Keywords magnetohydrodynamics (MHD) –turbulence –Sun: activity –Sun: magnetic fields We introduce on/offintermittencyinto amean field dynamo model by imposing stochastic fluctuations in either the alpha effect or through theinclusion of afluctuatingelectromotivef orce. Sufficiently strong smallscalefluctuations with time scales of theorder of 0.3–3 years can produce long term variations in thes...

متن کاملCorn yield and yield stability under varying nutrient management, crop rotation, and rainfall
Long-term yield performance and yield stability of common cropping systems needs to be simultaneously assessed at various fertility regimes. Based on a consecutive 19-year field trial, including eight fertilization treatments with different combinations of nitrogen (N), phosphorus (P), potassium (K) and recycled manure (RM), the effects of fertilization and crop rotation on corn (Zea mays L.) y...
