Abstract

The research about Test Of Some Azolla pinnata Liquid Fertilizer Concentration On The Growth Of Oil Palm Seeds (Elaeis guineensis Jacq.) In Pre Nursery has been done in the experimental garden of Agriculture’s Faculty, University of Riau. This study aimed to determine the effect of Azolla pinnata liquid fertilizer and get the best concentration for the growth of oil palm seeds in the pre nursery. This Research was caried out experiments using a Completely Randomized Design (CRD), which consists of 5 treatments and 4 replications, the treatments were A1: Azolla liquid fertilizer concentration 50 g/l, A2: Azolla liquid fertilizer concentration 75 g/l, A3: Azolla liquid fertilizer concentration 100 g/l, A4: Azolla liquid fertilizer concentration 125 g/l, A5: Azolla liquid fertilizer concentration of 150 g/l. The results show the Azolla liquid  fertilizer significantly effected on plant height, number of leave, stem diameter  and dry weight of plant, but not significantly effected root crown ratio. Azolla liquid fertilizer application at a concentration of 100 g/l and 125 g/l gives the best result and increasing the growth of oil palm seeds in pre nursery.   Keywords: Azolla liquid fertilizer, oil palm, pre nursery

Abstract

This study aim to determine the effect of compost on the growth of           Azolla microphylla PB 260 clone rubber seedlings mini stump. This research has been conducted at Agriculture Faculty, University of Riau starting from April to July 2013. The research was carried out experimentally using completely randomized design non factorial consisting of 4 treat ments  and 3 replications, obtained 12 experimental units and each unit consists of 3 seeds so that total earned is 36 rubber seedlings and as sample 2 seedlings per unit experiment. Compost treatment given to the provision of  treatment levels; 0, 15, 30 and 45 g/polybag (0, 10, 20 and 30 ton/ha) mixed by weighing soil 3 kg. The data were statistically analyzed using analysis of variance, followed by Duncan's test New Multiple Range Test (DNMRT) at the level of 5%. Parameters observed are lenght of grafting (cm), stem graft girth (cm), number of leaves (sheet), leaf area (cm²) and shoot root ratio (g). Giving Azolla microphylla compost on growing mini stump  rubber seedling significantly effect on extending the graft and number of leaves. Meanwhile, for stem graft girth, leaf area and shoot root ratio reveal not significant. Compost dosing 30 g/polybag shows the best results for the growth of rubber seedlings mini stump compared them 0, 15 and 45 g/polybag.

Abstract

This study aims to determine the implementation of non-governmental palm oil cultivation techniques (Elaeis guineensis Jacq) in tidal area on Bangko Pusako District Rokan Hilir Regency. The research was conducted on tidal land at the village of Bangko Kanan and Bangko Kiri in Bangko Pusako District Rokan Hilir  Regency, from April to July 2013. This study was conducted using survey and processed data presented in descriptive form. The number of respondents in this study were 40 respondents, based on  5% level of representation. 17 respondents drawn from the Bangko Kanan and 23 respondents drawn from the Bangko Kiri. The parameters studied were the origin of the seeds, plant spacing, size of planting holes, transplanting seedlings to the field, eradication of weeds, fertilizing, castration, plant population/ha, water level measurements and measurements of distance of land from the river. The results show that the average production of farmers palm oil are still very low at less than 50% when compared to the average production of palm oil of PTPN V on mineral lands in general. The low production of palm oil cultivation techniques of farmers due to conducted as seed origin, plant spacing, pattern spacing, the size of the planting hole, transplanting seedlings into the ground, fertilizing, castration and plant population/ha are still quite low level of the appropriate palm oil cultivation techniques application in the field.

Abstract

Cocoa (Theobroma cacao L.) is a plantation crop that has a high economic value, but low productivity and quality of cocoa in Indonesia due to substantial losses. One of many efforts we can do to improve the quality and quantity of cocoa production is through improving the quality of seeds. Fertilizing is one of important factor on the growth of cocoa seedling. Application of organic material as fertilizer can give a good effect for plants. One of many organic material that can be used is a mixture of vermicompost. This study aim is to determine the effectof vermicompost on the growth of cocoa seedlings and get the best doses for the growth of cocoa seedlings. This research was conducted in the experimental field of Agriculture Faculty, University of Riaufrom September to December 2014. This research was carried out using completely randomized design (CRD), which consisted of 4 treatments with 3 replications. The treatments consisted of :(K1) without vermicompost/plant, (K2) 15 gvermicompost/plant, (K3) 25 gvermicompost/plant, (K4) 35 gvermicompost/plant. The results showed that the giving of vermicompost on cocoa seedlings effected on seedling height, number of leaves, girth and leaf area. Giving vermicompost 25 g/plant the best results on the growth of cocoa seedlings.   Keyword: vermicompost, organic material, cocoa seedling

Plant oil palm (Elaeis guineensis Jacq.) is a plantation crop which plays an important role for Indonesia as a mainstay commodity. Palm oil seedling is the planting of seedlings in a planting medium, so that the seeds are ready to be planted permanently in plantations. The research aim is to determine the effect of the use some liquid fertilizer animal urine on seedlings of oil palm (Elaeis guineensis Jacq.) and get the animal urine liquid fertilizer suitable for oil palm seedlings. Research was conducted at the Faculty of Agriculture, University of Riau, from January to April 2015. The study conducted using completely randomized design (CRD), which is consists of 5 treatments, each treatment was repeated 4 times to obtain 20 units of trial, as for the treatment given is a liquid fertilizer that consists of animal urine: sheep urine, goat urine, urine buffalo and cow urine. Data were analyzed using ANOVA and continued with further test Honestly Significant Difference (HSD) at 5 %. Research that has been carried out, showing that administration of liquid fertilizer urine of different animals on oil palm seedlings showed the real effect of the parameters as height of seedlings, the increase in diameter hump, increase the number of stem of leaves and root volume, while observations ratio crown roots and dry weight of seedlings show the effect is not real.

Abstract

The process of developing oil palm cultivation is closely associated with the availaibility of quality seed. Quality seed is very determining the growth and production of such commodities. Supply of cocoa peel’s compost into the soil may increase the availability of nutrient elements both macro and micro. The research is aimed to know the influence of of cocoa peel’s compost on the growth of the oil palm seeds in the main nursery. The research was carried out experimentally by using Completely Randomized Design (CRD) with consists of four treatments and three replication. The results of research that application of cocoa peel’s compost to the oil palm seed is significantly to seed height increment, but not significantly to the number of leaves, diameter of excrescence, the ratio of the editorial root and dry weight. The application of cocoa peel’s compost with increasingly high doses tend to increase diameter of excrescence and dry weight of oil palm seed, while on parameters the number of leaves and the ratio of the editorial root not tend to increase of growing oil palm seed. The application 150 g compost/polybag or same with 37,5 ton/ha, shows the best growth of oil palm seed. Key Word : Cocoa Peel’s Compost, Oil Palm Seed
