Summary

This research investigates the application of bio-fertilizers to improve the growth, yield, and control Fusarium wilt in red onions (Allium ascalonicum L.). The study evaluates three types of bio-fertilizers (Agrofit, Biopf, and Biotrico) combined with varying doses of synthetic chemical fertilizers. Results indicate that using a combination of 5% bio-fertilizer with 25% synthetic fertilizer significantly enhances growth quality and dry bulb weight (7.91% to 32.65% increase), compared to using 100% synthetic fertilizer. The most effective combination for boosting growth and controlling Fusarium infection involved Biopf bio-fertilizer with 25% synthetic fertilizer dosage.

Takeaways

• 😀 Red onions (Allium ascalonicum L.) are a high-value national vegetable in Indonesia, with significant economic importance.
• 😀 Excessive use of synthetic fertilizers and pesticides in onion farming has led to soil degradation and environmental concerns.
• 😀 The study focuses on the application of bio-fertilizers as an alternative to reduce chemical input usage and improve onion production.
• 😀 Bio-fertilizers contain microorganisms that promote plant growth and are essential in sustainable farming practices.
• 😀 The research tested three types of bio-fertilizers: Agrofit, Biopf, and Biotriko, combined with varying dosages of synthetic fertilizers (0%, 25%, 50%, 75%, 100%).
• 😀 The experimental design used a randomized block design with three replications of each treatment to ensure reliability.
• 😀 A combination of 5% synthetic fertilizer with bio-fertilizers improved onion growth, resulting in a 7.91% to 32.65% increase in dry bulb weight compared to the 100% synthetic fertilizer treatment.
• 😀 The highest effectiveness in promoting onion growth and controlling Fusarium wilt was achieved with the Biopf bio-fertilizer combined with 25% synthetic fertilizer.
• 😀 The combination of Biopf with 25% synthetic fertilizer showed similar biomass production to the full 100% synthetic fertilizer treatment.
• 😀 The study highlights the potential of combining bio-fertilizers with reduced synthetic fertilizer doses to enhance sustainable farming while managing plant diseases like Fusarium wilt.

Q & A

What is the main objective of using bio-fertilizers in onion cultivation?

The main objective of using bio-fertilizers in onion cultivation is to reduce the use of synthetic chemical fertilizers, enhance growth, increase productivity, and control Fusarium wilt disease.

What are the types of bio-fertilizers evaluated in this study?

The study evaluates three types of bio-fertilizers: Agrofit, Biopf, and Biotriko.

What is the significance of Fusarium wilt in onion cultivation?

Fusarium wilt is a disease that affects onions, reducing crop yield and quality, making it important to find ways to control or prevent it during cultivation.

What combination of fertilizers was found to be most effective in the study?

The most effective combination in the study was the use of the bio-fertilizer Biopf combined with 25% of the recommended dose of synthetic chemical fertilizer.

How does the combination of bio-fertilizers and chemical fertilizers affect onion growth?

The combination of bio-fertilizers and chemical fertilizers significantly improved onion growth, with an increase in onion bulb weight by 7.91% to 32.65% compared to the use of 100% chemical fertilizer alone.

What is the impact of excessive use of chemical fertilizers on agricultural land?

Excessive use of chemical fertilizers leads to the degradation of agricultural land, reducing its capacity to support healthy plant growth over time.

What research design was used in this study?

The study used a randomized block design with three replications for each treatment to evaluate the effectiveness of different fertilizer combinations.

What was the dose of synthetic chemical fertilizer used in the study?

The doses of synthetic chemical fertilizer used were 0%, 25%, 50%, 75%, and 100% of the recommended dosage.

What was the effect of the fertilizer combinations on Fusarium infection?

The fertilizer combinations, particularly those involving bio-fertilizers, significantly reduced the infection rate of Fusarium wilt compared to using 100% chemical fertilizer.

How did the use of 5% chemical fertilizer dosage compare to the full recommended dosage?

The use of 5% of the recommended chemical fertilizer dosage, in combination with bio-fertilizers, resulted in improved growth and higher biomass, comparable to the full recommended dosage of synthetic fertilizers.
