Cluster bean, Cyamopsis tetragonoloba Imazethapyr,  Pendimethalin, Residual effect, Succeeding crop

A field experiment was carried out at Punjab  Agricultural University, Regional Research Station, Bathinda during Kharif 2012. Pendimethalin 750 g/ha followed by imazethapyr 40 g/ha results minimum weed intensity and weed dry matter accumulation and maximum yield attributes and yield except weed free. The application of pendimethalin 750 g/ha followed by imazethapyr 40 g/ha resulted maximum net return (` 33,118/ha) and b:c ratio (2.07) which was more than other treatments of weed control. Imazethapyr, imazethapyr + imazamox, quizalofop-ethyl, fenoxaprop-p-ethyl and pendimethalin at all doses and combinations resulted no phytotoxicity symptoms on guar crop and no residual effect on succeeding wheat crop.
