Shortening Dormancy Period of Oil Palm Seeds (Elaeis guineensis) using Sulfuric Acid (H2SO4) and Gibberellic Acid (GA3) Solutions

Soaking oil palm seeds in a solution of sulfuric acid and gibberellic acid is one way to shorten the dormancy period of oil palm seeds. This study aimed to find out the optimum soaking time of oil palm seeds in sulfuric acid solution to accelerate germination, the optimum concentration of gibberellic acid for oil palm seed germination, the interaction between using sulfuric acid and gibberellic acid in accelerating the germination of oil palm seeds and the best treatment combination in all the tried treatments. The experimental design used was a completely randomized design (CRD), with a complete factorial combination with a total of 16 treatments. Each treatment was repeated 4 times, so there were 64 experimental units and each unit was planted with 5 seeds. The results of statistical analysis showed that soaking oil palm seeds in a solution of sulfuric acid and gibberellic acid had an effect on the germination of these seeds. The duration of soaking oil palm seeds for 48 hours in sulfuric acid solution constituted the optimum time for increasing the speed of germination and giving gibberellic acid at a concentration of 300 ppm still accelerated the germination of oil palm seeds and there was no interaction between the length of soaking the seeds in sulfuric acid solution and the concentration of gibberellic acid. Soaking the seeds in a solution of sulfuric acid for 48 hours and gibberellate 300 ppm was the best combination treatment to accelerate the germination of oil palm seeds.

Low productivity of oil palm in Ultisol need to resolve by utilizing appropriate input and efficient soil management. Utilization of organic waste materials such as oil palm empty bunches (OPEB) is one of way for that. This research was conducted in Kuantan Singingi, Riau from September 2017 to February 2018. The aim of this research is to having dose of OPEB compost and NPKMg fertilizer that can optimize the value of soil chemical characters and nutrient content in leaves. The study determined the effect of composite oil palm empty bunches with cow manure (2:1(w/w)) and NPKMg (13:6:27:4) fertilizer. The study used a completely randomized design consisting of 6 levels :{(2,25 kg NPKMg), (10 kg OPEB compost + 1,75 kg NPKMg), (20 kg OPEBcompost + 1,5 kg NPKMg), (30 kg OPEBcompost+ 1,25 kg NPKMg), (40 kg OPEBcompost + 1,00 kg NPKMg), (50 kg OPEB compost) per tree}, each treatment was repeated 3 times. Parameters measured include soil chemical characters and nutrient content in leaves. The results of study showed, aplication 50 kg per tree TKKS compost was able to increase soil pH. Aplications (2.25 kg NPKMg, 50 kg TKKS compost, 20 kg compost TKKS + 1.50 kg NPKMg and 30 kg compost TKKS + 1.25 kg NPKMg) per tree can increase base saturation. Each treatment application for fertilization has been tested, given the same effect in all soil chemical characters tested beside pH and KB, and same effect in all leaf nutrient contents tested beside Zn.Key words : Palm Oil, Compost, OilPalmEmptyBunches, NPKMg

Response of Oil Palm Seedling (Elaeis guineensis) In Pre Nursery On Giving Doses of Nasa Liquid Organic Fertilizers and Intervals. The purpose of this research is to know the doses and interval of Nasa organic liquid fertilizer (OLF) and the combination of dosage and OLF Nasa interval to the best palm seeds in pre nursery. The research was conducted in UPTD Seed Plantation Plantation Supervision of East Kalimantan Province in 2015. The study used Factorial completely randomized design (CRD) 5 x 4 with nine replications. The first factor was the treatment of OLF Nasa doses in a concentration of 3 cc OLF Nasa per liter of water (D) consisting of 5 levels, namely: d0 = 0 ml OLF Nasa, d1 = 300 ml OLF Nasa, d2 = 400 ml OLF Nasa, d3 = 500 ml OLF Nasa and d4 = 600 ml OLF Nasa. The second factor is the treatment of OLF Nasa (I) Interval Interval consisting of 4 levels, namely: i1 = 1 week, i2 = 2 weeks, i3 = 3 weeks and i4 = 4 weeks. Thus there were 16 treatments and each treatment was repeated 9 times so that the total was 180 seeds. Data were analyzed statistically and tested further with the smallest real difference test (BNT) at 5% level.The results showed that the dosage of 500 ml OLF in the concentration of 3 cc OLF Nasa liter-1 of water gave the highest plant height that is an average 28.73 cm. While the OLF Nasa interval once a week gives the highest plant height is an average of 29.33 cm.

And Chemical Properties

The first problem faced in cultivating oil palm is the procurement of seeds. Ultisol soil when used for breeding media has several problems such as having a wet saturation of less than 35% at a depth of 125 cm below the upper limit of the argillic horizon. Ultisol has an acidity level of less than 5.5, low to moderate organic matter and low nutrition. The addition of organic material such as the LCC Mucuna bracteata compost is highly recommended because it will improve the physical, biological, and chemical properties of the soil, so that it increases the availability of nutrients in the soil to be optimal. This study aims to determine the effect of LCC mucuna bracteata compost on ultisol soil medium and determine the dosage/dose of LCC Mucuna Bracteata compost which provides the best growth of oil palm seedlings (Elaeis guineensis Jacq). This research was carried out experimentally with a Completely Randomized Design (CRD), consisting of 5 treatments and 4 replications. The results of this study indicate that distributing doses of 400 g/8 kg of soil improved the physical and chemical properties of the soil and the vegetative growth of oil palm seeds.

The aims of this research to determined the effect wet heating and immersion in gibberellins on breaking dormancy of oil palm seed. The treatment was arranged in factorially with two factors in the Completely Randomized Design. The first factors was wet heating which consists of five levels, (1) 20 days of heating; (2) 25 days of heating (3) 30days of heating (4) 35 days of heating (5) 40 days of heating. The second factor was the concentrations of gibberellin in four levels, (1) 0 ppm; (2) 100 ppm; (3) 200 ppm and (4) 300 ppm. Based on the results could be concluded that (1) wet heating could increased the percentage of germination, maximum growth potential, speed of germination, and time of emergence of sprouts, (2) 30 days wet heating treatment + immersion in 200 ppm giberelin was the best treatment in percentage of germination (64 % ± 1.3), maximum growth potential(70.7%±1.4), and speed of germination (29% ± 1.0 per etmal).
