Optimizing root yield of cassava under fertigation and the masked effect of atmospheric temperature.

Background: Fertigation is a rare and an expensive method of fertilizer application to cassava, and hence there is a need to optimize its efficiency for profitability. This study's objective was to optimize root yield of cassava through fertigation using a logistic model.

Results: The field treatments were six fertigation concentrations against three cassava varieties, selected according to their maturity period.
