abstract
A field experiment was conducted during Rabi season of 2017-18 and 2018-19 at Chaudhary Charan Singh Haryana Agricultural University, Hisar with an objective to assess the avoidable losses in chickpea variety HC-1 caused due to Helicoverpa armigera. The results showed that the mean number of larvae per meter row length were significantly less at p<0.05 being 6.50 times lower under protected conditions (0.54) as compared to that of unprotected conditions (3.51). The mean number of damaged pods per plant were 2.34 times less under protected conditions (6.59) compared to 15.45 damaged pods under unprotected conditions. The mean per cent pod damage was 2.84 times higher under unprotected conditions (27.88) to that of 9.79 percent pod damage under protected conditions. Mean yield (kg) per hectare was 2.0 times higher in protected conditions (2013.66) as compared to that under unprotected conditions (1005.78). An avoidable yield loss of 49.61 per cent was recorded in grain yield (pooled).
