Diversified crop rotations have been suggested to reduce grain yield losses from the adverse climatic conditions increasingly common under climate change. Nevertheless, the potential for climate change adaptation of different crop rotational diversity (CRD) remains undetermined. We quantified how climatic conditions affect small grain and maize yields under different CRDs in 32 long-term (10-63 years) field experiments across Europe and North America.

- The study analyzed the physical properties of 19 wheat cultivars with similar protein content to understand how these traits affect grinding performance.
- The wheat kernels were pulverized using a laboratory hammer mill, and the energy required for grinding varied between 120 kJ/kg and 159 kJ/kg.
- Significant correlations were found between physical properties like kernel hardness, vitreousness, and ash content with grinding energy, leading to the development of a multiple linear regression model to predict the average particle size of the ground wheat.
Background: Organic crops are often thought to contain more phenolic secondary metabolites than conventional ones. This study evaluated the influence of organic and conventional farming on concentrations of phenolic acids in spring and winter wheat cultivars.
Results: Five phenolic acids were identified: ferulic, sinapic, p-coumaric, vanillic and p-hydroxybenzoic acid.
