<p class="style25"><span class="style3"><span class="style21">Abstract</span>: A field experiment was conducted at agronomical research farm of Birsa Agricultural University, Ranchi during rainy season of 2009 with the objective to find out the effect of establishment and weed control method on weed dynamics, growth and productivity of rice under wet land situation. The treatment comprised of 4 methods of crop establishment i.e. transplant, SRI, drum seeded and broadcast in main plot and 4 methods of weed control – pyrazosulfuron 0.02 kg ha<sup>-1</sup> PE + mechanical weeding at 25 DAS or DAT, weeding by cono weeder at 25 DAS or DAT, hand weeding at 25 and 40 DAS or DAT, and weedy check in sub plot. The result revealed that among establishment and weed control methods, transplant and application of pyrazosulfuron 0.20 kg ha<sup>-1</sup> + one mechanical weeding at 25 DAS or DAT were most productive. Application of pyrazosulfuron 0.20 kg ha<sup>-1</sup> + one mechanical weeding at 25 DAS or DAT in transplanted or drum seeded or broadcasted rice was most effective in suppressing weed population and weed dry matter accumulation thereby producing higher rice grain yield compared to other weed control methods.</span></p>
