Abstract

This investigation aimed to study the response of chili to the application of biochar and vermicompost, and to find the combination that produced the best growth and yield of red chili. The trial was conducted at the Teaching and Research Farm, Faculty of Agriculture, University of Jambi from May 2023 through to October 2023. The treatments tested were the application of five different soil ameliorant, i.e. 100% biochar, 75% biochar + 25% vermicompost, 50% biochar + 50% vermicompost, 25% biochar + 75% vermicompost, 100% vermicompost, and 100% NPK fertilizer.  The experiment was arranged in a completely randomized block design with four replications each consisted of 14 plants (7 of them were taken as sample plants). The results showed that the application of biochar along with vermicompost could increase the growth and yield of red chili. The use of 25% biochar + 75% vermicompost resulted in the highest growth and yield, indicated by average fruit number of 58.75 per plant and fruit weight of 173.71 g per plant, or 6.95 ton·ha-1.  Thus, our study proved that the application of biochar and vermicompost is crucial to improve drought-tolerance of red chili cultivated in dry land.

Abstract

Shallot is one an important of vegetable comodity, both in economic value and nutrition ingredients. One of an effort to support the increasing of shallot yield with plantation technology by giving palm oil ash fertilizer and micorrhiza. The experiment we studied to find out the effect of palm oil ash fertilizer and michorrhiza with different doses on yield of shallot. The experiment used Randomized Block Design consisted 4 doses of palm oil ash a0 : 0 ton-1ha,a1 : 2 ton-1 ha, a2 : 4 ton-1 ha, a3 : 6 ton-1 ha and michorrhiza ,m1 : 0 g plant-1, m2 : 5 g plant-1, m3 : 10 g plant-1 m4 : 15 g plant-1 with 3 replication. Observation parametrs include plant height, number of leaves per clump, number of tubers per clumb, fresh tuber weight per clumb, dry tuber weight per clump, average weight per tuber and average tuber weight per hectare. The data were analyzed using a Randomized Block Design at the 5% level using DStaat version 1.514 and SPSS Statistic 22, and then differences between treatments using the LSD (Least Significant Difference ) test at the 5% level test. The results show that dose of 2 ton-1 ha oil pam ash fertilizer alone has a very significant effect on height plant at 5,6 and 7 weeks after planting and the number of leaves at 3,4 and 7 weeks after planting, wet and dry tuber weight and average weight per dry tuber and weight per hectare.

Abstract

Increasing Production of Integrated-Vegetable and Fish in the Biofloc-Aquaponic System in Tanjung Johor Village, Jambi City. Tanjung Johor is a fish-producing center in Jambi City. However, the biofloc pond of Sekintang Dayo Farmers Group was minimally managed, so the fish yield and the farmer's income is low. The technology that was the potential to be applied was biofloc-aquaponics. Biofloc-aquaponics technology is a technology in agriculture which is integrated vegetable and fish cultivation. This technology was considered adaptive and effective in Tanjung Johor Village because this area was a populated residential area, limited land availability, prone to flooding, and the community still faced food sufficiency problems. The main principle of this technology was to conserve soil and water and increase farming efficiency through the use of nutrients from fish feed residues as a nutrient source for plants, so it is environmentally friendly. The objective of this community service was to overcome problems in the community, especially members of the Sekintang Dayo farmer group, through simple environmentally friendly technology, namely biofloc-aquaponics in integrated fish and vegetable cultivation. This activity used Participatory Rural Appraisal (PRA) method, where members of the Sekintang Dayo Fish Farmer Group interact with each other to identify the problems they face and find appropriate solutions. Group members actively followed, applied, and developed technology of biofloc-aquaponics cultivation. The program evaluation at the final stage of this activity showed an improvement in farmers' understanding and skills from 49.29% to 97.14%. The farmer group members are admitted to develop the knowledge gained and will design their own biofloc-aquaponic device by utilizing existing resources.
