An investigation was conducted on agriculture research farm, School of Agricultural Sciences, SGRRU in Dehradun district to evaluate the different weed management practices on growth and yield of lentil during the Rabi season of 2018-2019-with four replications and nine treatments to investigate the impact of manual, herbicidal and integrated treatments. The treatments constituents quizalofop ethyl @ 55gm, ha as PE, imazethapyr @ 37gm/ha as PE, Chlorimuran ethyl @ 4.5 gm/ha as PPI, pendimethalin @ 1.5 kg as PE, Pendimethalin + Imazethapyr (ready – mix) @ 0.20 kg /ha, Pendimethalin + Imazethapyr (ready – mix) @ 1.5 kg a.i/ha as PE, Pendimethalin @ 1.5 kg/ha as PE + Hand weeding at 40 DAS, Hand weeding thrice at 35, 65 and 90 DAS and control plot. The highest grain and straw yield were recorded 1865 kg/ha and 3099 kg/ha respectively during T8 treatment and the lowest 1380 kg/ha and 2582 kg/ha of grain and star yield was recorded during T3 treatment. The prominent weeds found in the experimental plot were Cannabis sativa, Cynodon dactylon, Chenpodium album and Parthenium hysterophorus: and these weeds together consituted 57 percent of the total weed population.
