Field experiments were conducted at Sugarcane Research Station, Cuddalore, Tamil Nadu during 1995-96 and 1996-97, to integrate tillage and herbicides to control weeds with special reference to Cyperus rotundus in sugarcane. The results revealed that the preplant application of glyphosate @ 2 kg ha'' (with 2% ammonium sulphate)plus three disc harrowings followed by pre-emergence application of atrazine 1 kg or alachlor 1.5 kg ha+hand weeding at 60 DAP recorded 92% weed control efficiency and increased the cane population (50%), cane yield (91%) and sugar yield (86.6%) over farmers method of three disc harrowings and hand weeding twice at 30 and 60 DAP.
