Abstract: A field experiment was conducted during the winter season of 2001-2002 to evolve a suitable weed management practice in winter irrigated cottcm. The experimental soil was loamy sand, slightly acidic (pH S.7), low in organic carbon (0.39%1), and available nitrogen (233kg N/ha), mediwn in available phosphorus (20.7 kg P20,!ha) and high potaaaiwn (202 kg K20/ha). Ten treatment combinations i.e. paraquate dichloride @ 0.2. 0.3 and 0.4 kg/ha as post-emergency directed, spray at 30 DAS, fluchloralin @ 0.8 kg/ha as per-plant soil incorl>oration, alachlor @ 1.0 kg/has as per emergence application at 1 DAS, paraquate dichloride 0.2 kg/ha followed by hand weeding 60 DAS, tluchloralin@ (0.8 kg/ha) followed by hand weeding 40 DAS, alachlore (l.O kg/ha) with hand weeding 40 DAS, hand weeding twice at 20 and 40 DAS, and tmweeded control were tested an cotton MCU-S in a randomized block design with three replications in plot size 8m x Sm. The crop was sown on 26111,November 2001. An uniform fertilizer dose of 120 kg nitrogen, 17.2 kg P and 33.2 kg K/ha along with FYM St/ha was . applied in all the plots. The crop was grown under irrigated conditions with need based plant protection measures.
