1st Sweet Corn Semi-FAIL - Insufficent Pollenization & Other Causes

Google defined the causes with first ENTER question but FARM PROGRESS is a great web site for all things ... well, farming: https://www.farmprogress.com/corn/what-causes-poor-kernel-set-in-corn- Link for more in-depth info.

Suspect the causes noted vs. heat stress or insect damage to tassles, none of which were a problem. There WERE plenty of rainy and cooler days for these early ones. We'll see ... current corn crop is in about half a dozen stages of growth due to manual planting over a couple months. Seems corn, the only grass species that cannot now survive without human intervention, relies on dusting its pollen down from the tassles onto the female bits below so affected by humidity, rain and a freak'n strong breeze. More notes:

1. Farm Progress shows there's a loss formula when this happens but likely moot when dealing with under a dozen plants at this stage. Mitigates the disappointment quite a lot, too.

2. Same thing noticed on debut plants last year. This time was only in this cattle tank and planted about the same time if later. Weather was noticeably hotter and drier last year. Only yielded about 12 cobs; 60% this way but wow, the 40% made up for it all. THOSE were perfect yet in same site.

3. Entire crop from a single old cob of a locally-valued 60-Day hybrid. Later ones seem to be growing faster (duh. warmer). May be some issue with that individual seed source cob but as others are 100%, the pollen deal seems right.
