Growth and productivity of wheat as influenced by weed management

Wheat (Triticum aestivum L.) is the most important staple food crop of India. Wheat is the predominant Rabi season crop of north central and upper peninsular region of country. About 20-25% of the area under wheat is infested with narrow and broad leaf weeds, resulting in yield loss of 30-50% (Singh and Ghosh 1992). Shortage of labourers at right time to control weed by hand weeding has become difficult and uneconomical. Some herbicides like 2,4-D, isoproturon and new broad spectrum herbicides like metribuzin and sulfosulforon have great importance in controlling weeds very effectively. To test the efficacy of these herbicides alone and in combination, an experiment was planned.
