Biofertiliser for peppers can do more than help the planet; it can also lift fruit nutrition and colour. In our trial we compared standard fertilisers with three BactoTech’s bacterial biofertilisers on two commercial farms. We tracked key quality markers in the harvested fruit. Overall, this side-by-side setup shows clear, practical results for real-world growing.
Key findings at a glance
Vitamin C went up. The average rose from 169 to 181 mg/100 g. In the best case, it reached 197 mg/100 g. So, shoppers get more of a nutrient they value.
Carotenoids went up. Totals rose from ~65 to ~86 mg/kg. At peaks, two formulas hit 95 mg/kg and 90 mg/kg. Therefore, colour looked brighter and the fruit felt fresher.
Core traits stayed steady. The biofertilisers lifted nutrition, yet yield and sugars held firm. Therefore, you keep market size and taste while gaining a clear health boost.
Why these gains matter
Carotenoids add colour and antioxidant power. They include beta-carotene and capsanthin.
Also, vitamin C supports nutrition and longer shelf life.
When these go up, peppers look better and stay fresh longer.
Importantly, you gain this without giving up yield.
In short, higher carotenoids and vitamin C mean better fruit and stronger value for growers.
Study at a glance
- Sites: Two commercial pepper farms.
- Treatments: Three BactoTech bacterial biofertilisers vs a conventional fertiliser control.
- Measures: Vitamin C (L-ascorbic acid) and total carotenoids in harvested fruit.
- Outcome: Across both sites, biofertiliser programmes consistently outperformed the control on nutrition metrics, with two formulations showing the strongest carotenoid gains.
Practical takeaways for growers
- Pair biology with minerals. Add a Bacillus-based biofertiliser to your usual fertiliser plan. As a result, antioxidants can rise while yield stays steady.
- Use the market edge. Higher vitamin C and richer colour support premium pricing and repeat buys. Therefore, include these numbers in specs and buyer chats.
- Measure and prove it. Track vitamin C and carotenoids at set points. Then, share the data with retailers and customers to show clear quality gains.
Summary
BactoTech’s bacterial biofertiliser for peppers raised vitamin C and carotenoids across two farms. As a result, peppers gained clear nutrition and colour benefits. Meanwhile, core traits like yield and sugars stayed steady. Therefore, growers get better-looking, better-for-you peppers. In short, you have a stronger story to share with buyers.
