WALKING YOUR FIELDS

®

www.pioneer.com

The 2013 rollercoaster growing season continues with sporadic harvest progress. September and early October brought much needed mild weather and above average temperatures. Entering the third week of August, GDU accumulation was tracking 140 GDUs under the 10 year average. At that point, there was serious concern if the corn crop would reach black layer prior to a major frost. As a result of the mild fall, a majority of fields did reach black layer prior to the later-than-normal killing frost. Yield results have been mixed based on geography and weather. We cannot forget about the spring and summer we had when we evaluate yield data for 2013. Planting dates ranged from late April to early July in some areas; planting conditions during that timeframe were challeng-ing followed by mid-summer drought.

Rollercoaster Ride Continues

November 2013 - Issue 6

Analyzing Yield Data

Planting date: In many instances, plots were plant-ed much later than normal in 2013 without making changes to the maturity of the products. Earlier corn and soybean products have done well compared to standard full season products.

Corn Flowering date: Late flowering hybrids have tended to struggle in plots due to late planting dates and heat and moisture stress that occurred the sec-ond half of August as these hybrids were flowering.

Multiple Locations: Try to seek out plots that were replicated in the surrounding area. This will show some of the variables and give you a solid picture of how products performed in your area.

Multiple Years: It will be important to seek out 2012 yield data as well before decisions are made for next year. Products that shined in 2012 may not look nearly as good in 2013 based on planting and flower-ing date. Evaluate both years closely before making final product decisions for 2014. The data provided in this newsletter is from 2012 and 2013 across a wide geography to increase the number of locations.

The more hybrid test plot replications, the greater the chance the results are an accurate overview of that hybrid’s performance.
