Effects of artificial ultraviolet (UV-C) radiation (254nm) on the growth and yield of Solanum lycopersicon (tomato) accession NGB 01301 were studied. Viable seeds were irradiated with handheld UV lamp (model UVGL 55; Science company, USA) for 0, 10, 20, 30, 40, 50 and 60 min. Treated seeds were sown in plastic buckets at the screened house of the Botanical garden of the University of Ilorin, Nigeria in five replicates. Quantitative data were obtained at maturity, 20 WAS (Weeks After Sowing) and subjected to Analysis of variance using SPSS 16.0 for Windows. Highest germination (93.33%) was obtained in 30 min treatment and the lowest (63.33%) in 10 min exposure. Maximum plant height (53.37 cm) was recorded in 10 min while the least (47.60cm) was in 60 min treatment. Petiole length was highest (2.40 cm) in treatment for 10min, treatment with 50 min produced least petiole length (1.37±0.26 cm). With respect to leaf parameters, optimum performance was recorded in 30 min treatment. However, highest performance in response to UV irradiation with respect to petiole length, number of branches and leaf number occurred in 10 min treatment. Among the exposure time evaluated, 30 min produced early maturing plants with highest fruit yield.
