Abstract

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

Abstract

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

Abstract

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.

Abstract

Soybean production is influenced by the variety and nutrients available in the soiland plant roots can absorb. This research means to test the response of severalvarieties of soybean (Glycine max L.Merill) for guano fertilizer. Location of theresearch was conducted in the Tanjung Selamat village, Deli Serdang regency,using a randomized block design of two factors they are varieties (Anjasmoro,Burangrang and Argomulyo ) and guano doses (250, 300, 350, 400 and 450kg/ha). The parameters observed were plant height, branch number produtive,number of pods per sample, the number of filled pods per sample,number ofempty pods per sample, weight of dry seed per sample, weight of dry seed perplot, weight of 100. The results showed that varietie significantly influenced toplant height, branch number produtive, number of pods per sample, the number offilled pods per sample,number of empty pods per sample, weight of dry seed persample, weight of dry seed per plot, weight of 100. Varieties and fertilizertreatment interaction effect was not apparent guano on all parameters.Key word : soybean, variety, guano

The Parameter observedincludes plant hight (cm), diameter of stem (mm), leaf area total (cm2), fresh and dry weight ofcrown (g) fresh and dry weight of root (g). The result of reseach showed that planting mediainfluential significantly on plant height and diameter of stem. Present of leaf fertilizer influentialsignificantly on diameter of stem and dry off root. Interaction between planting media present offertilizer not influential significantly on plant height, diameter of stem, total of broad leaf, fresh anddry weight of crown, fresh and dry off root.Key words : cocoa waste compost, leaf fertilizer, cacao, nursery

Abstract

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.

Abstract

The purpose of the study was to determine the effect of the number of peanut and corn population tothe growth and yield in intercropping pattern system. The research was conducted at LambarVillage Tigapanah District Karo Regency, North Sumatera with the height of ±1200metres abovesea level, began from November 2013 until May 2014. The research was arranged with arandomized block design with two factors. The first factor was peanut population (20x20 cm, 30x20cm, 40x20 cm, 50x20 cm) and the second was corn population (60x20 cm, 70x20 cm, 80x20 cm).The parameters observed were peanut height, number of peanut leaf, corn height, number of cornleaf, number of pod per sample, peanut production per plot, weight of 100 peanut grain, peanut leafarea index, wet weight of corn cob, dry weight of corn cob, and corn production per plot. Theresults showed that corn height, number of corn leaf, peanut production per plot, weight of 100peanut grain, wet weight of corn cob, and peanut leaf area index were significantly affected bypopulation of peanut. Population of corn significantly affected the wet weight of corn cob, dryweight of corn cob, and corn production per plot. Analysis of data showed that the interaction ofpeanut and corn population were founded and significantly affected the corn height, number of cornleaf, and weight of 100 peanut grain.Keywords : peanut, corn, population.
