| Popis: | 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. |
