Areca nut is widely used as industrial raw material, both for health and cosmetics and as a source of renewable energy. This study aimed to examine the combination of seed bombatriconditioning and LEISA fertilization treatments that were effective in increasing the growth of areca nut seedlings. The research was carried out in the Wua-Wua Kendari Village, from March to July 2021. The study used a split-plot design with a completely randomized design (CRD). The main plot is seed biomatriconditioning treatment which consists of 3 treatments. While the subplots were fertilized with the LEISA technique which consisted of 6 treatments so that 18 treatment combinations were obtained with 3 replications. Observations were made on plant height, number of leaves, stem diameter, number of roots, wet weight and dry weight of shoot. Observational data were analyzed using analysis of variance, followed by the DMRT α0.05 if there was a significant effect. The results showed that seed biomatriconditioning treatment with rhizobacteria integrated with the LEISA technique was able to increase the growth of areca nut seedlings. The integration between L1R biomatriconditioning and the application of organic plus fertilizer + 100% inorganic fertilizer showed a better growth performance of areca nut on plant height, number of leaves, stem diameter, number of roots, wet weight and dry weight of betel nut which were significantly different with control and application 100% inorganic fertilizer, but not significantly different from organic plus fertilizer, organic plus fertilizer + 50% inorganic fertilizer and organic plus fertilizer + 25% inorganic fertilizer. As a conclusion, pre-planting seed treatment with L1R biomatriconditioning is very important to increase areca nut seed germination. To increase the growth of areca nut seedlings, further fertilization needs to be done with organic plus fertilizer or a combination of organic plus fertilizer + 25% inorganic fertilizer.

Reproduction Method

Arachis pintoy can be reproduced in generative but also vegetative way, for example through cuttage. Problems arising from this reproduction method is the difficulty to form roots. The success rate of this method depends significantly on the size of the formed callus. To analyze the content of nutrients contained in the cuttage stem, we have to cut off the stem. And then it’s necessary to find out additional factors that can influence the forming of the callus with a large percentage of rooting. One alternative solution is the provision of coconut water which believed to contain a variety of nutrients and growth substances. Therefore, we conducted a study to find out the interaction of these two factors on the growth of Arachis pintoy The purpose and goal of this research is to study and identify the growth Arachis pintoy which treated with coconut water its influences on the stem length. This research has been performed in Agrostology Lab of Animal Husbandrys Faculty of Sam Ratulangi University, during a period of 60 days. The research materials consists of Arachis pintoy, Coconut Water and soil. While the research method use 2 experimental factors: Factor A is the Coconut water, Factor B is the after-cuttage-stem length of Arachis pintoy, which arranged through completely randomized design (CRD). Each factor consists of 3 treatments, which repeated 3 times. These factors are as follows: A = volume of Coconut water, A1 = 100 ml of coconut water, A2 = 200 ml of coconut water, and A3 = 300 ml of coconut water. Factor B = stem length of Arachis pintoy, B1 = 10 cm, B2 = 15 cm, and B3 = 20 cm. And the variables which measured in this study were plant height, dry weight of roots and the roots volume. The results showed that administration of coconut water and the length of the cuttings as well as the interaction of two factors give significant effect (P < 0.05) to the growth of the number of leaves and root dry weight of the Arachis pintoy . Furthermore, coconut water does not give effect to the root volume and a combination of two factors do not impact on the growth of plant height. From the data analysis and discussion for all variables in this study , we can conclude that the best combination of growth in the number of leaves , dry weight of roots and root volume is the provision of 300 ml of coconut water and 10 cm stem length. Keywords: Arachis pintoy, coconut water and stem length

Background: The purpose of this research was to evaluate the growth and bulb yield of shallot (Allium cepa L.) varieties grown by TSS with different population.Methods: This study was carried out in the low dry land at Laleten Village, Malaka District, NTT Province, Indonesia, from March to August 2018. We investigated different plant populations per planting hole using a split-plot design with two factors and four replications. The main plot was the varieties (Trisula and Bima Brebes) and the subplots were the seedling population (100, 200 and 300 plants/m2).Result: There was no interaction between varieties and population for any of the measured parameters. The population only affected the plant height at the beginning of plant growth. A high plant population (300 plants/m2) gave the highest production of single bulbs but was negatively correlated with the bulb weight. Trisula variety produced significantly more single bulbs than the Bima Brebes one. The establishment of the TSS-adapted varieties could be recommended in this area.
