The study compared the aggregate agricultural productivity between the Low External Input Technology (LEIT) and High External Input Technology (HEIT) Farms in Imo State of Nigeria. The state is divided into three agricultural zones, out of which two were randomly selected for the study. Using a multistage sampling technique, 80 LEIT farmers and another 80 HEIT farmers were randomly selected, giving a total sample size of 160 farmers. The result of Chow F- test showed that the LEIT farmers who used animal manure had a higher aggregate agricultural productivity than the HEIT farmers who used inorganic fertilizer. It is therefore recommended that policies geared toward more production and utilization of animal manure be put in place by the government.
