STUesday on a Thursday – Hybrid Maturity Switches Based on Long-Term Research

- Hybrid Maturity Switches Based on Long-Term Research Crop Insights by Mark Jeschke and Steve Paszkiewicz Summary Introduction Pioneer Long-Term Corn Planting Date Studies Hybrid Maturity Switching Central Corn Belt North-Central Corn Belt Northen Corn Belt Far Northen Corn Belt Grain Moisture Corn Adjusts to Later Planting Agronomic Tips for Wet Spring Weather Summary When rainfall significantly delays field and planting operations, switching to early maturity hybrids is sometimes needed to ensure timely crop maturation. To help guide these decisions, Pioneer researchers...

STUesday – Delayed corn planting considerations

- Delayed corn planting considerations – When do I switch corn maturities? Much of the Corn Belt is seeing delayed corn plantings due to first, cold soil temps and then excess soil moisture. It seems like the closer we get to May 1st there are more conversations and questions of when do I start switching to earlier maturities.  I still think for the majority of the Corn Belt the optimum planting date is from April 15th to May 15th with your...

Soil Temperature and Corn Emergence

- Soil Temperature and Corn Emergence Crop Insights by Maria Stoll1 and Imad Saab2 Summary Introduction Optimal Temperature for Early Corn Growth Genetic Differentiation for Emergence in Cold Soils Timing of Cold Stress Impacts Germination Soil Temperature Fluctuations and Emergence Impact of Crop Residue on Soil Temperature Tips to Help Mitigate Early-Season Stress Effects on Emergence Additional Resources Summary Corn is a warm-season crop. Germination and emergence are optimal when soil temperatures are approximately 85 to 90 F. Cool conditions during planting impose...

STUesday – When is it time to plant?

- When is it time to plant corn?   When is it time to plant corn, is always one of the hardest questions to answer in today’s world of extensive early vigor testing and seed treatments.  Farmers today have been taught that in general the earlier you plant the better off your yields seem to be in the fall.  The exception has been the growing season of 2014 when soil temps remained cold, air temperatures were extremely variable, soil remained damp...

Considerations for Managing Ear Drop in Corn

- Considerations for Managing Ear Drop in Corn Conditions That Can Cause Ear Drop Moisture stress at silking:  The shank develops quickly during a two-week period surrounding pollination. Severe drought and heat stress at that time can hinder shank development. Favorable weather after drought stress:  Ear drop is most common when drought/heat stress during ear and shank development is followed by favorable weather during grain fill. Weak shanks formed during pollination are unable to hold on to heavier ears. Rapid dry...

STUesday – Consideration for Early Planted Corn

- Overview Farmers often plant corn very early to increase yield potential and to avoid weather delays late in the season. Early planting offers potential advantages, but it also carries risks related to cold injury and damage from pests. Critical factors for deciding how early to plant include current soil temperature and moisture conditions and the near term weather forecast to optimize the planting “window”. Ultra-early planted corn may require up to four weeks to emerge, depending on soil and weather...

STUesday – Putting Variable-Rate Seeding to Work on Your Farm

- Putting Variable-Rate Seeding to Work on Your Farm Crop Insights written by Mark Jeschke, Ph.D.1, Paul Carter, Ph.D.2, Phil Bax3, and Ryan Schon4 Summary Introduction Developing a Variable-Rate Strategy Selecting a Hybrid and Seeding Rates Building a VRS Prescription Evaluating VRS Prescription Effectiveness Interpreting the Results Sources and Additional Resources Summary Extensive field research has documented the value of planting higher corn seeding rates in more productive field areas and decreasing rates where productivity is lower. To maximize variable-rate seeding...
