Innovation Solution
Application of Methylobacterium isolates such as NLS0807, NLS0662, NLS0648, and NLS0109, or combinations thereof, to corn plants or seeds, along with additional components like adjuvants and fungicides, during specific growth stages to enhance yield.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional agricultural methods are used for improving corn yield, then existing productivity levels are maintained, but the potential beneficial properties of Methylobacterium bacteria are not utilized
Solution Approach 1:
The patent utilizes Methylobacterium bacteria that naturally possess beneficial properties for plant growth, such as nitrogen fixation and production of plant growth-promoting substances. The bacteria serve themselves by utilizing one-carbon compounds from the atmosphere and converting them into beneficial compounds for the plant, reducing the need for external inputs like fertilizers and pesticides.
Solution Approach 2:
The Methylobacterium bacteria act as intermediaries between the atmosphere (one-carbon compounds) and the corn plant. The bacteria convert atmospheric methane and methanol into forms that benefit plant growth, effectively mediating the transfer of nutrients and growth-promoting substances from the environment to the plant.
2Productivity
If Methylobacterium isolates are applied to enhance corn yield, then significant yield increases are achieved, but the complexity of the composition and application process increases
Solution Approach 1:
The patent combines multiple Methylobacterium isolates (NLS0807, NLS0662, NLS0648, NLS0109) into a single composition that can be applied together. This merging of multiple beneficial strains into one application simplifies the overall process while maintaining the synergistic benefits of each isolate.
Solution Approach 2:
The Methylobacterium composition serves multiple functions simultaneously: it acts as a biofertilizer, biopesticide, and plant growth promoter. This multi-functionality reduces the need for separate applications of different agricultural inputs, thereby simplifying the overall management complexity.
3Productivity
If Methylobacterium composition is applied at multiple growth stages, then yield enhancement is maximized, but the time and labor required for application increases
Solution Approach 1:
The patent applies the Methylobacterium composition at the seedling stage (V3-V5) before the plant enters its most demanding growth phases. This preliminary action ensures that the bacteria are established in the rhizosphere early, allowing them to continuously provide benefits throughout subsequent growth stages without requiring repeated applications.
Solution Approach 2:
The Methylobacterium bacteria establish continuous beneficial activity in the rhizosphere, providing ongoing nitrogen fixation, phytohormone production, and pathogen suppression throughout the corn growth cycle. This continuous action eliminates the need for multiple discrete applications, reducing time and labor requirements.
