Effectiveness of Different Pseudomonas fluorescens Doses in Seed Treatment to Improve Resistance of Red Chili (Capsicum annuum L.). In: Herlinda S et al.

Soaking chili seeds using antagonistic bacteria Pseudomonas fluorescens is thought to be able to increase chili resistance to pests and plant diseases. This study aimed to test the effectiveness of soaking chili seeds using antagonistic bacteria P. fluorescens to increase resistance as well as the growth and production of red chili. This study was conducted at the Agro Training Center (ATC) in July-October 2024. This study was designed using a Randomized Block Design (RBD) by testing the dose of seed soaking in P. fluorescens solution, namely 0, 3, 6, 9, and 12 mL, with each treatment repeated six times. Observed variables included plant height, number of leaves, number of fruits, and the presence of arthropods. Data were analyzed using ANOVA at the 5% level, which was then further tested using the Least Significant Difference (LSD) at the 5% level. The results showed that treatment with a dose of 3 mL provided optimal results on the vegetative and generative growth of chili plants and indicated ability to produce enzymes that facilitate the absorption of P elements in the soil, while a dose of 9 mL tended to reduce the population of arthropods Cheilomenes sexmaculata, Syrphidae, Coccinella transversalis, Acraea violae, Metaleptea brevicornis, Amblytropidia mysteca, Apis cerana, and Aphis gossypii. The use of Pseudomonas fluorescens as a seed treatment has proven to be an environmentally friendly and effective biological strategy in increasing the growth and resistance of red chili plants.]]>
