In Bihar, rain between the last week of Sep and the first week of Oct helps boost rice productivity. But, when this rain is accompanied by gusty wind, crops lodge. In 1985, rain during the second week of Oct was accompanied by high wind velocity. The loss in yield among cultivars of different maturity groups were assessed. Maximum yield loss was 55% in IET7251 - the crop lodged 1 wk before flowering - followed by Sugandha, which lodged at booting. Among the semidwarfs, maximum yield loss was in Radha that lodged 1 wk before flowering, followed by Pankaj that lodged either at flowering or at booting. Minimum yield loss was in Sujata that lodged 10 d after flowering.
