Abstract

One of the obstacles in increasing and stabilizing crop production is the onslaught of soil pathogens that causes damage to plants and decreases the quantity and quality of production. This study aims to identify and determine the population of rhizosphere microorganisms in rambutan plants. The research was conducted at Plant Pest and Disease Laboratory of Agricultural Faculty of Mulawarman University of Samarinda from July to August 2016. This research uses exploration method with observation technique which is done by growing microorganism in media so that for 5 days then calculate growth rate of each microorganism. The data obtained were analyzed using quantitative descriptive analysis. Based on the result of the research, it can be concluded that the results of isolation of micorganism from rhizosphere rambutan plant obtained 3 isolates include: 1 isolate bacteria from Azotobacteraceae Family and 2 isolates of fungi from genus Aspergilus and Phytium genus. Of the 3 types of isolates, 2 types of microorganisms are included into microorganisms that are beneficial to soil ecosystems that include the Azotobacteraceae Family that play a role in the fixation (fixation) N2 (biofertilizer) and Aspergillus Genus that act as a potential pathogen growth inhibitor (bio control) diseases in plants while the Phytium Genus is a pathogenic fungus (the cause of disease) that can affect the low production of plants.

Abstract

The Influence of Compost Fertilizer And Grenn Tonic Fertilizer On The Growth And Results Of Rawit Chili Plants (Capsicum frustescens L) Bhaskara Varieties. The purpose of this research is to know the response of the use of compost fertilizer, Green Tonik liquid fertilizer and the interaction between compost fertilizer and Green Tonik liquid fertilizer on the growth and yield of pepper plant. The study was carried out for approximately 4 months, starting from July to October 2015, the research site at Jl. Thoyib Hadiwijaya Sempaja Timur, North Samarinda, East Kalimantan Province. The study was carried out for approximately 4 months, starting from July to October 2015, the research site at Jl. Thoyib Hadiwijaya Sempaja Timur, North Samarinda, East Kalimantan Province. This research method used Randomized Block Design with 4x4 factorial analysis consisting of 3 replications. The first factor is compost (k) consisting of 4 levels: k0: (control), k1: 50 g / polybag, k2: 100 g / polybag and k3: 150 g / polybag and second factor is Grenn Tonic (g) which consists of 4 levels: g0: (control), g1: 1.5ml / liter of water, g2: 3 ml / liter of water and g3: 4.5 ml / liter of water. The results of the compost fertilizer (k) showed that the effect was very significant on the average height and diameter of the plants at the age of 27 days HST, 40 HST and 53 HST as well as the average of crop yields, the highest crop yield on the treatment k2. The Green Tonic fertilizer treatment (g) showed that significantly affected the mean height and diameter of the plants at 27 days of HST, 40 HST and 53 HST as well as the average crop yield, the highest crop yield on treatment g2. In the second interaction treatment of compost (k) and Green Tonic (g) fertilizer had no significant effect on average of plant height increase, early age of flower, early age of harvest and fruit weight.
