摘要

Wheat (Triticum aeslivum L.) is second most important staple crop after rice. It is predominant Rabi season crop of northern, central and upper peninsular region of the country. Among the various factors responsible for low productivity of wheat, weedinfestation during early stages of growth is one of the major factors. Due to initial slow growth, it provides a congenial environment for weed growth. In wheat generally, first 30 to 40 days are highly critical from the point of crop weed competition.Mechanical weeding is costly, time consuming and sometimes not possible due to non-availability of labour. Under such a situation, chemical weed control offers a better alternative to manual weeding during early stage. Since, meagre information is available on the comparative efficiency of different herbicides for weed control, weeds before critical period of crop-weed competition.
