| Resumo | On most areas where agriculture is developed in Uruguay, soil properties are highly variable in space and as a result the conditions for crop growth are also highly variable. Farmers have interest in knowing final yield pre-harvest as well as the existing spacial variability to decide management practices during the growing season. The objective of this study was to evaluate a method to optimize a simple crop model (pySAFY) to predict leaf area index through the assimilation of time series of Landsat images and later use the calibrated parameters (at the pixel level) to estimate pre-harvest yield and crop growth. The model used is based on the SAFY model (Simple Algorithm for Yield estimate), which was developed by Duchemin (2008), however major changes were made in the model to represent nitrogen accumulation and remobilization in the above ground biomass, which is restricting yield more than other factors represented in the original SAFY (water and heat stress). Both Landsat 7and 8 images free or nearly free cloud acquired during the growing season were used. The study sites were located at 33°3444S latitude and 58°1006W longitude in the south west of Uruguay and were planted with wheat. The model allowed to predicted average yield and spacial variability with acceptable accuracy. Yield was overestimated in areas of the field where Landsat 7 images have SLC gaps or underestimated in areas identified as low yield potential areas. Spacial (30x30m) and temporal resolution of Landsat was not enough to attain high accuracy in predicting micro variability. The method proved useful to use images readily available and allowed to predict pre-harvest yield with enough precision for most practical purposes. |
