Abstract

Experiments were conducted during 1987-88 in summer seasons at the Cotton Breeding Station, Tamil Nadu Agricultural University, Coimbatore; to evolve suitable weed management practice for olitorius jute cv.JRO 524. Herbicides viz. fluchloralin, fluazipop-p butyl and pendimethalin were compared with conventional method of hand weeding twice at 21 and 35 days after sowing and unweeded check. The plots hand weeded twice recorded the lowest weed dry matter and higher plant height, basal stem diameter and green plant weight in both years. Among the herbicides, fluchloralin 1.0 kg/ha applied as pre-plant spray at three days before sowing combined with one hand weeding at 35 days after sowing and at three or seven days before sowing recorded comparable yield with hand weeding twice during 1987 and 1988 respectively. The herbicide pendimethalin was the least effective to jute in both years.
