?EFFECT OF GAMMA IRRADIATION ON GROWTH AND NUTRIENTS UPTAKE OF SORGHUM PLANTS

Abstract

A pot experiment was carried out using sandy and calcareous soils to study the effects of gamma irradiating doses
for sorghum seeds on dry matter yield and elemental uptake. Three cuttings were taken during the experiment every 40
days. Results showed that 4 Kr. dose was the best dose that caused significant higher increase of dry matter yield and
nutrients uptake for three cuttings under both types of soil. Gamma irradiation doses at 8 Kr. and above all had an adverse
affect on dry matter yield and nutrients uptake, especially under calcareous soil.
