Purpose: The paper compares the effect of five different direct seeding methods to the conventional tillage on the emerging and yield of silage corn (Zea may L.) in two different pedo-ecological condi...
Understanding temporal variability in crop yields has implications for sustainable crop production, particularly since greater fluxes in crop yields are projected with global climate change.
Nitrogen fertilizer is a key ingredient for growing a good corn crop. It is not unusual for a well-fertilized crop to yield more than twice as much as an unfertilized crop. But how much nitrogen shoul...
