Abstract: During kharif seasons of 2010 and 2011, fieldrnstudies were conducted to assess the influence of age of seedling and weedrnmanagement practices on weeds and yield of rice in System of ricernintensification under temperate conditions at Mountain Research Centre forrnField Crops, Sher-e-Kashmir University of Agricultural Sciences and Technologyrnof Kashmir, (SKUASTK) Khudwani, Anantnag J & K, (India) on silty clay loamrnsoil, normal in reaction having medium fertility status. Major weed speciesrninfesting the field were; Echinocloa crusgali L., Echinocloa colona L., Cyperusrniria L., Cyperu sdifformis L., Marsilia quadrifolia L., Potamogetonrndistinctus., A. Benn., Ammania baccifera L. and Monochoria vaginalis. Thernresults revealed that planting 15 days old seedlings resulted in better croprnestablishment that produced more number of panicles resulting in higher grainrnyield with an advantage of 13.2 per cent over planting of 10 days oldrnseedlings. Comparatively higher density and dry weight of weeds was recorded inrncrop planted with 10 days old seedlings. Weed control through cono-weedingrn(four times) recorded lower number and dry weight of weeds and  proved to be significantly superior in termsrnof grain yield with a yield advantage of 10.6 per cent over two timesrncono-weeding.
