A field experiment was conducted during March-June (Kharif), 2015 at Annamalai University Experimental farm, Department of agronomy, Tamilnadu, India to study the effect of management of weeds in pearl millet based intercropping system. The experiments were laid out in split-plot design replicated thrice with three main treatments viz., Sole pearl millet (M1), Pearlmillet + Cluster beans (M2) and Pearl millet + Moth beans (M3) and four sub treatments viz., Unweeded control (S1), Twice hand weeding (S2), Pendimethalin 0.75kg ha-1 (S3) and Alachlor 0.1 kg ha-1(S4). Among the cropping system Pearlmillet + Cluster beans influenced the growth and yield components of Pearl millet such plant height, LAI, drymatter production and recorded the lowest value of growth and yield components were recorded under sole Pearlmillet. Among the weed management practices, twice handweeding recorded the higher growth and yield components and the least weed population, weed biomass, highest weed control efficiency, weed smothering efficiency by weeds over the unweeded control. The growth, yield components and yield of both the intercrops such as plant height, LAI, DMP were high in twice hand weeding followed by Pendimethalin 0.75kg ha-1 over unweeded control.
