This study aimed to determine the growth and production of katokkon chili plants (Capsicum chinense Jacq.) in the application of gibberellins and liquid organic fertilizer. This research was conducted at the Experimental Farm of the Faculty of Agriculture, Universitas Hasanuddin, Makassar from May to October 2017. The research was conducted in the form of a two-factors factorial experiment. The first factor was gibberellins consisted of four levels namely 0 ppm, 25 ppm, 50 ppm and 75 ppm, and the second factor was liquid organic fertilizer consisted of three levels of 25 ml L−1, 50 ml L−1 and 75 ml L−1 with three replications. Results of the study show that application of gibberellins on the local chili plant of katokkon interacted with liquid organic fertilizer improved the vegetative growth of the plant. Gibberellin also significantly affected the production parameters of the local chili plant. The fruit weight per plant and per hectare decreased with the increased of gibberellin dosages. No significant effect of the use of liquid organic fertilizer found, however, the treatment of 75 ml L−1 showed better results in several research parameters.

One of the obstacles faced in the expansion of the dragon fruit planting area is limited cutting materials to produce high quality seedlings. This study aimed to study the growth of dragon fruit (Hylocereus costaricensis L.) seedlings from two sources of cuttings at various concentrations of shallots. The research was conducted at the Teaching Farm of the Faculty of Agriculture, Universitas Hasanuddin from November 2018 to February 2019. The trial was set based on Split Plot Design with source of cutting materials as the main plots, consisted of two types of sources ie. apical primary branch and basal primary branch, while concentration of shallots solution as sub plot, consisted of five levels, namely 0, 200, 400, and 600 g.L−1 water, and Rooton-F 10 gL−1 water. The results show that the growth of the dragon fruit seedlings from two different sources of cuttings at various concentrations of shallots did not show significant differences. Sources of cuttings from the basal of the primary branch gave the best results on the number of shoots (2.40 shoots). Application of various concentration of shallot solution resulted in the highest percentage of life cuttings (100%) compared to control (75%). The concentration of shallot solution of 600 g.L−1 water showed the highest results in shoot length (28.33 cm), root length (31.09 cm) and root volume (66.67 mL). The use of Rooton-F as a positive control gave the highest results in root length (31.09 cm) and root volume (66.67 mL).

This study aimed to obtain the best dose of Arbuscular Mycorrhizal Fungi (AMF) and the best concentration of liquid organic fertilizer made from overripe fruits for the growth and production of soybean plants. The trial was conducted at the Experimental Farm, Faculty of Agriculture, Universitas Hasanuddin, Makassar, South Sulawesi, from June to August 2017. The research was carried out in the form of a 2-factor factorial experiment using a Randomized Blocked Design (RBD) as environmental design. The first factor was the AMF dose with three levels, namely control (0 g polybag−1), 10 g polybag−1, and 15 g polybag−1. The second factor was the concentration of liquid organic fertilizer with three levels, namely control (0 ml L−1), 15 ml L−1, and 20 ml L−1. The experimental results show that the application of the mycorrhizal fungi on the soybean plants did not have a significant effect on several growth and production components, but it has a very significant effect on the number of branches parameter. Application of AMF of 10 g polybag−1 gave the best result on parameters of flowering age, number of pods, dry seed production and weight of 100 seeds. The concentration of liquid fertilizer of 15 ml L−1 resulted in the best result on parameters of plant height, number of leaves, and flowering age.

Lampung is one of the centers for shallot development in Indonesia. The application of location-specific off-season shallot cultivation technology and the use of superior varieties is expected to be able to guarantee its availability throughout the year and overcome price fluctuations. For this reason, it is necessary to study the cultivation of off-season shallots with varieties in accordance with market demand. This activity was carried out in Tanggamus Regency, from January to December 2018. The experimental design was the Split Plot, where the main plot was the use of mulch and without mulch and as sub-plots were three shallot varieties, namely: 1. Bima Brebes; 2. Trisula; and 3. Bali Karet varieties. Each treatment was repeated four times. The data obtained were analyzed using variance with DMRT at the 5% level. The results of the study show that off-season shallot cultivation is promising to be cultivated by farmers with an average of 14.59 tonnes/ha using Bima Brebes, Trisula, and Bali Karet varieties. Bali Karet variety has good prospects to be developed and planted off-season because they are more resistant to pests and diseases and have the highest production (20.87 tonnes/ha) compared to Bima Brebes and Trisula varieties.
