Weeds would have a tough time competing against crops such as corn, grains and beans if farmers were to alter their sowing patterns, experts say. "Our results demonstrate that weed control in fields is aided by abandoning traditional seed sowing techniques. Farmers around the world generally sow their crops in rows. Our studies with wheat and corn show that tighter sowing in grid patterns supresses weed growth. This provides increased crop yields in fields prone to heavy amounts of weeds," states an author and plant ecologist.
