The aims of this research to know the growth and production of corn (Zea mays L.) Pioneer-12Variety effect of pruning leaves and giving NPKMg fertilizer. This research is implemented ontrying field Tumpatan Nibung village, Batang Kuis, Sumatera Utara, Medan on April 2012 andfinished on Juli 2012. The research was done by using Completely Randomized Design (RAK)factorial consist of two factors treatment. The first factor is pruning with three levels, M0 (withoutpruning), M1 (prune two leaves) and M2 (prune three leaves). The second factor is NPKMgfertilization with four levels, yaitu P0 (0 kg/Ha), P1 (250 kg/Ha), P2 (500 kg/Ha) dan P3 (750kg/Ha). Result of the research show that the pruning treatment effects real against flowering,harvest, weight of dry shelled per sample and hundred weight of seed grain but it does not effectreal against plant height and harvest index. The fertilization treatment effects real against plantheight, flowering, harvest, weight of dry shelled per sample and hundred weight of seed grain but it

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

Response of growth of deli tobacco (Nicotiana tabaccum (L.)) on some kind of lime and soil types in North Sumatera. Deli tobacco is variety of tobacco that is used as world top quality wrapper of cigar . But, in last years production of deli tobacco had been decreasing because of land degradation. Consequently, it is important to develop deli tobacco plantation to another soil types that is combine by giving some kind of lime. The aim of this research was to examine growth of deli tobacco (Nicotiana tabaccum (L.)) on some kind of lime and soil types in Noerth Sumatera. The research was conducted in the land of the Research Center of Deli Tobacco (BPTD) Sampali PTPN II, starting from February to May 2012, using a randomized block design (RBD) factorial with two factors and three replications . The first factor is soil types (alluvial, andosol, hidromorf, ultisol). The second factor is the kind of lime (dolomite, calsit, kaptan). The results showed that soil types significantly affect on plant height, diameter of stem, number of leave, thick leaf sand, 1 foot thick leaves, long leaves sand, 1 foot long leaves, leaf width sand, and 1 foot wide leaves. Kind of Lime and the interaction between soil and lime is not significantly affect for all parameter observed. Keywords: soil, lime, Tobacco Deli.

ABSTRACTResponse in Growth and Yield of Shallot (Allium ascalonicum L.) on Giving Vermicompost andRabbit Urine. The use of chemical fertilizersis an alternative that is often selected farmers toincrease the production of shallot. Because of that giving of vermicompost and rabbit urine is expectedto replace the role of chemical fertilizers in increasing the growth and production of shallot. Thisresearch had been conducted at Farm Resident on street Pasar I number 89 Tanjung Sari, Medanfrom May until July 2013 using factorial randomized block design with two factor, i.e. dose ofvermicompost (0, 15, 30 and 45 g vermicompost/plant) and dose of rabbit urine (0, 125 and 250 cc/l).Parameter observed were plant height, tillers number per clump, leaves number per clump, clovenumber per sample, wet weight tuber per sample, wet weight tuber per plot, dry weight tuber persample, and dry weight tuber per plot. The result showed that vermicompost treatment not significantlyaffected all of parameter observed. Rabbit urine treatment increase plant height, tillers number perclump, clove number per sample, wet weight tuber per sample, wet weight tuber per plot, dry weighttuber per sample, and dry weight tuber per plot. The treatment interaction significantly effected onparameters tillers number per clump and clove number per sample. The best result were showed byvermicompost treatment 15 g/plant and rabbit urine treatment 250 cc/l.Keywords : Vermicompost, rabbit urine, shallot

The purpose of the study was to determine the effect of paclobutrazol and potassium fertilizer onthe growth and yield of peanuts. The research was conducted at Pasar I Tanjung Sari street, Medanwith the height of 25 metres above sea level, began from May until October 2013. The research wasarranged with a randomized block design with two factors. The first factor was concentration ofpaclobutrazol ( 0 ; 75 ppm ; 150 ppm and 225 ppm ) and the second was dose of KCl ( 0; 0.15 g ;0.3 g and 0.45 g ) . The parameters observed were plant height, number of ginofor, number ofproductive branches, number of unproductive branches, days to flowering, harvesting, pod weightper sample, number of filled pods per sample, number of empty pods per sample, weight of grainper sample, weight of grain per plot and weight of 100 grains. The results showed that plant height,number of ginofor, number of productive branches, days to flowering, pod weight per sample,number of filled pods per sample, weight of grain per sample, weight of grain per plot, and weightof 100 grains were significantly affected by paclobutrazol concentration. However all parametersobserved were unsignificantly affected by dose of KCl. There was also no interaction betweenpaclobutrazol concentration and dose of KCl .Key words : peanuts , paclobutrazol , KCl fertilizer.
