TSS and COD parameters each 84,67 mg/L and 167,27 mg/L.

Strain Selection of Soybean ( Glycine max (L) Merril) of F3 Generation on Saline Soil. Salinity isone of the most serious and widespread agricultural problems resulting in losses of yield. Generally,as land is more intensively cultivated, the salinity problem becomes more severe. A highconcentration of NaCl greatly reduces growth of both the shoot and the root. One strategy availableto cope with saline soil is to choose salt-tolerance crops or to select salt-tolerance cultivars within acrop. This research aims to select the soybean that can grow and has a higher production on salinesoil of F3 generation. This research was conducted in the experiment area at Desa Tanjung Rejo,subdistrict of Percut Sei Tuan, Regenecy of Deli Serdang in the elevation of 1.5 m on above sealevel since Apryl 2012 up to Juny 2012. The experiment design applied in this research is a crosssection analysis that consist of 1 variety, and the applied methot is a F3 generation pedigreeselection, the population is sample, the number of live plant is 137 of 2118. The selected plant isbased on the grain production per plant for 39 plants. Based on the results of research indicates thatbased on the highest weight of seed per plant is 4.9 g on the plant number 1305.2.20 and the lowestproduction is 0.2 g on the plant number 88.5.10 and 88.5.11. The component of production that hasa direct influence to the grain production per plant is the number of branch, age of flowering,number of pod and number of pods contain. Component of production that giving the highest directinfluence is the number of pod contain for 0.832.Keywords : species, soybean, selection, saline soil.

Farm waste recycling have a role in prevent cause of environment pollute, and in other side canincrease of plant production. One thing which real enough that a lot of farm waste can changebecame organic fertilizer. This reasearch is proposed to find out effect of growth and productionresponse of mustard ( Brassica juncea L. ) as guano and rabbit urine given. The research startedfrom november 2011 until january 2012. The design use randomized block design factorial with 2aspect. The first aspect is guano consist of four stages those are G0 ( 0 g/plant ), G1 ( 4 g/plant ), G2( 8 g/plant ), G3 ( 12 g/plant ). The second factor is rabbit urine consist four stages those are U0 ( 0ml/L water ), U1 ( 20 ml/L water ), U2 ( 40 ml/L water ), U3 ( 60 ml/L water ). Guano givenperform real effect to plant height, number of leaf, leaf area, fresh weight per plant, dry weight perplant, production per plot, but not gave any influenced to production per hectare and harvest index.Rabbit urine given perform real effect to plant height, number of leaf, leaf area, fresh weight perplant, dry weight per plant, production per plot, but not gave any influenced to plant height at 2MST, number of leaf 2 MST, production per hectare and harvest index.
