Abstract: A field experiment was carried out during kharif season of 2012 at the Research Cum Instructional Farm, Indira Gandhi Krishi Vishwavidyala, Raipur to find out appropriate sowing date and weed management practices of blackgram. The experiment was laid down in split plot design with three replication. There were three date of sowing assigned in main plot and the weed management practices assigned in sub plot The soil of the experimental field was clayey in texture (Vertisols) with low N, medium P and high K content. Result revealed that the highest plant population was recorded under August 9 sowing over rest of sowing dates. Significantly the higher yield and its attribute was noted under August 9 sowing over other dates tested. Among the weed management practices, application of imazethapyr 35 % + imazamox 35 % (Odyssey 70 WG) @ 75 g ha^-1 + HW at 35 DAS (W₆) produced significantly higher yield and its attribute. However, it was found at par with pendimethalin (PE) @ 1 kg ha^-1 + HW at 25 DAS (W₄). Among different weed management practices, application of imazethapyr 35 % + imazamox 35 % (Odyssey 70 WG) @ 75 g ha^-1 + HW at 35 DAS (W₆) performed better over other weed management practices under the agro-climatic condition of Chhattisgarh plains.
