Southeast WI | In my 20 plus years of crop consulting and running trials I have found it difficult to visually pick up on a 10 to 20 bpa difference in yield. And this year it was so miserable out there with barely ears formed on some plants you couldnt reasonably do any yield estimation or see any differences. I have a pic with my atv parked next to the field shortly after pollination and the atv handlebars are as tall as the corn. I think i mentioned earlier that I had another starter plot trial we abandoned after harvesting. The poorest areas pollinated later and those spots had 130 bpa corn compared to half that yield where the soil was good. Just a timing issue similar to your fertilizer comments. Out in this field we really couldnt tell how successful pollinatin was until early August after it started raining.
Have you seen negative results very often in all the work youve done? I've never been to no-till conference but thinking of going this year and I wouldnt mind sitting down and talking cover crops. | |
