Observation Rotataindica, Fimbristylis miliacea, Ageratum conyzoides, Cyperusiria, Polygonum barbatum and Cynadon dactylon were the major weeds under both DSR and TPR.
Observation Paspalum distichum and other listed weeds were minor weeds in the rice fields.
Observation Rotataindica was the major weed under TPR.
Intervention effect US-382 had the highest weed population under TPR, at 131.7 per m2.
Intervention effect The weed population of US-382 was completely absent under DSR.
Intervention effect Cynadon dactylon was completely absent in the weeded region under TPR.
Intervention effect Cynadon dactylon was highest in the weeded field of DSR for US-382, at 18.7 per m2.
Intervention effect Biomass was lowest in the weeded field of NR-10490 under TPR.
Intervention effect Grain yield was highest in the weeded region of US-382 (7.7 t/ha).
Association Rice yield decreased gradually as weed biomass increased.
Recommendation The authors recommend effective weed control management to increase rice productivity.
