An evaluation of nitrification retardation property of Citrullus colosynthis cake and its influence on yield and N uptake by wheat. Citrullus colosynthis oilcake was tested as nitrification retarder under laboratory and greenhouse conditions. The same showed NH4-N conservation when applied at the rate of 5 and 10% by weight of urea. Higher rate (20%) of the cake resulted in NO2-N accumulation leading to lower N recovery by wheat.
