Abstract
Timing and Positioning of Simulated Hail Damage Effects on Wheat Yield in Kansas
Highlights
Winter wheat is often subjected to several environmental yield-reducing events throughout the growing season in Kansas
A total of 12 hail damage treatments including six different timings during the growing season and two different positionings relative to the flag leaf were evaluated in a trial conducted in Manhattan, KS, during the 2015-16 growing season
Wheat yield loss due to stem bending treatment ranged from 5.8 bushels per acre (9.0%) for treatment imposed below the flag leaf during hard dough to as much as 23.7 bushels per acre (36.7%) for treatment imposed during the milk stage, above the flag leaf
Summary
Winter wheat is often subjected to several environmental yield-reducing events throughout the growing season in Kansas. One of the most devastating weather events to wheat grain yield is hail. Hail damage might fully compromise a particular field’s productivity, and a solid estimation of hail damage can help producers and crop insurance agencies make better decisions regarding maintaining a hail-damaged crop for grain yield. The objectives of this project were to understand the wheat yield losses associated with stem positioning and timing of stem bending to simulate hail damage, and to improve the yield loss estimates performed when assessing hail-damaged wheat fields
