Organic city wastes are recycled to prepare composts with improved physical properties and enriched with nutrients for their better utilization. Combined application of composts along with inorganic fertilizers may sustain crop productivity and soil fertility. Present study was conducted to assess the impact of 3 city waste composts (2 non-enriched and 1 enriched with 25% N requirement of crop) on the economical utilization of urea in wheat. Generally, fertilizer application along with compost increased the yield, N and P uptake by wheat compared to the fertilizer alone. Performance of the treatments was found in the order: NEC (nitrogen enriched compost) + fertilizer greater than non-enriched compost + fertilizer greater than fertilizer. The NEC along with lower fertilizer-N rate (75 mg per kg soil) was found at par with that of the highest fertilizer rate (175 mg N per kg soil) alone. The results showed that the use of NEC (200 mg per kg soil) for wheat production could be
