For most crops, genetics are not the limiting factor to achieve high yields. It is very seldom, almost never, that a crop is given the needed environment to deliver full genetic potential. For agricultural crops, environment is climate mediated by nutrition, biology, and soil physics.
When nutrition, biology, and soil physics are managed for optimal performance, they mitigate climactic extremes and variability to an exceptional degree, and allow plants to express themselves to deliver more of their genetic yield potential.
If you want to significantly increase yields, don’t just try to improve incrementally by purchasing better genetics. Improved genetics can often deliver 5% -10% yield bumps. Mediating climate by managing nutrition, biology, and soil physics can often increase yields by 20%-50% or more. Which is worth figuring out the most?
