EFFECT OF POTASSIUM CHLORIDE ON GROWTH AND ACCUMULATION OF METAL MICRONUTRIENTS IN RICE SEEDLINGS GROWN HYDROPONICALLY

A greenhouse experiment was conducted to observe the effect of potassium chloride (KCl) on rice (Oryza sativa L. cv. Hitomebore). The plants were grown up 14 days after treatments (DAT), with 0, 10, 20 and 30 mM KCl. It observed that seedlings highly sensitive KCl salinity, especially producing toxicity symptoms growth reduction. Iron concentration though increased significantly in shoot increasing medium, it however, decreased root at treatment. Manganese Cu both treatments, Zn treatments. sensitivity metal micronutrients followed general trends Mn> Cu> Zn> Fe K as compared medium.
