Abstract
Field experiments were conducted during Kharif season of 2007 and 2008 at research farm of the department of Agronomy, PAV, Ludhiana, Punjab, India to find out the appropriate plant density and most effective weed control method for controlling weeds in direct seeded rice (Oryza saliva L.) under unpuddled conditions. Higher plant density i.e. 250 viable seed m· 2 (50 kg ha1 } provided good smothering potential on weeds thus reducing the dry matter of weeds. But maximum grain yield was recorded with planting density of 150 viable seeds m· 2 (JO kg ha1 ) during both years, which was significantly higher than I 00 viable seeds m· 2
