Abstract

This research was comiucted in Green House and Soil Laboratory, Andalas Univeraity, Padang. Theresearch aimed to study the efTect oflimiag in acid soil (Ultisol) to nitrogen content of green mannrecrops.The experiment used Completely Randomaed Design of factorial 7x 2. Tbe first factor was f^enmanure crops, consisted of seven levels (CalioHibn tetragma, Flemingia coHgefta, GKriddia stpmm,Leucaena leucocepkala, Leucaena gktttca, Seshania rostrata, SesbaHta seshoK) and second factor was limeaddition, consisted of two levels ( without liming and IxAi-dd). The result of research for four times cattingsindicated that: (1) The highest total N without liming was Fkmuigiaa>i^esta (1225,96 mg/pot), and Leacaenaleueocepkala (2729,53 mg/pot) in acid soil with liming It Al-dd; (2) Tbe highest increasing percenUges oftotal N as responses to liming were Cailandra taragona (67,48%), LeHcaena leucocqtkala (61,29%),Gliricidm sepium (57,75%), Sesbaida sesbim (44,60%), [Micaena glauca (43,44%), and Flemingia etmgesta(18,83%); (3) Flemingia congesta was very tolerant to acid so9 and (Miandratetrvgomt was very responsiveto liming.

Abstract

Maize production technologies that are available on the fertile land has been able to increase prodnctivityfrom 5.0 to 10.0 tons of dry beans per hectare, but the technology on marginal lands such as peatbinds are notyet avaihibte so its productivity is veiy low. Dregs is alkaline and conuins essential macro and mkro nutrientsso it has potential to be applied as fertilizer and ameliorant in peat The research aimed to study the growth andproduction of sweet com, with application of iregs as ameiiorant and phosphorus source. Peat soil wasobtained from experiment plot, faculty- of ^ricuHure in Rambo Panjang village, Kampar and firqpi was obtainedfrom PT RAPP Kcrinci, Riau. Experiments used completely randomized design of factorial 4x4 which werearacliorant dregs (0, S, 10 and 15 tons/ha) and source of phosphate (SP-M, FA Huinan China, ChristmasIsland and Petrokimia Gresik) and each treatment was repeated 3 times. Dregs characterization resultsshowed that solid waste is not identified as waste according to Rcgulatkin No. B3. No. 18 Jo. 8S Year in 1999.Dregs Applications of 5 tons / ha increased dry weight of straw and crop production of 93-97% and 106-l<3*^ respectively on each source of phosphate compared with no application of dregs. Tbe highest dryweight of straw and production of about 150-260% were obtained at dregs application of 10 tons / ha whiledregs application of 10 tons / ha resulted in the highest production of about 150-260%.

Tbe research was conducted at Aur Sati VUiage, Tunbang sub district, Kanspar District, Trom May toNovember 20O7, using survey method. Tbe aim of this research were to get information about condition offarming system and to identify marketing potential of low land vegetables with high productkin and goodmarketing potential. Result of research showed thattowland type vegetable with the highest production blong bean and encumber, but tiie one with best marketing potential b spinach. Spinach had highest sellingpercentage eventhough the one with highest profit percentage was long bean.

Abstract

The main factor causingtownational rke production is the km productivity ofricecrops in Indonesiathat is less than 4.66 ton/ha in mineral soil. Efforts to expand rice cultivation is very limited, because thefertile hnd has no longer available while marginal land still has obstacles (o develop cultivation of paddies.Some of tiie proUenis encountered in wedand development in Indonesiatekm pU so3 which shouM be improvedand limited soil nutrient availability, increase in the solubiiity of Fe and Fe toxklty problem, lack of potassiumdement because ail crops were tramiported oat; goieral fertilizerrecommendationis applied for each tocatktn/diirereot land; lack of research on h>cat)on-specifk fertilizer recsommendatiott; much water is needed (o moistsoil; and land productK'ity is still low. Optimal management of wetland win affect some aspects such as: soilnutrient status of fidds needs to be tested as a baus for determining fertilizer recommendation: microbialfertilizer technology to improve the efTiciency of fertilization, irrigation and leaching processes on wetlandmanagement can change tbe chemical properties of soil, crop ntaiugement development in traditional Indonesianrice cultivation should be done with SRI, because it can increase the productivity ofriceand of sustainableagriculture.

Abstract

Kailan (Bnusiea aiboglabra L) is horticultural crop as food substance required by human iieingwith high economic value. This research was carried out using Complete Randomized Design with sixtreatments and three replications. Treatments were: without application of KJVO^ (control), application of 0.5g/polybag KNO, and 1 g/potybag KNO, to die soO, 2 g«1,4 g/l, and « g1 KNO^ sohition applied to the leaves. Ilie/result of the research showed tliat the applicatktn of KNO, significantly affected the crop age, fresh weq(ht ofthe crop and consummable weight. The best treatment was application of KNO, solution to the leaves withconcentration of 4 g/L.

Abstract

Tliis research was conducted to determine tbe residue efTect of sawdust ash and worm compost inpeat medium after tomato pbinting on the growth and yield of shallot This research was carried out in thegreen bouse of Faculty ofAgriculture, Riau University. The design was Complete Randomized Design (CRD),with four factors and three replications. The first factor was residue of sawdust ash after tomato plantingwhich consisted of four levels (0,10,20 and 30 ton/ha) and tbe second factor was resklue of worm compostafter tomato planting with four levels (0,5,10 and 15 lon^a). The result showed that the residue of sawdustash and worm compost had positivecRect on the growth and yield ofshaHot The highest result was found forresklue of 30 ton/ha sawdust ash and tO ton/ha worm compost after tomato planting.

Abstract

The research objective was to determine the effect of skin hieation on the stem and material sizeduring distWation process toward yieM and quality of cinnamon oil {dimaimmutm bumuum Blume). Researchmethod used was fnctorial in Randomized Block Design with two treatments. The treatmoits were the location/height of skin (30cm, 60 cm and 90 cm from the base ofthe stem) and the size of the material (smaB, mediumand large). Replications were conducted three times and then continued with DNMRT test if there is anysignificant d ifference among the treatments. The parameters used were oil yieM, spedfic gravity, refractiveindex, optical rotation, solubility in akohol and total sinnamahiehide The result showed that the highest oilyield, specific gravity and refractive index contained in the combined treatment of higher locatiofl on stem (90cm) and smaller material size. Foroptiad rotation the highest value contained in combined treatment of tergermaterial size and higher skintocationon the stem (90 cm). The h h s value for the solubility in alcohol and% ettotal sinnamaklehHie contained in combined treatment oflarger size material and lower locatkin on the stem(30 cm). Cinnamon o8 produced still fulfils the quality standard of Indonesfain cinnamon oil (SN1).

Abstract

This research aimed to know the dose of pota«ium Tertilizer, phnt spacing and sawdust ash toincrease production of ginger and com planted at multiple cropping system. TMs research was conducted byCompletely Randomized Btocii Design (RAK) factorial consisted of 2 facton and 3 replications. The researchstarted on April and fmisbed on Augnst 2<m. The first factor was potaasinm fcrtlizcr with dose ofO kg KCVha, iOO kg KCI/ha, 200 kg KCI/ba, and 300 kg KCI/ha. The second factor was different plant spacmg ofginger crop which were 25 i3S cm, 30140 cm, and 35 x 45 cm. Every treatment and replication was 2 x 2 m.Parameters observed were height of ginger crop and corn crop, relative growth rate of ginger and corn,number of ginger crop, wet weight of ^nger crop, dry weight of ginger crop, the timeflowersappear of corn,dry grain weight of com crop, and weight of 100 com grains. The result of linear analysb of variant wascontinued by Duncan New Multi|rie Range Test (DNMRT) at 5 level Researchrasnhindicated that application%of potassium fertilizer with dose of 100 kg/ha and 25 x 3S cm of ginger crop spacing represented the besttreatmen t to increase production of ginger and application of potassium fertSizer with dose of300 kg/ha and30 X 40 cm, 35 x 45 cm represented (he best treatments to increase production of corn.
