Estimating harvest date of corn in the field. Crop Science, 1996, 6(3): 227-231.Schmidt JL, Hallauer AR (1966) Estimating harvest date of corn in the field. Crop Sci. 6: 227-231.SCHMIDT J L, HALLAUER A R. Estimating harvest date of corn in the field. Crop Science, 1966, 6(3)...
Early and accurate information of crop growth condition is vital for agricultural industry and food security, which gives rise to a strong demand for timely monitoring crop growth condition and estimating crop yields. This study selected the remotely sensed leaf area index (LAI) and vegetation temper...
After parameters were estimated, the CERES-Maize model correctly predicted the dry matter yields, anthesis dates, and harvest dates. The mean values of these variables were close to those measured in the field, with an average relative error of 4.4% and 2.4% for the data sets of 2005 and ...
The temperate continental climate yields four distinct seasons in the study area, and diverse vegetation and soil kinds are present. The woodland is located southeast of Lake Dalai Nur (43.3°N 116.6°E) at 1500 m elevation and is covered by both broadleaf forest and needle leaf forest, e....
We use pre‐harvest forward contract bids from 1977 to 2013 in Illinois to estimate the cost of forward contracting corn and soybeans. Prior to 2007, it cost 1.55% of the October spot price or 3.74 cents/bushel on average to forward contract corn at the end of February. In 2007–2013,...
(2020) found that LSTM outperformed the RF model in estimating county-level corn yields in the United States [32]. The superior performance of LSTM over two ML approaches was further proved during the prediction of wheat yield in the Guanzhong Plain by Tian et al. (2021) (e.g., support...

(adj. R² between 0.32 and 0.5). The models were spatially applied and resulted in a yield estimation map at household level, enabling predictions of up to 2 months prior to harvest. The map links yield on a 10-m spatial resolution to households and consequently can display potential food...
Studies have shown that these algorithms can predict county-level yields up to four months in advance of harvest [18,19,20]. However, it needs a lot of historical data to be trained, and the outcomes of the training on a particular period and region cannot be extended to other times and...
