1. Winter Annual Weeds Affect Nitrogen Availability for No-Till CornWinter annual weeds effects on nitrogen availability have not been adequately studied. The objective of this study was to determine winter annual weed s effects on nitrogen availability for rainfed no -till corn (Zea mays L.) following soybeans ( Glycine max L. Merr.). Field research was conducted in 2010-2011 at 14 sites with heavy winter annual weed pressure in eastern Kansas. A two -factor factorial arrangement in a randomized complete block design with three replications included t hree herbicide... |
2. Winter Annual Weeds Effect on Corn Response to NitrogenThe timing to control winter annua l weeds is a management concern for producers. In regards to corn response to nitrogen, the objective was to determine how important the timing of winter annual weed control is for no-till, rainfed co rn production following soybeans by assessing: soil water and nitrate; early growth and nitrogen uptake of corn; nitr ogen status of corn at silking- blister; and grain yield. Field research was conduc ted in 2010 at seven locations in Kansas. There were four different... |
