Boron Deficiency in Rice

The first symptoms are seen on the youngest leaves which do not elongate properly but remain short and narrow. A faint white/yellow chlorosis may possibly develop near the leaf tip. The next emerging leaves will be folded, bent, and almost white. If such leaves open up, a large part of the blade will quickly dry up. When the deficiency is severe, growth stops completely.

The older leaves initially remain dark green but later many white chlorotic spots are likely to develop on both young and old leaves. New tillers may develop but these quickly show the same symptoms and remain stunted. Complete failure to set seed has been observed under severe boron deficiency. Roots of severely affected plants are stubby, tough and light brown in color.
