Field experiments were conducted to study the effect of integrated weed management practices on growth, regeneration and tuber viability of purple nutsedge in okra for two years during summer seasons at College of Agriculture, Vellayani, Thiruvananthapuram, Kerala, India. Eleven treatments tested in RBD with three replications were combinations of stale seedbed with glyphosate application and black polythene mulching, eucalyptus leaf mulching and cowpea smother cropping in relation to weed free and weedy check. Among the treatments, stale seedbed combined with pre-plant application of glyphosate 1.5 kg/ha (before sowing okra) followed either by polythene mulching or directed application of glyphosate 1.5 kg/ha between rows of okra was the most effective treatment in controlling nutsedge tuber production. Tuber viability and regeneration were lowest under stale seedbed in combination with pre-plant followed by post-emergence directed application of glyphosate or black polythene mulching. A combination of stale seedbed with glyphosate application followed by black polythene mulching was the best treatment for nutsedge management in okra.
