The focus of this year's edition of Cereal Campo Demo will be nitrogen use efficiency (NUE). NUE is often defined as the conversion rate of the input of N (for example, fertilizing N applied and/or N of the soil) in the total biomass of the plant or the specific biomass of the plant organ (for example, the wheat yield). Wheat will be cultivated at three different levels of nitrogen: 100% (as the industry practice), 25% and 50% less. In conditions with reduced nitrogen, several biostimulants will then be applied to evaluate the specific contribution of each to the growth of the crop in terms of chlorophyll content, yield and qualitative traits (proteins, starch, gluten, sedimentation value through the Zeleny test, hectoliter weight and hardness).
