Intervention effect Trifluralin, pendimethalin and linuron applied to soil gave effective control of dominant weeds in lentil.
Intervention effect Integrating linuron 0.75 kg/ha with one hand weeding at 45 DAS was more phytotoxic to weeds than herbicide alone.
Observation Maximum seed yield of lentil in weed-free plots was 1204 kg/ha in 1994-95.
Observation Maximum seed yield of lentil in weed-free plots was 1304 kg/ha in 1995-96.
Intervention effect Season-long weed competition caused a 73 and 79% yield reduction relative to the weed-free treatment.
Observation Post-emergence linuron at 0.75 and 1.0 kg/ha was phytotoxic to lentil.
