Results of field experiment carried out during Kharif 2011 and 2012 at Instructional Farm, Rajasthan College of Agriculture, Udaipur, indicated various weed-management treatments significantly enhanced N and P uptake by maize (Zea mays L.) and reduced removal of nutrients by weeds as compared to weedy check. Maximum saving of 52.96% nitrogen and 51.87 % phosphorus was achieved with oxyfluorfen 0.15 kg/ha pre-emergence fb one hoeing 30 DAS. On pooled basis, this treatment gave 163.57% and  95.86%more grain and stover yield, respectively compared to weedy check, which was followed by metribuzin 0.25 kg/ha pre- emergence fb one hoeing 30 DAS. The yield as well as uptake of N and P by the crop was maximum with 150% RDF which were statistically at par with 125% RDF.
