Water is life for all the living organisms which is present on earth. Water is needed to ensure food security, feed livestock, and take up industrial production and to conserve the environment. Water scarcity involves water stress, water shortage or deficits, and water crisis. This may be due to both nature and humans. Main factors that contribute to this issue include poor management of resources, lack of government attention, awareness and anthropogenic waste. The increased value of solid wastes and other hazardous waste in water systems such as rivers, ponds, lakes and canals also heavily pollute the water quality. Government has to take stringent steps for the protection of natural resources because human being is dependent on environment for every basic needs and life is beyond imagination without natural resource like water.

The review paper is based on the effect of various herbicides in weed management of wheat (Triticum aestivum L.)-Chickpea (Cicer arietinum L.) intercropping system. Weeds are considered most harmful to the crops. They interfere with crops during the different growth stages and reduce the growth and yield of the crop drastically. Therefore, different weed management practices have been taken to decrease the crop-weed competition, especially by using herbicidal treatments. So in reference to the weeds found in the wheat-chickpea intercropping and their control, various herbicidal treatments are used to check the weed competition with crops. The chemical weed control method is the most effective and time saving. The herbicides should be selected properly on the basis of selectivity, so they do not harm the main crop. Pre-emergence like Pendimethalin are translocated herbicide, they are applied in the soil and inhibit the cell division in the weed seeds. Post-emergence herbicides like Isoproturon, clodinafop-propargyl, pinoxaden etc are contact herbicide, they enter through aerial parts like leaves and affect the photosynthesis (photosystem-I, II). All these herbicides were proven to be efficient in reducing weed density, dry matter accumulation of weeds and increased the yield and net returns of main crop grown in the field.
