    abstract = {Performance of carrots varies with levels of fertilizer application. As a root crop, maintaining high root
yield requires knowledge of the optimal fertilizer requirement, especially, when production soil type is
characterized by gravels indicating low moisture retention ability. Reduction in the loading of galvanized soil
with inorganic fertilizer is crucial in enhancing soil moisture retention and growing healthy food crops with
minimal chemical residue. This study was conducted at Landmark University during growing season of 2015
and 2016 to assess the differential response of three carrot genotypes to different levels of organic and
inorganic fertilizer application in Southern Savanna Zone. The experiments were conducted using a randomized
complete block design with three replications. Data collected on leave number, fresh leave weight, plant height
and fresh root weight were subjected to analysis of variance. Difference between means were partitioned using
duncan multiple range test at 5% probability level (p = 0.05). The study revealed that at application of 1 t/ha of
organic fertilizer, the three carrot genotypes responded differently and significantly for fresh root yield. At all
levels of both organic and inorganic fertilizer applications, the three carrot genotypes responded differentially
for root yield either significant or non-significant at different levels of fertilizer application. This study identified
that growing ibaka oma and ohama oma carrot genotypes under the organic manure regime (1 and 2 t/ha)
highest root yields of 40.87, 41.48 and 41.58 t/ha. These identified genotypes can be grown organically for
health benefits in guinea savanna ecology.}
