Seed quality parameters (Germination percentage and seedling vigor index) of rabi sorghum seeds influenced by rice weevil infestationa

Abstract

Sorghum (Sorghum bicolor (L.) Moench) is an important food and fodder crop of India and which ranks fourth after wheat, rice and maize and serving as a staple food for millions of people particularly in semi-arid tropics of the world. Rice weevil is economically important storage pest on sorghum and other cereals in tropics and sub-tropics of the world. Rice weevil infestation alone resulted in sorghum grain loss of 61.3 per cent over a period of five months.1
