I believe that two factors had significant impact on this year’s corn. Factor 1 First is the weather. Too much rainfall early and then a lack of rainfall at the end of the growing season, Table 1. That 0.75 inch rainfall in August really hurt! Table 1: Weather at the Agronology 10 Research Center, Walcott, IA…

After reviewing the top 10 yields from our 2013 corn Critical Considerations data set, I have made the following observations. Observations Average yield for this 10 plot group is 242.13 Bu/A. All 10 corn plots had a fall dribble N-P-K applied last fall. 8 of the 10 fall dribbled fertilized plots had a 29-55-85 applied….

With much of the 2013 soybean crop harvested, what can I comment on? Observations I believe that soybean planting date did affect the 2013 soybean crop. Our soybean crop planted May 1, 2013 yielded approximately 70 Bu/A. Some varieties weathered the stresses of 2013 better than others. From our Soybean Management II experiment, we observed the following…

Wow! My corn and soybean harvest was completed on September 26. Observations Harvest lasted almost 4 days and we harvested approximately 30 acres of crop. Our top soybean yield in 2013 was almost 90 Bu/A, which is the 5th highest individual yield since 1994 at the Agronology 10 Research Center in Walcott, IA.
As the end of August draws closer, my concerns are on our developing crop. Observations First, how much rainfall have you had during the month of August? Our 30 year average rainfall for August is 4.41 inches. At the Agronology 10 Research Center at Walcott, the rain gauge has been stuck on 0.75 inch of rainfall since…

While much of our current attention for crop development is on corn, let’s not forget our soybean crop. Items to consider for the soybean crop On the longest day of the year, June 21, how much leaf area was present in your soybean field? The more leaf area, the better the prospects are for higher…

How far along is my corn crop this year? For corn, remember that tasseling time (date) plus 60 days on average will give us approximately 32% moisture corn. If I add another 10-to-14 days to further field dry the crop then harvest of 25% to 27% moisture corn could be possible. Example For instance, my corn…

From a short historical prospective, I am including the following data from our Agronology 10 Research Center at Walcott, Iowa. The norms are a 30 year average from the US Weather Service. Table 1 Weather Data for 2010 thru 2013 Time Period (Months) Rainfall (Inches)______________ 1 April – 31 July__ Norm 2010 2011 2012 2013 16.08 28.70 …

It is time to begin evaluating your corn fields now. After the corn silks have turned brown, we can easily look at the ear girth—number of rows of kernels. This maximum girth aspect for the corn is determined at V5 to V6 growth stage—8 to 12 inch tall corn. From the maximum girth potential, the actual…

Today, July 22, I looked at 111 day corn with brown silks in both corn-on-corn and corn-on-soybean ground. The girth aspect for both ears was excellent with 18and 20 rows around, but the corn-on-corn was exhibiting some unfilled ovules while the corn-on-soybean was entirely filled. Observations In an area where water moved across the field after…
