Abstract

Sunflowers have excellent prospects for future development in Indonesia. This commodity offers a variety of uses, from food and medicine to industrial use and even as a beauty product. Currently, development is focused on marginal land, particularly sandy soil. However, such land is known to have various limitations, necessitating innovations to enable its use as cultivation. One such approach is the application of fertilization technology using maggot compost and chicken manure. The purpose of this study was to evaluate the effectiveness of maggot compost and chicken manure on sunflowers in sandy soil. This study was conducted in Pasir Putih, Padang City, from June to September 2025. The design used in this study was a randomized block design with two factors and three replications. The first factor was the dose of maggot compost and the second was the dose of chicken manure. The results showed that the application of chicken manure and maggot compost at various doses resulted in increased growth and yield of sunflowers in sandy soil with each dose increase. Maggot compost at a dose of 20 g/plant and chicken manure at a dose of 30 g/plant had an interaction on plant height. Meanwhile, at a dose of 20 g/plant of chicken manure fertilizer and 15 g/plant of maggot compost, there was an interaction on the number of sunflower seeds.

Abstract

Yanti Y, Warnita, Reflin, Nasution CR. 2018. Characterizations of endophytic Bacillus strains from tomato roots as growth promoter and biocontrol of Ralstonia solanacearum. Biodiversitas 19: 906-911. Bacterial wilt caused by Ralstonia solanacearum is the most damaging vascular pathogens in tomato and many other crops in tropical, subtropical and warm temperate areas of the world limiting its production. Biological agents such as Plant growth Promoting Rhizobacteria (PGPR) is considered as a potential biological control agent for the suppression of plant diseases such as bacterial wilt. Bacillus spp. are one of the most potential genera of PGPR group used for controlling pathogens and promoting plant growth because of their spore-forming ability which increases their adaptation to the environment. The aims of the research were to isolate Endophytic Bacillus isolates, to characterize its ability as plant growth promoter and pathogen controller, and to identify its molecular genetic using 16S rRNA. Bacillus strains were isolated from healthy tomato roots. All Bacillus spp. strains acquired from isolation were then screened directly on plants in completely randomized design experiments with 3 replications. All potential strains were screened and identified using 16S rRNA with 27F and 1492R primers. Results showed that out of 15 obtained isolates, 6 of them showed a good ability to both promote growth and control R. solanacearum. All isolates were identified as B. Pseudomycoides strain NBRC 101232, B. cereus strain CCM 2010, B. toyonensis strain BCT-7112, B. anthracis strain ATCC 14578, B. cereus strain JCM 2152 and B. cereus ATCC 14579.

Abstract

Yanti Y, Warnita, Reflin, Busniah M. 2018. Indigenous endophyte bacteria ability to control Ralstonia and Fusarium wilt disease on chili pepper. Biodiversitas 19: 1532-1538. Bacterial wilt and Fusarium wilt caused by Ralstonia syzigii subsp. indonesiensis and Fusarium oxysporum f.sp. capsici (Foc), respectively are the most damaging vascular pathogens in chili pepper (Capsicum annuum L.) and many other crops limiting their production, worldwide. Various strategies have been developed to control wilt pathogens including the application of chemical pesticides, which generally considered as the most effective and fastest strategy for plant disease management. However, effective chemicals for wilt pathogens of chili pepper plants are not available, yet. Endophytic bacteria considered as one of options to control vascular wilt disease because of its ability to live and colonize in internal roots of plants. Previous research has been done to select endophytic indigenous bacteria isolates which can promote growth rate of chili pepper. The purpose of the research was to identify the selected indigenous endophyte bacteria isolates acquired from our previous study using 16S rRNA identifications and to screen the selected endophytic indigenous bacteria to control both R. syzigii subsp. indonesiensis and Foc. Results from 16S r RNA analysis showed that all of 9 isolates were identified as Bacillus spp., such as Bacillus cereus ATCC 14579, Bacillus pseudomycoides strain NBRC 101232, Bacillus toyonensis strain BCT-7112, Bacillus thuringiensis strain ATCC 10792, Bacillus weihenstephanensis strain DSM 11821, Bacillus mycoides strain 273, Bacillus cereus strain NBRC 15305, Bacillus bingmayongensis strain FJAT-13831 and Bacillus manliponensis strain BL4-6. Our results showed that most of endophytic bacteria isolates application could control both bacterial and Fusarium wilt diseases. Six out of nine isolates can suppress R. syzigii subsp. indonesiensis without developing any symptoms and five isolates could suppress symptoms of Foc. Isolates Bacillus pseudomycoides strain NBRC 101232 Bacillus thuringiensis strain ATCC 10792 and Bacillus mycoides strain 273 were potential for control Foc and R. syzigii subsp. indonesiensis in chili pepper.

Abstract

Yanti Y, Warnita, Reflin. 2018. Short Communication: Development of selected PGPR consortium to control Ralstonia syzygii subsp. indonesiensis and promote the growth of tomato. Biodiversitas 19: xxxx. A microbial consortium is a group of different species of microorganisms and acts as a community. Combinations of biocontrol strains are expected to have a better result to suppress multiple plant diseases. Our previous research had selected four plant growth promoting rhizobacteria (PGPR) strains from chili (B. pseudomycoides strain NBRC 101232, B. cereus strain CCM 2010, Bacillus toyonensis strain BCT-7112, Serratia nematodiphila strain DZ0503SBS1) and three strains from tomato (Bacillus pseudomycoides strain NBRC 101232, Bacillus toyonensis strain BCT-7112, Bacillus thuringiensis strain ATCC 10792 ) which had ability to promote growth and control Ralstonia syzygii subsp. indonesiensis indigenously. The strains were used in the development of PGPR consortiums to increase their ability for biocontrol agent of Ralstonia syzigii subsp. indonesiensis and promoting the growth of tomato. Results showed that not all strains had good compatibility to grow together. Ten consortiums were developed based on their compatibilities. All consortiums exhibited the capability to reduce bacterial wilt disease development and also promote the growth of tomato. The consortium consisted of Serratia nematodiphila strain DZ0503SBS1, B. cereus strain CCM 2010, Bacillus aryabhattai strain B8W22 and Bacillus cereus strain IAM 12605 resulted in the best ability to reduce disease development and promote growth and yield of tomato.

Abstract. Yanti Y, Hamid H, Reflin, Warnita, Habazar T. 2019. The ability of indigenous Bacillus spp. consortia to control the anthracnose disease (Colletrotricum capsici) and increase the growth of chili. Biodiversitas 21: 179-186. Anthracnose disease caused by Colletotrichum capsici can reduce yields of chili up to 80%. The control of anthracnose disease is generally carried out using synthetic fungicides. However, the use of these fungicides can pollute the environment and harm human health. One alternative control that needs to be developed is the use of Bacillus spp. as a biocontrol agent. The study was conducted to obtain an indigenous Bacillus spp. consortium that compatible as a biological agent for the control of the anthracnose diseases and promoting the growth of chili plants. The experiment was arranged as a completely randomized design, consisted of three stages, namely: 1) inhibitory test of indigenous Bacillus spp. against C. capsici in vitro, 2) compatibility test of indigenous Bacillus spp. and 3) Test of indigenous Bacillus spp.consortium for controlling C. capsici and promoting the growth of chili. The results showed that eight species of indigenous endophytic bacteria could inhibit the growth of C. capsici in vitro. All combinations of indigenous Bacillus spp. were compatible for controlling C. capsici. Four combinations of Bacillus spp. were able to increase the growth of chili plants. K1 consortium (Bacillus pseudomycoides strain SLBE 3.1 AP, Bacillus thuringiensis strain SLBE 2.3 BB, Bacillus toyonensis strain AGBE 2.1 TL) was the best consortium for controlling C. capsici.
