Fixed Time N management
In fixed time N management strategy, N fertilizers are applied at certain fixed stages of cassava cultivation. Following the blanket recommendation of Nair et al. (2004), fixed time N management recommends to broadcast half the dose of N fertilizer at the time of final land preparation and the remaining quantity need to be applied in short bands around each plant 45-60 days after planting. The main disadvantage of fixed time N management is that the time of N application is not based on the real time of crop need for nitrogen which can vary from field to field.
