Weed competition is maximum during the early stages of groundnut crop because of slow initial growth and less foliage cover.
As the crop do not grow tall weeds dominate during later part of crop growth also.


Tall weedsWeeds in groundnut crop not only compete with the crop for nutrients, water, and light, but also interfere with harvesting of the crop. Unless good weed control is achieved, substantial yield losses will occur. A reduction of 20 to 45% in yield due to weeds was reported from weed control experiments.
The critical period of weed competition is estimated to be 2-6 weeks after sowing. A variety of weeds are associated with groundnut crop. These weeds comprise of diverse plant species of annual grasses and seasonal broad leaved weeds.
