Biostimulant streptomyces sp. N2A for enhanced corn hybrid performance

Overview

The novel biostimulant Streptomyces sp. N2A has been identified as a promising agent to enhance growth and yield in corn hybrids by providing biocontrol against biotic and abiotic stresses. Previously tested in various plant species such as soybean, wheat, and maize inbreds, this bacterium has demonstrated significant potential in promoting plant growth. Current research aims to evaluate its effects on different maize hybrids, focusing on varying responses across genotypes and identifying those with optimal performance when inoculated.

Technical specifications

Key features:

• Isolated and characterized Streptomyces sp. N2A with known biocontrol properties.
• Demonstrated growth promotion in species like soybean, wheat, and maize inbreds.
• Current trials involve inoculating ERA maize hybrids to assess growth, yield, and biocontrol efficacy.
• Comprehensive analysis of flavonoid, starch, and soluble sugar content in inoculated plants.
• Measurement of photosynthetic parameters, water management, and root system development.
• Evaluation of yield by ear and kernel weight and number of kernels per ear.
• Comparative infection trials with C. graminícola to assess biocontrol efficiency.

Technology readiness level

This biostimulant is currently at Technology Readiness Level 3, indicating experimental proof of concept. Extensive greenhouse and field trials are ongoing to validate its effectiveness across different maize hybrids, which will provide insights into its commercial viability and potential agricultural benefits.
