Bioformulated microbial solution to increase potato crop yield and quality
A bioformulated product combining plant growth-promoting rhizobacteria and biocontrol microorganisms with organic matter, applied to potato cultivation to increase yield, tuber size, and harvest quality. Validated over four production cycles in commercial plots across Mexico.
Overview
This solution is a bioformulated agricultural input designed to increase potato crop yield, tuber size, and overall harvest quality. The formulation combines plant growth-promoting and biocontrol microorganisms with organic matter derived from worm leachate, along with macro and micronutrients. It is intended for application at planting and during key stages of crop development, including tuber initiation and early tuber filling, delivered through irrigation systems.
The product addresses the need for sustainable agricultural tools that improve productivity while maintaining phytosanitary quality. By leveraging beneficial rhizobacteria, the solution supports plant growth regulation and helps reduce the impact of phytopathogenic microorganisms, contributing to higher return on investment and improved harvest value for potato growers.
Technical specifications
Key features:
- Microbial composition: Includes Bacillus subtilis, Azospirillum brasilense, and Pseudomonas fluorescens, selected for their plant growth-promoting and biocontrol functions
- Organic matter base: Incorporates worm leachate as a source of organic matter to support microbial activity and soil health
- Nutrient enrichment: Contains macro and micronutrients to complement plant nutrition during critical growth stages
- Application protocol: Applied at planting and through four additional applications during plant development and growth via irrigation systems
- Crop compatibility: Tested on potato varieties for both fresh market and snack industry applications
- Delivery format: Liquid formulation compatible with standard irrigation methods for ease of integration into existing crop management programs
Benefits demonstrated in field trials:
- Increased production per hectare compared to untreated plots
- Higher percentage of premium tuber calibers
- Equivalent or improved phytosanitary quality in harvested tuberceles
- Greater return on investment and harvest value
Technology readiness level
The bioformulated solution has been validated over four production cycles from 2017 to 2021 in commercial potato plots across multiple agricultural regions in Mexico. Trials covered both fresh market and industrial snack varieties, confirming consistent performance in yield improvement, tuber sizing, and quality outcomes.
Future validation plans include expanding the number of commercial trial plots across diverse soil types, climates, and planting dates in Mexico. These expanded trials will further evaluate the formulation's performance under varying doses, management practices, and storage conditions to refine application recommendations and confirm broad adaptability.
