Sweet corn is one of the crops that has a fairly large role in provide the nutritional needs of the people. One of the effort that can be do to improve the growth and production of sweet corn is fertilization. The aim of this research are to determine the effect of interaction of cocoa peel’s compost and Urea, TSP and KCl fertilizer on growth and yield of sweet corn and get the best dose of treatment. This research was conducted experimentally by using Randomized Design Group (RDG) factorial with two factors namely cocoa peel’s compost treatment consist of 4 levels namely 0 ton/ha (K0); 2,5 tons/ha (K1); 5 tons/ha (K2); 7,5 tons/ha (K3) and Urea, TSP and KCl fertilizer treatment consist of 4 levels namely (50 kg Urea; 37,5 kg TSP; 25 kg KCl)/ha (P1); (100 kg Urea; 75 kg TSP; 50 kg KCl)/ha (P2); (150 kg Urea; 112,5 kg TSP; 75 kg KCl)/ha (P3); (200 kg Urea;150 kg TSP; 100 kg KCl)/ha (P4) with 3 replications. The parameters focus on plant height, the ratio of editorial root, cob length without cornhusk, the number of rows and cob weight without cornhusk/plot. The result of this research shows that the interaction of cocoa peel’s compost and Urea, TSP and KCl fertilizer there is no real effect to all the parameters. Giving cocoa peel’s compost 7.5 tons/ha and fertilizer (200 g Urea, 150 g TSP and 100 g KCl)/ha is the best dose of treatment. Key word: Sweet corn, cocoa peel’s compost, Urea, TSP, KCl fertilizer

This research aims to find out the effect of compaction of peatland on the physical propertiesat the two different locations. The research was conducted in October- December 2014 at society’s peatland in LubukOgong, Langgam, Pelalawan, Riau. The research used Factorial Split Plot Design (SPD) that consisting 2 factors and 3 replications. Factor I: compaction Level A1, A2, A3, and Factor II: the difference of Location B1 and B2 (Location 1 and Location 2). Parameters were observed those physical characteristics of soil included bulk density, particle density, total pore space, permeability, soil penetration, and water content. The data were analyzed by anova and the means were testedwithLSDsignificant level 5%. The result shows that the increasing of compaction of the peatland produces the increasing of bulk density and the decreasing of total pore space up to the soil deep 15-20 cm. Whereas the analysis result of the water content and particle density shows nonsignificant. The increasing of compaction is also reducing the permeability rate and increasing the value of soil penetration. Keywords: Compaction, Peatland, Physical Characteristics.

This research aims to find out the effectiveness of Neem and the application of Nitrogen to nitrogen leaching and sweet corn growth on peat soil. This research has been conducted in gauze house of Technical Implementation Unit (TIU) experimental station and analysis of leachate water has been conducted in Laboratory of Soil Science, Faculty of Agriculture, University of Riau, Pekanbaru. The research was held from October 2014 until January 2015. This research is factorial experiment and prepared in Completely Randomized Design (CRD) that consisted of 2 factors, which are nitrogen (N) application which is without nitrogen and with nitrogen 3,75g/column, and the second factor is Neem (M), which is without neem, 0,37g/column, 0,56g/column, 0,75g/column. The data that were obtained from research results were analyze statistically by analysis of variance (ANOVA). The result of ANOVA further were tested using Duncanâs multiple range test 5% significant level. The results of this research show that the application of neem until 0,75g/column dosage is not effective in decreasing nitrogen leaching on peat soil. The application of nitrogen on peat soil increases ammonium on leachate water on fourth week, but not on second and sixth week, while, on nitrat of leachate is significantly different compare to without application of nitrogen. The application of neem until 0,75g/column dosage and nitrogen 3,75g/column does not increase the growth of plant. Â Keywords : Neem, Nitrogen, Nitrogen leaching, Sweet corn, Peat soil

Pakchoy plants (Brassica chinensis L. ) is a plant that much in demand by the public because of high nutritional content. The limited agricultural land currently caused pakchoy cultivation declined, one of the ways that can be used to overcome this problem is to utilize the limited land by verticulture manner. Nutrients and water is a very important factor for plant growth of pakchoy, thus providing a variety of growing media and the provision of water can improve plant growth and production. Research has been conducted on the home screen Technical Services Unit Faculty of Agriculture, University of Riau from September to November 2014. The research conducted experimentally using Completely Randomized Design (CRD) consist 2 factors: embedding medium and the volume of water. The first factor is the growing medium consisting of three types of medium, M1=inceptisol soil, M2= 75% Inceptisol and 25% cocopeat, M3= 75% inceptisol and 25% ash sawdust and the second factor consists of 3 volumes of water that V1=100 ml/day, V2=200 ml/day, V3= 300 ml/day. Parameters measured were plant height, number of leaves, leaf area, fresh weight, weight suitable for consumption and root volume. The results showed that the volume of water with planting medium ash sawdust effect on growth and yield of pakchoy. Provision of water volume of 200 ml and the embedding medium ash sawdust with vertikultur system gives the best effect on plant height, number of leaves, leaf area, plant fresh weight, fresh weight of plants suitable for consumption, and root volume.
