What factors affect high yield in summer corn?
What affects high yield in summer corn? Here is an introduction to four problems that cannot be ignored in summer corn production and that have become important factors limiting high yield in summer corn: First, seed selection is not careful. Some farmers have a "bargain-hunting" mentality and buy low-priced "improved seed" from small vendors or unofficial seed sellers. Most of this seed is self-produced, the seed production process is not scientific enough, and the seed purity does not meet standards, thus causing serious yield reductions. Therefore, going to official seed suppliers and choosing improved varieties suitable for the local area is the prerequisite for achieving high corn yields.
