Among these...

Introduction:
The random forest (RF) machine learning model has been applied successfully for crop yield prediction in recent years (Silva et al., 2023). But extrapolation of predictions to other areas or other years where the feature space or time is considerably different from that of the training data very likely produces unreliable results (Wadoux et al., 2021). Yield measurement error...

Intercropping, i.e. growing two or more crops together on the same land simultaneously is becoming more common in Europe in recent years, especially in organic farming and low-input in production systems. Cultivation of legumes together with cereals in intercropping reduces mineral nitrogen need due to nitrogen biologically fixed by leguminous plants, thus also reducing the expenses on...

Rice blast, caused by the fungus Pyricularia oryzae, is the most important disease of rice globally. Variety mixture has proven potential to reduce the incidence of rice blast and increase yield, but the effectiveness of variety mixture as a disease control method varies, and the general effectiveness and yield benefits of this agroecological practice have not been demonstrated. Here, we...
