Abstract

Sorghum is the fifth most important cereal crop which is known for its drought resistance character and is referred as major millet. There are many limiting factors that contribute to reduction in yield of the crop, one among them are insect pests. The recently introduced polyphagous pest, fall armyworm is of great threat due to its high defoliating capacity which can cause high yield loss. A field experiment was conducted at AICRP on Sorghum, MARS, Dharwad to evaluate the impact of Spodoptera frugiperda on the yield of rabi sorghum, namely for two varieties, SPV 2217 and CSV 29R. The results revealed that there was maximum FAW infestation in SPV 2217 (48.75 and 9.17%) than CSV 29R (40.83 and 5.42%) in unprotected and protected conditions, respectively and SPV 2217 (8.23q/ha) experienced more yield loss as compared to CSV 29R (7.22q/ha)

Fall armyworm, Rabi Sorghum, CSV 29R, SPV2217, Yield loss

Conclusion

The present study concluded that the higher yields were observed in CSV 29R in both protected and unprotected conditions while the avoidable yield loss due fall armyworm ranged from 18.98 per cent in CSV 29R to 22.21 per cent in SPV 2217. However there was a significant difference in the yields of protected and unprotected conditions whereas no significant difference was found between the yields of both the varieties
