Dying light the following drought4/27/2023 When estimating corn that is very short, 1-3 feet tall, this estimate is often high.įor cornfields with no ear development that are losing leaves and not unrolling at night, the yield potential will be likely low- from 0-50 bushel/acre or so. An estimate of wet (70% moisture) silage yield is about 1 ton per foot of height of corn without ears or poorly pollinated ears. A rough estimate of the potential grain yield can be obtained using the kernel count method (see "Estimating Corn Yields" below). Drought stress is most severe when it occurs within two weeks before or after silking. Yields will be variable depending on the timing and severity of the drought. Estimating yield potential of drought stressed corn Livestock producers should begin to assess winter feed inventories and explore opportunities for purchasing corn silage, western hay, or other forages. Check with your Crop Insurance representative or FSA office before harvesting the crop. In the most severe cases, however, drought stress can result in the need for an early salvage harvest for silage.Īs the drought progresses, consider identifying ways to market your crop as silage, since returns are often greater than harvesting for grain. Usually droughts in Pennsylvania are short term in nature and the main effects are reduced grain and silage yields. This allows you to begin to consider other options for harvesting or meeting feed needs well in advance. The condition and yield potential of the crop should be monitored as the season progresses. If you're faced with a crop of drought-stunted corn, consider some of the ideas below in managing this kind of crop. Fortunately, our livestock-based agriculture means we have many ways to salvage corn in our state. Although we can do little to influence the weather, we can make management decisions that minimize the impact of the drought on the utilization of the crop. Drought and its effects are often part of growing corn in Pennsylvania.
