Weeds can be seen everywhere during the growth of the crop, it fiercely battles with crops for water and nutrients, strongly disturbing the normal growth of the crop and resulting in severe yield loss and quality reduction. In the current setting, herbicide spraying appears to be the simplest and most cost-effective method of weed management in South Asian countries. The adverse effects of herbicides on human health and the environment, on the other hand, necessitate the use of a non-chemical weed control strategy. Herbicide dangers, crop weed associations, the key period of crop-weed competition, and various organic weed control approaches applied specifically to crops. Many mechanical weed control methods in crops were effective but labour expensive, whereas biological treatments gave the most protection against specific weed species. In conjunction with other measures, the cultural strategy significantly decreased the weed population in the agricultural area. To limit pesticide usage and ensure long-term production, a nonchemical integrated weed control strategy is advised. Researchers may be able to apply non-chemical weed control in crops to give farmers with meaningful, sustainable, and ecologically acceptable solutions to the problem of weed infestation in the crop, as well as significant yield enhancement. Moreover, herbicides are an exhaustible resource, so new approaches to merging soil conservation and non-chemical weed management are needed. Non-chemical weed management is defined as the control of weeds in the field without using chemical products. Some positive aspects of non-chemical weed control are: the reduction of environmental impact, the maintenance of low but stable weed population, improvement of soil nutrients and water quality.
