These values are multiplied to generate an estimate of number of kernels per acre and should be relatively accurate, if you do your part. In order to estimate yield, you must also integrate kernel weight into the calculation. The problem with this method or any other variant for estimating ...

Nelson said he has reduced his expectation for the corn crop to just 12.053 billion bushels, the lowest since 2006. He also expects the corn yield per acre is at around 137.2 billion bushels per acre currently, and that it could fall to 129.1 over the next couple of weeks. The USDA last...
average. These data show that it is possible to increase corn yields per acre by increasing individual plant yield as opposed to plant density; however, this has not been achieved on a wide scale. There is no guarantee that current trends will continue into the future; however, it seems ...
This study investigates whether coupling crop modeling and machine learning (ML) improves corn yield predictions in the US Corn Belt. The main objectives are to explore whether a hybrid approach (crop modeling + ML) would result in better predictio
One dropped ear per 100 feet of row or two corn kernels per square foot or equals about 1 bushel per acre yield loss. The bottom line is that the longer corn stays in the field, the greater the likelihood of substantial field losses and complications. Lodging caused by storms can ...
levels above 250 bu/acre (Figure 4). An Iowa State University study comparing corn yield response to plant population across soils with different corn suitability ratings found similar results. The most productive soils tended to have a higher optimum population for maximum yield (Woli et al., ...
