Abstract: An experiment was conducted during the kharif seasons of 2015 and 2016 at Norman E. Borlaug Crop Research Centre, G.B. P.U.A&T, Pantnagar, Uttarakhand to to study the physiological parameters and nitrogen uptake on yield and economics of direct seeded rice and brahmi intercropping system and also best weed management practice for the system as a whole. The result revealed that the all the growth parameter were found significantly higher in sole rice (pendimethalin fb cyhalofop-butyl fb one hand weeding at 45 DAS) which was found at par with paired (2:1) ratio along with pendimethalin fb cyhalofop-butyl fb one hand weeding at 45 DAS while in brahmi crop, sole brahmi (3 hand weedings at 30, 45 and 60 DAP) treatment recorded significantly higher value of growth parameters. Maximum nitrogen content and uptake were recorded in sole rice (pendimethalin fb cyhalofop-butyl fb one hand weeding at 45 DAS) and sole brahmi (3 hand weedings at 30, 45 and 60 DAP) treatment in crop rice and brahmi. Highest rice grain yield was found in sole rice (pendimethalin fb cyhalofop-butyl fb one hand weeding at 45 DAS) and highest brahmi dry herb yield in sole brahmi (3 hand weedings at 30, 45 and 60 DAP). Maximum net returns and benefit cost ratio were recorded in alternate (1:1) ratio along with pendimethalin fb cyhalofop-butyl fb one hand weeding at 45 DAS.
