A field study was conducted on the Aridisols during the winter seasons (rabi) of 2001–02 and 2002–03 to evaluate suitable herbicide for management of weeds in blond psyllium (Plantago ovata Forsk.). Application of oxadirgyl @ 50 g/ha 15 days after sowing (DAS) recorded maximum seed yield (1,833 kg/ha) and net returns (Rs 25,244/ha) closely followed by pre-emergence application of isoproturon @ 600 g/ha which gave seed yield of 1,729 kg/ha and net returns of Rs 23,1220/ha. Due to phytotoxic effect on the crop, oxyfluorfen applied @ 50 or 75 g/ha 15 DAS remained inferior to oxadirgyl 50 g/ha applied 15 DAS.
