Humikal application in one pass with sowing – a modern and efficient solution in sunflower cultivation

Experimental treatments

The following treatments were included:

  • Untreated control
  • Humikal Universal Classic Liquid
  • Humikal Universal Classic Granulate
  • Bay Premier microbial product
  • Combination treatments
Objective

The aim was to evaluate both:

  • Individual product performance
  • Potential synergistic effects of combined applications

Key results

Humikal Granulate – strongest individual plant growth response

The Humikal Universal Classic Granulate treatment showed the most pronounced effect on individual plants.

  • ~64% higher average individual vegetative biomass compared to control

This indicates a strong enhancement of early-stage individual plant development, supporting vigorous growth.

Humikal Liquid – stable biomass improvement

The Humikal Universal Classic Liquid treatment resulted in:

  • ~13% higher total vegetative biomass compared to control

This reflects a stable and positive stand-level response during early development.

 Bay Premier – positive microbial effect

The Bay Premier microbial product showed:

  • Improved germination trends
  • Positive early biomass development

This suggests that microbial activity supports early root establishment and nutrient utilization efficiency, which are key factors in plant performance.

 
Practical interpretation

Each product contributed differently to plant development:

  • Humikal Granulate → stronger individual plant growth
  • Humikal Liquid → improved stand-level biomass formation
  • Bay Premier → enhanced germination and early development

These technologies are complementary, making them suitable for integrated crop management systems where soil conditioning and microbial support work together.

Scientific note

This was a preliminary controlled environment (growth chamber) trial.

While the results are promising, they should be considered exploratory. Further:

  • replicated trials
  • statistical validation
  • field experiments

are required for stronger scientific conclusions.

Overall conclusion

In this lettuce pre-trial, all tested treatments:

  • Humikal Universal Classic Granulate
  • Humikal Universal Classic Liquid
  • Bay Premier microbial product

showed positive growth and development trends.

The study highlights the potential of combining:

  • soil conditioning technologies
  • plant biostimulants
  • microbial support systems

for modern, high-efficiency agricultural production.
