“…The low productivity of TSS shallots was also influenced by the lack of production inputs used, both organic and inorganic fertilizers, and the spacing was not optimal. The increased growth and yield of TSS shallots can also be accomplished by the application of salicylic acid as was found [22].…”

The aims of the study were: 1) to determine the seeding performance, growth and yield performance of shallot cultivation from TSS (True Shallot Seed), 2) to determine farmers' perceptions of TSS shallot technology, and 3) to analyze the financial of TSS shallot farming in Gorontalo. This TSS shallot applied study was conducted in Gorontalo in 2019. To find out the best seeding technique using a Randomized Block Design (RBD) method with 6 treatments and 10 replications. Farmers' perceptions were analyzed using percentage techniques using a Likert scale based on 30 respondents. Farm financial was analyzed descriptively by calculating revenue, cost and R/C ratio. The results showed that the best TSS shallot seeding was obtained in raised beds with paranetal cover with a growth percentage >90 percent. The growth percentage of TSS after transplanting reached >80 percent with a productivity of 4.9 tonnes/ha. The average farmer's perception of TSS shallot technology showed that the TSS shallot cultivation technology produces tubers of excellent quality, saves seed costs, and farmers are interested in implementing it again. The results of farming financial analysis showed that the TSS shallot farming had an R/C ratio of more than 1 which means it is efficient to implement.

“…The study results found that the incidence in control plants were still relatively low and might be related to the virulence of the pathogen used. Wijoyo et al (2020) showed that the incidence of moler disease on control plants from F. acutatum inoculation was only about 28.33% to 34.03%.…”

“…F. acutatum isolates were grown on Potato Dextrose Agar (PDA) medium for seven days, then the spores were harvested and suspended to obtain a spore density of 10 6 CFU/ml. Pathogen inoculation was carried out by applying 10 mL of pathogen suspension to each plant during shallot planting (Wijoyo et al, 2020).…”

Plant Growth Promoting Rhizobacteria has been known for its ability to induce plant resistance on shallot against twisted disease. Its ability as a bioprotectant agent is estimated to be comparable to the efficacy of Trichoderma which is currently widely used as a biological control agent.. This study aims to determine the content of jasmonic acid, salicylic acid, peroxidase, and disease suppression in shallot by application of Bacillus velezensis B-27, Bacillus cereus RC76, and application with combination of both rhizobacteria. The application was carried out with tuber dipping for 30 minutes in each treatment with a bacterial density of 108 CFU mL-1. Application using Trichoderma was used as the comparison treatment, and the control plot was not given any treatment. Pathogen inoculation was carried out simultaneously as planting using Fusarium acutatum with a spore density of 106 CFU mL-1. The jasmonic and salicylic acids content was measured using the High-Performance Liquid Chromatography method, and the peroxidase content was determined using the spectrophotometric method. Disease suppression was measured at 10-day intervals. The results showed that treatment with Bacillus cereus RC76 increased jasmonic and salicylic acid levels, while application with Bacillus velezensis B-27 showed the highest level of peroxidase. Treatments with Bacillus spp. were able to suppress twisted disease by 72.2% to 100%. This study demonstrated that application Bacillus spp. suppressed twisted disease on shallot and increased the jasmonic and salicylic acid content as induced resistance mechanism against pathogens.

“…This condition is due to each variety having specific genetic characteristics in adapting to the growing environment, especially the availability of nutrients so that varieties will respond differently to growth [24] because each variety has different adaptability [5]. TSS varieties significantly affected plant growth [25].…”

The success of shallot cultivation in vertisol soil is influenced by the use of seeds and the application of organic matter. This aim of this study aims to determine was to the effect of local organic matter on vertisol soil on the growth and yield of three true shallot seed (TSS) varieties. The research was carried out in Plembutan, Playen, Gunung Kidul. The research was conducted from May-August 2021. The research method used a Split Plot Design with 3 replications. The main plot consists of types of local organic matter (B), consisting of B1 = Cow, and B2 = Goat, B3 = Chicken. While the sub-plots were Varieties (V), consisting of: V1 = Maserati, V2 = Sanren, and V3 = Lokananta. Plant height, number of leaves, number of bulbs per clump, dry bulb weight per clump, bulb diameter, and productivity were all measured. The data was analyzed using variance and DMRT 5%.The results showed that the type of local organic matter did not significantly interact with the TSS variety. Plant height, number of leaves, number of tubers per clump, dry tuber weight per clump, tuber diameter, and productivity were not affected by the organic matter and variety treatments. The type of local organic matter from cows produces the highest growth and yields, followed by goats and chickens. The lokananta variety produced the highest productivity, followed by Sanren and Maserati.
