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.

The use of antagonism fungus of Trichoderma sp. and Gliocladium sp. for controlling wilt(Fusarium oxysporum) in red onion plants. The aim of the research was to know the effectiviness ofantagonism fungus of Trichoderma sp. and Gliocladium sp. in controlling wilt in red onion plants.The research used non-factorial RAK (random group design) with eight treatments: control, 10grams of F. oxysporum, 12 grams of Trichoderma sp., 18 grams of Trichoderma sp., 24 grams ofTrichoderma sp., and 12 grams of Gliocladium sp., 18 grams of Gliocladium sp., 24 grams ofGliocladium sp., and three repetitions. The result showed that the worst-highest disease was incontrol with 10 grams of F. oxysporum (2.60%) and the lowest disease was in control, 18 grams ofTrichoderma sp., 24 grams of Trichoderma sp., 18 grams of Gliocladium sp., and 24 grams ofGliocladium sp. (0.71%). The accident of the highest disease was in 10 grams of F. oxysporum(5.01%) and the lowest was in control, 18 grams of Trichoderma sp., 24 grams of Trichoderma sp.,18 grams of Gliocladium sp., and 24 grams of Gliocladium sp. (0.71%). The largest number ofleaves was in 24 grams of Trichoderma sp. (36 leaves), and the smallest was in 10 grams of F.oxysporum (29 leaves). The highest plants was in 24 grams of Gliocladium sp. (40.20 cm) and thelowest in 10 grams of F. oxysporum (37.26 cm). The largest number of F. oxysporum colonies in 10grams of F. oxysporum (8.86%). The highest production was in 24 grams of Trichoderma sp. (2.34tons/ha) and the lowest in 10 grams of F. oxysporum (1.56 tons/ha). The test of antagonism fungusof Trichoderma sp. and Gliocladium sp. on F. oxysporum indicates that the growth of both types ofantagonism is faster so that F. oxysporum tends to keep away from antagonism in the medium of thelaboratory.Keywords: Trichoderma sp., Gliocladium sp., Fusarium oxysporum, antagonism

The aim of the research was to evaluated the effect of potassium fertilizer (K) andthe planting distance on the growth and yield of onion (Allium ascalonicum L.)varieties Tuktuk. The research used Randomized Block Design with two-factors.The first factor was the doses of potasium fertilizer (KCl) with four levels e.g : K0= without KCl (control), K1=10 g KCl/m², K2= 20 g KCl/m² and K3 = 30 gKCl/m². The second factor was planting distance with three levels e.g : J1 = 10x10cm, J2 = 10 x 15 cm and J3 = 10 x 20 cm. The results showed that the diameterof tubers, wet weight of tubers per sample and dry weight of tubers per samplewere significantly affected by potasium fertilizers. The higest of diameter oftubers, wet weight of tubers per sample and dry weight of tubers per sample wereproduced by K2, whistling of each were 3,72 cm, 18,69 g and 5,61 g, but plantheight and leafs number were unsignificantly. Where as, plant height weresignifcantly affacted by planting distance were prouced by J2 e.g 16,01 cm, butleafs of number, diameter of tubers, wet weight of tubers per sample and dryweight of tubers per sample unsignificantly. Interaction of potasiumfertilizer and planting distance significantly affected the wet weight oftubers per plot and dry weight of tubers per plot. The higest of wetweight of tubers per plot and dry weight of tubers per plot wereproduce by K2J1 were 1,34 kg and 0,40 kg.__________________________________________________________________Key words: onion, potassium fertilizer and planting distance

Peanut is one of food plant that has high economical value because of its nutrient content especiallyprotein and fat. The other alternative to increase peanut productivity were application of Tithoniadiversifolia organic matter and SP-36 fertilizer. The aim of the study was to obtain the effect ofapplication Tithonia diversifolia organic matter and SP-36 fertilizer on growth and yield of peanut.The study was conducted at Jl. Pasar I Tanjung Sari, Medan with the height 25 metres abovesea level from May to September 2012. The factorial randomized block design was used twofactors, namely Tithonia diversifolia organic matter (0, 3, 6 and 9 ton/ha) and SP-36 (0, 25, 50, 75and 100 kg/ha). The parameters observed were number of ginofor per sample, number of filled podsper sample, number of empty pods per sample, weight of pods per sample, yield per plot and 100grain weight. The results showed that the Tithonia diversifolia organic matter had no significanteffect on all parameters and SP-36 fertilizer significantly affected 100 grain weight. Interaction ofthat treatment had no significant effect on all parameters.Key words : peanut, Tithonia diversifolia , organic matter, SP-36 fertilizer

The objective of this research was study the role of silicate material and phosphat fertilizer inimproving soil chemical charachteristics and plant growth. Andisols material was taken fromagriculture area with horticulture commodity in Kuta Rakyat Village, Naman Teran Subdistrict,Karo Regency. This research used factorial blocky randomized design with 3 block and 2 factors.The silicate material were consisted of four kind are : B0 (control), B1 (Agrosil), B2 (coarse grass),B3 (straw rice). The treatment of phosphate fertilizer consisted of four levels, namely : F0 (0 ppm P),F1 (100 ppm P), F2 (200 ppm P), and F3 (300 ppm P). Silicate material was incubated for 45 daysand then applied P fertilizer. The plant kept until vegatative phase in green house. The result of thisresearch showed that the affect of material silicate of coarse grass was very good in increasing Puptake,diameter of stem, dry weight root,dry weight crown, and height plant. And then straw rice isvery good in decrease P retention and Agrosil is very good in increase SiO2 available. The effect ofP fertilizer is not significant while the effect of interaction of silicate material and P fertilizer onlysignificant in hight plant.Keywords : Andisols, silicate material, and phosphate
