A CRITICAL STUDY ON WEED CONTROL TECHNIQUES

Abstract

Weed is a major problem in crop production, affecting the crop
yield as well as the quality of harvested produce. Weeds compete with the
main crop for soil nutrients (NPK) of worth Rs 5,000 crores per year in India.
The value of total crop losses due to weeds is around Rs. 10,000 crores (Rao,
2000). Weed control is one of the most difficult tasks in crop production
agriculture that accounts for a considerable share of the cost involved in
agricultural production. There are many methods for weed management, but
out of those methods, chemical methods are the most popular. These methods
are hazardous for the environment as well as for human health. To ensure
food security and sustainable development of agriculture, it is critically
important to develop chemical and pollution-free agricultural products. This
study has been carried out to know the different weed controlling techniques
used by the different researchers to be adapted in agricultural work
