Posted 1/5/2021 by Bob Nielsen, Purdue's Extension Corn Specialist. Achieving high yields in corn requires attention to detail and a focus on agronomic fundamentals. This video is Part 2 of a 3-part series, created from the overall longer version of the presentation that was initially posted 11/30/2020.

I had used most of your Fundamentals to make field average of 200 bu/ac in my farming operation in the 1960's. I had a Soil Science degree in those years while starting to farm. Back then there were not many Midwest farmers who made 200 bushel yields. We were planting up to 34,000 and they used 10,000 less. One exception was from Decatur Illinois area. It was good to talk to them at the awards banquets. In Texas we were much less traditional than the Midwest as this was a new corn area.

Thanks for the great presentation! What’s the most important yield component number of kernels harvested or kernel weight?

@purduecornguy 3 года назад

That is a difficult question to answer. Both components are obviously important and growers should aim to optimize each one in order to maximize yield. It's useful to remember that kernel number per ear influences kernel weight inversely, meaning that ears with high kernel counts typically have lower weight per kernel, and vice versa.

Sir how many kilos you produce per hectare..may we know .bec here in our country we calculate pwr hectre in kilos..per sacks also .we produce 10k-16 tons per hectare ..may u know your calculations Sir..Thanks..im interested for your teaching in maize and technique..it can helps us a lot as a millenial farmers..

To convert corn grain yield in bushels per acre to kilograms per hectare, multiply by 62.9. For example, 200 bushels per acre = 200 x 62.9 = 12,580 kilograms per hectare = 12.580 tons per hectare.
