Abstract

Corn is the third plant of food after wheat and rice. To increasing of productionneeded to use hybrid and nonhybrid variety, with organic and unorganic fertilizer. Theobjective of this research was to evaluate the influence of bokashi and NPK fertilizer ongrowth and yield some maize varieties.The research was carried out in the UPT Balai BenihInduk Palawija Tanjung Selamat, Deli Serdang. This research used Randomized BlockDesign. Two varieties of maize (Bisma and SHS-4), two levels of bokashi (0 and 180g/plant), and three dosages of NPK (4,2 ; 8,4 ; 16,8 g/plant) were used in the experimentwith three replications. The results showed that varieties were significantly different toparameters plant height and numbers of leaf. Bokashi treatment have no significant effectto all parameters. NPK treatment were significant to parameter numbers of leaf at 6 dan 7week after planted. The combination between varieties and bokashi, varieties dan NPK,bokashi and NPK, and combination of varieties, bokashi and NPK have no significanteffect to all parameters.Key words : Variety, Bokashi, NPK Fertilizer

Abstract

Arnen Pasaribu, Test of Rice Varieties (Oryza sativa L.) and Fertilizing of Potassium (KCl) toIncrease Production and The Lodging Resistance. Ir. E.H. Kardhinata, M,Sc. as chairman of thecommision of advisors and members Ir. M.K. Bangun, MS. The aim of the research to get ricevarieties and the best dosage of potassium to increase production and the straw strenght.Randomized block designfactorial was used in this research. The first factors were the varieties(Ciherang, Inpari I, Mekongga and Cibogo) and second factors were dossages of potassium (0,50, 100, and 150 kg/ha). The treatments was used three replications. The parameter wichobserved are height of plant, straw strength, straw diameters, dry weight, straw thickness,panicle length, number of productive tillers, percentage of grains per penicle, percentage ofempty grains, the weight of 1000 seeds, weight of grains perplot, lodging index and hertability.The result of this experiment showed that weight of grains Ciherang is better than the others, themaximum dosages of potassium were 85.07 kg/ha; 103.35kg/ha and66.67 kg/ha for Ciherang,Mekongga and Cibogo but relation of potassium Inpari I showed linear positive. Interractions ofvariety and potassium showed significantly diffrence on height of plant at 3 week after plantedand weight of grains.Key words : Rice, Varieties, Potassium fertilizer.

Hybrid and Nonhybrid Varieties by Phosphate Fertilizer and Bokashi Application.The goal of this research is to know the effect of phosphate fertilizer and bokashi to growth and yield maize  (Zea mays L.) hybrid and nonhybrid varieties.Therefore, a research had been conducted at experimental field of BBI Palawija, Tanjung Selamat, District of Deli Serdang (± 57 m asl) on May – August  2012. This research was arranged using Randomized Block Design, with the first factor is two maize varieties, Bisma and SHS 4. The second factor is concentrate of Phosphate fertilizer with three degrees, 2 g, 4 g and 6 g. The third factor is bokashi with two degrees, 0 g and 180 g, three replications was used to the treatments. Data were analyzed with ANOVA and continued with HSD. The results showed that varieties were significantly different to plant height, leaf number, male flowering time, female flowering time, harvesting time, kernel number per ear and yield of sample. Phosphate fertilizer  were  significantly effect to leaf number at 2 weeks planted, harvesting time, kernel number per ear and yield of sample. Bokashi were significantly effect to plant height (at 2, 3, 5 and 7 weeks planted), leaf number (at 2 and 5 weeks planted), male flowering time, female flowering time and number of kernel per ear. The combination between varieties and phosphate fertilizer were not significantly different to whole parameters. The combination between varieties and bokashi  were significantly different to plant height (at 7 and 8 weeks planted). The combination between phosphate fertilizer and bokashi  were significantly effect to plant height at 2 weeks planted and kernel number per ear.   Key words : maize, varieties,  phosphate fertilizer, bokashi

Abstract

ABSTRACT One way to effort increase rice production is to expend the cultivation area of rice on saline soil, so it needs to test of some varieties in order the varieties can adaptation. This research aims to obtain varieties of rice (Oryza sativa L.) that can be adapted to saline soil. The research was conducted in the Desa Serdang, North Sumatera at ± 1 m altitude above sea level and 1.5 – 2 km from the beach. The research was carried out in May until October 2011. The design of the experiment was randomized block design with 18 varieties that carried out a preliminary test before, in order get 5 varieties that can adapted to saline soil. The results showed that 5 varieties can adapted to the saline soil is Banyuasin, Siakraya, Martapura, Dendang, and Margasari. Martapura was better than the other varieties on plant height, number of tillers, number of productive tillers, panicle length, wet weight of roots and grain productions parameter. Key words : rice, varieties, saline

Abstract

The use of Central Composite Rotatable Design (CCRD) to determine the response surfaceyield at maize not yet a lot of checked, for that an research have been conducted in UPT BBITanjung Selamat, Regency of Deli Serdang, Province of North Sumatra with the land height ± 25 mabove sea level, at May 2012 - August 2012.The design was used is randomized block design withtwo factors, the first factor is two varieties (Bisma and SHS-4) and the second factor is fertilizerNK (the dose of NK determined from CCRD). Parameters measured were: plant height, the numberof leaf, the number of leaf above cob, the time of tasselling, the time of silking, the time ofharvesting, the rate seed filling, cob lenght, cob diameter, the number of lines per cob, the numberof seeds per cob, weight of 100 seeds and production of dry seeds. The results showed that thevarieties significantly on plant height, the number of leafs, the time of harvesting and dry seedsproduction. Fertilizer sigificantly on production of dry seeds. Interaction of varieties and fertilizerNK significantly on production of dry seeds.

Abstract

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

Abstract

The adaptation of some shallot varieties has been conducted with the application of chicken manure andNPK fertilizer. The goal of this research is to know the adaptation of some shallot varieties in lowlandapplication of chicken manure and NPK fertilizer. The research was conducted at community land onPasar 1 Medan Selayang, Medan with altitude of 25 meters above sea level from May to July 2012. Usingrandomized block design. The first factor is three shallot varieties are Kuning, Medan, and Maja. Thesecond factor is four types of fertilizer; control, 240 g/plot chicken manure, 48 g/plot NPK, and chickenmanure plus NPK. The results showed that the varieties and fertilizer are significant in the fresh weightand number of cloves but not significant in plant height, number of tillers per hill, and dry weight. Whereas the interaction between varieties with fertilizers are not significant in all parameters. Heritability valuesranged from 0.03 - 0.87. All of the varieties tested have not been able to adapt well in the lowland interms of production so further studies using different varieties in the lowland is suggested.Key Words : shallot varieties, low land, chicken manure, NPK fertilizer.
