Abstract

The aim of this research is to determine the effect of application of Trichocompost and to get the best dosage on the growth of young oil palm plants in main nursery stage. The research was conducted at the experimental unit of Agriculture Faculty, University of Riau from May to August 2014. This researchwas arranged experimentally using Completely Randomized Design(CRD), consistins of5 treatment sandeach treatment repeated 3times. The treatments are dosage of Trichocompost: without application Trichocompost (T0), application Trichocompost 25 g/polybag (T1), 50 g/polybag (T2), 75 g/polybag (T3), and 100 g/polybag (T4).

Abstract

Palm oil (Elaeis guineensis Jacq) is a crop plantation were a high economic value because it is a vegetable oil plant. In Indonesia, oil palm is important to increasing the country's income and able to improve people's fare well, especially in Riau Province. The study aimed to examine the effect of formulations liquid organic fertilizer contain active Bacillus sp. and get the best formulations on the growth of oil palm seedlings (Elaeis guineensis Jacq). The research was conducted in Quarantine Laboratory, Pekanbaru and in the technical implementation unit of agriculture faculty of Riau University, in April until to October 2013. The methods of research is experimentally with using randomized block design (RBD) with 5 treatments and 4 replications. The data were analyzed statistically with using analysis of variance and followed by Duncan’s New Multiple Range Test at level α = 5%. The parameters measured were increase of seedling height, increase of the number of midrib, increase of circle stem, seedling root volume, root crown ratio and dry weight of plants. The results of the research showing that all treatment of formulations Bacillus sp. were tested has non significant effect on all parameters of observation. Formulations of Bacillus sp. with coconut water is the best formulation in increasing of palm oil seedling height and the tendency towards in increase of number of the midrib and plant dry weight.

Abstract

ABSTRACT The number of plants per hectare is an important factor to get high yields. The number of plants widely unity depends on variety, age, soil fertility and water conditions. Through proper spacing between plant pineapple level of competition can be reduced as low as possible. The use of plant growth regulators (PGR) is required to support the growth and development of the pineapple plant. The aim of this study to determine the effect of spacing and administration of the growth hormone auxin on pineapple among immature oil palm plantations on peat land. This study was conducted with randomized block design experiment with 2 factors and 3 replications. The first factor is the spacing treatment, and for the second factor is the use of the hormone auxin. Then proceed to test the value of the middle HDS (Honestly Significant Difference) the 5% level. The parameters measured were plant height increase, in the number of leaves, the length of the leaves, leaf width accretion, plant fresh weight, dry weight of plants. The results showed the interaction of treatment and the spacing of the hormone auxin significant effect on the number of leaves but not on other parameters. Spacing factors did not significantly affect on all parameters. However, the hormone auxin treatment only significantly affects the leaf number, fresh and dry weight.. Keywords: Ananas comosus (L) Merr, Distance Planting, hormone auxin

Abstract

Organic fertilizers can be used for a cacao nursery is vermicompost, whereas inorganic fertilizer that can be used are urea. The purpose of this study was to determine the effect of vermicompost fertilizer and urea as well as getting the best combination treatment for the growth of cocoa seedlings. This research used experimental method using a completely randomized design (CRD) with 2 factors and 3 replications. The first factor is the dose of vermicompost fertilizer (K) which consists of 4 levels and the second factor is the dose of urea (U), which consists of 4 levels. The parameters measured were seedlings height (cm), number of leaves (leaf), girth (cm), leaf area (cm2), ratio feature roots and dry weight (g). The data analysis results were significant statistical test followed by Duncan's test New Multiple Range Test (DNMRT) at the 5% level. The conclusion of this analysis is that combination treatment of vermicompost fertilizer at a dose 75 g/polybag and urea 0.750 g/polybag affect leaf area and ratio feature roots. Vermicompost fertilizer factor at a dose of 75 g/polybag on cocoa seedlings affect seedlings height, girth, leaf area, ratio feature roots and dry weight, but had no effect on the number of leaves. Urea fertilizer factor at a dose of 0.750 g/polybag on cocoa seedlings affect seedlings height, leaf area and ratio feature roots, but did not affect the number of leaves, girth and dry weight. Keywords: cocoa, vermicompost, urea, combination treatment

This research was conducted in the experiment stationthe Faculty of Agriculture, University of Riau, Pekanbaru startied from November 2014 through April 2015. The research was conducted experimentally usingcompletely randomized design (CRD). The data were statistically analyzed using analysis of variance, followed by Duncan's New Multiple Range Test (DNMRT) at 5%. Parameters observed were plant height (cm), stem diameter (mm), number of leaves (pieces), leaf area (cm²), seeds dry weight (g) and the ratio of crown roots (g). The results showed that application of Azolla microphylla compost on cocoa seedlings significantly affected stem diameter and has no significant effect against high seedling, number of leaves, leaf area,seed dry weight and root crown ratio, however there was an increasing trend in growth of high seedling, number of leaves, leaf area, the weight of dry seed and root crown ratio without the application of Azolla. microphylla compost.
