Performance of Various Herbicides with and Without Hoeing in Controlling Weeds in Jute (Corchorus olitorius L)1

In field experiment conducted in jute (Corclioms olitorius L) the highest weed control efficiency (WCE) was found in treatment with two hand Weeding (86%). The treatment of flupzifop-p-butyl 0 188 kg/ha as post-em. (21 das), ffuchloralin 1.0 kg/ha as ppi (2 d b s) and pendimeihalin 0.75 kg/ha as ppi (2dbs)al l followed by two hoeings (25 and 35 d a s) provided 56.7ⁿ", 49% and 37% weed control efficiency, respectively. The plots treated with fiuchloralin 10 kg/ha, (ppi) followed by two hoeings gave high fibre yield. Among herbicides, fluchloralin followed by pendimeihalin (as ppi) and fluazifop-p-butyl as post-em. weie promising, giving comparable yield with the conventional method. Fibre yield of jute was reduced to the tune of 1968 kg/ha and 1227 kg/ha due to weed competition in unweeded check plots in 19S6 and 1987, respectively.
