Abstract

Tomato (Lycopersicon esculentum Mill) is a perishable nutritive fruit vegetable with high organic
acid content. It is a C3 plant which explains its low yield due to photorespiration. However, the
productivity of the plant is enhanced by the use of fertilizers. The experiments were conducted at
the Directorate of University Farms (DUFARMS), Federal University of Agriculture, Abeokuta
(FUNAAB), between 2014 and 2015 to evaluate the effects of fertilizer type on tomato
productivity. Two nutrient sources were investigated: NPK 15:15:15 (300 kg/ha); Poultry manure
(20 t/ha) and the Unfertilized plots, as the control were assessed in growing tomato variety Roma
VF using a Randomized Complete Block Design replicated three times. Data were collected on
plant height, leaf area, number of flowers, fruit yield and unit fruit weight. Data were subjected to
Analysis of Variance and the mean values were separated using Least Significant Difference at
5% probability level. Plants grown using poultry manure had taller plants, more leaves, more
branches and more flowers. Plants treated with NPK 15:15:15 had higher yield and unit fruit
weight in 2014 than 2015. However, there was no significant difference in the yield and unit fruit
weight across treatment. In 2015, plants treated with poultry manure had higher yield and unit
fruit weight than plants grown using NPK 15:15:15 and plants from the unfertilized treatment.
