Abstract
As a follow-up to our earlier investigation on the effect of gamma radiation on the germination and growth of certain Nigerian agricultural crops, the present study sought to determine the effect of gamma radiation on the grain yield of Zea mays (maize) and Arachis hypogaea (groundnut). The seeds were planted after irradiation without the application of fertiliser. The results show that for maize, grain yield for irradiated samples is increased to levels above the unirradiated yield at doses up to about 250 Gy with the optimum yield occurring at 150 Gy. The corresponding increase for groundnut is observed at doses up to about 930 Gy with optimum yield at a dose of 300 Gy. Inhibition in yield was observed to set in at a dose greater than 250 Gy for maize and 930 Gy for groundnut. The actual relationship between mean yield of these crops and gamma radiation dose was obtained using sixth-degree polynomial equations.
