The objective was to develop a plant-process corn yield forecasting model and examine how effective these forecasts might be in improving corn yield forecasts made at the state and crop reporting district level in Iowa. This study was conducted in light of recent budget cuts by the National Agricultural Statistics Service (NASS) and elimination of the reporting of district corn.

Hanoi Medina, Di Tian, Ash Abebe, On optimizing a MODIS-based framework for in-season corn yield forecast, International Journal of Applied Earth Observation and Geoinformation, /, 95, (), (). Crop yield data (Fig. 1b) of Corn and Soybean for Iowa state have been used, Corn crop is planted in early May, growth in biomass occurs from June to September and is ready for harvesting in ore, temporal annual average of NDVI, soil moisture, surface temperature and rainfall (RF) data for period May to September have been used in the present analysis for 19 years from . The primary objective of this paper is to develop yield and price forecasting models employed in informed crop decision planning—a key aspect of effective farm management. For yearly yield prediction, we introduce a weather-based regression model with time-dependent varying coefficients. In order to allow for within-year climate variations, we predict yearly crop yield using .
