Plant Crops Production in Asia
Genga A
Most crops showing damage had already headed, although crops suffered some damage at all growth stages. In many fields the damage was so great that growers abandoned the crop. The loss in grain yield ranged from 10% in moderately affected fields to 70% in those severely affected. The damage to the standing crop sometimes reached 100%. The estimate was arrived at by adding losses of various degrees in different areas.
