Abstract

An experiment was conducted to evaluate the effect of NITROGEN FERTILIZER and DROUGHT STRESS at different GROWTH STAGES on PRUSSIC ACID content of-sorghum in Agricultural Research Station of Gorgan in 1997.The experiment was carried out in pots under controlled conditions. Treatments comprised of three levels of N fertilizer (0,3 and 6 gr N/pot simulating control, 100 and 200 kg N/ha respectively) and DROUGHT STRESS which was applied on four GROWTH STAGES of sorghun (7-8 leaf stage, flag leaf appearance, heading stage and control). Treatments were arranged factorially and were compared in a Randomized Complete. Block Design with three replications. For each DROUGHT STRESS treatment, irrigation was stopped at the beginning of the expected growth stage and re-started when the signs of temporary wilting were seen in plants (soil moisture pressure equal to-17 bars). After DROUGHT STRESS, plants were irrigated normally. PRUSSIC ACID content significantly in creased at vegetative and generative GROWTH STAGES of SORGHUM due to NITROGEN FERTILIZER application. SORGHUM responded more severely during vegetative GROWTH STAGES to NITROGEN FERTILIZER than generative stage. In heading stage only the maximum NITROGEN FERTILIZER level significantly increased PRUSSIC ACID content more than control. DROUGHT STRESS 'at different GROWTH STAGES and the interaction effect of DROUGHT STRESS X NITROGEN FERTILIZER levels had no significant effect on PRUSSIC ACID content of SORGHUM.
