Effect of linear view approach of weed management in agro-ecosystem: A review

February 2021

Weeds are considered a pest that is detrimental to human interest. Weeds compete with cultivated and desirable plants for space, soil nutrient, and sunlight and soil moisture thereby reducing crop productivity. Weeds also serve as a host for pests and pathogens that cause plant diseases. Weeds typically produce large numbers of seeds, assisting their spread, and rapidly invade disturbed sites. Seeds spread into natural...
