Field experiment was conducted at the Student's Research Farm, Department of Agronomy, Punjab Agricultural University, Ludhiana during rabi 2005-06 to evaluate the feasibility of different weed management options in bed planted wheat. Amongst different weed control methods integration of one interculture with post emergence application of clodinafop 40 g ha-1 on bed tops only produced highest wheat grain yield which was at par with bed planting treatment given, two interculture and bed planted crop, two interculture+hand pulling of Phalaris minor at earing stage of wheat. Dry matter of Phalaris minor was lower in chemically treated flat sown and bed sown wheat whereas broad leaf weed dry matter was highest in clodinafop @60 g ha-1 treated flat sown wheat followed by bed sown crop treated with same herbicide.
