Computer-implemented techniques for determining and presenting improved seeding rate recommendations for sowing hybrid seeds in a field. In an embodiment, seeding query logic receiving digital data representing planting parameters including seed type and sowing row width. The seeding query logic retrieves a set of one or more seeding models from a data repository based on planting parameters. Mixture model logic generates an empirical mixture model in digital computer memory that represents a composite distribution of the set of one or more seeding models. The mixture model logic then generates an optimal seeding rate distribution dataset in digital computer memory based upon the empirical mixture model, where the optimal seeding rate distribution dataset represents the optimal seeding rate across all measure fields. Optimal seeding rate recommendation logic calculates and presents on a digital display device an optimal seeding rate recommendation that is based upon the optimal seeding rate distribution dataset.
