Sowing date: 12/05/2022
Today: 28/07/2022 (78 days from sowing)
Current stage: R1
Site: Ontario, Canada

Finally corn reached to R1. Now we can see corn silk will appear.

Also, we regard corn developmental stage as R1 (silking) when tassels appears. It’s very important silking and tasseling are synchronized timely for successful pollination and fertilization (It would determine final yield).

Environmental stresses (i.e. drought or heat, etc) would cause unsynchronization between silking and tasseling. When one appears first and another one appears so late, successful pollination would be limited.

So, now it’s R1 stage and we harvested some plants according to our plans. After harvesting, we separated ears from the stalk. It would be important to figure out dry weight partitioning from the total dry weight as it provides many physiological concepts.

Harvesting process took much more time we expected as some unexpected event occurred.

What is an expert? In a dictionary, it defines “a person who has a comprehensive and authoritative knowledge of or skill in a particular area,” but I think an expert is a person who solve the problem efficiently he or she confronts. Only having knowledge would not be enough.

Finally we finished at 21:00. However, agronomy research is always fascinated!!
