Abstract: A field experiment was conducted to study the performance of pre and post emergence herbicides on nutrient removal and Uptake in Tomato cv. Arka vikas during rabi 2011-12 and 2012-13. The experiment consisted of 10 treatments of Pre and post emergence herbicides (Pendimethalin, Oxyflourfen, Imazethapyr and Quizalofop ethyle) and their combinations which were replicated in Randomized block design. All the weed control treatments significantly influenced nutrient removal by weeds and Nutrient uptake by tomato plants. Pre emergence herbicides coupled with Quizalofop ethyle found to be on par with Hand weeding. Though Imazethapyr applied as post emergence effectively controls the weeds but found to be extremely toxic to the crop. The maximum yield of tomato was recorded with Hand weeding, which is on par with the application of pre emergence herbicides combined with Quizalofop ethyle @ 75g a.i per ha
