A greenhouse experiment was conducted in rabi 2009 to study the effect of neem cake (NC) at various N levels on yield and nutrient uptake by wheat. The dry matter yield of wheat increased significantly with the application of NC up to 0.125% and N upto 60 mg/kg. Wheat responded to N application up to 60 mg/kg added N in absence of NC. However, in presence of NC, the dry matter yield of wheat increased significantly up to 60, 60 and 20 mg N/kg when NC was applied at 0.125, 0.25 and 0.5%, respectively. The uptake of NPK by wheat increased significantly with increasing levels of N up to 60 mg/kg and neem cake upto 0.125%. Available N, P and organic C content of post-harvest soil samples increased with the increasing levels of N and NC. But the available K content of soil decreased with the application of N and increased with the application of NC.
