Description
Summary:Sufficient rainfall during the growing season, high fertility of the soil and appropriate temperature regime lowered the influence of spatial heterogeneity on final crop outcomes due to optimal water and nutrition uptake. The results of studies based on remote or proximal optical sensors offer a vast number of vegetative indices which could be used in the prediction of crop maturity, yield potential, plant health estimation, detection of weeds and pests, etc. [...]measurements of apparent electrical conductivity (ECa) using electromagnetic induction (EMI) give information related of soil physical properties, and it is broadly used to delineate management zones of yield potential (Bramley, 2001; Rodrigues et al., 2015; Quinta-Nova and Ferreira, 2020). [...]yield maps were generated using the data collected by the harvester monitors. Since the absolute accuracy of yield monitor varies with different wheat varieties due to uneven grain properties, which cause different response of the embedded sensors, the collected yield values were post-calibrated to reduce possible data discontinuity.
