Abstract: A field experiment was conducted at Krishi Vigyan Kendra, South Tripura during the kharif (wet) season of 2013 and 2014 to study the influence of different weed management practices on weed population dynamics of direct seeded upland rice under Tripura condition. The experiment consisted of twelve treatments laid out in randomized complete block design with three replication. Among the various treatments ICAR (RC) for NEH Region, Umiam, Meghalaya, pendimethalin at 1.0 kg ha-1 at 2 DAS + bispyribac sodium at 25 g ha-1 at 20 DAS (T4) recorded the lowest number of all weed in both the years followed by pendimethalin at 1.0 kg ha-1 at 2 DAS+ one hand weeding at 30 DAS(T3). At 60 and 90 DAS, lowest weeds population was recorded by hand weeding thrice at 15, 30 and 45 DAS (T11). The highest net return and benefit cost ratio was observed with the treatment pendimethalin at 1.0 kg ha-1 at 2 DAS + bispyribac sodium at 25 g ha-1 at 20 DAS (T4).
