Tillage practices and weed control treatments had marked effect on weeds density and total weed dry matter production in wheat. The' lowest density of Phalaris minOl; CVilodon doelylon. Cvperus rOlundus. Anagallis orvensis and Chenopodium album was rccorded in zero tillage. The maximum density of weed species was observed in conventional tillage. Weed dry matter production was significantly less in zero tillage and more in conventional tillage. Sulfosulfuron at 33.3 g ha" had minimum density of all the major weeds and dry matter production by weeds. Conventional tillage recorded maximum number of carheads n1"'. grains pcr carhead. test weight and grain yield. whieh were minimum in zero tillage treatmcnt. Sulfosulfuron recorded maximum values of all the yield attributes and gave highest grain yield.
