- Pale-colored plants with orange-yellow interveinal chlorosis on older leaves and later on younger leaves.
- Chlorosis progresses to yellowing and finally necrosis in older leaves in severe cases.
- Leaf number and leaf length are greater in Mg-deficient plants,and Mg-deficient leaves are wavy and droopy due to an expansion in the angle between the leaf sheath and leaf blade.
- Reduced number of spickelets.
- reduced grain quality(Fe toxiity may be more pronounced where Mg is part of multiple nutrient deficiency stress involving K,P,Ca,and Mg.s)
