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 Effect of Dosage of P and K Fertilizer on Growth and Production of Red Onion (Allium ascalonicum L.) Bima Varieties. The purpose of this research is to know the influence of P and K fertilizer application and the interaction of the two treatments on the growth and production of shallot plant. The study was conducted for 3 months, ie from July to October 2016. The research site on land owned by UPTB Samarinda Agriculture Training Center East Kalimantan Province. This study used Randomized Block Design (RBD)  with a 3 x 4 factorial experiment consisting of 4 replications. The first factor is fertilizer fertilizer P which consists of 3 levels: namely p0 (without fertilization), p1 (fertilization 1 gr / plant), p2 (Fertilization 1.5 g / plant). The second factor is the dosage of K fertilizer consisting of 4 levels ie k0 (without fertilization) k1 (0.5 g / plant) k2 (1 g / plant) and k3 (1.5 g / plant). The result of this research showed that the treatment of P (P) fertilizer had significant effect on plant height 2 and 3 MST, wet bulb weight and dry bulb weight and no significant effect on plant height of 4 MST, number of leaves, and number of tillers. While the application of K (K) fertilizer had significant effect on plant height and leaf number at age 2 MST and no significant effect on height and number of leaf aged 3 and 4 MST, number of tiller, wet bulb weight and dry bulb weight. There was no interaction between P and K fertilizer application.

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.

Abstract

The Influence of NPK Phoska Fertilizer and Liquid Organic Fertilizer on Banana Plant Growth and Production (Musa sp). The purpose of this study was to determine the effect of NPK Phoska fertilizer and liquid organic fertilizer on the growth and production of banana rutai plant. The study was conducted for 7 (seven) months, from February to September 2015, starting from land preparation to data collection. This research was conducted on campus of Widya Gama Mahakam Samarinda. The research design used was factorial randomized block design 3 x 3 with 3 times replication. The first factor was Phoska NPK fertilizer (P) consisting of 3 levels: P0 (Without Treatment), P1 (1080 g / plant) and P2 (1580 g / plant). The second factor is the application of liquid organic fertilizer (B) 3 levels, namely: B0 (Without treatment), B1 (5000 ml) and B2 (10000 ml). The result of the research showed that the best treatment of NPK Phoska P2 (1580 g / plant) was the average of plant height 90 days after the highest treatment was 122.33 cm, the largest mean stem diameter was 11,08 cm and average the highest number of comb per bunches is 7.22 comb, the fastest harvest age is 248 days after planting. The best treatment of liquid organic fertilizer to the average number of combs per cluster was achieved at the treatment of B1 (5000 ml) ie 5.33 comb, the fastest harvest age 248 days after planting. The interaction between NPK Phoska fertilizer application and liquid organic fertilizer did not significantly affect all observation parameters.

Abstract

The aim of this research is to know the effect of shade and dosage of palm oil ash as well as their interaction to the root of oil palm plantation in pre nursery. This research was carried out in Nursery Faculty of Agriculture, Mulawarman University, Samarinda from February to May 2011. This research is an experiment arranged in Completely Random Design (RAL) with split plot analysis (4 x 4) with 5 replications. The main plot is the level of shade reduction (N) at the age of 10 weeks which consists of four levels, namely: no = Shade minus 100%, n1 = Shade minus 75%, n2 = Shade minus 50%, n3 = Shade minus 25%. As a plot child is a dose of ash (D) consisting of four levels: d1 = 11.5 g of ash / polybag equivalent to 23 tons / ha, d2 = 23 g of ash / polybag equivalent to 45 tons / ha, d3 = 34.5 g of ash / polybag equivalent to 68 tons / ha, d4 = 45 g of ash / polybag equivalent of 91 tons / ha. Data were analyzed statistically and tested further with the smallest real difference test (BNT) at 5% level. The results showed that the treatment of ash dose 23 g ash / polybag or equal to 45 ton / ha (d2) gave wet weight, dry weight, wet weight of leaf, average dry weight of leaves 5,51 g, 2,32 g , and 5.08 g. The shading treatment gives a mean wet weight of roots 1.90 g.
